1、Battery Charging: This MPPT solar controller maximally converts solar panel energy to battery charging. 2、Synchronous Rectification: This solar charge controller adopts highly efficient synchronous rectification circuit structure. 3、Anti Backflow: This solar energy controller possesses anti backflow function. When there is sunlight, the controller charges the battery normally. When there is no sunlight, the controller can effectively prevent the battery from flowing back. 4、Multiple Protection: This MPPT solar controller supports short circuit protection, overtemperature protection, solar input undervoltage protection, battery undervoltage protection, load port short circuit protection. 5、Wide Application: This MPPT solar controller is widely used in solar street lamp controller, solar charger, solar electric bike, solar electric tricycle, solar toy car, household solar panels, solar monitoring, etc. Item Type: MPPT Solar Controller Material: Plastic Normally Open: 24 Hours Load Output Efficiency: ≥95% Noise: < 55dB Application: Solar Street Lamp Controller, Solar Charger, Solar Electric Bike, Solar Electric Tricycle, Solar Toy Car, Household Solar Panels, Solar Monitoring and Other Application Scenarios Suitable for Photovoltaic Panel Specification: Open Circuit Voltage: 21 to 25B Charger Module: PV Input Power: 150W PV Input Starting Voltage: >17V PV Input Tracking Voltage: 16 to 25V Output to Battery Current: 10A (Maximum 12A) No Load Loss: 20MA Voltage Adjusted Rate: 1% No Load Adjusted Rate: 5% Full Load Ripple: 400mV No Load Ripple: 100mV Discharge Module: Input Voltage: Equal to Battery Voltage Load Output Voltage: Equal to Battery Voltage Load Output Current: 10A Static Power Consumption: 12mA Load Output Mode: Normally Open Protection Module: Battery Short Circuit Protection: Yes Load Short Circuit Protection: Yes Temperature Protection: Yes Anti Backflow Protection: Yes Protection Level: IP67 Operating Temperature: Minus 40℃ to +65℃ Overheating Protection: when the Internal Temperature of the Mppt Controller Exceeds 100℃ , the Mppt Controller Will Reduce the Output Power. if the Internal Temperature Continues to Rise to 110℃, the Mppt Controller Will Automatically Turn off the Output. when the Internal Temperature of the Mppt Controller is Lower Than 90℃, the Mppt Controller Will Automatically Resume Operation. 1 x MPPT Solar Controller
