- Innovative MPPT Built-in Controller: Maximizes charging efficiency with up to 99% conversion. The 15W MPPT charger adjusts power based on sunlight intensity, ensuring superior performance even on cloudy days compared to non-MPPT chargers
- Smart Maximum Power Point Tracking: POWOXI-MPPT optimizes energy extraction for changing conditions, ensuring efficient solar power harnessing by dynamically adjusting to the environment for maximum output
- Comprehensive Battery Protection: MPPT controllers include a float/maintenance stage to prevent overcharging, extending battery life and improving energy efficiency. Compatible with various 12V batteries, including gel, AGM, SLA, VRLA, and lithium-ion
- 3 LED Indicator Lights: The solar charger has three 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 and Long-lasting Materials: Made with PC+ABS+Tempered glass, these solar panels withstand -40 to 137°C and are IP65 waterproof, enduring heavy rain, ABS+PC frames are stronger than flexible panels and won't damage car paint like aluminum frames
- Voltage Detection Statement: The solar battery charger built-in MPPT controller adjusts voltage based on the load, so voltage tests may show below 14V. Once connected to a battery, the open-circuit charging voltage stays within 21V
