I have a Multiplus 12/3000, Cerbo and 4 MPPT solar controllers. Currently I have the system programmed with assistants to give priority to solar until battery state is 70% then use shore power.
When There is no solar output this requires the batteries to run down to 70 percent and then shore power will charge them and provide pass through 120v power.
I am trying to find if there is a way to set the system up so that when there is no solar production the system will automatically switch to using AC1 in. Suggestions?
