I am re-installing a MultiPlus as an ESS-system where it initially was designed/configured as a OffGrid system. There is an energy meter on AC1 to measure incoming AC coupled solar.
I set the ESS for 'No Grid meter' but still it is taking the solar meter as input for power balancing, leading to trying to charge the batteries from the grid even when they are almost full and plenty of solar is available.
Disconnecting the meter from the CCGX got rid of this behavior.
