Features 1、PROFESSIONAL PHOTOVOLTAIC JUNCTION BOX: Suitable for your photovoltaic grid connected or off grid solar power generation system. Make your solar panel system work reliably and safely 2、MULTI FUNCTION: Photovoltaic array input, 1st level combination, fast cut off circuit, lightning protection, prevent reverse connection, overload protection, etc. 3、MAIN PURPOSE: Built in 4 separate 15A rated fuses(10x38mm). The maximum current of a single photovoltaic input array is 15A and the function is overload protection. Protects the photovoltaic solar panels and inverters. In addition, the length of the cable connecting from the panel to the inverter will be reduced, optimizing the system instructions to make the system more useful and maintainable. Will enable the photovoltaic power generation system to increase the output power 4、TRANSPARENT AND RUST PROOF: Waterproof box is easy to install, transparent cover can check the status of the main switch and arrester, using IP65 flame retardant material, sturdy. Waterproof and rust resistant, internal wiring, safe, simple, easy to use and install, locking can protect your equipment 5、LIGHTNING PROTECTION: 63A air circuit breaker can provide short circuit failure protection and control of the junction box output. This is a surge protection device. The arrester provides lightning protection. Green indicates normal, if it turns red, it indicates that lightning strikes occur and you need to replace the lightning protection module in time 6、APPLICATION SCENARIO: The junction box is the perfect device for outdoor installation and use, suitable for photovoltaic grid connected and off grid power generation and energy storage systems, compatible with any brand of solar panels and batteries Specification Item Type: Solar PV Combiner Box Material: Polycarbonate and ABS Enter: 2 Strings Output: 1 String Maximum Short Circuit Current(isc) Per Input: 15A(replaceable) Maximum Current Input: 32A Protection Level: IP65 Impact Resistance: IK10 Product Size(excluding protruding parts): Approx. 210 x 210 x 120mm / 8.27 x 8.27 x 4.72in Cable Input: PG09 2.5-6mm², 2.5-6mm² Output Current Sealing Ring: PG21 2.5-6mm², 2.5-6mm² DC Isolation Switch: DZ47 63Z Rated Current(Le): 63A DC Arrester: NL PV40 Maximum Discharge Current: 40KA DC Fuse Holder: ZYPV 32X Fuse: Approx. 10 x 38mm / 0.39 x 1.5in 15A Package List 1 x Solar PV Combiner Box
