you just need to get forceful with them. I bought 6x 200ah batteries and they sent me 6 new boards (was a common problem with BMS boards). Then one of the power switches failed.... they walked me through it with their technician and once diagnosed, they just asked if I can just buy the...

I'm sorry you had a bad experience but they are definitely NOT SCAMMERS. I and many others on this board have gotten batteries and have gotten after purchase support. Communication can be slow at times, and you do run into translation issues some times, but they are not scammers. they are a...

I bought mine from Rosen Solar in China, but they will no longer sell to US (I bought them over a year ago). Not sure if they are UL certified, but I am completely off-grid, so didn't really need that certification.

I'm in the US - I can share my settings... just need to get back there and write them down.

Great - I'll give that a try.... I wasn't using the TOU section at all.

I have 2 Deye 8k inverters in a fully off grid house. I have a propane generator tied to the grid input and a smart load tied to the gen input for my EV charger. But I have never been able to get the generator to turn on. Even if it’s running it will show 1watt coming from “the grid” but it...

Dunno.... I guess I assumed that the Inverter had a BMS and was doing something since I hook up the batteries to it with a network cable, but I really don't know (Again, I am coming from a place with minimal knowledge). I also thought I read that in another post, that you can use the inverter...

Sweet.... I will try that out next time I'm at the location..... I may also try to run them off the battery BMS instead of the inverter BMS... I read in another post that this might be helpful.

seems to be different batteries every time.

so how would I correct that.... is this where the reset would come in? I saw that there is a reset button on the batteries, but havent used it.... So if I let all the batteries charge to 100%, and then hit the reset button, does that set the SOC for each battery?

I never had them working properly before the BMS boards got changed. Essentially batteries started dropping dead from day one, so they shipped me new BMS boards (since the bad diodes was a known issue) and I installed those new boards myself.... but never did any type of reset on them

Perfect! I'll try that..... With these batteries, I also had to replace all the BMS boards (since they had a batch of bad diodes), so maybe that is what is going on.

So if one battery isn't discharging, couldn't it be the BMS shutting it down (raising the drawbridge)? Similarly if there is a difference in SOC, couldn't it be that BMS is shutting off some of the batteries at some time after they started to discharge which would account for the difference in...

I don't have (or know how to access) BMS logs.... but this is more what I was thinking the issue was.... something with the BMS, because it doesn't always seem to be happening all the time. sometimes they all discharge the same, and othertimes there will be one or two that are not discharging...

I'll have a look.
