Features 1HIGH ACCURACY: Using advanced bimodal or multimodal tracking technology the controller can still accurately track the maximum power point when multiple peaks appear on the IV curve. 2HIGH EFFICIENCY: The built in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems with high conversion efficiency. 3SAFE CHARGING: With current limiting charging mode the controller will automatically reduce the charging power under over power and overcurrent to make the current reach the rated level. 4CLEAR DISPLAY: Equipped with LCD screen and LED fault indicator you can view equipment operating data and status and modify controller parameters to quickly identify system faults. 5TEMP PROTECTION: Adopts built in over temperature protection mechanism and has temperature compensation function which can prevent the controller from being damaged due to overheating. 6OTHER FUNCTIONS: Supports instantaneous high current startup of capacitive loads supports automatic identification of battery voltage and supports TVS arrester protection function. Specification Item Type: Solar Charge ControllerMaterial: Aluminum AlloyCharging Current: 20ADischarge Current: 20AMaximum PV Power: 260W 12V 520W 24V Package List 1 x Solar Controller1 x Cable2 x User Manual Note 1. The applicable voltage of the controller exceeds the safety voltage of the human body so please read the instructions carefully before use and operate the controller after completing the safety operation training.2. There are no parts that need to be maintained or repaired inside the controller and users are not allowed to disassemble and repair the controller at will.3. Install the controller indoors to prevent exposure of components and prevent water from entering the controller.4. Please install the controller in a well‑ventilated place to prevent the radiator from overheating.5. It is recommended to install an appropriate fuse or circuit breaker outside the controller.6. Before installing and adjusting the wiring of the controller be sure to disconnect the wiring of the PV array and the fuse or circuit breaker near the battery terminals.7. Check that all wiring is tight after installation to avoid the risk of heat build‑up due to poor connections. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
