Enerdrive ePOWER DC2DC Battery Charger 40A

ePower DC to DC battery charger is smaller than our most compact AC BatteryCharger.

• 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 analternator linked to a battery; or via solar power with the in built MaximumPower Point Tracking (MPPT) Solar Controller. With two inputs available, themain/house battery will be charged from either the engine while underway, orvia the solar panels when stationary. The process to choose either engine orsolar is fully automatic and both functions are controlled from within theunit itself without the need for external relays.

During normal operation the ePOWER DC2DC Battery Charger will do a fullcharge cycle to float stage on the house battery bank with ability to chooseeither GEL, AGM, Flooded, Custom Programmable or Lithium. Once float stage isreached the charger transitions to a power supply mode to support any on-boardDC loads.

Multistage Charging Process

The ePOWER DC2DC Battery Charger is a fully automatic, set and forgetcharger. It is designed to quickly and accurately recharge your deep cyclebatteries utilising charger algorithms that help to maximise the life of yourspecialised deep cycle batteries.

The ePOWER DC2DC Battery Charger features multistage smart chargingtechnology that enables the charger to be connected to your battery bankpermanently. With the input of multiple sources, you can be assured ofcharging your batteries whenever underway; or when the sun is shining on yoursolar array.

As dictated by battery manufacturer’s recommendations, deep cycle batteriesrequire a multistage charge sequence for perfect, fast and accurate charging.The Enerdrive ePOWER DC2DC smart charger delivers three primary chargestages.

*Stage 1 *– Bulk or Boost charge; The battery is charged at full ratedoutput current of the charger until the battery reaches its final chargingvoltage, known as its absorption voltage. In this step, around 80% of thebattery is recovered as fast as possible.

*Stage 2 *– Absorption Charge; With the charger voltage held steady, theremaining 20% is replaced with the charger allowing the current to taper offas the battery approaches full charge.

*Stage 3 *– Float; Finally, in the float stage the charger voltage islowered and held at a constant and safe predetermined level. This prevents thebattery from being overcharged, yet allows the charger to supply enoughcurrent to make up for the self-discharge losses of the battery, whilesupporting any additional loads connected to the battery (such as DC lightingand refrigerators). This stage allows for the charger to be used as a DC powersupply.

Smart Charging Feature

The ePOWER DC2DC Battery Charger will regulate its output based on the loadsconnected to your battery bank. This function is important to maintain thelife of your battery bank as some battery chargers mistake loads for dischargeand continue to keep the batteries in the bulk or absorption stage forextended periods of time, which will damage the battery bank. The ePOWERDC2DC Battery Charger has two methods of load based regulation to ensure yourbattery charger transitions to float when it should do so.
