Solar PV combiner box features an IP66 heavy-duty steel enclosure (Q235 cold-rolled steel, electrostatic coated for corrosion resistance), a 3-input 1-output compact design, and a 32A / 1000V DC rating. It integrates DC fuses per string, a surge protection device (SPD), and a DC circuit breaker for overcurrent, overvoltage, and fault isolation. Key conductive parts use T2 tin-plated copper busbars, internal wiring is XLPE-insulated high-temperature copper cable, and all plastic components are made of flame-retardant PA66/PC materials for electrical safety. The unit supports customizable component brands and smart monitoring modules, undergoes 100% hipot, insulation, and continuity tests before delivery, and comes with a 2-year whole-unit warranty – delivering safety, durability, and flexibility in one solution.
