Innovative built-in MPPT controller maximizes charging efficiency with up to 99% conversion. It adjusts power based on sunlight intensity, ensuring better performance even on cloudy days.

Smart MPPT tracking optimizes energy extraction for changing conditions, ensuring efficient solar power harnessing by dynamically adjusting to the environment for maximum output.

Comprehensive battery protection includes a float/maintenance stage to prevent overcharging, extending battery life and improving energy efficiency. It's compatible with various 12V batteries, including gel, AGM, SLA, VRLA, and lithium-ion.

The solar charger has three LED indicator lights: blue for sunlight reception, red for charging, and green for a fully charged battery. The MPPT takes 2 seconds for calculation and LED status updates.

Robust materials, including PC+ABS+Tempered glass, ensure the solar panels withstand -40 to 137°C and are IP65 waterproof, enduring heavy rain. The frames are stronger than flexible panels and won't damage car paint.

The built-in MPPT controller adjusts voltage based on load, which may show readings below 14.2V during tests. It optimizes the charging voltage to the most suitable level for the battery.

The solar panel with a built-in MPPT controller has a voltage below 14.2V, unlike those with a PWM controller or no controller, which have an open-circuit voltage of 18V-21V.

We offer 12-month after-sales service, backed by CE/ROHS certifications and free lifetime technical support.
