Charge controller not producing what it should

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?

Please confirm the firmware versions of each of the components of the EasySolar, Eg MPPT, Multi, CCGX.

please advise the firmware version for the easaysolar and the other items

I need to 100% know you have the latest. sorry to be a pain but I get caught to many times.

Then I would suggest you get connected to the victron VRM and we can then have a look.

post your VRM number and someone will request a connection .
