Product information

Description

The CNC PV Combiner Box NV822331 is a DC string combiner designed for photovoltaic systems with 8 inputs and 8 outputs. Housed in an IP66 polycarbonate enclosure with V0 flame-retardant rating and UV resistance, the unit integrates DC switching, surge protection and MC4 connectors to consolidate string connections and simplify DC distribution for residential and commercial solar installations. Dimensions: 528 x 458 x 358 mm. Standards include IEC60529 for enclosure protection.

Advantages

The combiner box combines eight PV strings into eight outputs while providing built-in DC switches with lockable handles and a patented DC arc extinguishing chamber for safer isolation. Integrated DC surge protection devices (SPDs) respond in less than 25 ns to protect downstream equipment. The enclosure is IP66 rated for dust and water ingress, UV resistant and meets V0 UL94 flame-retardant requirements.

Suitable for

Small to medium rooftop PV systems with multiple string inputs
Ground-mounted commercial arrays requiring grouped string protection
Outdoor installations needing IP66 weatherproof enclosures
Installations using MC4 connector cabling

How to use

Mount the combiner box on a suitable flat surface following local electrical codes and the manufacturer’s installation instructions. Connect up to eight PV string outputs to the MC4 input connectors and route the combined outputs through the output glands. Use the lockable DC switches to isolate strings during installation and maintenance. Ensure SPDs and switches are accessible for inspection and that cable sizes match the specified gland ranges and current ratings.

Usage recommendations

Install the PV Combiner Box NV822331 in a shaded or ventilated location when possible, keep connectors and glands sealed to maintain IP66 protection, and verify that system voltage and string Isc do not exceed the specified ratings. Schedule periodic inspections of connections, SPDs and the enclosure to ensure continued protection and reliable operation.
