I am trying to build a battery backup for some AC loads that can also be powered by solar.
The system schematic is attached.
I'm trying to verify that battery protection would function in this system, as the Cerbo would be in control of both MPPTs and the Multiplus using DVCC (and therefore nothing needs to be attached to the charge disconnect of the BMS). As I understand it, I would need to configure this as an ESS system.
Am I correct in understanding that it is impossible to combine Multiplus+battery+MPPT without a Cerbo if I wish to power loads from solar when available, grid when solar not available?
