3. PRODUCT DESCRIPTION The Enerdrive ePOWER DC2DC+ 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+ Battery Charger package includes the following items; 1 x ePOWER DC2DC+ Battery Charger 1 x Battery Temperature Sensor 7.5 Meter Cable) Owner’s Manual 1 x Owner’s manual Enerdrive ePOWER DC2DC+ Battery Charger Owner’s Manual (Rev. 1.
4. UNDERSTANDING THE UNIT The Enerdrive ePOWER DC2DC+ Battery Charger is a fully automatic multistage, multi input battery charger with the ability to charge from either an alternator linked to a battery; or via solar power with the in built Maximum Power Point Tracking (MPPT) Solar Controller. With two inputs available, the house battery will be charged from either the engine while underway, or via the solar panels when stationary.
additional loads connected to the battery while the DC2DC+ is powered from either the vehicle or solar inputs. A Bulk re-start will occur when battery voltage drops below 13.3V DC. Smart Charging Feature The ePOWER DC2DC+ Battery Charger will regulate its output based on the loads connected to your battery banks.

NOTE: The equalisation function although included in the ePOWER DC2DC+ 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. The MPPT Solar function may provide enough time for Equalisation, but the best recommendation will be an AC powered battery charger. Battery Bank Size Recommendation The battery charging current rating is based on the battery size.
5. INSTALLING THE CHARGER WARNING Enerdrive recommends that all wiring be done by a skilled technician to ensure adherence to the best practice standards for on-board DC electrical installations. Failure to follow these instructions can damage the unit and could also result in personal injury or loss of life.
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.
6. CONNECTING THE CHARGER Chassis Grounding Connection BEST PRACTICE This Charger SHOULD BE CORRECTLY GROUNDED. The unit chassis has a stud point on it for grounding. Connect the unit’s chassis ground to the common ground point through the ground stud located near one of the unit mounting slots. (Battery DC negative is the best ground reference point in your installation) . DC Output Wiring WARNING: Correct DC Wiring Is Required The DC wiring used must be of appropriate size.

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.
current. This function is used to compensate for the use of long or thin wire between the Input Battery System and the unit input terminals. If the input voltage continues to drop below the <10.5V for a 12V system (<21V for a 24V system), the charging process will terminate and the unit will switch back to charge from CH2 (solar if installed) if installed. It will only switch back to CH3 if the CH3 voltage is >13.2V on a 12V system (>26.4V on a 24V system.
DC Input (CH2 – Solar / PV): PV Input Voltage Range 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 MPPT type ( approx. 97% efficiency) 500W *See Note below and “Maximising your Solar Harvest using the DC2DC+“ *Note: The recommended maximum solar wattage input for the DC2DC+ Charger is 500w. You can however “overdrive” the MPPT controller.
Maximising your Solar Harvest using the DC2DC+ The Solar Input on the DC2DC+ unit has a maximum rated INPUT current of 30amps. This means it is optimised for using higher voltage ‘grid’ type modules for best output performance The maximum achievable output using standard 20Voc solar modules will be approximately 35amps @ 14.4Vdc output.
Understanding the Display & Function Keys during normal operation Display 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 > 24.0V on a 24V Input system and not charging from (alternator) ‘CH3’ Icon Solid Charging from CH3 input (Start Battery / Alternator) ‘CH2’ Icon Flashing CH2 > 14.
Understanding The Function Key ‘MENU’, ‘SET’ And ‘SEL’ During Charger Setting CH1 - display is showing the charging battery info (charging status, voltage and current). CH2 or CH3 - When displayed symbol is solid this means the power is coming from the related channel and the other channel will be flashing if it is connected but not charging.
Button 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. Press once will temporary trigger on the display and it will automatically cycle through all three channels voltage, the software revision and then turn off.
Automatic Override Functions: When positive power is applied to the “Ignition Sense” terminal (do not connect to ground), it will force the charger to connect to CH3 as long as CH3 is within the voltage range >12.3V or 24.6V on a 24v input. Programming Your Charger Press and hold the key for longer than 3 seconds to enter charger setting mode and show function setting. Once new setting is done, press ‘MENU’ again for longer than 3 seconds to exit the charger setting mode.
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.
Procedure To Equalise Flooded Batteries DANGER Explosion Hazard And Risk Of Battery Damage. The battery generates explosive gases during equalisation. Follow all the battery safety precautions listed in the manual. When using the equalisation mode, the user has to be sure the battery connected to the battery charger is a flooded battery type. Equalizing a non-flooded battery may overcharge the battery and may cause the battery to explode. CAUTION Risk of battery and equipment damage.
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. Over Temperature Shutdown: When the charger senses the environmental temperature is above 60°C, the charger will shutdown.
Page 32 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 32.0V on a 24V input. This error will clear once the input has dropped below 15.5V on a 12V input or 31.0V on a 24V input. E02 CH3 Low Input Voltage Shutdown This means the unit has detected that the input from the Start/Alternator has gone below 10.5V on a 12V input or 21.0V on a 24V input. This error will clear once the input has risen above 13.
E08 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. A01 Over Temperature Warning When the charger’s internal temperature is > 60°C, the unit will shut down to protect itself.
