DMT1250

Designed for charging batteries from PV solar or the engine battery when AC household power is unavailable.

50A DC Battery Charger

Abso DC to DC Charger Series

The DMT1250 DC – DC chargers are the smart alternative for leisure or commercial use. They provide the ability to charge batteries from two input sources; either via a PV solar panel(s) when stationary or via from the engine/alternator while driving.

Features include:

  • Dual Input Capability: MPPT solar input and household battery.
  • Multi-stage battery charger ensures that your batteries are charged the way battery manufacturers recommend.
  • Small footprint with extremely compact design.
  • Saves money by maximizing battery life.
