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. *Vehicle Input limited to 50A, Vehicle Input voltage needs to be higher than output voltage to achieve 50A *Solar Input limited to 30A, Utilising a Higher voltage array will allow the output Amps to be greater than the 30A input limit\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"yikes-custom-woo-tab-title yikes-custom-woo-tab-title-features\"\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo totally independent DC Inputs for both engine and solar regulation charging one house battery bank output\u003c\/li\u003e\n\u003cli\u003eDC M6 screw terminals that will allow for large battery cable connection between all sources\u003c\/li\u003e\n\u003cli\u003eA dedicated Maximum Power Point (MPPT) solar regulator\u003c\/li\u003e\n\u003cli\u003eThe same battery algorithms as included in our AC mains battery 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.\u003c\/p\u003e\n\u003cp\u003eEnerdrive | Dometic 12V 40A+ (up to 50A*) DC-DC 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.\u003c\/p\u003e\n\u003cp\u003eAs dictated by battery manufacturer’s recommendations, deep cycle batteries require a multistage charge sequence for perfect, fast and accurate charging. The Enerdrive | Dometic DC2DC 40A+ smart charger delivers three primary charge stages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStage 1\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStage 2\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStage 3\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– 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.\u003c\/p\u003e\n\u003ch3\u003eSmart Charging Feature\u003c\/h3\u003e\n\u003cp\u003eThe Enerdrive | Dometic 12V 40A+ (up to 50A*) DC-DC 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 Enerdrive | Dometic 12V 40A+ (up to 50A*) DC-DC Battery Charger has two methods of load based regulation to ensure your battery charger transitions to float when it should do so.\u003c\/p\u003e\n\u003cp\u003e\u003cimg decoding=\"async\" class=\"wp-image-17021 alignleft\" src=\"https:\/\/enerdrive.com.au\/wp-content\/uploads\/2018\/10\/epower-charger-tempsens-300x300.png\"
