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.
• 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 the 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

What is the purpose of a DCDC charger?
a DCDC chargers purpose is to provide the correct level of charge to your battery in a fast, safe and regulated way. This Enerdrive DCDC charger will take charge from both your alternator or from your solar panels via the in-built MPPT solar controller, this means you are able to charge your batteries on the road while driving, as well as when you're parked up.
What vehicles can this unit be installed into?
This unit is amongst some of the most popular choices when it comes to DCDC charging in vehicles such as 4WD's, Caravans, Camper trailers, boats, or any recreational/commercial vehicle.
Do I need circuit protection for this DCDC charger?
Yes, the size of the circuit breakers will depend if you are applying the unit to a 12V alternator or a 24V alternator.
If you are connecting to a 12V alternator you will need a 40AMP circuit breaker on the input and a 40AMP circuit breaker on the output.
If you are connecting to a 24V alternator you will need a 70AMP circuit breaker on the input and a 40AMP circuit breaker on the output
We recommend the AllSpark Circuit Breaker as it allows you to isolate via the push-to-trip function, and also can be re-set should an overload event occur (without blowing a fuse, which can be costly and inconvenient to replace).
What size battery is this suitable for?
This unit is adjustable from 5 to 50Amps, so will suit any size battery bank. Keep in mind that the larger the battery/bank the slower they will charge, and be sure to check the charging rate on smaller batteries so as not to charge faster than the recommended rate. Also you will need to ensure that your vehicles alternator is able to handle the current draw required.
