More features

• 2 IN 1 OUT SOLAR COMBINER BOX--This solar combiner box is designed to optimize the connection between photovoltaic (PV) arrays and inverters. It supports 2 set of PV panel input and 1 set of power output, with a maximum input current of 20A per string and a maximum output current of 40A for the circuit breaker. It supports up to 20kW of power in a 500V system. And provide overvoltage, overload, and quick disconnect functions to ensure the safety of the photovoltaic system;
• TRIPLE PROTECTION (MCB + SPD + FUSE)--This PV combiner box is equipped with 40A DC500V miniature circuit breaker (MCB), DC500V 40KA Class T2 surge protective device (SPD), and 20A DC500V fuse, forming a triple safety barrier. It enables protection against short circuits, overvoltage, overcurrent, leakage, and lightning. Meanwhile, it supports quick disconnection for easy maintenance, protecting core equipment such as PV panels and inverters from damage at the source.
• DURABLE IP65 WATERPROOF ENCLOSURE--The solar junction box is made of high quality ABS+PC material and features an IP65 waterproof rating. It exhibits excellent waterproof, flame-retardant, UV-resistant, and anti-aging properties. The combiner box is designed with a PC transparent cover, allowing visual inspection of the switch operation status. It can operate stably in harsh environments such as indoor, outdoor, rooftop, and open-air settings, extending the service life of the equipment.
• WALL MOUNTED COMBINER BOX--The solar combiner box comes with pre wired internal connections. Only the PV connectors, output power cables, and ground wires need to be connected. The package includes matching PV connectors, PV specific tools, ground wires, and mounting screws. Even without professional electricians, quick installation can be completed easily and conveniently.
• APPLICATION SCENARIOS--The PV combiner box is specifically designed for grid-connected or off-grid solar systems. It is widely used in various scenarios such as solar panel arrays, RVs, yachts, household rooftops, and small-scale PV power plants. With multiple safety guarantees, it ensures the long-term safe and reliable operation of the entire PV system, making it a preferred supporting equipment for various solar power generation projects.
