Feature:1. The solar charge controller is often used in solar power generation systems, with short circuit, open circuit, reverse, and overload protection.2. 3‑stage PWM charging management is beneficial to improve system efficiency and extend battery life.3. With dual USB output, rated voltage of 12 and 24V, maximum current up to 2.5A, has strong practicability.4. Equipped with a display screen, which can clearly display status and data, and manually switch modes and parameter settings.5. Easy to install and operate, first connect the battery, then connect the solar panel, and finally connect the load.How to Use:1. Connect the positive and negative poles of the battery to the controller as shown in the figure, and the controller will automatically detect the battery voltage.2. Connect the positive and negative poles of the load to the controller as shown in the figure, be careful not to reverse.3. Connect the solar panel to the controller as shown in the figure.Specification:Item Type: Solar Panel ControllerMaterial: ABSModel: WBL1210Uses: Suitable for home, industry, commerce, etc.Rated Voltage: 12/24VMaximum Photovoltaic Voltage: 50VMaximum Photovoltaic Output Power: 260W (12V), 520W (24V)USB Output: 2 USB outputs, 5V/2.5A (maximum)Standby Current: <10mAWorking Temperature: -35-60℃ Package List:1 x Solar Panel Controller1 x User Manual
