Enerdrive ePOWER DC2DC+ Battery Charger Technical Guide

Overview

The Enerdrive ePOWER DC2DC+ Battery Charger is designed for the rigorous Australian environment, offering multi-stage, multi-source charging capabilities for DC systems. It can charge from an alternator connected to a battery or through solar power, incorporating an in-built Maximum Power Point Tracking (MPPT) Solar Controller. This charger is suitable for a wide range of battery types including GEL, AGM, Flooded, Lithium, and allows for custom profile creation.

Key Features

• Multi-Input Charging: Two independent DC inputs for engine and solar regulation charging one house battery bank.
• Connection: DC M6 screw terminals for large battery cable connections.
• MPPT Solar Regulator: Dedicated regulator for efficient solar charging.
• Battery Compatibility: Supports GEL, AGM, Flooded, Lithium, and custom profiles.
• Vehicle Input: Compatible with 12 or 24V systems, with a maximum solar input of 45V/800W.
• Cooling: 40A output up to 40+˚C with thermo-controlled fan cooling.
• Display: Programmable LCD for monitoring source, status, voltage, and amperage.
• Temperature Sensor: Included for accurate battery charging.

Installation and Wiring

Towing Applications (e.g., Caravans, Camper Trailers)

• Important: The negative cable from the start battery must connect to the DC2DC input terminal for correct operation.

Vehicle & Marine Applications (e.g., Motorhomes, 4WD’s, Trucks)

• Smart Alternators: For vehicles with smart alternators, the negative cable must connect to the vehicle side of the Battery Sense Module.
