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 chargers built-in MPPT controller adjusts voltage based on load, which is why tests may show readings below 14.2V. The MPPT controller optimizes the charging voltage to the most suitable level for the battery
Note: Unlike solar panels equipped with a PWM controller or without a controller, which have an open-circuit voltage of 18V-21V, the solar panel with a built-in MPPT controller has a voltage below 14.2V
12-Month After-Sales Service: The quality of your premium solar battery charger is guaranteed by CE/ROHS certifications and comes with a free lifetime technical support! If you have any questions, please contact us. Your suggestion helps us improve

3 LED Indicator Built-in Smart MPPT Controller 's upgraded built-in 3 LED Indicator, indicating battery charging status through three colors. The MPPT controller fast adjusts indicator lights in just 2 seconds under ample sunlight. With a 99% tracking efficiency, -MPPT significantly boosts solar charging efficiency.
3 Connection Methods Meet the Vast Majority of Scenes Important Safety Reminder
: To avoid any potential risks, never allow the positive and negative terminals of your battery to touch or connect. Although the likelihood of accidents is extremely low, it's imperative to exercise caution during the installation to prevent any unintended short-circuiting.
15W Solar Trickle Charger & Solar Battery Maintainer with IP65 Waterproof
Easy to Install for 12v batterys
Why does an MPPT controller improve the efficiency of solar panels?
An Maximum Power Point Tracking controller boosts solar panel efficiency by dynamically adjusting voltage and current. This ensures the system operates at its maximum power point, optimizing energy conversion efficiency under varying light conditions
What types of batteries can the solar battery charger maintain?
The solar battery charger is suitable for maintaining any rechargeable 12V batteries, including Lithium-ion, LiFePO4, Gel, AGM, etc.
Do I need to disconnect the solar panel while driving?
No, you don't need to disconnect. Our solar panel is equipped with overcharge protection circuitry built into the panel, which prevents backward charging.
Can the solar panel charge a car battery through a cigarette lighter when the car is off?
Yes, most cars can be charged with a cigarette lighter even when the engine is turned off. In cases where the cigarette lighter cannot be used for recharging, you can use alligator clips and cables to connect the solar panel directly to the battery.
Can I charge a battery that is almost dead with the solar battery charger?
It is a trickle charger that keeps the voltage from dropping or recharging the battery, but it is not a fast charger and cannot charge a dead battery. Please use the AC charger to fully charge the battery before using the solar panel.
