My good man I listen and hang on every technical aspect and word that you bring up. Your opinion is as valuable to me as an instructor at a Harvard electrical engineering College
Well if that impressed you I sure as hell don't want to send my kids to that school where'd you say it was located want to be sure to put that on the list not to send anybody to and to advise others not to go there for electrical engineering as you should have had input instead of being overwhelmed this tells me a lot about your class
Thank you for sacrificing a busbar for we could see the make up and for testing their capacity.
As usual, well informed video. When those fans ramped up, sounded like that thing was ready for flight.
Yeah, I feel bad for that busbar too. About half a minute after that all I could think of was "what a good quality busbar, it's pure copper and costs a lot. How many of those busbars do the distributors and retailers cut when they check their product quality, how much natural resources do we waste to maintain trust of the market". I hope they are at least recycled.
Another great video, very informative
Great video. Thanks for sharing.
I love this inverter it’s heavy duty for sure and is completely reliable so far. As far as the charge controller there is no way to know what it is doing because there is no separate display for its so I don’t use it. The fact that it is always pulling 230 watts is a negative in some regards however if you have a large array I’m sure it won’t matter.
After watching your video I’m thinking maybe rewiring the fan with a separate switch maybe the best thing. Great video thanks.
Fantastic video as always! Thermal camera helps with the storytelling a lot as well.
I purchased a 4Kw unit like this and also have issues with the fan always on when in inverter mode and the On position. As mine is used in a travel trailer, I normally use the Standby position. You may want to test the battery priority vs. AC input priority DIP switch to see if it makes a difference on the fan runtime.
Oh man! I was drooling over your battery bank.
AWESOME job! Very informative!!!
I finally load tested my son gold 18 KW inverter. I turned on every Appliance in the house. All four electric range burners, the oven on preheat, the electric dryer, the air conditioning, and just about everything else computers lights etc. The total load came to a little over 16 or 17 KW and the DC draw on the 51.2 volt battery was about 370 ampers. The inverter just chugged along like nothing was any different than the usual. Absolutely amazing piece of hardware.
How much was the A.C. ampacity (amp draw) with all that on. I was told that it could put out 95-100amps indefinately. Is that True? Hope So.
@@user-tm8ky7ok7e The AC load ampacity is closer to 83 A continuous. With everything running simultaneously, the load % reading was around 93%.
Still happy with it?
@@stiffmeister0hYeah Going on 3 years and it just does yeoman service. No bells and whistles, just steady electricity. Our only challenge is the rainy conditions we're having this year. Staying on battery power is challenging when your PV input is low due to heavy rain.
Very Helpful Review!
The constantly spinning fan while cold,
high idle power utilization is troubling, and
fairly low panel voltage are unfortunate.
I have the sungold 6000 split phase and love its performance and everything about it. I'll be upgrading to a larger model soon!
Diane, I am thinking of buying that model. Is the fan loud? I hate noise. It looks like a great model with the ability to run from solar PV direct to load (batteryless).
Did you have any problems with it. I am having an issue with mine recognizing a load on one leg. Feeds power but doesn't recognize load
Beware of Sungoldpower- they do not honor their warranty- bad business
Great video...Very informative and nicely explained.. 👍 Love from India...
Looks like a decent inverter. Only other drawback I thought was the single 40a mppt charge controller. I would like to see at least an 80a or dual 60a. Great review!
I'm surprised it's only rated for 40A considering it looks near identical to the PCM60X and that's rated for 60A. What does your Growatt have? 80A?
@@LithiumSolar got the growatt 12k dvm mpv as a backup unit.
It's got 2-60 amp mppt at 250v input with 7000watts max array size. I think average Joe got the 150v input unit, not sure if it's dual 60 amp mppt or not.
Yeah, even the newest version Max's out PV input at 145 volts and only 4000 watts. I mean All the larger 'all in one' inverters (the reputable ones, I haven't checked all the Amazon junk) have either 250 VDC to 500VDC and usually max out in the 6000 to 8000 range (some more) and most half that rating and larger have a dual MPPT charger system. I am not sure what that unit costs but it is lacking in a few areas. If it is under 1800-1900 bucks, I would say that the short comings might be worth working around, if you're on a tight budget.
Ya'll Take Care and be safe, John
Thanks for this video.
impressionnant 12KW ! Merci pour cette vidéo et ce test ! ce serais bien de tester la partie PV MPPT. je suis très curieux de cette présence de sortie DC ? je me questionne sur la tension DC de sortie...
Great vid...video... looking to buy 2...
Do you know if they can be hooked in parallel??
Thanks for another great video.
Instead of your schmancy wirewound 1ohm 100watt resistor you could use a rubber fuse/current limiter, otherwise known as an evacuated, radiant tungsten resistor, otherwise known as an incandescent light bulb. If the device you have seriesed with the lamp tries to draw more than about 100 watts, the lamp comes on full brightness but likely nothing blows up if there is a short, the current is limited to 100 watts. Works great as an inrush limiter. You can also get them with a 60 or 40 watt limit, and they are also available in DC versions with 12v and 5v being fairly easy to find. I used to know the part number for the 12v was it a 5015? With a little bit of practice you can guess pretty close how much inrush current and the running current by how the light looks when you throw the switch. Really handy little device. It is handy to wire one up in a jbox with a 3-way switch, one position your lamp is in series the other position straight through ac. In addition to the visual indication you get, that 100 watt bulb is better than a resistor for what you are doing here because the resistance of the lamp changes with temperature, simple soft start of sorts. It could be that some inverters would recognise a fault on the AC line if you tried to run it with that lamp in series with the ac input so be aware of that.
So can you Add controller s while using additional controller's?
Great Video. what was the display you used to show the current/watts/voltage? also what batteries did you use to build that? I am thinking of building a 48V bank vs purchase. a 100aH 48V is about 1400-1800 USD.
Nice video, what’s the best home inverter that you have tested. We have a 200A panel for our house. I’m considering going solar with a 12-15KW battery. Thanks ahead.
80 amps on the AC breaker with agw#12 seems a little light but it did the trick and didn't show up on the heat gauge. Thanks again. Oh if you get a chance to measure the surge on a lra device I hope you show us.
Do you need a specific kind of bms for your batteries configuration or will a normal 16s 200ah or 300ah bms still work perfectly
I find the build quality very good, idle consumption could obviously be better. The MPPT controller is a real weak point, since 145v input limit is very limiting if you need an inverter that large. I personally would prefer lower idle consumption and a 250v MPPT. But yes, that is capable of running an entire house. Good review, BTW. Those busbars are better than I expected.
Mine input for panels will be 300 V so I would be out.
UL or ETL RATING? Grid interactive?
No UL or ETL ratings on this unit.
@@LithiumSolar - “No UL or ETL”
Does that make it illegal to run in the US,
in a grid tie?
@@DavidHalko This is NOT a grid-tie inverter.
What the IR camera did you use? I'm looking for one.
Thank you for this video!
It's a "FLIR One" that plugs in to my phone. I wouldn't necessarily recommend it though. It's kindof slow and has lower resolution than some others I've seen people using.
this is an awesome inverter... it powers my entire home including ac's, 110v heaters in winter, power tools, etc... I was skeptical but I'm very happy to have it now. The charge controller is very under powered but you can disable it and run as many charge controllers/solar arrays to your battery banks. I currently have 22k watts of solar coming in through 4 charge controllers to power my 6 100ah 48volt lifp4 batteries. This inverter has never faulted or shut down even though my hot water heater, dish washer, washer and dryer, etc all run on it. 5 stars from me. trust me, I've had my share of crap products
Question for you; Why would you disable it's charge controller? Couldn't you just add other controller's to the bank?? Sincerely KC. I'll check back in a day or so ???
It’s only a 100 volt charger on the older model that I have. You could absolutely use it but my strings are much larger than 100 volt-
@@jasonhensley947 Thanks Jason, May I bother you a little further??? I just purchased this 12000. Dual . I have 7.5 thousand watts. 12 100 ah Battery bank. So my ? Is can I connect some to it and still leave the others connected to the battery Bank??? Thank you for your time.
@@TheVoiceofKevinC If i am understanding correctly, you want to can you use multiple chargers as well as the charge controller on the inverter? If that is the case, then yes- by all means. Example: I use my old Growatt 5k's as charge controllers and have around 500volts coming into the external bus bar from each. I also use 2 additional charge controllers connected to that external bus bar. That is routed to the battery bank bus bar so that all charging is done simultaneously. I even have a "chargeverter" from EG4 connected to that bus bar so I can charge from generator and/or grid if needed. You can multiple charging sources to the battery bank. This then powers the 48v inverter. So in essence, the inverter works off of the battery to create the AC power source seperately from the DC power bank/solar. Hopefully I understood your question.
👍👍👍🤔😎🤠💯Thanks Jason. & Wow you have some serious power going on😱.. I really appreciate the feedback.... Again Thanks very much
Could You measure it's efficiency at different output power?
What is the function of the two large copper coils in the BMS,. as you explained the other components. All the footage I have studied does not explain what they do. My days of applied elec. at school all I remember of similar coils were RF chockes. Radio frequency.
Great video...lots of info...would have liked to seen power quality testing...Many "pure sine wave" inverters really aren't that great.
I dont like when they make a set charge voltage. I prefer a fully settable voltage output. Id stick with Magnum or Outback. Great video
Nice man. Like you say that idle load is a bit much. Thanks for sharing. God Bless.
Do you think you could review the 12k ETL listed version of this inverter?
So is the solar charge input 60a like the
Pcm?
Question Does the power transistors probibly MOS FETS have numbers on them ?
Seems like it is very similar to the Growatt SPF 12000T DVM 12kw 150vdc. Do you think the dual MPPTs can be over paneled as long as one doesn't exceed VOC? By how much?
Great video as usual. One thing I see is a lack of parallel function. I would prefer multiple smaller parallel hybrid inverters rather than one large inverter. I see that Growatt announced in September (but I do not think yet shipping) a 2nd Gen version of their equivalent of this inverter. It looks like the Growatt SPF 3000T HVM-G2 will start with a capacity lower than their current range. Parallel inverters mean less total failure risk, each one is lighter to handle and needs smaller cables. They too are low frequency inverters, but the 3000 model can handle PV up to 200VDC operating voltage and 80A, so if you have more than one array, multiple inverters give you a lot of flexibility. The AC charger is also relatively (compared to the inverter capacity) large, at 40A. With multiple inverters, you could have multiple battery banks. Growatt have not said whether this new range will use standard laminated transformer (such as the ones you see in this SungoldPower inverter), or whether they will use a toroidal transformer (better, more efficient). But, given that Growatt claim their new product will be 95% peak efficiency, which is much higher than normal (1st gen version is 85% in the smaller versions), it is possible they they may be using toroidal transformers. One can but hope. For now, they are clearly selling off their stock of the 4000-12000 1st gen range (which is their direct equivalent of this Sungoldpower inverter). The 12000 is down to around $2300 including shipping! You also do not mention Wifi (app) control, which the Growatt has an option for.
sungold 6000's are parallel-able and half the price.
@@DieselRamcharger Yes, and I have both on 2 separate applications and the 12k will, without a doubt, start and run much bigger inductive loads without faulting. I have had as many as 4 6k's in parallel and still will fault on heavy start ups.
Love the review. My 12kw sungold just arrived. One thing I noticed, I'm fairly certain the ground in the terminal block is for the AC input, not the AC output. You'll want to use the grounding terminal (that separate terminal) to ground the AC output.
You should see continuity between the ground points anyway. You don't want multiple grounds with voltage potential between them.
@@LithiumSolar good point. Thanks for the reply! I suppose I was thinking the flow of current needs to go in the right direction, but the direction it flows through the device doesn't matter. It will end up going to your home ground in any case.
I noticed at one point you mentioned that the PV input is to accept a connection from an MPPT or other charge controller. It's my understanding this unit has the MPPT charge controller built in....so that connection would be for the PV's directly....or am I incorrect in this assumption? The manufacturer mentions the MPPT controller being onboard as well. Not sure what would occur if you connected 2 MPPT controllers in series.
Hi, what does Uid and noa stand for on display under ac input on sungold 8kv inverter ?
looks like a damn good inverter. A bit pricey but worth it I'm sure
Bro, you rock!!!💪🏽🙏🏽👍🏽
Massive great review
Does this unit have a generator power assist feature, where can pass through power from a backup generator and add to that power for motor startup surges if needed?
No, it does not. What you're describing kindof sounds like a grid-tie or hybrid setup. This is strictly off-grid with no parallel or stacking capability.
How is the internal transformer wired when the inverter is in grid pass thru mode?
Can we see the inverter output waveform when it is loaded at 12KW
I've got two identical AIMS 48V 10kW inverter chargers which are almost identical to this. The controllers failed in both (the board on top with the relays which handles the shore power to battery switchover). One unit's fans are always on, the other always off at idle - even after changing both boards! So perhaps you're seeing a similar issue - maybe a sensor problem.
How are you getting the readouts on a tablet?
Great video
Great info.. how did you get the readings to pop up on your tablet? Is it an app or something
I have a whole video on that exact topic here :) th-cam.com/video/wKTXJidnfl4/w-d-xo.html
Very nice inverter
How did you crimp the main positive and negative cables of your battery? I had a a heat problems with my crimps until I purchased a high quality hydraulic crimper that produces gas proof crimps. Which means that the individual copper wires in the cable are compressed so much that they meld into a solid piece of copper.
I used a high quality hydraulic crimper.
Did I miss it,how much is the cost? Thank for the good review.
what tester do you use?
It looks just like my Growatt 12kw and my 6kw looks the same, just a smaller core on the 6kw also built the same as well. Odd. But the Growatts do have a clear plastic for air flow control which is nice. Over all that looks like a good build.
I compared the internals to Average Joe's 12kW Growatt video and agree very similar, with the exception of different MPPT charger boards.
Yes I have the lf 6k growatt also and the 12k on the way and the placement and transformer both look very similar.
Good old Fluke 73, good multimeter tested a lot of them in my time as a calibration Technician. What was the temperature in your house to compare please mate.
The garage was cold, around 55F if I had to guess. I'd love to get my Fluke calibrated if I can ever find somewhere/someone to do it!
Do you know if two or more of these can be wired in parallel? I went to the web page and read the users manual and I could not find any information on this topic. Thanks.
No, these do not support wiring multiples in parallel.
I have also one of those and i can not use otherwise then charge my car...it just have to big self consumption ...and batterys are emptied for nothing...i made some modifications about the fans.... tep. controled 12v 4wire Nidec 120mm fans with b.b. that give me 0,5A less self consupt...
Now is on only on demand....
Main inverters are two MPPsolar 5048 Mg
Nice
Great video thanks for sharing. Very informative. I’m curious how many watts of power do you have coming off your solar panels?
I've got around 10kW right now
Thanks for the reply that is very helpful. What kind of results do you get as far as around the clock power with that system? Does it run all night long and then able to charge up during the day and then do it again the next night?
And why did you choose those batteries on this video compared to other ones?
I seen a video of this type inverters and the guy showed that using some kind of snap on ferrite choke on the wires going to the transformer significantly lowered the idle consumption. It was a video from a guy in a far off country in the jungle I believe
Oh, if you happen to come across that video again - please share!
Waw, impressive !
Can a 10k generator pass through along with my 10k solar to give me 20k out of total ac, or is it just one or the other. Will I run into sign wave problems on the output.
Great video but Davidpoz posted a video on the SolArk having only 1 leg go over and shutting off. I am curious if this unit does the same.
This inverter can hold 125% of the rated output for 15 minutes before it shuts down.
@@LithiumSolar that is great. The SolArk refused to do that on one leg. Is that 125% based on one leg or overall. I plan on expanding a broader. The heat lamp is 110v so 1 leg will be used. If I turn on a saw, will I push a single leg too far and it shut down or will the unit offset the heat on the one leg and continue at 120% of rated for that leg?
How were you monitoring your battery bank on the tablet? Is that a feature of the inverter?
no, he have a device there that have bluethooth.
Ideal!
very good
I don't really get the complaints about the PV input or idle power consumption. I'm running the 18kw inverter (over 200 lbs!) and using two midnite classics for the PV input. These powerful inverters are reliable and powerful. I currently have 10,000 watts PV input and having one panel (300 watts) dedicated to idle consumption is not a problem.
It's a concern for me as my panels face mostly west and I don't have a lot of space to add more. Maybe if you have a huge area and can simply buy another few kW of panels - sure. This is especially problematic in December-Feburary timeframe as once they get covered in snow, now there's pretty much zero power output unless you go scraping it off.
@@LithiumSolar These 12kw to 18kw inverters are obviously designed to run a small cabin or entire house. I have 24 - 440 watt panels now on a ground array facing south. Dedicating one for idle power seems reasonable. From other videos, it seems like all of the powerful offgrid low-frequency inverters have 200+ watts idle usage. A Sol-Ark is way too expensive IMHO and I'm not sure it can handle the surge current ? Do you have a video for connecting 3 sets of 16S LifePO4 batteries ? Great work, love your videos !
I have some 48 Volt 4 kw units like that one and the fans on the transfomrer end run all the time. They are 240 volt fans not 12 or 24 volt. The small fan that moves air to over the FETS is 12 or 24 volt PWM so it comes on when heavy load is put on the unit.
Now you may be able to isntall a realy that can be triggered off the FET fan coming on but it may not like the PWM signals.
Great video . Could I know any lithium battery can communicate with this inverter ? Need communication protocol ?
No, this inverter does not have any battery or BMS communication capabilities.
@@LithiumSolar thank you so much ! That means we can use this inverter and connect to any lithium battery or lead acid battery , correct ?
Good review and partial testing but low PV maximum input voltage and inability to parallel are deal breakers for off grid use. Undoubtedly reason for sale. We'll see what new models have to offer.
Sungold sells an 18K inverter for $4000. And it handles 3X surges in power which the low cost inverters can't handle. I bought Midnite Classic charge controllers to supplement this inverter. It's the most reliable system available for a reasonable cost.
Do you know the awg size for the AC input for the 12000w version? Manual says 10-5awg, just wanted to make sure it can accept 5/6awg.
Yes, I can confirm it does accept 6 AWG THHN. I don't have any 5 AWG to test with (not sure that even exists).
@@LithiumSolar thank you. I’ve never seen 5 either, just making sure. Thank you!
I'm struggling to piece together a 19V (19.5V rating per the power brick) DC UPS for my Internet router. I'm also hoping for 12V DC out as well if possible. Maybe something I can fit in an Ammo Can (or similar size)? One additional requirement: I want to charge and run my device at the same time so there no switching cables if the power goes out. Any ideas? Thanks!
Best plan for 19.5V output is an inverter and the wall wart… but a variable boost controller should work. I have one that can set output voltage infinitely adjustable from 10 to 60V from a 12V battery. Amazon has them.
@@SuperVstech Thanks for the reply! Which type of battery should I use? How do I handle the switch over from live DC to battery?
Holy biscuits! 12k watts! Congrats
So this system bypasses its inverter when the 240vac input is avalible and goes straight to its 240vac supply? Genrally when a transfer like that is made a big meaty contactor is used to handle the arc and amperage.
I am about to buy one for a whole home backup but i just want to make sure im clear of its theory of operation. I would love to see a video of this inverter switching from on grid to off grid and back again.
I'm not sure of the specifics regarding how the built-in transfer switch works unfortunately.
Hi, is it possible to connect inverters in either series or parallel to meet a whole house total power requirement as opposed to connecting individual/ group of equipment to individual inverters. I'd really appreciate your response, thanks.
No. This inverter cannot be paralleled, seriesed, stacked, or otherwise connected to another inverter unfortunately.
@@LithiumSolar Ok, thanks. Are there any that can be used in series/parallel though.
Are these inverters stackable? I would need 2 x 18 000 watts or 3 x 12 000 watts.
No, these inverters are NOT stackable.
The only shortcoming I see here is that there is no RFI medication effort. They should have at least several ferret chokes on the wiring coming off of the secondary of the Transformer and possibly some on the wiring going to the battery side. I have the 6000 watt sungoldpower inverter and it makes a tremendous amount of radio frequency noise that obliterated the I am broadcast band and the HF ham radio bands. I have the 18,000 W version of this inverter on order since last month and I am awaiting shipment.
Got any more videos on this unit ? Just wanted to know how it was over time of its usage? Have any issues?
No, I haven't used it much. It uses way too much power sitting idle for any practical use here.
@@LithiumSolar I just want something I can flip on when needing 220 stove water heater air compressor. 220 stuff mainly? Got my 110 covered. Got 3 separate units. 1 small porch unit for charging battery for drills what nots.
I dont get it? so u run 12000W from 2 or 3 #12 wire and terminal blocks? You make your own outlet strip? thats like 100Amps running through 12awg. I think its only rated for 20 or 30amps max.
Can someone explain please.
Thanks
The wiring inside the inverter is considered "chassis wiring" which has a whole different set of rules regarding max amps compared to NEC rules (which seems like what you're thinking of). Also, it's a max of 12000W / 240V = 50A (not 100A).
So cute 👍🏻👍🏻 🇮🇳 || Kuki 14|01|2022
The idle being at 185Watts, is that at 48 volts or 120 volts?
It was measured on the DC side. The AC input is not connected.
What is the cable specification for the two 120AC splits and ground? The diameter for the three screw crimps seem to be too tight even for 2 AWG wires. I haven't purchase the cables yet because even 2 AWG available in the US shows that the copper would not fit in the hole.
I'm not sure specifically; however, I can tell you that you will not fit #2 in there. I used #6 and I think that was the limit. I don't think #4 is fitting in there either, but not certain on that one.
@@LithiumSolar Thanks for the help! It seems that China companies consistently call out 0.2576 inches in diameter (which fits). US sellers have various numbers and not the same.
@@LithiumSolarWE NEED A BETTER ANSWER??? IT CALLS FOR #2. WHY . BUT ONLY ACCEPTS #6. THATS AN ISSUE???
wow thats is a big boy!
Nice 👍
If you were today looking to buy a 12kW output system, using either a single unit like this one, or dual paralleled units, and you needed to minimize standby consumption of the inverter; what unit would you suggest?
If I were building a 12kW system today, I'd be using a pair of the MPP Solar LV6548 inverters.
hi, do you mind sharing your charge settings for lifepo4 with this inverter? thanks
The inverter comes pre-programmed. There is an LFP selector for the battery type.
@@LithiumSolar thanks very much for that info.
What about AC coupling? If I were to land 60 Amps of 240 volt solar microinverter input in the backed up loads panel, what would happen?
That's a very good question. I've heard of others doing it but I've been afraid to try out of fear of blowing up my inverter. I asked AIMS and their official response was NOT to do it.
@@LithiumSolar Bummer. The amount of solar it accepts through the DC channel makes it pretty much a toy for purposes of off grid. Now, there was an option to attach a separate charge controller. In that scenario, is the input DC voltage still limited to (what was it?) 150 volts, or something? Or, would this allow more total wattage through some tech witchery? How much PV wattage could be run through the DC PV inputs with a separate charge controller?
How to buy? Thank you
Looks a lot like an AIMS? Is it a sub brand?
Agreed and am not entirely sure. I've been trying to figure this out for a while now.
I replaced my MPP Solar LV6048 with a Sungoldpower 10kW split-phase inverter, and the charge controller appears to be garbage. The charger efficiency shows something around 50% efficiency by my calculations. I had no problem fully charging my 10kwH battery pack on sunny days with my previous inverter, now with even having trackers, I rarely have a full day now. Their support have been terrible so far... And yes, the power consumption of the inverter itself is pretty bad, compared to the MPP Solar I replaced it with. Noticeable difference in battery drawdown overnight.
You mentined your battery storage is outside. Make sure you have freeze protection for the battery shed batteries I may have missed some of your videos, but I just wanted to mention it in case you didn't think of it. I built low temperature charge protection into my dual 12 volt batteries for about ten dollars each.. Silicon 12 volt elements and a temperature sensing relay.
It's insulated and heated, but thank you for the reminder :)
280 kwh battery bank? you are nut hahahah ... I love it. wish I can build that big :DDD
Would the external temp sensor not being connected have something to do with the fan running?
Solar was not hooked up. Also the temp sensor for the inverter is hooked to the MOSFETs
@@JM-yx1lm And the mosfets were not hot which can mean a defective sensor or open circuit leading to a default fan on. Solar input is not connected to the fan circuit.
I did plug in the battery temp sensor at the end to see if that made any difference and it did not unfortunately.
@@LithiumSolar It won't. The page of the manual that you showed indicates that there is an "AC fan", and a "DC fan." Reread the paragraph above the table...it's pretty clearly spelled out.
The AC fan is connected to the AC output of the inverter--so if the inverter is producing AC output, that fan will be running. In Power Save mode, the AC fan will pulse on and off every time the inverter switches on and back off again.
The DC fan(s) are temp controlled.
@@sidlori1592 Interesting, I see what you're saying now that I re-read it. That's not what I expected though. I'll have to open it up again and see how it's actually wired. Thank you for pointing this out.
Clothes drying with heat is an extremely energy intensive activity, especially costly when powering it with very expensive batteries. To evaporate liquid water to vapour requires a phase transition and huge thermal energy input.
Yeah, it uses a LOT of power.
@@LithiumSolar My point being, the use of solar energy is to be forward thinking and inteligent, but anyone drying clothes by pv battery energy is not smart and cares not about resource consumption
@@michellelewis3063 - the dryer acts as a great tool to exercise an inverter!
It is best to try not to be judgmental of others, since outsiders often do not understand the personal situations of others and there is no reason to get into someone else’s business to find out judgments made in ignorance may be completely unjustified. John 7:24
@@DavidHalko I refer to physics, latent energy, I would ask you to look it up :)
@@michellelewis3063 : I believe the point is addressing your unfortunate and judgemental phrases "not smart" and "cares not". Let us assume the following: 1) At least one person in the residence has significant environmental allergies (hay fever, grass & trees, etc), so hanging clothes outside to have them air dry outdoors is not an option. 2) There is not enough room inside the residence to hang the items to be dried. 3) The residence does not have access to a power grid. 4) The owner wants the smallest carbon footprint as possible. 5) The residence has terrific solar positioning and orientation. 6) The solar & battery setup has ample capacity to run a normal household load and the dryer (so other household load are not sacrificed for the sake of drying clothes). 7) Geothermal energy is not an option (either too expensive, or something else). Now, given these parameters, what method of drying clothes is "smart"er than using stored PV energy? I guess you could say to use the generated PV power directly from the panels (through the inverter) during peak PV power generation, but the normal daily household load might dictate that clothes washing/drying be done late at night, when other power requirements are minimal. I believe this is what David H is getting at: "the personal situations" (the parameters I listed above, or even more restrictive ones) might dictate that drawing stored PV power from one's "very expensive batteries" just might be the "smartest" (or even the *only* reasonable) solution.
New Sub Thank For The INFO & Video Me 3 x XW 4860's 15 years Old Working So Good 2 ac's & pool All Loads On ALL OK Sanyo HIT Solar 12kw & 2 wind Units
What's 6 KW version of the sun gold inverter is absolutely silent except for some slight Transformer hum and it has a variable speed or multi-speed fan that comes on at low speed from time to time when there's a reasonably heavy load operating. The fan noise on this 12 KW model is disturbing to say the least mine will be installed immediately adjacent to the recording studio and so that noise will be a problem.
I purchased the 15K unit 48 volt. I'm currently running lead acid batteries and the fan is constantly running like you said from the moment I turned it on. the unit has not once that I've seen gone to charge controller mode it stays in inverter mode the whole time and I've never had a problem with it running out of power lowest batteries ever got was 49 volts when I had it in a 24 volt configuration with out back charge controllers and 24 volt 15,000 watt inverter I was running out of power in the winter time. So did you find out from the company why the fan is always on?
It seems (based on what others have said) that it just doesn't have the fan control circuitry that other similar inverters have. It seems like a huge oversight in my opinion as something small like this would have reduced the inverter's power consumption quite a bit.
@@LithiumSolar thank you for getting back to me I wondered about that fan so I appreciate the invite.
@@LithiumSolar I have had AIMS 10kw LF inverters. The first one was taken out by lightning strike. The fans ran all the time for about two years until the strike. Aims said that was normal. I bought a second 10kw LF after the strike and its fans only come on when needed. I have run this one for 3+ years and the only problem is that it will shut off when charging off grid/gen. It gets hot after 3-10 minutes. I charge the batteries using two Midnite 150 charge controllers. Which have been working for 5+years with no problems. The fans should not run constantly. I will not buy another Aims or clone. I did buy two EG4 6500 EX 48 from Signature Solar which are bad right out of the box.
How much over the 12,000watt output will this Continously put out in over rated Watts? 5%,10% at 240volts? Was Hoping as high as 20-25% Over Rating. Please do Respond! Thanks.
This information is spelled out in the user's manual. Please check.
Sounds cool, but what is the use case for this sort of equipment?
I know 2 people who has an electric off grid home. Both uses electricity for everything, heating, cooling, cooking and even an electric car.
Whole house UPS.
Do you do any consulting online? I have not been able to get my solar running using this inverter and don’t know what I’m doing wrong. I am willing to pay for your consultation to figure out my issues using videos of my setup. If yes, we can figure out how to DM off TH-cam.
I do not do personal project consultation. I am not an electrician nor authorized to give any sort of direct advice.
I was very interested in this brand and model but realized from the specs on the manufacturer's site that the total harmomic distortion of these is around 10% which is not considered clean power. clean power is defined as a THD of less than 6%. would love to see this output on an oscilloscope to see its waveform.
