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.

  • 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 including a specific lithium charging profile
  • 30A 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 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 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 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 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+ Battery Charger has two methods of load based regulation to ensure your battery charger transitions to float when it should do so.

Circuit Protection (Circuit Breakers and Fuses) – Choosing an Amperage Rating – Generally, circuit protection devices are installed to protect the wiring from overheating during overloads or faults. The simplest approach for selecting a circuit protection device rating is to choose an amperage rating that is equal to or less than the current rating, ampacity of the wire. If the wire ampacity is significantly greater than the load current, as might be with small loads or with wiring of increased size to reduce voltage drop, then a range of circuit protection values between the load requirement and the wire ampacity may be acceptable. Larger ampacity values reduce the probability of nuisance failures and reduce fuse heating; smaller ampacity values provide more conservative protection for the wiring.

In some cases, a product manufacturer may recommend that a specific fuse or circuit breaker size should be used with the product. If that is the case, the wire to the product should be selected so that the wire ampacity exceeds the recommended rating, which will protect both the product and the wiring.
