I am designing a 10 kW PV no break supply system including 3 x MP II's (ESS AC PV on ACout 1), whereby I will have extra PV available at times. I have the availability to thermally bank any excess, when certain conditions are met, through my home automation system.
I have looked at the MODBUS map but cannot determine which of the fields will give me total PV output from the Fronius.
Any help on which fields I require to initiate a control command when PV output is greater than total load requirements, would be greatly appreciated.
