The savings with these battery kits is VERY appealing! BUT - there seem to be endless people experiencing BMS interoperability and compatibility issues with mainstream or supposedly supported inverters. These problems are detailed on multiple DIY and other solar forums and Facebook groups. Yes, even on the Facebook groups and forums of the manufacturers themselves. It is not just the JK BMS(s), but Basengreen and others. Endless problems requiring massive time investments in testing, trouble shooting, researching, constant firmware updates, building your own cables to resolve incompatible communications cable pin-outs, SOC and balancing issues, etc., and DIYers forced to spend 10s to hundreds of hours to try resolve unnecessary problems and issues, some of which have caused damage to their cells. Moreover, some have to identify and pull individual cells and treat them separate from the other cells, creating the need for massive wasted time in monitoring, extra hardware, extensive downtime not to mention the expertise and knowledge required, etc. To add insult to injury, many people report extremely poor customer service/tech support introducing massive delays, unless of course, you're an, "internet Influencer." I actually like a lot of this stuff, but I'm reaching the conclusion (personally) that the savings are NOT worth my time in this case. I just don't have the time to fall into one of these endless technical black holes. Everyone's situation is different, so I understand and respect those that feel it is worth their time. NATE - you are providing tremendous value and I appreciate you and ALL of your efforts! The maddening thing is that just some basic communications standards with BMSs and inverters would likely eliminate 98% of these unnecessary challenges. Maybe we are just early adopters and hence we have to put up with arrows in our backs...

@MrPbologna it looks like it has an built in battery, and that battery is what gives it enough amps to run, so it's not direct from solar.. it takes 400w of pv input for charging but takes 550w to run the ac. You would need a converter that can replicate the battery DC output in volts and amps. You would need a converter large enough to handle the surge when the compressor starts. Probably is less than 16a. The specs don't show this info. How is the battery hooked up to the ac.. It's the battery removable ..

Hi. Thanks for the sub. The unit will consume as much as 1600w but will run on as few as 200 to 300 depending on temperature needs. For example, if the room 70 degrees and you set 70 temp, it will basically idel at 200w. No work needs to be done. I tested in winter, so I was unable to get it to pull a ton of power while cooling.. I used 6x 370w panels in series @ 41v each.. so 2kw and 246v. You can run it on the economy mode, and it will consume just 600w, but it will only maintain a certain temp.. 88 degreese . If ambient temp goes higher, it won't try to maintain. So you will want at min 1600w PV to get full power.. the delay is to protect the compressor between start and stop events. No soft start.. possibly built in.. not sure.. very low surge on startup..

Fans which suck dust into the internals and boards are covered, surely that doesnt help cooling! Victron was also much easier to setup and find specific settings.

Seems to me there could be a temperature issue with these batt boxes. The cells are compressed together and the box is not vented, once that temperature builds up it will be difficult to lower it without forced ventilation like a desktop computer? and even then the cells will not cool easily because they are so tightly packed together. I see from the 280Ah+ spec sheets that cycle life is halved once temps get up to 45C compared to 25C. Is this an issue or am I worrying unnecessarily...
@natesdiysolar 11 күн бұрын
Although ventilation holes would be a nice feature, it would not necessarily be for heat build-up. These types of cells generate very little heat themselves, if any. These cells are very commonly sealed in some type of sealed container like in EV cars, and they are sealed cells that do not vent unless some extreme rare circumstance (safety feature) and if that happens, the cells are probably ruined. The BMS will actually create more heat than the cells will, and that's only under high sustained loads. But even the BMS is designed to dissipate this heat. I would be more worried about outside environmental factors and ambient temp than I would the internal heat. In fact, if you are in a cold climate, it's recommended to keep the cells warm. I have a heated battery build video if you want to check out. Hope this helps. I actually thought about doing a video using PC fans and a temp controller, but this would be if you were going to keep the battery in some closet outside with direct sunlight heating up the cabinet. My batteries are in the garage, and I have an ac unit to keep the equipment cool, and the bms reports 30c max when the garage is at 89 to 92 degrees ambient temp... its actally cooler inside the box according to the BMS. The BMS has 4 temp sensors that will shut down the battery if the temps get too high. I'm talking 60 to 70c, and this is factory default.

Seems when I replace them with LFP I can get them inside and keep the cabin at 25 C max. Would they stack okay without the lids on? that would help dissipate any excess heat quickly.

Unfortunately, I do not have a good answer for you as I am also wondering about the same issues. I'll tell you what I do know.

I will attempt to connect to my mpp solar inverter at some point. The eg4 inverters seem to require battery communication, so if that's what you are planning on doing, please check with the seller if there is a user or stand-alone mode that does not require comms. If so, it should be fine just going based on voltage.. that's what I'm doing now.. both seplos and the jk bms. I would start with reading the jk Inverter Bms manual. I will try to get a page up on my website in the coming days with a link to the manual. Sorry, I don't have a better answer at this point.

@@natesdiysolar It is hard to imagine why the battery manufacturers and the inverter manufacturers don't just establish a communication standard/protocol for the base functions of a BMS. As a software engineer, I can assure you that it would save massive time and money for both sides and it would promote increased sales because they could avoid making all prospective customers worry about incompatibilities and shoulder the burden of uncertainty and risk. I suppose some inverter manufacturers that ALSO sell/make batteries might think it works to their favor to keep their BMS protocol proprietary and force customers to buy everything from them. I'm frustrated though by any inverter company that claims they are battery agnostic but doesn't publish their BMS communications protocol at minimum. The result is that the inverter company needs to be wildly better than its competitors if they effectively force you to buy wildly overpriced batteries to work with their inverters. It sounds like there is blame on the other side too. Why doesn't the company making the JK BMS do everything possible to work with the top 20 inverter manufacturers worldwide ensuring communications compatibility? Do you know who makes the JK BMS?

This is the best battery box on the market at the moment together with the ELL DIY battery box with JK Inverter BMS, but both are not perfect yet. I don't like that the communication cable between the batteries placed on top of each other runs through the touchscreen in both boxes. ELL should fix this in the future. Also, two main plus and minus terminals would be better as one in ELL DIY battery box, just like Yixiang battery box has. Second PCB connectors in Yixiang battery box are not needed, the JK Inverter BMS has sufficient active balancer integrated into it.

Yes they certainly could use improving. I wanted to try the pcb connectors and see how fast I can balance a pack. Even with the JK bms it took a day or so.. way faster then the seplos lol.

Was it the ELL that had that junky bus bar to breaker configuration.. I do not like that.. give me a nut and bolt any day..
@tiborchren 10 күн бұрын
@@natesdiysolar Yes, ELL cut the busbar width in half when going into the breaker. They should extend the end of the thinner busbar and then bend it back so that the busbar end cross section would be the same. But ELL basically follows the comments and improves their products based on what the community needs or wants.

UPDATE: They now send out non-conductive washers for the PCB screws. There is an issue with the PCB mounting screws that can cause a possible short in the BMS. They notified me of this and I noted it a couple times in the video @8:00 and at the end during my conclusion. They are working to resolve this. This is so far the best kit I have found. Its easy to build, and with cell prices, the way they are there is no better time to DIY! Be sure to watch the price 23:23 comparison segment in the video near the end. You will be SOCKED!!

How do you like the seplos bms please?
@natesdiysolar 18 күн бұрын
Well . The v2 bms is slow to balance initially but once you get to using it it's really not that bad.. it functions lol. The display is lacking compared to the jk Touch screen. I'll be doing a video about balancing with this bms. But it was frustratingly slow. If you want quick and easy just use the JK inverter bms or an externalbalancer. Videos coming out soon on both of these bms. I can't really say I'd recommend it over the jk bms... that said I haven't gotten into the comm/inverter functions yet... the v3 does have a 2 or 3A balancer so if they had a better screen AND balancer I would be ok with it...

@offgriddreaming5403 just be sure to pre balance by putting Cells in parallel or just use an external balancer for the initial balance. You will be fine. What Box did you go with..

Sir if the Amps came from the solar panel 6.92A How can you run 15A !! ?? Can you explain that please?
@natesdiysolar 19 күн бұрын
Hi. It's because the buck converter lowers the voltage. When voltage lowers amps increase. This is ohms law.

@@natesdiysolar so can l use it to run the inverter (12v,1000w) to run refrigerator(1/4hp, 220v) in the day when there is sun directly without adding battery or capacitor?
@natesdiysolar 19 күн бұрын
@tariqalshammari370 no. It's not strong enough for that. Refrigerators have compressors that require a lot of startup current. You could run a small inverter to run small AC loads like lights or small fans. 200w or less.. 200w @ 120v is just 1.6A. Don't forget loss due to conversion. So the max you could get from a 200w buck output going into a small 200w inverter would probably be around 150w.

Very informative testing video. For over one hundred dollars that Frogbro meter should be able to handle more than 60 volts or at least be fused. Thank you for saving me from buying and making the the same mistake. I'll use my clamp meter.

Why didn't you use the main lugs? I don't get it.
@natesdiysolar 26 күн бұрын
I wanted to have a main disconnect breaker. Also, if I add another pair of inverters for parallel output, I could just add another breaker . Besides that, 2x #4 may be too large for the lugs, but mostly, I wanted a main disconnect.

Is it hard to find someone to install this, if you can't do it yourself? I am not sure if an HVAC company would do the panels?
@natesdiysolar 27 күн бұрын
HVAC company probably would not install panels, but that is probably the easiest part of the whole thing. You could talk to signature solar, and I think they have a kit that includes panels as well as a video on how to instill the unit. I plan on doing an instill video, but not any time soon.. some time this year, though. If you want to run the unit at night, you will need to hook up grid power as well.
@jacquelineMeyers-is1zz 29 күн бұрын
Could you use something like for a lot more power, ie. AC etc..
@natesdiysolar 29 күн бұрын
For that, you would need a battery and inverter .. basically a typical off grid solar setup.
