So are you suggesting I simply don't start charging the batteries until 20% or 10.

I have a Growatt SPF 6000t inverter. Operating 3years no problem. Today it is faulting "01" fan fault when the large transformer fan turns on. The fan operates fine however fault mode turns off the charger and does not reset after fan turns off. Any ideas anyone? How does the unit sense the fan...

I changed a setting in daly smart bms app "collect board settings" and comm board went dark, beeping and no communication with bms to change back. Using new home storage bms with separate comm board. Any help "with what have I done?" And how to factory reset without bluetooth.

Hello all, I have one of the 43Kwh lithium batteries recently auctioned at Battery Hookup. I am reworking it for residential use ie 3 - 16 cell batteries in parallel. I have a simple question. I would love to incorporate the Connectors and Switch that are included on the original battery bank...

Thanks for you time and guidance.
