Good day,
I am running a multiplus 2 with ess setup with south africa grid codes, during a recent cable theft I tried to charge the system using a backup generator with no luck.
I have a manual change over switch in the main DB switching all power between grid and genorator.
The multiplus gets power from the mains and the output go to a dedicated supply DB.
I tried changing the system from grid to generator on the cerbo, disabled Lom, enabled weak ac, disabled ups function and even triet to put the inverter to charge only but it did not connect to the generator supply
