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.
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.
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 utilizing charger algorithms that help to maximize the life of your specialized deep cycle batteries.
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.
Maximizing 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 optimized 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.
