WARNING Explosion Hazard! DO NOT use the Enerdrive DC2DC+ Battery Charger in the vicinity of ammable fumes or gases (such as gas bottles). AVOID covering the ventilation openings. Always operate unit in an open and well ventilated area. Prolonged contact to high heat or freezing temperatures will decrease the working life of the unit.
3. PRODUCT DESCRIPTION The Enerdrive DC2DC+ Battery Charger is a multistage, multi-input battery charger to charge di erent 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 DC2DC+ Battery Charger 1 x Battery Temperature Sensor 7.5 Meter Cable)
4. UNDERSTANDING THE UNIT The Enerdrive 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.
Smart Charging Feature The DC2DC+ Battery Charger will regulate its output based on the loads connected to your battery banks. This function is important to maintain the life of your battery banks as some battery chargers mistake loads for discharge and continue to keep the batteries in the bulk or absorption stage for extended periods of time, which will damage the battery bank.

NOTE: The equalisation function although included in the DC2DC+ will rarely be used. To activate, the battery bank must be in oat, 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.
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. •...
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.
Recommended Fuse Protection 70amp Fuse or Circuit Breaker no greater than 20cm from source battery. From Alternator Battery PLEASE NOTE: Automatic re-settable circuit breakers are NOT recommended. Fusing recommended no greater than 20cm from input to DC2DC+ From Solar Panels Charger.
Battery Wiring (Towing Applications): For Towed Applications i.e. Caravans, Camper Trailers Please NOTE The negative cable from the start battery must be carried to the DC2DC input terminal for correct operation in a towed application. (Optional Ignition - On) (Voltage Sense Override) Fuse Size 1A Temp Sensor Cable (Included)
Battery Wiring (Vehicle & Marine Applications): For In Vehicle & Marine Installation. i.e. Motorhomes, 4WD’s & Trucks. Please NOTE Vehicles with a Smart alternator, the Negative cable must be connected to the vehicle side of the Battery Sense Module. (Optional Ignition - On) (Voltage Sense Override) Fuse Size 1A Temp Sensor Cable...
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 o 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.
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 MPPT type ( approx.
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 Charging Status, Voltage, Current CH2 & CH3 Voltage Fault/Warning Error code E01-08, Warning A01-02 CH3 > 12.0V on a 12V Input system ‘CH3’...
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 ashing 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 •...
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.
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. Voltage adjustment Recommended Temperature Setting Battery Type from 25°C normal Battery Temperature setting GEL, Flooded + 0.675 V Low (Lo)
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 ooded battery type.
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.

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. 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.

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 >...
