4. UNDERSTANDING THE UNIT
The Enerdrive ePOWER DC2DC 24V 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. The process to choose either engine or
solar is fully automatic and both functions are controlled from within the unit itself without
the need for external relays.
During normal operation the ePOWER DC2DC 24V Battery Charger will do a full charge cycle
to oat stage on the house battery bank with ability to choose either GEL, AGM, Flooded,
Custom Programmable or Lithium. Once oat stage is reached the charger transitions to a
power supply mode to support on-board DC loads.
Multistage Charging Process - GEL, AGM, Flooded & Program Modes
The ePOWER DC2DC 24V Battery Charger is a fully automatic, set and forget charger. It is
designed to quickly and accurately recharge your deep cycle batteries utilising charger
algorithms that help to maximise the life of your specialised deep cycle batteries.
The ePOWER DC2DC 24V Battery Charger features multistage smart charging technology that
enables the charger to be connected to your battery banks permanently. With the input of
multiple sources, you can be assured of charging your batteries whenever underway; or when
the sun is shining on your solar array.
As dictated by battery manufacturer’s recommendations, deep cycle batteries require a
multistage charge sequence for perfect, fast and accurate charging. The Enerdrive ePOWER
DC2DC 24V smart charger delivers three primary charge stages.
Stage 1 – Bulk or Boost charge; The battery is charged up to the full rated output current of
the charger until the battery reaches its nal charging voltage, known as its absorption voltage.
In this step, around 80% of the battery is recovered as fast as possible.
Stage 2 – Absorption Charge; With the charger voltage held steady, the remaining 20% is
replaced with the charger allowing the current to taper o as the battery approaches full charge.
Stage 3 – Float; Finally, in the oat stage the charger voltage is lowered and held at a constant
and safe predetermined level. This prevents the battery from being overcharged, yet allows the
charger to supply enough current to make up for the self-discharge losses of the battery, while
supporting additional loads connected to the battery (such as DC lighting and refrigerators).
This stage allows for the charger to be used as a DC power supply.
Lithium Charging Process
The ePOWER DC2DC 24V charger has a specic charging prole for Lithium batteries. It has
its own charging voltage and current settings that needs to be set by the user. It also requires
the user to set the charger termination current (“L“ setting). Once the user dened charge
voltage is reached, the charger will start reducing the current output and the charging process
will terminate when the charging current drops to the set termination current. This can take
anywhere between 3 to 15 minutes. The unit will then act as a power supply to support
Enerdrive ePOWER DC2DC 24V Battery Charger Owners Manual (Rev. 1.5) www.enerdrive.com.au
Page 8 Page 9

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.
Smart Charging Feature
The ePOWER DC2DC 24V 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.
The ePOWER DC2DC 24V Battery Charger has two methods of load based regulation to ensure
your battery charger transitions to oat when it should do so.

Note 3: Charger is acting as a power supply with selected constant output voltage and
preset maximum output current.
NOTE: The equalisation function although included in the ePOWER DC2DC 24V 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.
Battery Bank Size Recommendation
The battery charging current rating is based on the battery size. The battery bank should
meet the minimum Ah rating as shown. If a smaller size battery bank is used, set the current
rating to a lower value to match with the battery bank size. Normally, the minimum battery
bank capacity is based on a C5 rating of the battery for charging.

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.
Note B:
When the unit has activated the battery charging process using the ignition sense terminal
(Priority Mode) or using the Manual Override through the unit setting, the input voltage
specication is reduced. It has the same charging process but with a Low Start-Up Voltage
set to >12.3Vdc 12V system (>24.6V on a 24V system). This feature is designed to be used for
vehicles tted with “Smart Alternators”.
If the measured voltage on CH3 is <12.0 Vdc (<24Vdc on a 24V system), the unit will disconnect
from the vehicle source and switch back to charge from CH2 (solar if installed) until the CH3
voltage returns to >12.3Vdc on a 12V System (>24.6V on a 24V system).
The Low Under Voltage Recovery Voltage is set to > 12V (from 12.8V) on a 12V system and
> 24V (from 26.4V) on a 24V system. During the 5 second rest period, if the input voltage
returns above 12V/24V, it will continue the charging process and if the input voltage does
not return to > 12V/24V, it will switch back to charge from the Solar - CH2 (if connected) until
the Start - CH3 input has returned to the Low Start-Up voltage of 12.3V on a 12V system and
24.6V on a 24V system.
Note C:
During the 3 minute charging process, if the measured terminal voltage drops below the
Under Voltage de-rated limit (11.5V for a 12V system, 23V for a 24V system), the charger will
start to de-rate the charger current. This function is used to compensate the use of long
or thin cable between the Input Battery and the unit terminals. If the voltage continues to
drop to below the Under Voltage Shutdown limit of (10.5V for a 12V system and 21V for a
24V system), the charging process will terminate and the unit will switch back to charge from
CH2 (solar if installed). It will only switch back to CH3 if the CH3 voltage returns to 13.2V
(12.3v with ignition sense connected) on a 12V system and 26.4V (24.6V with ignition sense
connected) on a 24V system.
Note D:
The CH3 DC Input (Battery Input) can accept a 12V or 24V battery with an alternator system.
When the unit is rst connected, the unit will measure the input voltage. If the voltage is
>17V, it will assume it is connected to a 24V Input Battery/Alternator system. If the voltage
detect is < 17V, it will assume it is connected to a 12V Input Battery/Alternator system. Once
detected, it will store this into the microprocessor and it will only be erased if the Input
battery is disconnected or if the measured Input Voltage drops to < 7Vdc.
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

Note A:
When the battery is charging through CH3 with normal operation (not through Ignition
or override setting), the charger will charge for 3 minutes, it will then rest for 5 seconds to
verify the Input voltage.
During the 5 seconds rest period, if the measured voltage is >12.8Vdc on a 12V System
(>25.6Vdc on a 24V system), the unit will continue the charging cycle through CH3.
If the measured voltage on CH3 is <12.8Vdc (<25.6Vdc on a 24V system), the unit will
disconnect from the vehicle source and switch back to charge from CH2 (solar if installed)
until the CH3 voltage returns to >13.2Vdc on a 12V System (>26.4V on a 24V system).
Also, during the 3 minutes charging process, if the measured terminal voltage drops below
<11.5V for a 12V system, (<23V for a 24V system), the charger will start to derate the output

an economic decision. You can install more power than the controller can use and this will
contribute to better power availability. Enerdrive suggest a total maximum overdrive of
20% (total 1000w). On cloudy (or intermittent sunny) days there will be little or no power
shaving and the extra power will serve the battery well with more energy harvest earlier
and later in the day.
Maximising your Solar Harvest using the DC2DC 24V
The Solar Input on the DC2DC 24V 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
15amps @ 14.4Vdc output.
Panel Array Rated Wattage & Volts Open Circuit rating Estimated DC Amps
Output (## See Below)
1 150watt @ 20Voc 150watts 4 Amps
1 200watt @ 43Voc 200watts 5 Amps
2 150watt @ 20Voc 300watts 8 Amps

5 150watt @ 20Voc 1000watts Not Recommended
5 200watt @ 43Voc 1000watts 30 Amps**
* Maximum achievable output on the DC2DC 24V unit when using 20Voc Solar Panels will
be the approximately 15amps.
** Maximum achievable output on the DC2DC 24V unit when using 43Voc Solar Panels will
be the approximately 30amps.
## IMPORTANT NOTE: Estimated Amps Output is quoted based upon PERFECT Solar
conditions including Sun Angle, Panel Mounting angle and Orientation to the sun. It
needs to be noted that panel performance alters dramatically between Summer and
Winter periods and actual performance may be impossible to predict.

Press the key to view other available settings.
Understanding the Two-Stage (Mode 2) Charging
(Default setting is 3)
The DC2DC 24V can be set to act as a 2 stage charger (Bulk/Float). Certain applications may
require a 2 stage charge process and by setting this option, the DC2DC 24V unit will act
accordingly to meet this requirement.
During the Bulk stage, the battery accepts the maximum constant current from the charger.
In Float stage, the charger continuously produces a lower constant oat voltage to maintain
the battery in a fully charged stage.
Understanding The Three-Stage (Mode 3) Charging
The Three-Stage Charging (Mode 3) has a Bulk/Absorption/Float sequence. During the Bulk
stage, the battery accepts the maximum constant current from the charger. In the Absorption
stage, the battery voltage is held to constant voltage and the charging current will slowly
reduce. In Float stage, the charger continuously produces lower constant oat voltage to
fully top up and maintain the battery in a fully charged stage.
The charger will automatically restart the full charging cycle if it senses the battery bank is
discharged to lower than 25.0V for lead acid batteries and 26.6V for lithium batteries.
Understanding The Battery Temperature Functions
The Battery Temperature Sensor is included with the charger to protect your battery and
provide better charging voltage accuracy.
When the battery temperature sensor output is used, it is highly recommended to be
installed on the main battery bank at the negative terminal. The sensor senses the battery
Enerdrive ePOWER DC2DC 24V Battery Charger Owners Manual (Rev. 1.5) www.enerdrive.com.au
Page 26 Page 27

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.
Temperature Setting Recommended
Battery Temperature Battery Type

Note: The above voltage compensation will only work with the supplied Battery Temperature Sensor tted which
will override the unit temperatures’ (Lo, Nor, Hi) setting. If using lithium batteries, leave temp setting “NOR“ (Normal)
and leave temp sensor disconnected.
Procedure To Set Or View Charger Setting
Follow the procedure or sequence in Appendix A1 and A2 (see back of this manual) to set
or view the charger setting.
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. Equalizing a non-ooded battery may
overcharge the battery and may cause the battery to explode.
CAUTION
Risk of battery and equipment damage.
Only Flooded lead-acid can be equalised. Consult your battery manufacturer or read the
battery manual when you try to equalise your batteries.
Disconnect any DC load connected to the battery, as during equalise mode, the charger will
produce 31.0V to the batteries. You must monitor the battery specic gravity throughout
the equalisation process to determine the end of the equalising cycle.
Before setting the equalisation mode, please be sure the battery is a ooded battery type.
When the battery equalisation has started, the charger will automatically fully charge the
battery bank and will then follow with 1 hour of equalisation. Check the battery electrolyte
level during the equalisation period. If necessary, rell with distilled water only. All cells
should have similar electrolyte levels. If distilled water is added, batteries must undergo a
complete charge cycle. The charger cannot determine when to terminate the equalisation
of the battery, a one hour time-out is set and this is used as a safety feature to require the
user to continually re-activate it as necessary after checking batteries manually.
Use the following procedure to setup the charger for battery
equalisation.
With Flooded Battery Type setting, Press and Hold Button “SET“ and “SEL“ together for
more than 5 seconds. This will force the charger to go into to Equalized mode and it will
start equalizing the ooded battery. Please note the battery mode setting has to be set to
‘Flooded’ battery type in-order to have this function activated.

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. It will recover automatically when the environmental temperature drops to
below 45°C.
Battery Reverse Polarity:
When a reverse polarity is connected to the battery bank, “Error Code E08” on the display
will appear.
Charging A Flat Battery
The charger is designed to charge batteries with terminal voltage greater than 17.0Vdc.
Re-charging a at battery requires extreme care and attention. It is best to re-charge using
short frequent cycles rather than one long bulk cycle. Battery damage or failure may occur
if the battery is discharged so deeply.
Understanding The Display Codes
Codes will show on the display when either a function or internal warning / fault, such as
high internal temperature or DC out of range is detected and the charger may shut down to
protect itself until the fault has cleared. See table description below for more information.
Code Description
The charger is in Bulk Charging Mode
Bulk or Boost charge; The battery is charged at the set rated output current of the charger until the battery reaches its nal
charging voltage, known as its absorption voltage. In this step, around 80% of the battery is recovered as fast as possible.
The Charger is in Absorption Charging Mode
Absorption Charge; With the charger voltage held steady, the remaining 20% is replaced with the charger allowing
the current to taper o as the battery approaches full charge.
The charger is in Float Charging & Power Supply Mode
Float; Finally, in the oat stage the charger voltage is lowered and held at a constant and safe predetermined level.
This prevents the battery from being overcharged, yet allows the charger to supply enough current to make up for the
self-discharge losses of the battery, while supporting additional loads connected to the battery (such as DC lighting and
refrigerators). This stage allows for the charger to be used as a DC power supply.
CH3 Input Voltage Check
This will display for 5 seconds every 3 minutes while charging from the alternator input (CH3) and is normal operation
when the charger is checking the under voltage recovery limit (see page 18 for details).
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 13.2V on a 12V input or 26.4V on a 24V input.
If you have this error:
•Check that the voltage of your Start Battery is above 13.2V on a 12V input or 26.4V on a 24V input.
•Check that you have not left the “Priority” (Override) feature activated (Manual or Auto)
•Check that the battery cable from the Start Battery is correctly sized.
•Check you don’t have a loose terminal or blown fuse.
E03
CH2 High Input Voltage Shutdown
This means the unit has detected the input from the solar has gone above 45.0V. This error will clear once the input has
dropped below 44.0V.
If you have this error:
•Check the specication of your panels – the Volts Open Circuit (VOC) should not exceed 45VOC
•Make sure the solar panels have not been connected in series as this will increase the VOC voltage of the panel array.
Please Note: Maximum solar VOC input must not exceed 45VOC or damage to the unit will occur.
E04
CH2 Low Input Voltage Shutdown
This means the unit has detected the input from the Solar Array cannot sustain voltage above 14.5v.
If you have this error:
•Check that you are not in a low light/non direct sunlight situation i.e. Early morning / late afternoon.
•This may also happen if your solar panels are inside in a shed with a skylight or Hi Bay Lights running or outside under
Flood Lights.
If you nd this is happening with your unit when stored, we recommend tting a DC Breaker to the output of the DC2DC
24V and turning it o when the unit is not in use/storage.
E05
CH1 High Input Voltage Shutdown
This means the unit has detected that the Main/House battery has gone above 32.0V. This error will clear once the input
has dropped below 31.0V.
This may be due to charging from another source. i.e. Another solar controller or AC battery charger.
E06
Over Temperature Shutdown
When the charger senses the environmental temperature above 60°C, the charger will
Shut down. It will recover automatically when the environmental temperature drops below 45°C.
•Check to make sure the fan is working.
•Make sure the unit has good ventilation.
E07
BTS Over Temperature Shutdown
This means the units Battery Temp Sensor has detected that the batteries are too hot and has shut down to not over
charge the batteries.
If this occurs, take care and check the temperature of the batteries.
•If the Batteries are Hot –you may have a dropped cell or faulty battery. Stop all charging and see your local battery
shop to get your batteries tested.
•If the Batteries/Terminals are still cool or only warm, you may have a bad temp sensor. Unplug the temp sensor and
call Enerdrive.

Page 30 Page 31

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. The unit will return back to
normal charging once the internal temperature is < 58°C
•Check to make sure the fan is working.
•Make sure the unit has good ventilation.
A02
BTS High Temperature Warning
When the battery temperature sensor is > 58°C, the unit will shut down to protect the batteries. The unit will return
back to normal charging once the battery temperature sensor is < 56°C.
•Check to make sure the batteries are not hot.
•Make sure the batteries have good ventilation.
