My system feeds the grid even though grid feed in is disabled. Battery power is sometimes used for this even though the battery has not been fully charged.
I have 2 Multiplus -II 48/5000/70-48 inverters set up in parallel, My solar controllers are a SmartSolar MPPT VE.Can250/85 and BlueSolarMPPT VE.Can 250/100. I have two sets of 10 and 12 525kw panels, a Freedomwon e-tower (4 units) and a Cerbo GX.
I am charged for power exported to the grid and would like to avoid this, particularly as the system seems not to be prioritising battery charging but servicing loads and the grid.
Grid setpoint is 100W
Thanks for the help!
