The soft starter finished it's relearning process and the inrush current of the HVAC came down from 61A to 52A. I changed the settings on the Growatt from Li to USE, disabling comms between the Inverter and the batteries and the Growatt was able to start the HVAC unit. Running current from the batteries was about 105A, with total AC power draw about 20A @ 240V. There must be something about the Li mode that causes the low voltage error 04 prematurely.
Tomorrow I will set up the generator and have it running the Chargeverter while the Growatt powers the house and the HVAC. I want to see how quickly the batteries go down while still being charged at around 4kW. This whole experiment is to see how the system performs in the event power is lost during a heat wave. The generator alone could never start the HVAC unit.
