Enerdrive ePOWER 12V 40A+ DC2DC Battery Charger with MPPT Solar Input

Enerdrive ePOWER 12V 40A+ DC2DC Battery Charger with MPPT Solar Input

The Enerdrive ePOWER DC2DC+ is a fully automatic, multi-stage, multi-input charger that charges your house battery from the vehicle alternator while driving, or from solar via its built-in MPPT regulator when parked. Source switching is automatic and handled inside the unit, with no external relays required.

It runs from a 12V or 24V vehicle input, accepts up to 45V/800W of solar, and includes a lithium charging profile alongside Gel, AGM, Flooded and a fully custom profile.

Features

• Two independent DC inputs — engine and solar both charge a single house battery bank
• Built-in MPPT solar regulator — up to 45V / 800W solar input
• 40A output — user-selectable from 5A to 50A in 5A steps (default 40A)
• Multiple battery types — Gel, AGM, Flooded, Lithium or custom programmable
• Programmable LCD — shows charging source, status, voltage and current
• Temperature sensor included for more accurate charging
• Fan cooled — thermostatically controlled for output at 40°C+
• M6 screw terminals for large battery cables
• Load-based regulation so the charger moves to float when it should

Enerdrive is a leading Australian power specialist, part of the Dometic group, and this charger is backed by a 5-year manufacturer's warranty.
