We are doing a Victron lithium conversion on our sailboat. The boat is currently wired for two 30 amp services (legs). There is a magnum inverter charger that has one leg passing through to panel. (Outlets) The other leg, (air/heat and water heater) going to panel. We want to upgrade to a multiplus II, and we are planning to install four blue smart 330 batteries. We will have plenty of battery juice and solar to have the ability to invert all loads if we want to, and want it wired so. I’m having trouble finding the best way to do this without converting the boat to a single 50 amp service. Lots of mixed feelings and threads gone dry around this very topic on forum. I’d like to nail down the best and most correct way to do this! Thanks!
