I currently have a Multiplus 24/3000, but am thinking of replacing it with a Quattro 24/5000, both for more output capacity and maybe to handle 100A of charging input from a 240V split-phase (“50A”) outlet. As far as I understand, a single Multiplus can use one of the 50A legs but two configured in split-phase mode would be required to handle both legs.
The PDF manual online claims the 120V Quattro can handle both legs of input but that 240V output is not possible off the inverter. That’s fine with me - I only care about 120V. But can it use both legs for battery charging, or is it just something passed through?
My goal is to charge my batteries using both 50A legs if possible. I only have 120V appliances and would prefer to run single appliances up to 3kW - beyond what a single Multiplus can do. If a Quattro won’t help me, then maybe I need to consider a second Multiplus instead. But with split-phase, I don’t think I’d be able to run anything beyond 2.4kW for long, if I understand correctly. Any advice greatly appreciated!
