My Solar Exploits
Having some issues with batteries. Had a battery undervoltage fault (on battery #2) yesterday which forced the inverter to grid bypass mode.
this was because one cell (of the sixteen in each battery) in one (of the five) batteries dropped below a threshold and more or less shut the whole system down.
I've now gone through the process of charging the entire battery system from the grid (overnight) but one battery (battery #3 ..i.e. not the one that had the under voltage cell) would not/did not fully charge to 100% State of Charge.
I figured resetting the battery might clear it but that had other consequences where were that it went back to normal operation once the uncharged battery was offline. So now I have a higher state of charge overall but mismatched battery levels (which actually was likely what started this whole mess and the system has never been fully charged or fully discharged since the batteries were all added at different times and in different states of charge.
Lordy....I didn't know what I was getting myself into. I just assumed between the Inverter monitoring, charging, etc. and the BMS (battery management system) built into each battery this would all take care of itself but so far I'm finding it a FULL TIME BABYSITTING JOB!
Plug and Play My ASS!
