The HONGGE is a DC-to-DC charger that tops up a 12V or 24V house battery from a vehicle alternator or a solar panel. Its built-in MPPT controller and solar-priority switching keep the alternator load low while getting more usable power from a solar array. It handles four voltage combinations and works with LiFePO4, lead-acid, GEL, AGM and calcium batteries. It suits van, camper and overland builds that want one box for both alternator and solar charging.

This DC to DC battery charger tops up a 12V or 24V house or leisure battery from a vehicle's alternator or from a solar panel. It switches between the two sources and gives solar priority, which keeps the load on the alternator low.
A built-in MPPT controller draws more usable power from a connected solar array. The charger delivers up to 40A and 520W at up to 94% efficiency.
It has four charging modes: 12V-12V, 12V-24V, 24V-12V and 24V-24V. Two DIP switches set the battery type. It works with LiFePO4, lead-acid, GEL, AGM and calcium batteries, and with over 95% of portable power stations.
