Solar Charger Controller with MPPT for LiFePO4 & AGM Batteries

[Multi-input Efficient Charging] The ECO-WORTHY DC-DC charger features a built-in solar charge controller, offering a 2-in-1 charging solution with both generator starting battery input and solar panel input. This allows the charger to accommodate different types of batteries, including AGM/GEL, lead acid, lithium, and calcium.

[Intelligent MPPT Charging] Boasting an IP65 waterproof rating, the charger utilizes a MPPT (Maximum Power Point Tracking) solar intelligent control management system. This system records user charging habits, optimizing the charging process for maximum efficiency.

[One-Way Charging] Designed with enhanced safety in mind, the charger features isolation for primary and secondary batteries. This one-way charging mechanism prevents reverse charging and power consumption, protecting the house battery from unwanted discharge.

[Comprehensive Protection Measures] To ensure extended battery lifespan, the charger incorporates several comprehensive protection features. These include engine start battery low-voltage protection, as well as overcharging and short-circuit safeguards.

[Easy to use] For seamless installation and operation, the charger offers clearly labeled wiring connections for solar panels, alternator, and batteries. Indicator lights provide visual confirmation of normal charging status, allowing for easy identification of any abnormal connections.

How does MPPT charging work? The DC-DC charger adopts the maximum power point tracking (MPPT) algorithm, ensuring that the charger converts most of the available energy by locking onto the maximum power point.

Does it support input from solar panels and starter battery at the same time? Yes, the charger is capable of handling multiple input sources. Alternator input requires an input voltage range of 12.4-16V from the starter battery, while solar charging requires an input of 16-25V from the solar panel. When both solar and alternator inputs meet the charging conditions, the charger will prioritize the alternator input.

What is a DC-DC charger? The DC-DC battery charger is installed between the starter battery and the leisure battery, or between the solar panel and the leisure battery. It functions to charge the leisure battery by drawing power from the vehicle's alternator or a solar panel.
