I have 6 strings of 280AH batteries on a 48 volt system. Last weekend I installed my 4 mpp 5048MGX inverters and programmed them to charge the way that off grid solar recommended on his site.
I tried looking at his bms settings and match them into the overkill but get confused on the language used. It could be the covid I've been sick from his week I dunno. But each battery bank seems to be off dramatically from each other even though they are all connected to a common bus bar.
The only thing I can think of that is effecting each pack is the settings on the bms. The only thing I've done is change it from. 100AH pack to 280AH and it automatically assumed 80% use at 224AH. That's all I've done on the bms. Oh also tried to change the names of the packs to know which ones which but won't work behind the first one. You know change the name unlink and hit refresh 2x . I've done that many times. Even Uninstalled the app and still didn't work.
These are the settings I used on the inverters
I also want to use the settings he has below the inverter settings in my overkill bms.

My Settings
I share here the settings of all devices I have configured for LiFePO4 batteries. As a beginner, it is very confusing to understand all these different options solar charge controllers, BMS, shunts…
