Feature: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 safely2. 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 power4. TRANSPARENT AND RUST PROOF: Waterproof box is easy to install, transparent cover can check the status of the main switch and arrester, using IP67 flame retardant material, durable. Waterproof and rust resistant, internal wiring, safe, simple, easy to use and install, locking can protect your equipment5. 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 time6. 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 batteriesSpecification:Item Type: Solar PV Combiner BoxMaterial: Polycarbonate and ABSEnter: 2 StringsOutput: 1 StringMaximum Short Circuit Current(isc) Per Input: 15A(replaceable)Maximum Current Input: 32AProtection Level: IP67Impact Resistance: IK10Product Size(excluding protruding parts): Approx. 210 x 210 x 120mm or 8.27 x 8.27 x 4.72inCable Input: PG09 2.5-6mm, MC4-2.5-6mmOutput Current Sealing Ring: PG21 2.5-6mm, MC4-2.5-6mmDC Isolation Switch: DZ47 63ZRated Current(Le): 63ADC Arrester: NL PV40Maximum Discharge Current: 40KADC Fuse Holder: ZYPV 32XFuse: Approx. 10 x 38mm or 0.39 x 1.5in 15A.Package List:1 x Solar PV Combiner Box Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
