12V 40A DC to DC Battery charger.

The EN3DC40+ is a programmable DC to DC charger featuring separate inputs for engine and solar charging. The solar input is regulated with an MPPT algorithm with a maximum OCV (Open Circuit Voltage) rating of 45V. The charger output is 40A up to 40°C but can be decreased for smaller Ah batteries.  While the engine is running the charger will use the engine input, otherwise the solar input will be used for charging.  Engine charging is autosensed from the start battery voltage, but an ignition signal can be used instead.  Temperature sensor is included but not required for DCS batteries.

The charger will take up to 600W of solar however depending on the efficiency of the solar PV panels 800-900W can also be wired into the charger.
