can the starter be 12v and the house battery be 24v?

Yes. The Orion I am using is a 12/24 step up transformer. My alternator is 12v fused at 30a running 2- #8 THHN wires back to my transformer 12v input, and 24v output charges my house batteries while I am driving

Bought this for my boat to charge a Lipo4 battery. It was very easy to install and configure using the bluetooth interface. It's not too big to be effectively installed in a small hatch but you'll need to watch out for airflow as the unit can get a bit hot. That said, it will charge just about any battery - it's quite versatile. It's not cheap but who wants cheap on the water? There's a reason you see victron on so many sailboats, etc.

Top, configuration parfaite, ne chauffe pas tant que ça, un peu gros et lourd par rapport à la concurrence mais c’est aussi ce qui fait sa solidite
