Features 1Battery Charging: This MPPT solar controller maximally converts solar panel energy to battery charging. 2Synchronous Rectification: This solar charge controller adopts highly efficient synchronous rectification circuit structure. 3Anti 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. 4Multiple Protection: This MPPT solar controller supports short circuit protection overtemperature protection solar input undervoltage protection battery undervoltage protection load port short circuit protection. 5Wide 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. Specification Item Type: MPPT Solar ControllerMaterial: PlasticNormally Open: 24 Hours Load OutputEfficiency: 95%Noise: < 55dBApplication: Solar Street Lamp Controller Solar Charger Solar Electric Bike Solar Electric Tricycle Solar Toy Car Household Solar Panels Solar Monitoring and Other Application ScenariosSuitable for Photovoltaic Panel Specification: Open Circuit Voltage: 21 to 25BCharger Module:PV Input Power: 150WPV Input Starting Voltage: >17VPV Input Tracking Voltage: 16 to 25VOutput to Battery Current: 10A (Maximum 12A)No Load Loss: 20MAVoltage Adjusted Rate: 1%No Load Adjusted Rate: 5%Full Load Ripple: 400mVNo Load Ripple: 100mVDischarge Module:Input Voltage: Equal to Battery VoltageLoad Output Voltage: Equal to Battery VoltageLoad Output Current: 10AStatic Power Consumption: 12mALoad Output Mode: Normally OpenProtection Module:Battery Short Circuit Protection: YesLoad Short Circuit Protection: YesTemperature Protection: YesAnti Backflow Protection: YesProtection Level: IP67Operating Temperature: Minus 40 to +65Overheating 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. Package List 1 xMPPT Solar Controller Note The MPPT controller should be fixed on an iron or metal bracket to avoid the vibration of the machine due to instability.The MPPT controller should allow some space around the enclosure.Output and input wires should be kept as short as possible to avoid excessive energy dissipation during transmission.There is high voltage and high current in the machine and non‑professionals are not allowed to disassemble.The input and output terminals should be reliable and not loose so as to avoid heating at the connection point.
