Note: this is for an off grid house, not a boat, so space is not an issue. Our sua4500 generator has died. Since we are in the process of installing a whole new Victron system, we would like to replace it with a generator that is known to be compatible with Victron. What brand and models should we be looking at? We have a Multiplus II 48 3000 volt inverter charger and 2 Fortress eFlex 5.4 kWh 48 volt batteries. Would be nice to set up a relay so we can lush a button or switch to fire up the generator instead of pulling a starter rope. Thank you!
