Ac coupled ess not charging

Have 2 multiplus 2 units in parallel on single phase grid connected. Setup as ESS using ac coupled solar on ac input (1 phase of a split phase turbine). System discharges battery but does not use available power to charge the battery. Victron current sensor used and is now calibrated over 24hours. Using internal grid meter instead of external. Ccgx and both multiplus units running latest software.

Hi

What are your ESS settings? The AC input AC1 coupled inverter will need it own energy meter to work correctly, so the Victron knows to what to use for power for charging the battery bank.

I have system done this way and it works a treat.
