Metal PV Combiner Boxes (2/2, 3/3, 4/4, 6/6, 8/8)

The CNC solar combiner box provides a safe, highly efficient way to connect and combine photovoltaic panel strings (in = out). Designed specifically to protect medium and large solar systems, it contains all the advanced DC protection elements needed for stable, safe inverter performance, while keeping the wiring tidy and professional.

⚡ Features:

Efficient combining: groups sets of solar panels to simplify wiring and reduce the load and branching on the inverter.

Complete DC protection: fitted with DC breakers, dedicated solar fuses on each string to protect against reverse currents, and a DC surge protector (DC SPD) against sudden voltage spikes.

Weather-resistant body: a tightly sealed IP65 design gives full protection against dust and rain, ideal for outdoor installation in power plants.

Excellent insulation and safety: provides strong electrical insulation to keep technicians safe during routine maintenance or troubleshooting.

Reduced energy loss: uses high-quality copper connections and busbars inside the box to reduce electrical resistance and keep the energy from the panels flowing efficiently.
