I have installed a Multiplus II on my boat. I also have solar panels connected through two MPPTs, and a Smart Shunt connected to the house battery bank (5 - 12V AGM batteries). The system is connected to a Cerbo GX with a touch 50.
My question is this: Is there an easy way to prioritize solar power over shore power when the boat is connected to shore power?
I have seen many posts from a few years ago but there seems to be no clear answer. The ideal situation would be when the sun is shining the batteries remain at 100% SOC and the solar powers the boat. If the load exceeds the solar output, the Multiplus II would make up the difference using shore power.
I look forward to hearing back from the community.
