I have 3 x 48/5000/70 multiplus in a 3 phase configuration which is fed by a 15kw Fronius 3 phase solar inverter.
Lately the SOC in VE Bus does not match the batteries. This causes the SOC to stop st 90% SOC when the batteries are at 57.6v which is the absorption voltage. Sometimes it will sit at 90% for 3 or more hours waiting for the batteries to meet the SOC before going into absorption. I've tried everything I can think of but I'm obviously missing something. Even my installer is at a loss. Can someone please help. Thanks in advance...
