I have 3 overkill solar 100a 24v Bms and I have had 2 strange problems in the last 2 days.
Problem one: (I think I fixed it) One of my bms was in over current protection and would not charge. The other 2 batteries were at 100% and not charging so I reseat the parameters and found that the 3rd one was trying to pull 150a. It should not have been doing this so what I did to fix it was disconnect half my Soler so it would only charge at around 60a until it was full and hit cut off. I have not see that problems come back yet.
Problem two: A different BMS will not charge more than 3-6a even as the other 2 are pulling in 30-40a. The others are in the 90% range and this one is only 76%, I have plenty of solar to give each one 30a + but this one will not take more than 6a. Once some clouds rolled in the amps of the others dropped to 14a and this one was -10a. I looked at my over all power and I was pulling in more than I can use so why is this bms -10a when all others are pulling amps in?
Until now the BMS have been working fine so what is going on?
