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 our AC mains ePOWER battery charger. GEL, AGM, Flooded, Lithium and the ability to create  a full custom profile
  • Vehicle input allows for either 12 or 24v and a maximum solar input of 45V/800W
  • 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 

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.

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.

  • Temperature Sensor: Battery temperature sensor included with 3 meter cable.
  • 2 Year Warranty from an Australian company renowned for customer support.

Multistage Charging Process

The Enerdrive ePOWER 40A Battery Charger is a fully automatic, “set and forget” charger. It is designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. Multistage smart charging technology enables the charger to be connected to your battery banks permanently.
As dictated by battery manufacturer’s recommendations, batteries require a multistage charge sequence for perfect, fast and accurate charging. Our ePOWER multistage smart 40A battery charger deliver four 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 capacity is recovered as fast as possible.

Stage 2 - Absorption Charge

With the charger voltage held steady the remaining 20% is replaced allowing the current to drop as the battery approaches its 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 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.

Stage 4 – Maintenance

This stage is a regular timed “return to bulk” stage. After 7 days of constant operation in “float” the Enerdrive ePOWER Battery Charger will switch the charger from float to bulk to agitate the batteries electrolyte helping to provide an extended service life.

Charging Priority DiagramBank 1 PRIORITY – Charge Where You Need it Most

The ePOWER 40A Battery Charger delivers a priority charge to Bank 1, or your main house battery bank which allows the charger to get this bank recharged the quickest, then transition the cycle to the lesser bank 2 & 3 batteries.  The priority function also allows you to have a battery chemistry different to the other two, such as an AGM battery for house and lead calcium for your start banks. In the event that all 3 banks are in need of a charge, an over-ride function helps recover all 3 banks quickly and evenly before switching back to prioritise on Bank 1.

It’s All About Lithium

The recent advances in high capacity Lithium battery technology have seen the need to develop a battery charger suited to their needs. With most traditional ‘smart’ chargers their suitability to Lithium batteries is limited. Lithium batteries require a constant current / constant voltage charge algorithm and are unique in that almost every amp-hour of charge delivered by the charger is accepted as one amp hour into the battery, hence the need to deliver a constant current as long as possible.

The Enerdrive ePOWER charger can be programmed for Lithium batteries. This setting delivers the full rated output of the charger constantly with the charger switching to power supply mode once the voltage peak is met (indicating a full battery bank). The graph below shows the ePOWER charger algorithm perfectly supporting Lithium battery.

ePower Charge Algorithm Diagram

The Display Panel

The ePOWER 40A Battery Charger display gives you all the information you need for the operation of your charger. At a glance, key information such as charger amps, battery voltage and charge state continually alternate on the screen.When in float / power supply mode, the load amps are displayed so you can see exactly what the charger is doing. The display also allows you to program all settings of the charger, as well as activate the silent mode.
Silence when you need it – By pressing the “SEL” button for 5 seconds, the ePOWER Charger enters the ‘Silent’ mode that prohibits the fan from working. This ensures totally silent and safe operation at night, ideal if the charger is located close to your sleeping quarters. Silent mode limits current output to no more than 50%, and is programmed to remain on for 12 hours before automatically returning to a normal ‘fan-on & full output’ setting.
