I have a Easysolar 5000 with lead acid batteries and I can grid feed. I am running ESS with keep batteries charged. I have set the float voltage to 54V and the float voltage on the charge controller .4V higher. I have 5.28kWp PV installed, but the PV production only goes up to roughly 3kW at 10AM and then drops to 2.5kW till the late afternoon. When I discharge the batteries a bit the PV opens up but only until the batteries are charged again. The system rarely grid feeds more than 2kW. I have tried changing the ESS setting to optimized and cycling the batteries to 95% but the solar still doesn't open up. Grid setpoint set to -5500W. Tried with and without DVCC, no success. Any suggestions?
