A minor correction... the idle power draw of an inverter has nothing to do with the input voltage. It is mostly just a function of the output wattage the inverter is designed for, as well as the quality of the design and type of inverter.
The *efficiency* of the inverter does have a relationship with input voltage. 48V inverters are typically more efficient than 12V inverters. Though it isn't a huge difference, it does mean that 48V inverters generally run a quite a bit cooler than 12V inverters.
What does hold as a general rule of thumb is to size the inverter only just slightly larger than your max load, to minimize the vampire draw. The vampire draw, particularly from all-in-one units, can be substantial. The vampire draw for discrete inverters is typically quite a bit less.
PowMr wouldn't be my first choice for an all-in-one. I'd look at the EG4 6000XP first. Finally, note that the hybrid inverters are quite useful for their AC handling and battery charging functionality, but in terms of the solar and the inverter you can always slap on additional discrete charge controllers and inverters and not be restricted to the limitations of what is built into the hybrid inverter.
One of the best things about 48V systems is that you can feed a lot of solar into very cheap charge controllers. A cheap little Victron 100/20 can handle 1000W+ of solar on a 48V system.

Thank you for post this video, your explain to me all i need!! Thanks again!!
Unless I missed it, one important safety item he didn't mention is that when yo go to 48V from 12 or 24V you are now in the realm of electrocution hazards, so must be very careful working on the system, making sure things are disconnected/powered off as needed. 50V is apparently the point where DC current can traverse skin, and a charged 48V battery is 51.2V.
You have to try pretty hard to get a shock off 50 VDC. Shock / electrocution hazards are more of a sliding scale of probability than a hard cut off. Yes, if you are soaked and your fingerprints have gone wrinkly 50V is enough to give you a jolt. If you are just a regular dry person it's perfectly safe.
Good video and product explanation.
Great info. Thank you. Can you please do a video showing your solar panel setup for this system. Is it ground mount or on the shed roof?
Thanks so much for your video
Very nice video--very informative. I liked the distribution box, and will probably get one. One question: is this PowMr solar inverter charger UL listed?
Thanks

48V systems do seem a lot more simple to diy. I had been towing with the idea of a portable diy in 12V. No reason other than more of a learning scenario for me. Had I known about stuff like this several years ago I would not have purchased all my Jackeries, EcoFlows, and Inergy Kodiak. Great video and thank for the information. I do like that distribution box you have.
There is a disconnect on your battery, you you have a disconnect after a disconnect. The point of the rack server and all in one you don't need the disconnects as they are already installed.
Great video information .I'm setting up a system for my New RV trailer. Do you do Solar advisements on a new Solar system.
I need this for my sump pump. Thank you very much for the video. I haven’t seen a video out yet by anyone that will show what size of system that is needed to run a house well pump system. Water softener and iron removal system the whole thing . Most well pumps I assume are 240 volts. Thanks again.
Inductive loads require special consideration due to the startup current requirements and reactive power. The battery bank itself would have no trouble with the pumps, it really comes down to the inverter. When dealing with AC motors you need to start considering LF (low frequency) inverters. Most all-in-one hybrid solar inverters are high frequency inverters.
For 240VAC loads you want to look at more proficient hybrid inverters such as the EG4 6000XP (which has split-phase output). That, however, is still a HF inverter so you end up either ganging two together, or you buy a discrete LF inverter specifically to handle the inductive loads and leave the HF inverter for everything else.
Examples of LF inverters would be something like a Schneider (for high quality). Also Victron (mid-market), and AIMS (mass market, not as high quality), and a number of others. I know I'm missing a bunch of good LF inverters in that list.
The amount of solar needed can rise quickly as the inverter size increases, due to the idle consumption and general power consumption of the system.
Thank you for this review, I just got the PowMr 3200W 24v and I believe this video should help me set it up easily without intimidation.
Hello. I just got the POW-4.2M-24V-N
I see you got the similar model. I have no idea how to program it. Sadly.
It keeps beeping twice every 3 seconds and the soler Panel icon is flashing. Not sure what that mean or what I could do. Any idea?
Thank you.
I watch the video on here. But he did not mention anything like that. Maybe you have an idea.
Thank you
Great Job! Very clear and concise explanation between the two systems. Up front cost for 48V systems can be a bit higher than 12V in regards to batteries and/or All-in-one units but the payoff in performance is there. I run in middle of the pack with a 24v system as my main BU pushing a Growatt 3K AIO and it meets my needs perfectly. Also run a 12V MPP 1K for smaller tasks (All pieced together over time). Will probably be switching over to a 48V as main in the future, just have to warrant the cost for the Wife. 😁 Great video-Have a great day! BTW, I really like that AC Distribution box, going to pick one of those up-Thanks for the link!
And not just performance... Consider wire size and cost and the difficulty of dealing with large wire sizes. If you need 200 amps sustained, you need 4/0 (0000) wiring. If that is on a 12v system, going to a 48v system means you only need 50 amps sustained, which is comfortable on 6ga and very conservative on 4ga.
Of course you should choose a 48 Volt system. Just NOT a short lived, low surge, high frequency inverter system. Low frequency transformer based inverter charger, make a far better choice.
I installed a 24v version from eco-worthy and I'm super happy with it
Hey how long did you have that inverter? Any issues?
Installed end of Nov...
Had 3 test runs without any issues
Installing my 24v eco worthy solar system this weekend. Hoping for the best
Have fun
What settings are you using on your PowMr for the battery charging? I have a 10Kw PowMr /51.2V lithium and once the battery reaches full charge, the charge voltage spike to like 59V and trips the inverter. Any help would be much appreciated. Great videos! Thanks!
Off grid 20+ years and my system is 12 volt. The reason is off gridders use a lot of 12 volt appliances like pumps, fridge/freezers, lights and cooking appliances. Those will run off direct DC with no inverter needed so no loss and they will run even if the batt voltage drops below the cut off point of the inverter. Those are survival systems we need to run all the time.
You can run 12 volt appliances off 48 volt with a drop down converter but then you are losing up to 15% efficiency and that is not good when you have a smaller system and off gridders are not connected to the grid to recharge.
What about the WIFI ? I see an antenna. I have the 24v version. Would you or anyone happen to know how to set it so the inverter automatically switches off after a certain amount of time like you mentioned? BTW, thanks for another excellently produced video.
What size braker/ fuse are u using or u recommended for 9 pannels rated at 305w voc 45.35 ..the braker between the solar panels and box
Nice demonstration Sir. Is this PowMr inverter very good? I want to order 4.5KVA 24v system. Kindly advice. Is it reliable?
so nice video !! could i know whether you have interested in testing our powerwin 12.8v 100ah lifepo4 battery ?
Hello does this Hybrid inverter push current back into the Grid?
The 12v system is still more practical than 24 or 48 volts.
If you want to install 12v devices like sockets, 12v heaters, 12v lights, 12v appliances, 12v inflator, 12v etc. you get the picture.
Besides the heavy cables. 12v is still the king.
Let me know when they start making 48 devices.
Cybertruck is supposed to be 48v platform. But Tesla ran into a snag.
No one makes 48v devices. Tesla was focused to convert 48v to 12v.
My question is did you separate the grounds in that distribution box?
Is your battery cutoff switch necessary when your battery has a switch? Or is there another reason you added it to your system?
Hello, what amp on or voltage is that DC disconnect breaker, please?
This is probably going to sound unintelligent, but, is there a higher voltage option? What's the feasibility? Asking from the perspective of preparing to buy land, homestead, and a shop with 3-phase power, including many "employees" aka, CNC, 3-d printing, laser cutting, etc.
How do u hook up a generator where i live u have to have that in winter
hey can you help i have powmr 3 phase 12kw model . i have wired it all profesionally payed electrician , today was first day when it was connected. i am getting around 700 volts from panels but it was cloudy day and amps were very low like 2 or 3 amps . is that normal ? if amps are that low but voltage is high is that normal for cloudy day ? and can you run anything on house with low amps like that or no ? i do have 5kwh battery hooked up to it as well.
I have the exact same setup, inverter and battery models. While rushing, I shorted the Positive from the Inverter to the Negative on the battery and think I messed up the battery. I only show 15 instead of 16 cells on the BMS. However, when I opened up the battery I only see what looks like 14 cells. Any chance you opened up the battery and can help me understand the count? Apoligize if this is not the correct way to communicate... Never really commented on TH-cam before.
can the batery b 24v n solar b 48v? or it has to b all 48v? does this hav the option to charge bateries thru the car alternator?
What is the idle consumption?
Hi David,
Good video as usual. I have a few questions, if I may. You have a circuit breaker/ disconnect going from the inverter to the battery. Is it necessary to have that with a circuit breaker already on the battery or is it just an added safeguard? Also, did you have to buy at least ten panels from Signature or did they just sell you four? They did have a special up until Valentine's day for free shipping. The reason I asked about the panels is because that inverter can handle about eight to ten of those panels. Maybe you have plans to add more later? Maybe you bought a bright mount that only holds four of those sized panels? Maybe I think too much and ask too many questions? LOL. Also, if you need more panels in the future, the Facebook market place is a good place to look if you have something big enough to haul them in, like a pickup. You can save on freight charges that way. I look forward to hearing more about this system and that 48v 100ah battery. BTW...just a few days ago a channel named"Beat the bush" did a complete tear down of that very battery. It has bolt on bus bars, not laser welded but I bet you already know that. I just want to thank you for all you do and look forward to your future solar adventures.
As always, much appreciated, Steve.
make sure you use dc isolator and brakers on dc side not ac also buy good brand
when you say " if you have a system over 2000 watts consider 48v" are you referring to the total watts produced in 24hrs? or are you referring to having an inverter that is larger than 2000 watts?
There are many versions of this inverter on the market.
What I couldn't find out is if it could bypass straight from the grid to the appliance. Dose this mean you don't actually need a battery?
I want to set this up for my 2kwh hottie heater and make it as cheap as possible.
My hot tub cost £1k a year to run and adding a 3kwh solar array will definitely take that price down.
In the uk I can build this for £700 including the pannals.
But if I can save money by not buying battery it would save me £1.3k.
Please advise me.
I like the way PowMr separated DC in/ out pv and AC in and out..I know you probably the only one using the system but it's best to put that ac input wire far from inverter output otherwise you might have a situation where someone plugs inverter input into inverter output..
Just keep in mind that there is usually no isolation between the PV and AC in/out of most of these things. That is to say that even without solar panels connected the PV input terminals must be considered to be live and dangerous. Most of the generic manuals for these types of all-in-ones do make indirect mention of it by way of telling you to not earth the wiring to the solar panels etc.
Another fine video, I do have a question about the DC breaker you installed between the All-in-one and the battery. That particular battery has one built in, so is there another reason to add the second one?
I've done the same with my 24v system
I'd rather stop potential surges/shorts BEFORE it hits my components
Can you please provide me the link for the panels please!!!
Great video, not sure how I missed it when it was posted. I had a question about the 48v setup when its in off grid mode, so just charging the battery and supplying power when needed. If the solar panels are still producing power and the battery is full and no load on the system does the inverter/charger just stop accepting solar input? as in it'll auto cut off drawing power from the solar? Cheers.
batteries are getting chesper you can get 15kw wall mounted battery for $3000 a lot off off grid use 30 kw or they use rack batterie 5kw were coming down to $1000 each prices went up so you beed 6 the good thing about wall mount you use less wiring
I keep hearing about the high cost of the cables for a 12volt system but quite often you can find booster cables heavy duty one's at garage sales and cruise the back alley and I find them all the time clamp not making connection and out to the garbage it goes wires are okay 12 foot of copper wire x 2 no cost garage sales rarely more than 10dollars I used one to hook up my 1750 watt inverter all I had to do was was cut off the clamps and put 2 battery post ends on on each cable to hook up 2 cat batteries and hooked it up to the inverter with a fuse worked great until I found out that I needed to get a pure sine wave inverter
This is exactly what I do ,cheap battery cables at garage sales.
Nice video and setup. Btw any idea were i can find that distribution box with the 4 outlets but then for 220 volts??
They have a version with a 240V outlet on it, in addition to the 120V outlets. But if you're talking about the whole thing in 220V 50Hz standard, I'm not finding anything. You might try AliExpress or Alibaba. This particular unit brand is: JINDOUZI
@@ReeWrayOutdoors Same here. I looked up several brands but nothing that looks like yours maybe i can find it with the name you just gave me .Thanks for the help and information.
Great info. Could you do a quick video on how you would incorporate that 48v set up into an RV? Interested in where you would incorporate the 12v loads including a step down from 48 to 12. I keep thinking I have this all figured out, but I believe the theory is where I am getting tripped up. I can't seem to wrap my mind around having multiple power sources coming into a single busbar (which it appears everyone does in the video setups I see). Thanks
Basically you make the 48V system the "home" battery. The biggest, baddest, beefiest energy storage in the RV is the 48V system. That handles all the major loads. All the solar, charging, and other power sources go into the 48V system. It is the hub for everything big and also runs all the AC inverters.
The biggest decision you have to make (see below, the third section) is how to deal with the vehicle alternator. I'm saving that for last.
--
An RV will still have a lot of DC 12V loads regardless... the stabilizers, pop-outs, often the lighting and many other small loads are typically 12VDC. To handle these loads you first calculate just how much power and energy storage you need and you size a 12.8V LiFePO4 battery to that need. For example, a 100Ah 12.8V LiFePO4 battery can push 1200W continuously and typically surge to 2400W or higher.
Tying them together, you simply have a 48V-to-12V DC-to-DC charger (Victron makes one, for example) to keep the 12V battery fully charged. This is called down-buffering. It does not have to be a beefy charger, it can trickle-charge the 12V battery. It just needs to produce a tad more energy than your typical "continuous" consumption (aka lighting) would eat. So usually 8-12A is plenty.
Some people use smaller 48-to-12V DC-to-DC converters without a buffer battery, but I strongly recommend using a proper 48-to-12 DC-to-DC charger with a "small" buffer battery (just big enough to handle the necessary 12V power delivery and surges).
--
The major decision you have to make is how to integrate the vehicle alternator and the starter battery.
My recommendation: Keep things as simple as possible when it comes to the starter battery and vehicle alternator, meaning don't try to charge the 48V home bank from the alternator (if you have only one alternator). If you have room for a second alternator, then consider upgrading it to 48V and charging the home bank from the second alternator.
There are numerous other choices here as well. Some people don't even bother having the alternator charge the home bank, instead relying only on their solar, external power, and generator for that.
-Matt
You cannot combine 48v and 12v on the same positive bus. They can share the negative or "common" bus.
@@junkerzn7312 I'd prefer to use a larger (40a is typically plenty) 48v to 12v buck converter and skip the additional 12v house battery.
But actually, in an RV I'd seriously consider 24v instead of 48v. Usually the inverter is the big load and 24v is reasonable for RV inverter sizes even when powering dual air conditioners. 24v might be an advantage because many things are available in 24v or even flex 12v/24v because many OTR trucks use 24v.
@@Sylvan_dB There are good arguments that can be made. I would say, though, that most of the practical 12V and 24V solutions revolve around retrofits and not so much complete refits / new-fits, or new builds. If one has a lot of legacy 12V or 24V gear, upgrading to 48V might not be financially feasible.
For dc-to-dc... well, for low power solutions a direct DC-to-DC is fine. A very cheap solution that will work well. But consider what it would take to support, say, a 200A startup surge on a 12V system? Or even just a 70A surge (the typical startup surge for leveling motors).
At that point the down-buffer solution is not only less expensive, it is also far more robust and won't even break a sweat. A tiny little 100Ah 12.8V LiFePO4 satellite battery doesn't even get warm at 50A, can push 100A continuously, and can handle several hundred amps of startup surge.
There are many other advantages too. The loads on the down-buffered battery are independent of the main system, for example.
--
The main issue these days is that people want all the comforts of home in their RV, and to not have to worry about tripping limits. It is incredibly easy to blow past 3kW, even past 5kW, just with a fully outfitted kitchen (induction burner, microwave, toaster-oven, tea kettle).
Add everything else in and the max power can really get up there. Macerating toilet, hot water, motorized pop-outs, leveling, mini-splits or A/C (x 2), and so on and so forth. Plus people only want to have to run their generator once a day for maybe 1-2 hours at the most in worst-case conditions. And put incredible amounts of solar on the roof (some people even have rails for pulling out even more solar when parked). 2kW is not uncommon on a big RV. Plus people want buddy connectors, beefy external hookups. The list is endless.
Not everyone wants all of this, for certain, but most people want to be able to have the flexibility to expand into it over time. 24V can get strained pretty quickly.
I will also note that cab-to-trailer power interconnects are often being omitted now. People are willing to forego alternator charging entirely in favor of just having solar, generator, and external hookups.

Ok guys I need some help with this thing if anybody can help. I have this thing hooked up, exact, same as this guy in a video here. But it’s wanting to stay in hybrid motor or something when I cut the DC power breaker off it will not pull power from my Solar panels or batteries can anybody tell me why why does brake have to be on for the DC power to go into it for it to push Power into my sub panel box ??
OK, let's think about this 12 v takes less panels to charge batteries you need over48 v panel push the power.
Let's go to the medium and go 24 V. It seems to work really good for me. in some areas.low frequency lasts longer for long-term
Question-have you set up your new Hyundi panels and how do you like them?
I'm consistently using 4 of them for the past couple of months. Very happy with them. I do intend to do a video to investigate how much (if any ) difference I can get out of the 'bi-facial' cells. Just waiting on more consistent sun and temp conditions. If I had to find SOMETHING to complain about...I'd say the MC4 connectors on those are a BEAR to disconnect once you connect them. Not going to be an issue for most people, but for me (since I change things up regularly for testing purposes), they're super annoying. Had to modify an old 2-prong extension cord plug to use as disconnect tool since the 'normal' MC4 tools don't fit the connector style Hyundai is using. :P
Is it possible to use this POWMr inverter in an off grid setup ? Would any Ac mains supply ?
Yes AC mains connection is optional.
what kinda specs should the solar panels be for a 48 v system with this powmr inverter ? like how many watts ? and can i link two or more 24 v batteries instead of one big one like the one in ure video ?
Yeah, you can definitely connect 2 24V batteries in series to get a 48V battery bank. Regarding solar, you can use whatever panels you want, provided that you don't exceed a combined 450V input from those panels, or you risk damaging the charge controller. The max solar power output is 5500W..but you can overpanel by putting MORE solar power in than that if you stay under 450V. The amp input cap is 22A, so be aware that if you configure a panel array that is higher than 22A, the charge controller will still cap the current at 22A and you'll be 'wasting' input potential.
I have the Victron Multiplus 12v 3000 120. It's one of thier inverter\charger unit. I got it wired up in my RV. I have 30a shore power and my solar system.. I wish the programming for it was designed better like this PowMr. There's only one option in the software to "limit internal charger to prioritze other engergy sources". It doesn't seem to work. Just this setting might be enough to buy one of these.
on the other hand, despite the functional limitations, Victron DOES use extremely high-quality components, which is why they also typically cost 2-3x more.
How does this compare to the Sun Gold Power unit? This one is a little cheaper for 5000W.
Their functionality is pretty much identical, except for the 48V system voltage, 5000W inverter and (I think) larger solar input capacity. The user-interface itself and general construction seem to me to be virtually the same as the SunGoldPower. I wouldn't be surprised if these are built by the same people.
I keep seeing everyone making videos about 12v systems compared to 48v systems, why is nobody showing 24v systems? Cause all that garbage of reaching over 2000watts 48 is better is nonsense when using 24v systems and is easier to maintain in regards to pricing when compared to 48
Usually the point at which costs start to escalate is over 100A. Once you go over that the cost of wiring and OCP starts to become expensive, at least for genuine stuff you can rely on. 100A at 24V is around 2.5kW (voltage of the battery is > 24v for a lot of the time). At 150A it's seriously time to start thinking 48V to halve it.

@@retrozmachine1189 I have 2 systems, 1 is 48volts @ 20kw with lithium batteries, 4 batteries 5k each, and I have a 24v system which I built at my mom's house, 24volts 60kw, lithium, the 34v system runs everything, water pump, lights, TV, 2 deep freeze and a 2 door standing fridge, it does everything the 48 does with ease
Yes, 48 volts is the best way to go.... ALL THE TIME
I beg to differ, I run a small system using a schneider 24v, it runs everything, been doing it over 10yrs now with no issues, water pumps, jack hammer, saws, drills, TV, fridge, computers, EVERYTHING, the only thing people seem to miss is the battery draw, ya cant use a limited amount of batteries or the inverter will struggle, I have 60kw of lithium @ 24v, the system runs flawlessly
I tried the 48 volt system and the 36 volt system the problem was i didn't have enough solar to make the system run smooth. A 12 volt system like you said its prob. good for 2000 watts or less. I have about 400 watts in solar panels on a 12 volt system and it runs perfectly. I'm going to switch over to a 24 volt system with no solar connected to run my box Freezer at night. I'm not sure how it will run until I see the final results. Do you know if a 24 volts system would be a lot more efficient than a 12 volt?
There's definitely a measurable difference in battery capacity utilization efficiency, even with 24V. I actually demonstrated this in my parallel vs series video awhile back if you want to see the difference: th-cam.com/video/EDLxolJ0QxI/w-d-xo.htmlsi=xzTnNJBXsoPDuM4o
@@ReeWrayOutdoors Awesome thanks
The main requirement for solar on a 48V system is that the operating voltage of the solar string should generally be north of 61V (and VOC 70V+) for the charge controller to work properly. That's it. 3 x 100W panels will usually do the job. Read the label on the panel for V(operating) and V(open-circuit) to figure out how many panels in series you need, and also make sure the the sum of the VOCs does not exceed the voltage limit of the charge controller.
Other than making sure requirements are met, the solar will put just as much energy into a 48V system daily as it will into lower voltage systems. More, in fact, because line losses are lower at higher voltages. The solar has to be configured properly and that is what trips some people up.
2 x Residential panels in series, or 3 x 100W (or 200W) panels in series, or 4 x 75W panels, or 4 x 50W panels, or 4 x 25W panels... in series. That's usually the minimum configuration for solar on a 48V system.
If variable shading is an issue adding an additional panel in series helps a lot, but again you have to make sure the worst-case VOC is under the charge controller's max input voltage. Well, de-rate by 20% or so just to be safe.
A Victron SmartSolar 150/35 is an excellent fit for a 48V system. A Victron 100/20 works with 3 x 100W/200W series configurations but the voltage range is pretty tight. You need 61V (operating) but a Victron 100/20 can only handle up to 100V (open-circuit).. which is really more like 80V or 85V if you push it to give yourself margin for bright/cold conditions.

I get confused when they say AC charging as 60A or 80A,,new ones go up to 120A., Is this DC, I would assume its DC for batteries, perhaps unfortunate choice of words to call it a AC charger...My shed is MAX 30 A AC so I do not want to pull too much.. Thanks if you can confirm its DC.
Yeah, it's an 'AC' Charger because it's taking AC grid power and converting it to DC to charge the battery. And so when you see a battery charger with a rated charge current of say 30A, it's referring to the DC current going to the battery. So a 30A charger for a 48V battery system will be pushing something like 1500W...but on the AC side, divide that 1500W by 120V and you're only talking

A "battery array" ... is called a battery. Inside that 12v battery is an array of 4 cells in series. Each cell might be an array of many cells in parallel. It comes from military, where a battery might be one or more units, and if you add more units to it, it is still a battery.
For batteries it's called a battery bank, for Solar panels it's called a panel array
What about low voltage \ LED lights

That would be true IF I left the original battery in...but as I state in the video, I removed that...so it actually does not run without being plugged in
@@ReeWrayOutdoors Ok, I guess I missed that part where you said the laptop had no battery.
Why is there so much talk and not enough wiring work . Also why are there many explaining on 12vts and 48 vts .. im confused 😮😢also the breakers grom battery to inverter in not necessary. Maybe the solar panel breaker or disconnect switch it just looks good but not necessarily needed. The inverter already acts as a disconnect. To much yeahra yeahra.
Why is there nobody on TH-cam comparing 24v and 48v inverter system. Why is everyone doing 12v and 48v. It's terribly annoying.
Because if you're gonna step up. Doesn't make as much sense to moving from 12 to 24. It's just giving yourself a broader buffer for capacity
48v is still 2x more efficient. Don't get me wrong I love playing with 24v
check will prouse
12volt has the benefits of powering some comon dc loads. 48v is the most logical next step. Even though I have just purchased a 24v multiplus lol. Well the reason is I have already 8, 305ah cells running a 12v system. I can use my existing 12/24v charge controllers ect.... and well I'm doing something odd and feeding two 48v 130ah batteries to feed into my 12v system when required(via charge controller).... a hybrid 48/12(soon to be 24v)system haha
Don’t go 12v. Don’t waste your time. Always do at least 48v and it’s because you will not be happy with just a couple 12v batteries and a little inverter. What’s gonna happen is you’re gonna buy a little inverter and a couple 12v batteries and then 5 months down the road you’re gonna get another battery and parallel it into the system and then get a bigger inverter and then you gonna get some solar panels and a charge controller and then 3 months after that you’re gonna get more solar panels and then $9,000.00 into the 12v system you’re gonna say “FUCK!!!! I don’t want 4 solar charge controllers and all these giant cables and shit FUCK!! I SHOULDA WENT 48V and I’d only need one big ass all in 1 inverter charge controller charger”
Don’t do it. Just stfu and go 48v.
'Promosm' 😅
I can't absorve all your knowledge in a 30 min video... how about if I send you details of my system and needs, and you tell me what I'llneed to get it working?...
Up to 2000 watts?😂😂
I guess i've been doing it wrong all this time....
I have
10 - 12v 100ah lithium batteries...
3 - 2000 watt inverters
2 - 1000 watt inverters ..
My system has been running for 5 years.
Please stop putting out false information like this
I'd love to know what you think said that was false. I'm happy to hear you out.
@ReeWrayOutdoors 12v battery system can handle way more than 2000 watts.
It may not be as cost efficient....
But someone on a budget can spend fifty for sixty bucks a week easier than spending fifteen hundred or two thousand dollars.
12 V systems Are cost efficient for those who are living from paycheck to paycheck.
@@vinny143 Within the first 30 seconds of the video, he states over 2000 Watts "48 Volt might be something you want to consider" and then proceeds to give examples why you "MIGHT" want to consider them. Everyone's needs and circumstances are different depending on budget. So you may need to piece something together over time like it sounds like you are explaining in your example, he is also providing another option, and never said that 12V can only handle 2000 Watts.
@@jayb3518 " They are good for about two thousand watts"
@@jayb3518 It's a great video and I enjoyed it....
You’re laptop has it’s own battery so no it wouldn’t have shown a disruption.
As I said and demonstrated in the video, that battery is removed so any significant disruption in power (approx > 50ms) will cause the laptop to shutdown.
