Weight: 5.02 lb Item Description 1.HIGH QUALITY: The combiner box for solar panels is made of high quality electrical configuration with multi-functionality: first-class combination of PV array inputs, fast circuit cut-off, lightning protection, reverse direction protection, overload and more. Professional PV combiner box for your PV on/off grid solar power system. This makes your solar panel system work reliably and safely 2.SAFETY AND DURABLE: Solar Combiner Box enclosure is made of V0 grade flame retardant material to avoid fire hazards. Our Solar Combiner Box is made of professional wires, the thickened conductive wires are optimized for longer service life, especially for solar energy systems. Built-in ground wire connector is convenient for you to install the ground wire. Please make sure the current and voltage of a single PV array does not exceed 16A/260VDC 3.WIDE RANGE OF APPLICATIONS: It can support PV grid-connected/off-grid solar power system, solar panel system, it can support up to 780W solar panel system in 12V system, 1560W in 24V system and 3120W in 48V system 4.CONFIGURATION: Built-in four 15A rated fuses with a maximum current of 15A for a single PV input array. they function as overload protection. 1 x 63A air circuit breaker it provides short circuit fault protection and controls the output of the Combiner Box. 1 x surge protector/surge arrester provides lightning protection 5.PERFORMANCE: the solar panel box protects the PV solar panels and the inverter. . In addition, it will reduce the length of cable connections from the panels to the inverter and optimize system commands making the system more useful and easier to maintain. All in all it will enable the PV power system to increase the output power Product Description Our PV Combiner Box is a device designed to reduce the connection line between PV modules and inverter, facilitate maintenance and improve reliability. Using PV Combiner Box, users can connect a certain number of PV modules with the same specifications in series to form a series of PV modules according to the DC voltage range of the inverter input, then connect several series to the PV Combiner Box. The PV combiner box is suitable for photovoltaic grid-connected and off-grid power generation systems. Its main function is to converge the input of PV array. It has three protection measures: 1: The PV combiner box is configured with photovoltaic dedicated high-voltage lightning arrester, DC fuse and circuit breaker to provide short circuit fault protection and lightning protection. 2: It has protect function of over-voltage and over-current so as to avoid damage to photovoltaic panels and inverters when the fault occurs. 3: The PV combiner box is also used to reduce the connection of the photovoltaic array to the inverter, optimize the system structure, improve the reliability and maintainability of the system, make the photovoltaic system at its best. All wires are pre-wired in the box. Our solar combiner box is used professional wires that are especially for solar system. Built-in with 16A Rated Current Fuse, Surge Protective Device and 63A Air Circuit Breaker and a ground wire connector, the ground wire installation is available. Return Policy ?
