Two completely separate DC inputs for charging one house battery bank output from both the engine and the solar panel DC M6 screw connections that allow big battery cables to be connected to all sources For more precise battery charging, the charger includes a temperature sensor Fully programmable LCD display that indicates which source is charging the battery, as well as charger status, voltage, and amperage !!! FREE POSTAGE !!! 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. Enerdrive ePOWER DC2DC+ Battery Charger 40A ePower DC to DC battery charger is smaller than our most compact AC Battery Charger. 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+oC 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 Multistage Charging Process 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 ...
