1. INTRODUCTION Notice of Copyright Thank you for purchasing the Enerdrive ePOWER DC2DC 24V Battery Charger. With our state of the art, easy to use design, this product will offer you reliable service for providing a multistage, multi-input battery charger to charge the different types of batteries you have installed in either your home, boat, caravan, 4WD or commercial vehicle. This manual will explain how to use this unit safely and effectively.
2. WARNINGS Please read and follow the instructions and precautions carefully. This section contains important safety information for the Enerdrive ePOWER DC2DC 24V Battery Charger. Each time, before using the Enerdrive ePOWER DC2DC 24V Battery Charger. READ ALL instructions and cautionary markings on or provided with the DC2DC 24V Battery Charger, and all appropriate sections of this guide. CAUTION This unit is intended for indoor use ONLY.
3. PRODUCT DESCRIPTION The Enerdrive ePOWER DC2DC 24V Battery Charger is a multistage, multi-input battery charger to charge different types of batteries commonly installed in either boat’s, caravan’s, 4WD’s or commercial vehicle’s. Enerdrive’s ePOWER DC2DC 24V Battery Charger package includes the following items; 4.
additional loads connected to the battery while the DC2DC 24V is powered from either the vehicle or solar inputs. A Bulk re-start will occur when battery voltage drops below 26.6V DC. Lithium Battery charging algorithm Battery Current Smart Charging Feature Bulk The ePOWER DC2DC 24V Battery Charger will regulate its output based on the loads connected to your battery banks.
Note 3: Charger is acting as a power supply with selected constant output voltage and preset maximum output current. 5. INSTALLING THE CHARGER NOTE: The equalisation function although included in the ePOWER DC2DC 24V will rarely be used. To activate, the battery bank must be in float, and manually activated. A typical drive will not be long enough for the DC2DC function to complete the process.
6. CONNECTING THE CHARGER Mounting The Charger • Choose an appropriate mounting location. • For installing in an indoor location, the unit should be mounted vertically (with the battery terminals facing downwards). This provides the best thermal performance and drip protection. The unit should NOT be mounted upside down. • For installing in a boat or marine environment, the unit should only be mounted vertically (Battery Terminals facing downwards only) to provide adequate drip protection.
DC2DC 24V Battery Charger Connections Recommended Cable Length, Size and Fuse Protection.
Battery Wiring (Towing Applications): Battery Wiring (Vehicle & Marine Applications): For Towed Applications i.e. Caravans, Camper Trailers For In Vehicle & Marine Installation. i.e. Motorhomes, 4WD’s & Trucks. Please NOTE Please NOTE Vehicles with a Smart alternator, the Negative cable must be connected to the vehicle side of the Battery Sense Module. The negative cable from the start battery must be carried to the DC2DC input terminal for correct operation in a towed application.
7. UNIT OPERATION Understanding The Charging Mechanism Note 1: The Charger is powered by the battery connected to DC Output (CH1) and also supplied by CH2 or CH3 if available. The display will turn off to save power when Input Channel CH2 and CH3 are out of operating range. Operating from a Start Battery / Alternator (CH3) Normal Operation: Input Voltage Range Input Battery / Source 12V Input 24V Input 10.5V – 16.0V 21.0– 32.0V Normal Start-Up Voltage (Note A) > 13.2V > 26.
DC Input (CH2 – Solar / PV): PV Input Voltage Range Maximising your Solar Harvest using the DC2DC 24V 14.5 - 45V PV Input Under Voltage Shutdown < 14.5V PV Input Under Voltage Recovery 15.0V PV Input Over Voltage Shutdown > 45V PV Input Over Voltage Recovery = < 44V PV Charging Mechanism Maximum Input The Solar Input on the DC2DC 24V unit has a maximum rated INPUT current of 30amps.
Understanding the Display & Function Keys during normal operation Display Understanding The Function Key ‘MENU’, ‘SET’ And ‘SEL’ During Charger Setting CH1 - display is showing the charging battery info (charging status, voltage and current). Digital Display LCD with back lighting Digital Display Info : CH1 CH2 & CH3 Fault/Warning Charging Status, Voltage, Current Voltage Error code E01-08, Warning A01-02 ‘CH3’ Icon Flashing CH3 > 12.0V on a 12V Input system CH3 > 24.
Button Functions: Automatic Override Functions: • During normal charging operation, press once to change the display to show • CH1, CH2 and CH3 voltage. • During normal charging operation, press and hold for more than 3 seconds to enter Charger Function Setting Menu • When CH2 or CH3 is not available (voltage detect is below the sense voltage), display will turn OFF.
temperature and overrides the manual temperature settings and makes small adjustments to the charging voltage. If using lithium batteries, leave temp set to “NOR” (Normal) and leave temp sensor disconnected. Battery Temperature Compensation: There are three manual battery temperature settings on the unit (‘Lo’, ‘nor’ and ‘hi’). See the table below for voltage adjustments for temperature compensation.
Understanding The Protection Features De-rating Charging Current: When the charger senses the environmental temperature is above 50°C, the maximum charger current will de-rate to 1/2 of the set value (A01 warning code will display). The charger will recover automatically back to maximum charging current when the environmental temperature drops to below 45°C. E01 CH3 High Input Voltage Shutdown This means the unit has detected the input from the Start/Alternator has gone above 16.0V on a 12V input or 32.
E08 A01 A02 CH1 Output Short Circuit This means there is a Short Circuit on the DC output to your Main/House battery. If this is displayed, check the following: • The output wires are not shorted together. • The output wires are wired correctly and not reverse polarity. Over Temperature Warning When the charger’s internal temperature is > 60°C, the unit will shut down to protect itself.
