Feature:1. 8 String Configuration: The PV combiner box has an 8 string configuration with a maximum current of 10A for a single PV input array and a rated continuous load of 250vdc per string. (Regardless of the solar panel specification, regardless of the connection method, whether in series or parallel, as long as the current and voltage of a single PV does not exceed 10A 250Vdc, the combiner box can be connected)2. Overload Protection: The single PV input array of this PV combiner box is fitted with a high voltage fuse with overload and overcharge protection.3. Short Circuit Proof: The PV combiner box has a professional high voltage circuit breaker control output with short circuit proof protection, making the system more reliable and safe.4. Anti Backflow Protection: The PV combiner box has an anti backflow diode, anti backflow and anti reverse protection, a touch safe circuit breaker and a non conductive box.5. Lightning Protection Module: This PV combiner box includes output cable connectors, safety labels and lightning protection module.Specification:Item Type: PV Combiner BoxMaterial: PCSpecifications:( Maximum Number ) Connected PV Arrays: 8(Maximum) Individual PV Array Input Current: 10ATotal PV Array Input Current: 80ATotal Maximum Input Voltage to PV Array: 1000VProtection Level: IP65Operating Ambient Temperature: -30C to +70CRelative Humidity: 0-95%Cooling Method: Natural coolingSurge Lightning Protection: Yes.Package List:1 xPV Combiner Box1 x Combination Lock4 x Fixed Tab14 x Screws4 x Spacer4 x Expansion Screw1 x Wrench2 x Instruction Manual
