I have a Multigrid with a Byd B-Box and AC coupled SMA PV inverters. This works well as ESS and can also switch to island mode, using the Battery and PV inverters as power supply.
Is there a reasonable way to charge the battery with a diesel or gasoline generator in case of a longer power outage (and bad weather)?.
I guess I cannot connect the generator instead of the mains supply because it is not stable enough. Or can this be done?
Or can I connect an additional charger (powered by the generator), in parallel to the multigrid to the battery?
Regards,
Martin
