Upgraded MPPT Charging Technology: The 100A MPPT solar panel charging controller is equipped with an industrial-grade main control chip and adopts advanced Mppt maximum power point tracking technology algorithm. During system operation, it quickly tracks the maximum power point of the photovoltaic array, with a tracking efficiency of no less than 99.5%. The charging efficiency is 15% to 30% higher than that of ordinary controllers, significantly improving the energy utilization rate of the solar system.
Compatible with Multiple Battery Types: This 100A MPPT solar panel charging controller is suitable for SLD, Lithium, Seal, GEL, Flooded and LifePO4 batteries. (Note: Lithium batteries must come with protection boards from official manufacturers and have the full charge parameters set before they can be charged.) It also provides a complete four-stage charging management (Bulk, float, boost and equalization charge), which helps improve system efficiency and extend battery life.
Backlit Liquid Crystal Display Screen: The display screen of the solar panel controller is backlit, allowing you to clearly understand the real-time data of the system operation, including the status of the battery and solar panel, mode control, load output status, battery voltage, photovoltaic charging current, battery discharge current, product working temperature, delay time, etc. Pressing the set key, up key and down key enables you to set the mode and adjust the parameters. This enables you to easily monitor and optimize your solar power generation system.
7 Operating Modes: This 100A charging controller offers seven different operation modes, meeting various scenarios for you. The seven operation modes are: charging mode, light control mode, light control + delay control mode, general control mode, manual control mode, timing control mode and test mode. (Among them, the test mode is only applicable for factory testing purposes.) You can set the corresponding mode according to your needs.
Multiple Security Protections: The safety of the charging system operation is of the utmost importance. Therefore, our controller provides multiple safety protections, including short-circuit protection, open-circuit protection, overcurrent protection, overload protection, over-discharge protection, overvoltage protection, overheat protection, reverse connection protection, power failure protection, overcharge protection, etc., to ensure that your system can operate smoothly under any conditions and provide peace of mind for your solar investment.
System Connection: When using the device, please first connect the charging battery and ensure that the battery has power.(the controller will detect the battery voltage and automatically identify 12V/24V/36V/48V). After the device is powered on successfully, connect the solar panel, and finally connect the light bulb. This way, it can work smoothly. Additionally, the two USB ports can be connected to devices such as mobile phones, and the rightmost port can be connected to the light strip.
2 5V/1.5A USB Charging Ports: On the left side of the 100A MPPT charging controller, there are two 5V/1.5A USB output ports, which can charge your tablets, laptops, mobile phones, headphones and other devices.
Warm Reminder: This solar controller integrates maximum power point tracking (MPPT) and pulse width modulation (PWM) charging technologies, featuring extremely high charging efficiency and excellent cost-effectiveness. Although it may not achieve 100% true maximum power point tracking functionality, it still provides reliable performance.
Reliable Warranty: Our 100A MPPT solar battery charging controller offers a 12-month warranty and lifetime technical support. If you have any questions, please feel free to contact our technical support team. Our engineers can help you identify the problem, provide suggestions and solutions.
