I have 3 overkill solar 24v BMS in my 280ah batters, and I'm having several problems. I sent an email to the company but only got an auto response on what they will respond to. Makes no cense I know but my problem is not on the list they sent.
Problem 1. All 3 BMS are locking when 1 cell gets to high in volt, wile locked they will not even allow discharging so its as if I don't even have the batteries.
Problem 2. I balanced the cells before I used them but after a few months the cells are way off balance now.
Problem 3. The BMS show 1 over all voltages of 27v but the main Bus bar they are all connected to and the shunt show 28.4v.
The only why have be able to unlock the BMS is to reset the capacity but then I do that the capacity drops for 100% to 60%.
What am I missing?
