Not only the passive cooling make the Epever weight. Also the quality and dimensions of the toroidal inductor! Epever use very large and robust toroidal inductor. And they cover all the toroidal inductor with resin to cooling better. Epever mppts are extremely well assembled. No doubt.
Informative video, I recently purchased the Powrmr (60 amps) charge controller, and its been serving me well on my 1200 watts pv setup. I feel more confident using it after watching your reviews.
Running 30a and 40a epever looking for long term efficiency. Remote location dc power. I have been really happy with mppt over pwm. I’ll spend the extra for epever just so I don’t have to worry about what won’t wrong or what I have to replace.
I have the MakeSkyBlue v123 which is good for 60A charging. Mine does well until it says my panel voltage goes from 56V down to 13V. My power goes from 430W down to 40W in less than a minute. It varies a lot but those are average values.
Slug are a big problem around here. They did burn 2 of my MakeSkyBlue and likely will have done the same with PowMr. Adult slug enter by the pretty large gap between the connectors terminal and the aluminium box on the right side. Then, they go die on the copper coil... that is shorted after that.
Holy crap that is insane man. I guess they are going for the heat? I hate slugs they eat my garden. You need some iron phospate aka. sluggo or slug stopper.
@@robertjackson151 We do use sluggo on the farm, about 100 lbs per year. Here, they are invasive specie. However. We are suspecting the wild Rabbit and some bird to eat the pellet. We think they get sick. So, we limit the sluggo to very specifics areas. We have tried a few tonnes for a few years, hoping to reduce the population. We did not see any change.
@@jylfarm1964 There are two types of slug killer one with some toxic chemical starting with M, the other is environmentally friend and contains only Iron phosphate. You can also buy little slug pellet houses to put the pellet in to keep animals out and makes it last a lot longer. I made some out of yogurt cup glued together with holes for the slugs.
@@robertjackson151 We use Sluggo Pallet. They are supposed to be safe for the wild life, but the rabbit look sick, not dead. We have tried numerous thing. Our biggest success was chicken train to eat them (That not natural for chicken to eat them). However, we can't have chicken legally sharing the space with edible crop that will be sold. (The dejection are not composted).
Not to mention both the MSB and PowMr had higher output than the EP ever,, so his "efficiency " rating is nonsense and missing critical data, EG; solar input on each unit
The voltage conversion efficiency alone doesn't tell much if the MPP tracker adjusts the input voltage badly. My own experience is that the losses due to bad MPP tracking and conversion in cheap charge controllers are so high that a direct connection of solar panels to the battery is more efficient if the voltages match roughly. E.g. I've connected two 48 cell solar panels in series (Voc=64V) to a 15 cell LiFePO battery (~50V). With this configuration I do not even need a diode for blocking reverse current in the darkness, as the battery voltage seems to be low enough (at least at around 15 deg celsius).
I tore down a PowMR, and the mosfets are affixed to a slab of aluminum that is only held to the back with 4 screws, no thermal compound or pad between the aluminum slab and the rear of the unit. If the fan is annoying you could tear it down and apply compound between the back of the case and the aluminum slab.
With no cooling system , the EPever shuts down when it gets hot (or melts down) and goes to pwm, and does the same in shaded conditions. Costs nearly 3 times as much, and is HUGE for what it can do. The PowMr is prone to overcharging and the cooling fan burns out much quicker than the more modern and updated Make Sky Blue versions 118 and above. All 3 are great lower cost investments compared to midnight classic and outback, But Only Make Sky Blue is constantly evolving and improving their chips and bios.
I'm a big fan of the EpEver - The unit modulates should it get near full rated current and fethers down the charge to ovoid overheating - mine goes into PWM mode only when the solar falls below 10watts to reduce internal driver loads - mine charged 0.6a on a clear night from a full moon - as mined located in a cubard i did fit extra vents
hey man @335, we can see the input to the charger controller is 398 watts, and your shunt says 371 watts, making the efficiency 93.3%. am i missing something? where did you get the 356watt number from? same with @3:37, the shut numbers are different than what you have one screen. thanks for the video, i bought one of these about a month ago and havent hooked it up yet
Yes I noticed a discrepancy in my shunt that threw the numbers off by a certain percent. Hence the adjusted numbers on the screen compared to the video footage.
@@jasonbrown467 from my tests I believe they are measuring the input power from the panels. Not taking into account efficiency losses before power goes to the battery. I have seen some that are so optimistic though that a 400w panels shows 430w. That’s just some miscalibrated something inside. Has to be...right?!
That EPever is huge. I have a used 2500watt array and need to get some charge controllers as my morningstar pwms are rated 30v max and panels are 37v. We had 5 days of no power and could of been better if my array was hooked up.
I currently want to run a 12v system since I lost a 48v inverter after 5 years. Either of these should be fine with a string at 72v. The thing is I may only be able to put 2 or 3 250 Watt panels on a 60A CC since I'm running at 12v correct? I'm shooting for the cheaper units as I could get 2 vs 1 epever. Do you recommend the blue or powmr after a few months.
@@cutweldngrind I haven't gotten finished testing the 60a version of the MakeSkyBlue. At the moment it appears the only reason to go MSB is if you want the features. Such as wifi monitoring. If you just want a simple charge controller PowMr seems like a reasonable choice.
I'm wondering how the efficiency changes when the PV voltage is higher. In theory, the larger the difference between input and output voltage on a buck converter, the lower the efficiency.
@@BeeneEnergy Thank you for your response! That is really strange, but happy to hear. This was the only reason why I was considering wiring 2x455W, 50voc panels in parallel in my 24V system, but that makes no sense now. Still a bit afraid of the 105V max input for a 24V system on the PowMr 60A. Not sure if that is 105Vmpp or 105Voc. Any experience with this?
@@DrenImeraj If you’re that close you should keep it in parallel. 105v is voc so you’ll be bumping against it in cold weather. I realize that depends on your climate too but here in Texas I wouldn’t recommend it in series :).
@@BeeneEnergy Ahh, makes sense, thank you! Do you know the behavior of the controller when that is exceeded? Is there potential for a catastrophic failure?
@@DrenImeraj Potential, yes I'm sure. I've observed it go just barely over voltage and the controller just stopped charging and threw an error for high PV voltage. I'm sure if it was high enough it'd burn something up.
Can i use 800 w 12v panels on the 60A charge controller? Since the controller is 95 percent efficient, and the fact that the panels are not 100 percent efficient.
My PowMr fan burned out in 2 months under max solar panel loads, the MSB is still going strong. PowMR is just a MSB prototype, version 113, older, less refined, and prone to overcharging , especially on smaller battery banks. MSB is just better.
Apparently the PowMr is over reading the current out, when display says 60A out is actually only 40A it also is gets very hot. the EPEver is bigger as it needs to be to be reliable, the PowMr is a 40A controller not 60A this is called FRAUD its a copy of MakeSkyBlue and both are cheap and poor efficiency EPEver brand is bigger more expensive and actually works properly it may never overheat.
Good day boss, I have 2x180 12v solar panels connected in parallel to produce 360w at 12. With my pwm 30A charge controller I could only get 12 to 14 A max so I changed to mppt powmr 60A, I can only get 190w at 13.5v max I guess 14.4 A currently. My cable size is 2x10AWG blue black cable. My location is Africa Nigeria, what could be the problem, cos my 160 watt panel produced 156 watts about 11A .
Hi. Could you help me with something?, I been looking into those controllers you are using in you video but i need to be 100% sure they can charge 36v battery packs?, i have alot of them from ebikes and i need a controller but can't find anything showing they can charge that voltage battery!... Thanks.
Thoughts: This converter does have current limiting built in. So it shouldn’t self destruct in that scenario. It’s designed to use the battery as a buffer load of sorts, so it will have a hard time keeping voltage at 48. Might fluctuate too much especially when adding loads to the inverter. I wouldn’t recommend it. But it might be possible.
Thought of another piece. The charge controller needs a 48v battery connected in order to auto detect what voltage range to output. Otherwise it might default to 12v?
@@BeeneEnergy Thanks for your input. Doesn't look like I could use it as a buck converter then. Do you know of any 72v to 48v bucks that can handle at least 40A output? I have a 48v inverter and a pair of 48v ebike batts I'm using for backup power, would like to use my collection of ryobi 40v batts in series as well with the inverter.
I’m not happy with my MSB 60a controller. I returned my 1st one because the lcd always acts up, flashing between program/setup mode and my settings. I’m on my 2nd one and it’s happening again. It was running great the 1st week, but now it is acting up again. This one burned out one of my 2 pole breakers. I feel as if it is running too hot. The room is cool in temperature. I have 650w of solar and it read on the msb lcd display an additional 2.3kw today on a clear day. I’m in Southern California, USA. The pv wattage input reads 15% higher than actual. My 1st one that I returned read 35% higher. I tested both with my clamp meter and multi meter. Does any of your msb controller do any of the things that I described? Or did I just get 2 bad ones? I just found someone selling an epever 60a locally. I might give that one a try.
I have had the Optimistic readings with this style of controller. Could you tell me about your setup? Voltage of panels, series or parallel, battery voltage, etc?
@@BeeneEnergy 12v reliable 3000w inverter. 2 120ah lifepo4 in parallel. 2 x 325w solar panels wired in series. Total voc 80v, but usually stays between 55-75v. My msb flickers between program/setup and regular display when it starts producing more than 300w of pv input. My msb is wired with dual pole dc breakers. Since I am using lifepo4, I set the controller at 14.4v on both D01 (float) AND D02 (max). D03 low voltage @ 12.2v. D04 disabled. I calibrated the D06 to match my battery bank.
@@BeeneEnergy update. It’s still doing that LCD flickering back and forth thing. But it’s been performing a lot better the last 2 days. It’s been doing 3.3kw per day the last 2 days. I guess I’m going to keep monitoring, until I have to replace it. There’s someone selling a used/like new Victron 100/50 for $200 locally. I’m considering buying it.
Hey man, pretty sure I bought a few Jinko 305w panels from you in Ft Worth, Christopher right?. Anyhow here's my experience, the EPEvers are a great product, they last, are reliable, and just work properly. The company I work for does some off grid solar installations with AI surveillance, and telecommunications equipment. Before switching to the EPEvers we had constant problems. We use mostly the 30amp units. IMO well worth the extra $$ to have something that works, and lasts. BTW that PwrMr company really irked me recently, I ordered a Growatt 3000w 24v hybrid inverter from them on ebay, and they immediately tried to pull a bait and switch on me saying the inverters needed to be tested, but they can ship me a 48v instead. They kept stringing me along, and pushing that on me. I don't trust them, they didn't even give me a chance to trust them, gave me a bad experience right from the get go. BTW If you have a few more of those jinko 305's let me know.
Wow that’s nasty, I have had a source from China not have any of a product in stock and I had to wait a couple weeks for manufacturing to keep up. So it’s possible the testing comment is true. But they really shouldn’t have the product listed on eBay if it’s not available :(. Yes I sold a bunch of those 305w Jinko’s. We have some 310w REC right now that are about the same size, but none of those Jinko’s since that batch. I’ve been playing with Growatt inverters and they seem like good units.
@@BeeneEnergy Sweet, are they 72 cell? BTW I'm the guy that wrote the code, and developed the BMS unlock for Jehu Garcia's scooter batteries. featured here: th-cam.com/video/UmXgEoOm5y8/w-d-xo.html I'm going to start doing some reviews myself, trying to find the time.
@Brad Cagle Yes they are 72 cell modules. Oh yeah I don't watch all his videos but I saw that one, knew there was someone watching out for him! How did you find what the BMS needed? Did you get a hold of a bike/scooter that used those batteries? I love recycling like what Jehu does with batteries. I've purchased a lot of batteries from batteryhookup but nothing where I had to trick the BMS to get going, always kept it simple.
@@BeeneEnergy I don't remember which forum, but there was some scooter forum where a guy had a complete scooter and he monitored the data being sent to the BMS. I just wrote some code for Arduino that would send that that data to the BMS. I do the same kind of reverse engineering a lot at work, I'm a software engineer and we have to integrate with existing systems that customers may have. What are you asking for the panels?
@@BradCagle very nice! One of the things on my list is figuring out how can communication works with inverters and BMS’s to see how it can be better utilized. We are asking $110 for the 310w panels. They are new old stock, sat on pallets in a field for a bit.
Epever is one of the best cheep cheese brand of mppt controller. Victronenergy or morningstar are better, but amongst the Chinese brands epever is one of the best. I use epever tracer for 4 years. Now, I switch to victronenergy smartsolar mppt and is even better. In 4 years I have seen max 305 watts with a 300w panel with epever. Now I see often 320/330 watt with victronenergy.
I’d go for the epever of these three as it’s passively cooled and a tad more efficient. Aka won’t bug you by making noise and will make the most of the limited panels you can install.
@@campervan-vlad I have not used one of those but it looks slick. Looks like primary use case is keeping starting battery topped off and healthy while also charging leisure battery.
nice work, although I'm not entirely sure that your test setup for efficiency is ideal. You also neglect to discuss the importance of component quality and longevity of the systems when comparing the EPEVER to the PowMr ... case fans don't often fail but still I've seen some of these units on reviews catch on fire. I think also a bit more specifics on the test setup (perhaps in writing in the description) would be helpful. By this I mean things like; battery state of charge, how many amps its drawing, panel config (Voc Vmaxp Isc and stuff like that) Hats off
@@moldycupbleachpower6782 all three of the ones in this video are MPPT. They all have dc to dc conversion happening internally. I can hook a 49voc 10a isc panel up to the powmr and get 300-400 watts of charging. If it was pwm I’d be limited to 120w max.
Nice to see someone finally including the Make Sky Blue in testing, because they blow away everything I have put against them. As a user of PowMr and MSB, I'd say your test left out FACTS, like how many panel watts were hooked up to each unit, if it was the same array on each, the PowMR and MSB blew away your EPever in efficiency because of higher overall input. PS, your video audio is out of sync , quite strange.
I must be reading something different than you. I tested these with a single 400w panel and with two, hence two readings for each. Epever did better in both situations. MSB tied in one and did better in another compared to powmr. What conditions were you In where the MSB did amazing?
@@BeeneEnergy Spring, winter and Fall cool weather production from 800 watts in panels into a 12 volt battery bank produces constant 90-100 % solar panel input on the 60 amp, at max load. But your video is putting 800 watts on a 40 amp MSB, on a 12 volt bank? It cannot handle that, sorry, your missing so much data, seems you set it up to promote your website PowMr, and EPever sales, and skew MSB, which beats them both , easily in long term. The EPever overheats and goes to pwm, and uses pwm in shaded conditions, so many flaws in it, your not considering at all
@@BeeneEnergy PowMR is just a version 113 Make Sky Blue and kept overcharging my AGM, going over 15.1 volts and triggering my inverter to shut down . The PowMr fan blew out in 2 or 3 months, my MSB under same load is on its 4th year now, never overcharges, and completely destroys the EPever in cloudy, or max input situations due to efficient cooling system. These things matter.
@@affordablesolarguy Hmm I’m still not understanding. I measured how much energy the charge controller would pull off the panel(s) vs how much made it to the battery to get my efficiency number. How would you suggest I do it? The MSB actually did best when it had 800w of panels available to it.
After powmr was not use for a one year, become broken and buttons dont work. Also they are much slower and have ability to stuck in low power point insteed cheking it. I much happer with Makeskyble 118v for doing all fast and no need power off then changed a paramitets.
Powmr and makeskyblue are the same, only rebranded... Victron can make better results then epever but it is two expencive. Now im thinking about this new all in one devices, its much less complicated then mppt, inverter, lot of shunts, cables, low voltage protection and so on...
You also put two 49 voc panels through the Powmr and Make Sky blue into a 12 volt battery bank. If these panels are running in series you went 18 voc over the maximum voc on a 12 volt battery bank. I sure hope no one takes advice from you, its amazing both units did not explode during the test,, or did they? On a 12 volt battery bank, both units are max at 80 voc, but can push 160 voc, and 2,800 watts on a 48 volt battery bank. They are extremely versatile in comparison to the dinosaur Epever which saves itself from constant overheating with weaker tracking and pwm safe mode, which reduces "efficiency " dramatically .
You are over excited and making accusations. If you calmly came to me with claims or suggestions I’d be happy to address them. What makes you say my epever can’t handle a 48v battery for example? That’s asinine. Ever heard of over paneling? The Chinese manual for a powmr doesn’t address it but in my observation it’s a current limiting device so having more than 720w is ok if within the voltage range. The powmr even has circuitry to shut down if voc is too high. I’ll say the epever I blew up didn’t! Of course with the epever I sent 90v in when its max was 50. Please explain your claim that the MSB will blow the epever out of the water. I’ve got a 60a v119 now along with a powmr and epever. And a whole assortment of batteries I could connect! I will say, I plan to run these tests with a higher voltage battery to see if efficiency really does go up when the panel voltage is closer to battery voltage.
@@BeeneEnergy Ok, here is the issue, you don't know anything about solar, your an actor, your deceptive, you just showed people how to do what the manual specifically states to NEVER do, and that puts people homes and lives in danger of burning down. You showed them how to properly blow up their equipment, and you did not show the line loss connections you had on any of the equipment, and you had HUGE line loss on the MSB and PowMr. Your lack of attention to detail, and inability to follow directions makes you dangerous to aspiring do it yourselfers. If your focus was to help people instead of make money, you would follow directions and demonstrate safety and compliance with user manual instruction. The Make sky blue and Powmr out perform the EPever easily , especially when you realize you can buy 3 for the price of 1. So dollar for dollar, buying the EpEver is like throwing money away for people trying to create clean energy on a budget. 60 amp MSB is 100-120 bucks, PowMr 60 amp is 60-80 bucks , and mine are 4 years old, still cost less than the lowliest Epever, and can run over 3000 watts without ANY issues. If you know what your doing.
@@affordablesolarguy This is where i’m confused. Out perform in what way? I ran and grabbed my 24v battery so I could test your arguments. I am all about learning. The only thing so far is that you claim my efficiency numbers are off since the panel voltage was so high. So with a 24v battery my panels will be right below 2x the battery voltage. (25.6v nominal LiFePo4). Right now I have four 400w panels in parallel and I’m testing with the MSB. About to hook up the powmr. Also you seem to be implying I like the epever better. I bit the bullet and bought it to test with, all my setups are using PowMr charge controllers. That’s what I started with and I haven’t been convinced to go with anything else. Unless I’m wanting a hybrid inverter in which case the charging is taken care of. Let’s have a conversation. Let’s go back and forth and figure out the best way to do this. Let’s not yell at each other. That ok with you?
@@BeeneEnergy efficiency is how much of your pv potential makes it to the battery. In your own video , both the MSB and Powmr pull in MORE energy and beat the EP, when they are withing the instruction manual specifications, and beat it substantially. Your loss is due to your shunt, shaudy wiring, and incompetence , in the form of LINE LOSS. Strange how your Epever doesn't suffer this at all, maybe you should show your wiring job , since anyone who owns these units knows , the loss is completely your fault, and probably deliberate. You get bigger bonus's on more expensive units I'm sure. I get constant , 90%+ solar input during cold season, and 75% when panels are hot. Sometimes, I get more power than the panels are rated for in the cold season, because my wiring is correct. DO YOU GET IT? Efficiency is NOT a measure of your incompetence in wiring, its the percentage of pv potential that the controller can harvest.
It is possible with pwm but you lose 2/3 of the panel that way. With mppt I still get the full wattage of the panel. Also it’s hard to find a pwm controller for a 12v battery that won’t implode with a 48voc panel.
@@BeeneEnergy I have been puzzled by the parallel layout of solar panels. Let's say one has 2 parallel branches. One at ~60v with three 100w panels and another branch at ~70v with 2 larger 250w panels. What would happen at the charger controller? Obviously this can happen in reality even when the panels on the two branches perfectly match, because the site can get shade and clouds. The panels has blocking diode so the higher voltage can not flow to the lower branch.?.
Dear Beene. The efficiency measurement must be measured with a 30V working point solar cell. Then we get realistic data. Most solar panels are 30V. Then a completely different result would come out.
Yep lots of 30v panels (60 cell) around. I had someone else saying this as well. My plan is to do a similar video/tests with a 24v battery so that the panel voltage is much closer to battery voltage. I also have some 60/120 cell panels to try as well as these 144 cell panels.
have u ever considered making your own controller? I am, I will shortly start to publish for FREE all my designs with proof they work and any one can make them and save a fortune.
All good quality mppts are heavy! Morningstar 25 amp is 1.4 kg! Epever 40 amp is 1.3 kg. Victronenergy 30 amp is 1.3 kg. Helios ms4830 40 amp with tempered touch screen glass screen is 2. 0 kg. A 60 amp mppt with 1 kg or less is not a quality item, for me
You went over the max input on the powmr 60 amp by 80 watts, and over the 40 amp Make Sky Blue max input by 400 watts . Here is the manual. th-cam.com/video/LLFYDVO9Wx8/w-d-xo.html How is this a realistic comparison? How about trying the same test on a 48 volt battery bank, watch the EPever completely fail to run at all, while the MSB and PowMr can run 12, 24, 36 or 48 volt battery banks, quadrupling their output, and blowing the Epever out of the water, no comparison at higher voltages.
60 amp EP, 60 amp PowMr, vs 40 amp MSB,, seems like a flawed test from the gate to me. How can you post an efficiency rating without data on solar panels hooked up? Flawed comparison all the way around.

Make sky blue manual clearly says that you have to keep the array voc at 1.5-2 times the battery voltage for beat efficiency.
I have the MakeSkyBlue v123 which is good for 60A charging. Mine does well until it says my panel voltage goes from 56V down to 13V. My power goes from 430W down to 40W in less than a minute. It varies a lot but those are average values.

You're back!!
Winter break? Glad Gentle Giant is still keeping an eye on me.
The voltage conversion efficiency alone doesn't tell much if the MPP tracker adjusts the input voltage badly. My own experience is that the losses due to bad MPP tracking and conversion in cheap charge controllers are so high that a direct connection of solar panels to the battery is more efficient if the voltages match roughly. E.g. I've connected two 48 cell solar panels in series (Voc=64V) to a 15 cell LiFePO battery (~50V). With this configuration I do not even need a diode for blocking reverse current in the darkness, as the battery voltage seems to be low enough (at least at around 15 deg celsius).
I tore down a PowMR, and the mosfets are affixed to a slab of aluminum that is only held to the back with 4 screws, no thermal compound or pad between the aluminum slab and the rear of the unit.
If the fan is annoying you could tear it down and apply compound between the back of the case and the aluminum slab.
With no cooling system , the EPever shuts down when it gets hot (or melts down) and goes to pwm, and does the same in shaded conditions. Costs nearly 3 times as much, and is HUGE for what it can do. The PowMr is prone to overcharging and the cooling fan burns out much quicker than the more modern and updated Make Sky Blue versions 118 and above. All 3 are great lower cost investments compared to midnight classic and outback, But Only Make Sky Blue is constantly evolving and improving their chips and bios.
awesome info bro
I'm a big fan of the EpEver - The unit modulates should it get near full rated current and fethers down the charge to ovoid overheating - mine goes into PWM mode only when the solar falls below 10watts to reduce internal driver loads - mine charged 0.6a on a clear night from a full moon - as mined located in a cubard i did fit extra vents

Yes I noticed a discrepancy in my shunt that threw the numbers off by a certain percent. Hence the adjusted numbers on the screen compared to the video footage.
@@BeeneEnergy did you have a theory as to why the numbers are off from the charge controller screen?
@@jasonbrown467 from my tests I believe they are measuring the input power from the panels. Not taking into account efficiency losses before power goes to the battery.
I have seen some that are so optimistic though that a 400w panels shows 430w. That’s just some miscalibrated something inside. Has to be...right?!
Hallo; welcher ist zu empfehlen? Wir haben beide (PowMr und Epever) gekauft und Probleme mit Beiden > beim Einstellen.
Es dankt und Grüßt MR
That EPever is huge. I have a used 2500watt array and need to get some charge controllers as my morningstar pwms are rated 30v max and panels are 37v. We had 5 days of no power and could of been better if my array was hooked up.
Yes it’s massive!
I currently want to run a 12v system since I lost a 48v inverter after 5 years. Either of these should be fine with a string at 72v. The thing is I may only be able to put 2 or 3 250 Watt panels on a 60A CC since I'm running at 12v correct? I'm shooting for the cheaper units as I could get 2 vs 1 epever. Do you recommend the blue or powmr after a few months.
@@cutweldngrind I haven't gotten finished testing the 60a version of the MakeSkyBlue. At the moment it appears the only reason to go MSB is if you want the features. Such as wifi monitoring. If you just want a simple charge controller PowMr seems like a reasonable choice.
Thanks for the review with the efficiency% comparisons. Can you compare those vs PWM in a table as well?
Good
Epever are a bit more expensive too. I'll probably buy another one. I have a 30a and need a 40a for a second system.
Thank you very much, sir.
I'm wondering how the efficiency changes when the PV voltage is higher. In theory, the larger the difference between input and output voltage on a buck converter, the lower the efficiency.
I've actually got another couple videos where I was surprised to see the opposite. Efficiency went up when I ran with a higher voltage!
@@BeeneEnergy Thank you for your response! That is really strange, but happy to hear. This was the only reason why I was considering wiring 2x455W, 50voc panels in parallel in my 24V system, but that makes no sense now. Still a bit afraid of the 105V max input for a 24V system on the PowMr 60A. Not sure if that is 105Vmpp or 105Voc. Any experience with this?
@@DrenImeraj If you’re that close you should keep it in parallel. 105v is voc so you’ll be bumping against it in cold weather. I realize that depends on your climate too but here in Texas I wouldn’t recommend it in series :).
@@BeeneEnergy Ahh, makes sense, thank you! Do you know the behavior of the controller when that is exceeded? Is there potential for a catastrophic failure?
@@DrenImeraj Potential, yes I'm sure. I've observed it go just barely over voltage and the controller just stopped charging and threw an error for high PV voltage. I'm sure if it was high enough it'd burn something up.
Can i use 800 w 12v panels on the 60A charge controller? Since the controller is 95 percent efficient, and the fact that the panels are not 100 percent efficient.
i got epevers biggest model. 100Amp 200v. It is huge! :P
Can you do the same comparison in a 48v setup?

Wow I forget how far we’ve come in such a short period!
I comparing about powmr and makeskyblue. Is powmr often get problem? Is it easily to get hot and fan often turned on than makeskyblue?
My PowMr fan burned out in 2 months under max solar panel loads, the MSB is still going strong. PowMR is just a MSB prototype, version 113, older, less refined, and prone to overcharging , especially on smaller battery banks. MSB is just better.
Apparently the PowMr is over reading the current out, when display says 60A out is actually only 40A it also is gets very hot. the EPEver is bigger as it needs to be to be reliable, the PowMr is a 40A controller not 60A this is called FRAUD its a copy of MakeSkyBlue and both are cheap and poor efficiency EPEver brand is bigger more expensive and actually works properly it may never overheat.
Good day boss, I have 2x180 12v solar panels connected in parallel to produce 360w at 12. With my pwm 30A charge controller I could only get 12 to 14 A max so I changed to mppt powmr 60A, I can only get 190w at 13.5v max I guess 14.4 A currently. My cable size is 2x10AWG blue black cable. My location is Africa Nigeria, what could be the problem, cos my 160 watt panel produced 156 watts about 11A .
Connect your panels in series to the powmr mppt ....you will get more power that way....am in Ghana and I use the same mppt and it's very great
@@ConfusedArchaeology-ig3pjWill the charge controller burn if I give it 2* 410w panel in series…Am also in Ghana
Hi.
Could you help me with something?, I been looking into those controllers you are using in you video but i need to be 100% sure they can charge 36v battery packs?, i have alot of them from ebikes and i need a controller but can't find anything showing they can charge that voltage battery!...
Thanks.
The powmr? Yes it can charge 36v packs.
@@BeeneEnergy Great, thanks.
Thanks man.
Good job. Keep them coming.
Thank you!
Great vid thanks
can you use this on 24v panels with 12 volt batterys with the 119 controller
Yep. Specs should state about 80voc max when using a 12v battery. So two 24v panels in series usually works too.
@@BeeneEnergy thanks very munch i can use my pure sign wave inverter i have 10 230 watt panels 24 volt panels
Subscriber number 8,020 something! as of this post 8/31/24
Would it be possible to use the PowMR as a buck converter? 72v battery input, 48v output to inverter?
Thoughts: This converter does have current limiting built in. So it shouldn’t self destruct in that scenario.
It’s designed to use the battery as a buffer load of sorts, so it will have a hard time keeping voltage at 48. Might fluctuate too much especially when adding loads to the inverter.
I wouldn’t recommend it. But it might be possible.
Thought of another piece. The charge controller needs a 48v battery connected in order to auto detect what voltage range to output. Otherwise it might default to 12v?
@@BeeneEnergy Thanks for your input. Doesn't look like I could use it as a buck converter then. Do you know of any 72v to 48v bucks that can handle at least 40A output?
I have a 48v inverter and a pair of 48v ebike batts I'm using for backup power, would like to use my collection of ryobi 40v batts in series as well with the inverter.
I’m not happy with my MSB 60a controller. I returned my 1st one because the lcd always acts up, flashing between program/setup mode and my settings. I’m on my 2nd one and it’s happening again. It was running great the 1st week, but now it is acting up again. This one burned out one of my 2 pole breakers. I feel as if it is running too hot. The room is cool in temperature. I have 650w of solar and it read on the msb lcd display an additional 2.3kw today on a clear day. I’m in Southern California, USA. The pv wattage input reads 15% higher than actual. My 1st one that I returned read 35% higher. I tested both with my clamp meter and multi meter. Does any of your msb controller do any of the things that I described? Or did I just get 2 bad ones? I just found someone selling an epever 60a locally. I might give that one a try.
I have had the Optimistic readings with this style of controller.
Could you tell me about your setup? Voltage of panels, series or parallel, battery voltage, etc?
@@BeeneEnergy 12v reliable 3000w inverter. 2 120ah lifepo4 in parallel. 2 x 325w solar panels wired in series. Total voc 80v, but usually stays between 55-75v. My msb flickers between program/setup and regular display when it starts producing more than 300w of pv input. My msb is wired with dual pole dc breakers. Since I am using lifepo4, I set the controller at 14.4v on both D01 (float) AND D02 (max). D03 low voltage @ 12.2v. D04 disabled. I calibrated the D06 to match my battery bank.
@@ilingwang1168 That all seems well within spec. Crazy that you are having trouble with your second unit.
@@BeeneEnergy update. It’s still doing that LCD flickering back and forth thing. But it’s been performing a lot better the last 2 days. It’s been doing 3.3kw per day the last 2 days. I guess I’m going to keep monitoring, until I have to replace it. There’s someone selling a used/like new Victron 100/50 for $200 locally. I’m considering buying it.
Hey man, pretty sure I bought a few Jinko 305w panels from you in Ft Worth, Christopher right?. Anyhow here's my experience, the EPEvers are a great product, they last, are reliable, and just work properly. The company I work for does some off grid solar installations with AI surveillance, and telecommunications equipment. Before switching to the EPEvers we had constant problems. We use mostly the 30amp units. IMO well worth the extra $$ to have something that works, and lasts. BTW that PwrMr company really irked me recently, I ordered a Growatt 3000w 24v hybrid inverter from them on ebay, and they immediately tried to pull a bait and switch on me saying the inverters needed to be tested, but they can ship me a 48v instead. They kept stringing me along, and pushing that on me. I don't trust them, they didn't even give me a chance to trust them, gave me a bad experience right from the get go. BTW If you have a few more of those jinko 305's let me know.
Wow that’s nasty, I have had a source from China not have any of a product in stock and I had to wait a couple weeks for manufacturing to keep up. So it’s possible the testing comment is true. But they really shouldn’t have the product listed on eBay if it’s not available :(.
Yes I sold a bunch of those 305w Jinko’s. We have some 310w REC right now that are about the same size, but none of those Jinko’s since that batch.
I’ve been playing with Growatt inverters and they seem like good units.
@@BeeneEnergy Sweet, are they 72 cell? BTW I'm the guy that wrote the code, and developed the BMS unlock for Jehu Garcia's scooter batteries. featured here: th-cam.com/video/UmXgEoOm5y8/w-d-xo.html I'm going to start doing some reviews myself, trying to find the time.
@Brad Cagle Yes they are 72 cell modules. Oh yeah I don't watch all his videos but I saw that one, knew there was someone watching out for him! How did you find what the BMS needed? Did you get a hold of a bike/scooter that used those batteries? I love recycling like what Jehu does with batteries. I've purchased a lot of batteries from batteryhookup but nothing where I had to trick the BMS to get going, always kept it simple.
@@BeeneEnergy I don't remember which forum, but there was some scooter forum where a guy had a complete scooter and he monitored the data being sent to the BMS. I just wrote some code for Arduino that would send that that data to the BMS. I do the same kind of reverse engineering a lot at work, I'm a software engineer and we have to integrate with existing systems that customers may have. What are you asking for the panels?
@@BradCagle very nice! One of the things on my list is figuring out how can communication works with inverters and BMS’s to see how it can be better utilized.
We are asking $110 for the 310w panels. They are new old stock, sat on pallets in a field for a bit.
Epever is one of the best cheep cheese brand of mppt controller. Victronenergy or morningstar are better, but amongst the Chinese brands epever is one of the best.
I use epever tracer for 4 years. Now, I switch to victronenergy smartsolar mppt and is even better. In 4 years I have seen max 305 watts with a 300w panel with epever. Now I see often 320/330 watt with victronenergy.
Hi, what you can recommend for use in 2021 (maybe some nee model) for RV. About 40a
Thank you
I’d go for the epever of these three as it’s passively cooled and a tad more efficient. Aka won’t bug you by making noise and will make the most of the limited panels you can install.
@@BeeneEnergy thank you, what about epever duoracer? What you think?
Looks like it's a ready for double battery setup
@@campervan-vlad I have not used one of those but it looks slick. Looks like primary use case is keeping starting battery topped off and healthy while also charging leisure battery.
@@BeeneEnergy thank you mate
My PWRMR 60A over reports the current quite a bit.
Did the Wi-Fi work?
what about the EAsun
nice work, although I'm not entirely sure that your test setup for efficiency is ideal. You also neglect to discuss the importance of component quality and longevity of the systems when comparing the EPEVER to the PowMr ... case fans don't often fail but still I've seen some of these units on reviews catch on fire.
I think also a bit more specifics on the test setup (perhaps in writing in the description) would be helpful. By this I mean things like; battery state of charge, how many amps its drawing, panel config (Voc Vmaxp Isc and stuff like that)
Hats off
I'm prett y sure the Makesky and the PowMR are the same unit with a different color label.
Whenn the battery is fully charged, the current will be 0 ?
I mean LiFePo4 battery
@@szekerespista3758 yes it would be normal to drop to 0 when full.
@@BeeneEnergy thanks!
Hey mate do you know the difference between a pwm and mppt?
I do indeed, why do you ask?
@@BeeneEnergy I just want sure if the cheaper one was an mppt or a pwm.
@@moldycupbleachpower6782 all three of the ones in this video are MPPT. They all have dc to dc conversion happening internally. I can hook a 49voc 10a isc panel up to the powmr and get 300-400 watts of charging. If it was pwm I’d be limited to 120w max.
Nice to see someone finally including the Make Sky Blue in testing, because they blow away everything I have put against them. As a user of PowMr and MSB, I'd say your test left out FACTS, like how many panel watts were hooked up to each unit, if it was the same array on each, the PowMR and MSB blew away your EPever in efficiency because of higher overall input. PS, your video audio is out of sync , quite strange.
I must be reading something different than you. I tested these with a single 400w panel and with two, hence two readings for each. Epever did better in both situations. MSB tied in one and did better in another compared to powmr.
What conditions were you In where the MSB did amazing?
@@BeeneEnergy Spring, winter and Fall cool weather production from 800 watts in panels into a 12 volt battery bank produces constant 90-100 % solar panel input on the 60 amp, at max load. But your video is putting 800 watts on a 40 amp MSB, on a 12 volt bank? It cannot handle that, sorry, your missing so much data, seems you set it up to promote your website PowMr, and EPever sales, and skew MSB, which beats them both , easily in long term. The EPever overheats and goes to pwm, and uses pwm in shaded conditions, so many flaws in it, your not considering at all
@@BeeneEnergy PowMR is just a version 113 Make Sky Blue and kept overcharging my AGM, going over 15.1 volts and triggering my inverter to shut down . The PowMr fan blew out in 2 or 3 months, my MSB under same load is on its 4th year now, never overcharges, and completely destroys the EPever in cloudy, or max input situations due to efficient cooling system. These things matter.
@@affordablesolarguy Hmm I’m still not understanding. I measured how much energy the charge controller would pull off the panel(s) vs how much made it to the battery to get my efficiency number. How would you suggest I do it?
The MSB actually did best when it had 800w of panels available to it.
Hello, epever 60a...wire came loose on battery bank....oh no!
Thang you
I wonder if the v119 wifi is any different
I’ve got my 60a v119 in, just have to find time to run some tests on it. Will find out soon!
@@BeeneEnergy is it the wifi version I want to see what the app and connectivity is like
@@joshuabest100 yes it’s WiFi. I agree, I am excited to see how good the UI is.
@@BeeneEnergy looking forward to it i have my notifications on
After powmr was not use for a one year, become broken and buttons dont work. Also they are much slower and have ability to stuck in low power point insteed cheking it. I much happer with Makeskyble 118v for doing all fast and no need power off then changed a paramitets.
Powmr and makeskyblue are the same, only rebranded... Victron can make better results then epever but it is two expencive.
Now im thinking about this new all in one devices, its much less complicated then mppt, inverter, lot of shunts, cables, low voltage protection and so on...
Internally they are not the same, even though they appear identical on the outside. There are videos that show the internals of them.
You also put two 49 voc panels through the Powmr and Make Sky blue into a 12 volt battery bank. If these panels are running in series you went 18 voc over the maximum voc on a 12 volt battery bank. I sure hope no one takes advice from you, its amazing both units did not explode during the test,, or did they? On a 12 volt battery bank, both units are max at 80 voc, but can push 160 voc, and 2,800 watts on a 48 volt battery bank. They are extremely versatile in comparison to the dinosaur Epever which saves itself from constant overheating with weaker tracking and pwm safe mode, which reduces "efficiency " dramatically .
You are over excited and making accusations. If you calmly came to me with claims or suggestions I’d be happy to address them.
What makes you say my epever can’t handle a 48v battery for example? That’s asinine.
Ever heard of over paneling? The Chinese manual for a powmr doesn’t address it but in my observation it’s a current limiting device so having more than 720w is ok if within the voltage range. The powmr even has circuitry to shut down if voc is too high. I’ll say the epever I blew up didn’t! Of course with the epever I sent 90v in when its max was 50.
Please explain your claim that the MSB will blow the epever out of the water. I’ve got a 60a v119 now along with a powmr and epever. And a whole assortment of batteries I could connect!
I will say, I plan to run these tests with a higher voltage battery to see if efficiency really does go up when the panel voltage is closer to battery voltage.
@@BeeneEnergy Ok, here is the issue, you don't know anything about solar, your an actor, your deceptive, you just showed people how to do what the manual specifically states to NEVER do, and that puts people homes and lives in danger of burning down. You showed them how to properly blow up their equipment, and you did not show the line loss connections you had on any of the equipment, and you had HUGE line loss on the MSB and PowMr. Your lack of attention to detail, and inability to follow directions makes you dangerous to aspiring do it yourselfers. If your focus was to help people instead of make money, you would follow directions and demonstrate safety and compliance with user manual instruction. The Make sky blue and Powmr out perform the EPever easily , especially when you realize you can buy 3 for the price of 1. So dollar for dollar, buying the EpEver is like throwing money away for people trying to create clean energy on a budget. 60 amp MSB is 100-120 bucks, PowMr 60 amp is 60-80 bucks , and mine are 4 years old, still cost less than the lowliest Epever, and can run over 3000 watts without ANY issues. If you know what your doing.
@@affordablesolarguy This is where i’m confused. Out perform in what way? I ran and grabbed my 24v battery so I could test your arguments. I am all about learning.
The only thing so far is that you claim my efficiency numbers are off since the panel voltage was so high. So with a 24v battery my panels will be right below 2x the battery voltage. (25.6v nominal LiFePo4).
Right now I have four 400w panels in parallel and I’m testing with the MSB. About to hook up the powmr.
Also you seem to be implying I like the epever better. I bit the bullet and bought it to test with, all my setups are using PowMr charge controllers. That’s what I started with and I haven’t been convinced to go with anything else. Unless I’m wanting a hybrid inverter in which case the charging is taken care of.
Let’s have a conversation. Let’s go back and forth and figure out the best way to do this. Let’s not yell at each other. That ok with you?
@@BeeneEnergy efficiency is how much of your pv potential makes it to the battery. In your own video , both the MSB and Powmr pull in MORE energy and beat the EP, when they are withing the instruction manual specifications, and beat it substantially. Your loss is due to your shunt, shaudy wiring, and incompetence , in the form of LINE LOSS. Strange how your Epever doesn't suffer this at all, maybe you should show your wiring job , since anyone who owns these units knows , the loss is completely your fault, and probably deliberate. You get bigger bonus's on more expensive units I'm sure. I get constant , 90%+ solar input during cold season, and 75% when panels are hot. Sometimes, I get more power than the panels are rated for in the cold season, because my wiring is correct. DO YOU GET IT? Efficiency is NOT a measure of your incompetence in wiring, its the percentage of pv potential that the controller can harvest.
Troll
You are use a 48 V solar panel to charge 12V battery is that possible only on mppt solar chargers?
It is possible with pwm but you lose 2/3 of the panel that way. With mppt I still get the full wattage of the panel. Also it’s hard to find a pwm controller for a 12v battery that won’t implode with a 48voc panel.
@@BeeneEnergy then i am good if i have 3* 24v panels to charger 3s battery with powr 60A
Yes just don’t use more than 80voc when at 12v battery. You might need to run those panels in parallel.
@@BeeneEnergy I have been puzzled by the parallel layout of solar panels. Let's say one has 2 parallel branches. One at ~60v with three 100w panels and another branch at ~70v with 2 larger 250w panels. What would happen at the charger controller? Obviously this can happen in reality even when the panels on the two branches perfectly match, because the site can get shade and clouds. The panels has blocking diode so the higher voltage can not flow to the lower branch.?.
Dear Beene. The efficiency measurement must be measured with a 30V working point solar cell. Then we get realistic data. Most solar panels are 30V. Then a completely different result would come out.
Yep lots of 30v panels (60 cell) around. I had someone else saying this as well. My plan is to do a similar video/tests with a 24v battery so that the panel voltage is much closer to battery voltage. I also have some 60/120 cell panels to try as well as these 144 cell panels.
have u ever considered making your own controller? I am, I will shortly start to publish for FREE all my designs with proof they work and any one can make them and save a fortune.
You remind me of Abe Lincoln. Anyone else ever told you that?
You put epever to advantage just by choosing lower solar panels voltage. Not good test at all
ขอบคุณที่แปลเป็นไทยด้วยซับ
All good quality mppts are heavy! Morningstar 25 amp is 1.4 kg! Epever 40 amp is 1.3 kg. Victronenergy 30 amp is 1.3 kg. Helios ms4830 40 amp with tempered touch screen glass screen is 2. 0 kg. A 60 amp mppt with 1 kg or less is not a quality item, for me
I guess the powmr just squeezes into the weight qualification at 1.1kg then!
Hahahaha @ you don't get a bargain for free. Classic
You went over the max input on the powmr 60 amp by 80 watts, and over the 40 amp Make Sky Blue max input by 400 watts . Here is the manual. th-cam.com/video/LLFYDVO9Wx8/w-d-xo.html How is this a realistic comparison? How about trying the same test on a 48 volt battery bank, watch the EPever completely fail to run at all, while the MSB and PowMr can run 12, 24, 36 or 48 volt battery banks, quadrupling their output, and blowing the Epever out of the water, no comparison at higher voltages.
60 amp EP, 60 amp PowMr, vs 40 amp MSB,, seems like a flawed test from the gate to me. How can you post an efficiency rating without data on solar panels hooked up? Flawed comparison all the way around.
