Feature:1. The solar controller has multiple protection functions such as short circuit, open circuit, reverse and overload, and has good safety.2. Adopting 3‑stage PWM charging management can improve system efficiency and extend battery life.3. In order to protect the battery, once the battery voltage drops below 8V, the solar controller will automatically shut down.4. Equipped with LCD display screen can clearly display status and data, easy to switch modes and parameter settings.5. 12/24V dual USB charging mode, has low interference, suitable for home, industrial and other circuit protection.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: Smart Charge ControllerMaterial: ABSModel: CBK2410Uses: 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/1A (maximum)Standby Current: <10mAWorking Temperature: -35-60℃Package List:1 x Smart Charge Controller1 x User ManualNote:The charge controller is only suitable for open type/AGM/gel type acid batteries, not suitable for nickel metal hydride, lithium, lithium ion or other batteries.
