ECO-WORTHY 12V 40A DC to DC Charger with Solar Charge Controller

The DC-DC battery charger is installed between the starter battery and the leisure battery, or between the solar panel and the leisure battery, allowing you to charge the leisure battery by pulling power from the vehicle's alternator or solar panel. The DC-DC charger adopts maximum power point tracking technology (MPPT) algorithm to ensure that the charger converts most of the energy by locking to the maximum power point.

This charger supports input from both solar panels and the starter battery simultaneously. The alternator input requires an input of 12.4-16V from the starter battery, while the solar charging requires an input of 16-25V from the solar panel. The charger will choose the alternator input when both solar and alternator inputs meet the charging condition.

[Multi-input Efficient Charging] The ECO-WORTHY DC-DC charger features a built-in solar charge controller, allowing it to function as a 2-in-1 charger with both generator starting battery input and solar panel input. This versatile charger can charge different types of batteries, including AGM/GEL, lead acid, lithium, and calcium batteries.

[Intelligent MPPT Charging] The IP65 waterproof charger utilizes an MPPT solar intelligent control management system that includes a charging memory feature to record user charging habits, ensuring efficient and tailored charging.

[One-Way Charging] Enhanced safety is provided through isolation for primary and secondary batteries, preventing power loss from the house battery. The one-way charging feature prevents reverse charging and power consumption.

[Comprehensive Protection Measures] The charger incorporates engine start battery low-voltage protection, as well as overcharging and short-circuit protection, to extend the lifespan of your batteries.

[Easy to use] The charger features clearly labeled wiring for solar panels, alternator, and battery, along with indicator lights for normal charging connections, ensuring easy identification of any abnormal connections.
