I have an existing parallel stacked installation of two 3000 multiplus units, a BMV 712 and a CERBO. These feed a 840AH battery bank on my boat, and a inverter panel that runs almost everything on the boat. Great installation BTW!
I would like to add solar to reduce my monthly shore power bill while tied up at the dock, and also decrease generator run time while cruising.
How to do it??? Would you use a DC coupled system, or AC coupled?
What settings or assistants would you use on the miltiplus to ignore the shore power and run on batteries at night? Then enabling the shore power if the batteries SOC gets too low?
How about when I leave the dock and am on generator power?
