Jake, that’s a smart question. The Velit 2000R 48v ac kit # VE99QV will run while you’re on the move, but charging a 48-volt battery bank directly off a 12-volt alternator is tricky without specialized gear. Most vanlifers find a 48-volt solar kit like etrailer RV Solar Panel Kit 585 Watt # e59FV is the best bet for keeping the bank topped off when you’re off-grid - it’s simple, efficient, and works whenever the sun’s out.

Then, when you’re near hookups or running a generator, a 110-volt to 48-volt charger # 329-GX4820 is the cleanest way to give your bank a full, balanced charge. That combo keeps the AC happy both on the road and at camp.

Are you leaning more toward adding solar, or do you usually stay where shore power’s available?
