PV-combinerbox CNC NV822324 DC 6in-6out IP66

PV Combiner Box CNC NV822324 is a DC junction enclosure for photovoltaic systems with 6 inputs and 6 outputs, designed to centralize and protect string connections. Rated IP66 and made of flame-retardant polycarbonate (V0 UL94), the box simplifies wiring for rooftop and ground-mounted arrays and provides space for DC switching and surge protection devices at up to 1000 V DC.

Advantages

The combiner box supports six string inputs and six outputs with MC4 connectors, offering a compact solution for consolidating PV strings. It features lockable DC switches with a patented arc extinguishing chamber, integrated DC surge protection devices (SPD) with response time under 25 ns, and an IP66 waterproof, UV-resistant enclosure for outdoor use. The polycarbonate housing meets IEC60529 and provides V0 flame-retardant performance.

Key specifications

How to use

Mount the CNC NV822324 combiner box on a suitable surface following local electrical codes and the manufacturer’s mounting instructions. Connect up to six PV strings to the input MC4 connectors and route the combined outputs through the output glands. Ensure DC switches are in the correct position and that surge protection devices are installed and connected per system requirements. Verify all cable sizes and tightening torques comply with the specified current ratings and local regulations before energizing the system.

Recommendations

Use qualified personnel for installation and maintenance. Regularly inspect seals, cable glands, SPD condition and switch operation. Replace SPDs after they reach their nominal discharge capacity or show signs of damage. Do not exceed rated voltages and currents and follow applicable standards (IEC60529, IEC60947-3, IEC61643-31, EN50539-11).
