12V DC to DC Battery Charger MPPT 20A Dual Battery Isolator Solar
During camping and off-roading, it is important to have a reliable auxiliary power source, but it might run out of power if no charger is installed. And this is where our DC to DC charger comes into play. Compared with traditional DC to DC charger, this device, which is suitable for AGM, Gel, calcium, LiON, VRLA and flooded battery. In addition to pulling power from alternator to charge auxiliary battery, it also has a built-in MPPT regulator to maximize energy absorption, thus reducing the load on your engine. Our charger also features pulse charging algorithm designed to recover your discharged battery. And over-charge, short circuit, over-temperature, thermal load, solar input overload, input/output reverse polarity protection have been integrated to offer an extra layer of protection.
Sturdy Construction: Sturdy aluminum housing is built to resist harsh conditions and quality wires are built for long last durability.
Dual Input: This Charger is designed to effectively pull power from solar panel (up to 20A) or vehicle’s alternator to charge your auxiliary battery.
Pulse Charging Algorithm: This algorithm is designed to select the optimum charge mode and revive your discharged battery.
Multi-Stage Charging: This charger integrates bulk charge, absorption and constant voltage (float) to improve efficiency and prolong battery’s lifespan.
Multi Battery Types: Compatible with AGM, Gel, calcium, Lion, VRLA and flooded lead acid battery.
Built-In MPPT Regulator: The regulator is designed to harvest up more energy from the solar panel, thus reducing the load on your engine.
Multiple Protection: It integrates over-charge, short circuit, over-temperature, thermal load, solar input overload, input/output reverse polarity protection.
Internal Temperature Monitoring: This mechanism can effectively protect the circuit board, thus prolong the lifespan of the charger.
Charger beeping in 2 situations:1. Reverse connection on the auxiliary battery —beeping only 2. Bad battery — beeping sound and flashing light on charger.
Superior Versatility: This DC to DC charger is ideal for 4WDs, caravans, RVs, trucks, campers, trailers, campervans, commercial vehicles and boats.
