We have a growatt SPF 6000. Program 01 "SOL". Everything works great, except at night when the battery goes below 50% the grid comes in which is fine, however when the battery reaches 100% soc then the inverter faults on code 03. My supplier changed the battery but no luck. Is there a way to set the inverter to stop charging at 100% or even 99%. Like I mentioned everything else works great
