Solar system is the solution to solve customer's power problem by using sun power. According to different installed information and different power using, every system is different after design-off grid solar system ,on grid solar system ,hybrid solar system.There is no same system after design if you are professional and without enough, we can't design it.Note : Every system need to be designed, this system is only for referenceProduct ParametersItemSpecificationGuaranteeWorking LifeSolar PanelClass:AWeight:19.5KGSize:1640×992×40mmPower:250W, 36VType: POLY10 years25 yearsInverterCommunication:CH235 Protection degree:IP20THD＜3%Max.DC Voltage(V):40-57Input Voltage: 48VDC,Operating Temperature:-20℃ to +40℃Efficiency:90%Output Voltage:220±3%,50HZ/60HZ3 year25 yearsControllerCommunication:CT232Protection degree:IP20Efficiency:93%Voltage range(v):58-75VDC3 year25 yearsMounting SystemMaterial: Steel Q235B (HDG: Hot Dip Galvanized)  Module Orientation: Landscape or Portrait   Snow Load:1.6KN/M2  Wind Load:60m/s  Tilt Angle:5-60 °   Foundation: Concrete Base   Installation site: Flat Roof3 year25 yearsBatteryWork Capacity Temperature:'-20℃ ～+85℃Cycle use: 300 cycles at 100% DOD500 cycles at 50% DOD1000 cycles at 30% DOD1 year7 yearsCombine BoxWeight:40kgSize: 1200* 800*600MM (Reference)Q235:1.5MM1 year25 yearsSolar Panel 250WModel: Poly Maximum Power: 250WOptimum Power Voltage: 31.02VOptimum Operating Current: 8.06AOpen Circuit Voltage: 36.99VShort Circuit Current: 8.26ACell Efficiency: 17.13%Module Efficiency: 15.40%Solar InverterInverter:1000W (Reference)Communication:RS232Warranty:5Yearsize:440*286*43.5MMWeight:5KGSolar ControllerController:48V,30A (Reference)Voltage range(v):58-75VDCEfficiency:93%Protection degree:IP20Communication:RS232size:440*170*500MMWeight:9.8KGBatteryPower:12V,200AH (Reference)Cycle use:300cycles at 100% DOD500 cycles at 50% DOD1000 cycles at 30% DODWork Capacity Temperature:'-20℃ ～+85℃Size:410*177*365MMWeight:57.3KGMounting SystemInstallation site: Flat Roof  Foundation: Concrete Base   Tilt Angle:5-60 °   Wind Load:60m/s  Snow Load:1.6KN/M2  Module Orientation: Landscape or Portrait   Material: Steel Q235B (HDG: Hot Dip Galvanized) Mounting System need installed information to design
