RV Battery Charger

An RV carries two electrical worlds. The chassis system starts the engine and runs the driving loads. The house system runs the living loads: lights, refrigeration, ventilation, communications, and charging for devices. The house battery sits between them, and the DC-DC charger is what keeps it charged from the chassis system while driving, so the house loads do not drain the starter battery and the house battery is full on arrival.

The charger category on this site lists RV as a supported context for its charger lines, and the bidirectional series states support for charging while the engine runs, which is exactly the RV driving case. The series serves 12, 24, 36 and 48 volt lithium and AGM batteries, so an RV builder should match the model to the house bank voltage and chemistry, not to the chassis voltage alone.

An RV installation also raises practical questions the inquiry should cover: where the charger is mounted and how it is ventilated, how the house and chassis banks are isolated when parked, and whether the charger is monitored, since the bidirectional series communicates over RS485. Before ordering, confirm quantity, price and delivery time. Certificates are available upon request.
