Product Description

Enerdrive ePOWER 12V 40A DC to DC Battery Charger designed to meet the rugged demands of Australian conditions and delivering multiple source charging for DC systems.

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 main/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+ Battery Charger will do a full charge cycle to float stage on the house battery bank with ability to choose either GEL, AGM, Flooded, Custom Programmable or Lithium. Once float stage is reached the charger transitions to a power supply mode to support any on-board DC loads.

12V 40A DC2DC Battery Charger Features

  • Two totally independent DC Inputs for both engine and solar regulation charging one house battery bank output
  • DC M6 screw terminals that will allow for large battery cable connection between all sources
  • A dedicated Maximum Power Point (MPPT) solar regulator
  • The same battery algorithms as included in Enerdrives AC mains ePOWER battery charger including a specific lithium charging profile
  • 40A output up to 40+°C with thermo controlled fan cooling
  • Fully programmable LCD display to show which source is charging the battery along with charger status, voltage and amperage
  • Temperature sensor included in charger for more accurate battery charging

PRO TIPS: 

  • Common accessories to go with this DC to DC charger are the 60Amp & 70Amp breakers, also the 3 pre-wired & fused charging cables. These are available in the Accessory List above to add as optional extras, please see the product manual & drawings for the connection.
  • You will require a ratchet crimping tool for this cable kit. PLEASE CLICK HERE to find our tool range.

Multistage Charging Process

The ePOWER DC2DC+ 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+ Battery Charger features multistage smart charging technology that enables the charger to be connected to your battery bank 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+ smart charger delivers three primary charge stages.

Stage 1 – Bulk or Boost charge; The battery is charged at full rated output current of the charger until the battery reaches its final 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 off as the battery approaches full charge.

Stage 3 – Float; Finally, in the float 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 any 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.

Smart Charging Feature

The ePOWER DC2DC+ Battery Charger will regulate its output based on the loads connected to your battery bank. This function is important to maintain the life of your battery bank 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+ Battery Charger has two methods of load based regulation to ensure your battery charger transitions to float when it should do so.

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 approx 35amps @ 14.4Vdc.

Panel Array Rated Wattage & Volts Open Circuit Rating Estimated DC Amps Output (## See Below)
1 150watt @ 20Voc 150watts 10
1 200watt @ 43Voc 200watts 13
2 150watt @ 20Voc 300watts 21
2 200watt @ 43Voc 400watts 27
3 150watt @ 20Voc 450watts 31
3 200watt @ 43Voc 600watts 42
4 150watt @ 20Voc 600watts 35*
4 200watt @ 43Voc 800watts 47**
5 150watt @ 20Voc 1000watts Not Recommend
5 200watt @ 43Voc 1000watts Not Recommend

* Maximum achievable output on the DC2DC+ unit when using 20Voc Solar Panels will be the approx 35amps. ** Maximum achievable output on the DC2DC+ unit when using 43Voc Solar Panels will be the approx 47amps.

## 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.

Product Faqs

Ask a Question

  • Q:HI, is the latest model that will charge up to 50amps?Cheers
    A:

    Hi Marc,

    Yes this is the latest model from Enerdrive.

    It does have the capabilities of charging up to 50A!

  • Q:Hi, just wondering if you are able to select which the charger will draw from first? Eg. Solar over alternator. If so will it still use the alternator if more is needed?
    A:

    Hi Isaac,

    There are provisions to manually override the charging source from alternator to solar.

    However Enerdrive state: If Manual Override Mode is used and left on there is a risk of flattening the start battery. The preferred method is to use the automatic override method by connecting the ignition source to the ignition terminal of the DC2DC+ charger.

  • Q:Can I use the dc2dc charger with a 600 watt wind turbine. I have a battery bank of 4 120 AH 12 volt batteries.
    A:

    Hi There,

    This charger is not suitable for use with wind turbines sorry.

  • Q:What size battery charger do I need for my lead acid battery I have in my camper?
    A:

    A good battery charger rule of thumb for charging a lead acid battery, is using a charger with output current (amps) of 10-20% of the battery total stored capacity (Ah).

    So, for example if the battery is 12V 100Ah, the charger need to be minimum of 10A and maximum of 20A.  Often splitting the difference at 15% (so a 12V ~15A charger) is a good option. Happy charging!

  • Q:What is the maximum amount of solar wattage i can use with the endrive ePower 12v 40 Adc-dc charger?
    A:

    Hi There

    Enerdrive state the following:

    *Note: The recommended maximum solar wattage input for the DC2DC+ Charger is 500w. You can however “overdrive” the MPPT controller. Please note that doing this is partially 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 600w). 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

  • Q:Hi,Just wondering what the IP rating of these are.eg. IP67ThanksGrant
    A:

    Hi There,

    These chargers are not IP rated sorry. They are designed to be fit inside the vehicle with no possibility of coming in contact with water.

  • Q:is there a remote head to use with the Enerdrive EN3DC40+ 40A DC2DC charger
    A:

    Hi There,

    Currently there is not a remote option for the Enerdrive EN3DC40+ sorry.

  • Q:Does the temperature compensation sensor work when the unit is operated with custom charge settings?
    A:

    Hi There,

    Yes it doe The only setting which renders the temp sensor unusable is Lithium mode. This is ok because the temp variables allowable for lithium is such that the lithium algorithm is not effected by it.

     

  • Q: Does it automatically choose 24v when attached to a 24v system or does it manually have to be switched?
    A:

    Hi There,

    You do not need to manually set that your system is 24V.

    Provided the voltage from the system meets the 24V requirements for the charger, it will do all the work.

    You can read the manual for the charger here:

    https://mygenerator.com.au/media/DC2DC-PLUS-User-Manual-WEB-1.0.pdf

  • Q:LiFePo4 manufacturers suggest that the dc/dc charger output should be 20% of the battery's Ah capacity. This suggests that the charger is unsuitable for a battery less than 200Ah. can the output be limited in anyay to 20A / 30A etc?
    A:

    Hi There,

    The Enerdrive 40A charger output can be programmed from 5A - 50A depending on your battery size.

  • Q:If the charger is mounted in a camper or can, what would the result of NOT connecting the ignition wire?
    A:

    Hi There,

    Please refer to the notes on page 21, and 22 for details regarding ingition sensing.

    https://mygenerator.com.au/media/DC2DC-PLUS-User-Manual-WEB-1.0.pdf

  • Q:hi guys ....just wondering if the charger will work if i run my 400watt airgen to the starting battery first then run the charger input wires to start battery,,to be able to charge a house battery(300amp) without starting the engine TIA roger
    A:

    Hi There,

    We would recommend clarifying this with Enerdrive.

    You can contact them on: 1300 851 535

  • Q:If I have a 240volt charger also connected to the batteries and I plug it in to keep everything top up when in my shed will this hurt the DCDC charger? Or do I need to disconnect it?
    A:

    Hi There

    Provided you are not trying to charge with both sources at the same time there should be no issue whatsoever!

    A lot of folks do this with their caravans to prevent the batteries going dead when in storage.

  • Q:If I have a 100ah AGM in my camper and a 200w solar blanket will this 40amp DC to DC be okay to use?I plan to upgrade to a lithium battery in the future so want to install something for now and when I get the lithium battery.
    A:

    Hi There,

    The Enerdrive 40A DC DC charger will certainly do the job for your current installation, and will also work for your future lithium battery installation.

    They are a great charger, and very easy to install.

  • Q:Hello,Can I run 2 seperate solar sources into the unit?I'm looking at a fixed 180w panel on the roof, and then plugging an additioanl 200w blanket into it when I stop.Alan
    A:

    Hi Alan,

    Yes you cold certainly do that. Ideally you would want to set up an external Anderson plug to connect the solar blanket into that then runs back to the charger.

  • Q:Am I able to run 240v power into this unit when my 4wd is parked up to keep my 12v system in peak condition?
    A:

    Hi There,

    The Enerdrive DC to DC charger does not have mains power input.

    To charge your system from mains power you would require a 240V charger.

    You can find our range of 240V chargers at the following link:

     

    https://www.mygenerator.com.au/ac-to-dc-battery-chargers.html

  • Q:Can it run from the solar & altenator simuitaneousl with a preferance to solar first.
    A:

    Hi There,

    The EN3DC40+ will not charge from the alternator, and solar at the same time.

    It will preference the alternator when the vehicle is running. To switch to solar you would need to change the charger setting to solar.

  • Q:Would you recommend having a seperate mppt solar regulator to the dc - dc charger so that a secondary battery can be charged by both inputs at the same time or is a dc - dc charger with mpg input good enough to do the job
    A:

    Hi There

    From our experience we do not see the need for an additional MPPT for charging a second battery at the same itme as charging from the vehicles alternator.

    The Enerdrive EN3DC40+ can output up to 50A @ 12V which is a lot of charging power.

  • Q:Does this charher have functions to communitcate with a smart alentator
    A:

    Hi There

    The Enerdrive DC DC charger is designed to work with smart alternators without any charging issues.
