Thank you for supporting and choosing POWOXI. ——- Upgraded solar battery charger with built-in MPPT controller from POWOXI POWOXI has undergone a comprehensive upgrade with its built-in MPPT controller solar battery charger. The integrated MPPT controller not only enhances the efficiency of solar panel charging but also eliminates the cumbersome process of serial controller connection, Making charging simple! 3 LED Indicator Built-in Smart MPPT Controller POWOXI’s upgraded built-in 3 LED Indicator, indicates 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, POWOXI-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. 【Innovative Upgrade MPPT Built-in Controller】Make charging high tracking efficiency and conversion efficiency of up to 99%, The MPPT solar battery charger automatically adjusts the most efficient power to charge the battery according to the sunlight intensity, This is an innovative technology that allows the solar panels to perform better than solar chargers without MPPT controllers even on cloudy days. 【Smart Maximum Power Point Tracking】POWOXI-MPPT employs a approach tailored for variable, strategically optimizing energy extraction to adapt seamlessly to changing conditions. This technique ensures the efficient harnessing of solar power, dynamically adjusting to varying environmental to maximize overall energy output. 【Comprehensive battery protection】MPPT controllers have a float/maintenance stage to keep batteries charged without overdoing it. This smart feature extends battery life and improves energy efficiency, charge, and maintains different 12V batteries as gel, AGM, SLA, VRLA, and lithium-ion battery. 【with 3 LED Indicate Light】The solar car battery charger features three indicator lights, Blue indicates sunlight reception by the solar panel, red indicates charging from solar panel to battery, and green indicates a fully charged battery. The MPPT requires 2 seconds for calculation and LED status switching. 【Robust and Durable Materials】Excellent performance of PC+ABS+Tempered glass material, Make allows the solar panels to easily cope with temperatures ranging from -40 to 137 degrees Celsius, and IP65 waterproof can survive heavy rain and high wind. Q&A Q1: Why does an MPPT controller improve the efficiency of solar panels? A1: 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 —— Q2: What types of batteries can the POWOXI solar battery charger maintain? A2: The POWOXI solar battery charger is suitable for maintaining any rechargeable 12V batteries, including Lithium-ion, LiFePO4, Gel, AGM, etc. —— Q3: Do I need to disconnect the solar panel while driving? A3: No, you don’t need to disconnect. Our solar panel is equipped with overcharge protection circuitry built into the panel, which prevents backward charging. —— Q4: Can the solar panel charge a car battery through a cigarette lighter when the car is off? A4: 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. —— Q5: Can I charge a battery that is almost dead with the POWOXI solar battery charger? A5: 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.
