Features: 1.Automatic Voltage Identification: 12V/24V system voltage is automatically identified, and the 3 stage PWM charging algorithm is used to perform periodic or over discharge equalization charging on the battery, effectively preventing battery imbalance and vulcanization, and extending battery life. 2.Temperature Compensation: The Solar controller adopts temperature compensation, the charging parameters can be automatically adjusted, and a variety of load working modes are used to facilitate the product to be suitable for different types of loads. The product provides overcharge, overdischarge, overload protection, and short circuit protection. 3.Load Start Up Method: The Solar controller adopts an advanced load start up method, and large capacity loads can also be started smoothly. The controller can connect two solar panels, which is more efficient than other controllers. 4.One Key HMI: Provide graphic LCD screen and one key human machine interface, user friendly browser and dynamic interface design to ensure convenience and speed. With TVS light protection. 5.LCD Display: The solar controller is equipped with an LCD display, which can clearly display the status and data, and can easily switch modes and parameter configuration. The large screen LCD display with backlight can adjust the charging and discharging parameters, and has a power off memory function.
