The PTMDC 60A DC-DC MPPT On-Board Battery Charger is designed to charge auxiliary batteries efficiently using two power sources: solar panels or a vehicle alternator.

This intelligent multi-stage charger allows your solar system to prioritize charging the service battery, while the vehicle alternator continues to maintain the starting battery. It provides a reliable and efficient solution for maintaining power during travel and extended off-grid use.

With advanced multi-stage charging technology and multi-chemistry compatibility, the DC-DC MPPT charger supports Flooded, Gel, AGM, and Lithium batteries, ensuring optimal charging performance and longer battery life.

Ideal for RVs, camper vans, boats, and other off-grid vehicles, it helps keep your power system fully charged and ready wherever you go.
