Auto-sensing Solar Street Light

Auto-sensing solar street lightAuto-sensing solar street light made by solar cells, pv controller, storage battery, LED lamp and poles . The whole light with overcharge , over discharge ,and reverse connection protection, with control, optical control and other functions, can adjust and control automatically.Operation PrincipleAuto-sensing solar street light, using solar panels to absorb solar power and store solar power into the battery.When environment illumination is less than 30-50 Lux, the light will be on, also when there is people go by, the light will output full power, if no one pass,the whole system will run with 1/3 of the total powerFeatures·Integrated  PV,battery, and the head of lamp, all together,easy to install.· LED lights automatically lit,according to the light intensity .·Using high safety, long cycle life lithium battery.ModelL15-108L25-160PVTypeMonocrystalline SiliconMonocrystalline SiliconPower20W40WDimension344mm×480mm344mm×754mmLED LampPower15W25WSolar Charging and Discharging ControllerTypePWMPWMSystem Voltage12V12VRated Charging Current3A3AMaximum Photovoltaic Voltage22V22VMaximum Output Power10W20WOptically Controlled Opening ThresholdPV 8V(Delay10S)PV 8V(Delay10S)Optically Controlled Closing ThresholdPV 8V(Delay1min)PV 8V(Delay1min)IP degreeIP68IP68Lithium  BatteryTypeLithium Iron PhosphateLithium Iron PhosphateNominal Voltage12.8V12.8VNominal Capacity8.5Ah8.5AhCharging Temperature0℃~70℃0℃~70℃Discharging Temperature-20℃~80℃-20℃~80℃Cycle Life3000 residual>80%3000 residual>80%SafetyAcupuncture, overcharge, heavy impacting, short circuit, no fire, no explosion.Whole LampWorking ModeWhole system will run with 1/3 of the total power, when  people pass, it will full power running.Full Power Operation Duration10h8h1/3 Power Operation Duration30h24hDimension960×400×110mm1230×400×110mmWeight10.3kg13.8kg
