Welcome to the store! 1. PWM Charging: 12V 24V system voltage is automatically recognized, and the upgraded 3-stage PWM charging algorithm is used to perform periodic or over-discharge balanced charging of the battery, effectively preventing battery imbalance and vulcanization, and extending battery life. 2. Temperature Compensation and Comprehensive Protection: With temperature compensation, charging parameters can be adjusted automatically. A variety of load working modes are suitable for different types of loads. Provide overcharge, over-discharge, overload protection, short-circuit protection. 3. Multifunction: The advanced load start method is adopted, and the large capacity load can also be started smoothly. The product provides a grid graphic LCD display and a one-button human-machine interface. User-friendly browser and dynamic interface design ensure convenient, fast, and intuitive operation. With an industrial design, the product can operate normally under a variety of harsh conditions. With TVS light protection. 4. LCD Display: The solar charge controller is equipped with an LCD display, which can clearly show the status and data, and easily switch modes and parameter configuration. The large backlit LCD screen can adjust charging and discharging parameters and has a power-off memory function. 5. High Efficiency: Our controller can connect two solar panels, which is more efficient than other controllers.
