new installation, i havent touched defaults. I only have ac when connected to shore power. AC in to multiplus, ac 1 out to distribution panel. Everything functions when connected to shore power, batteries are maintained, ac and dc sides powered. disconnect shore power then only my dc side has power. I dont have an interface for the multiplus but just ordered BT dongle so i can check my settings.
multiplus 24/3000/70, Mppt 150/45, 24/12 converter, 6- 24v 50ah battleborns
