## Summary description

HiSmart NV822317 is a PV combiner box for DC photovoltaic systems with 4 inputs and 4 outputs and IP66 protection. It consolidates multiple PV strings, provides a single point for DC distribution and protection, and is suitable for rooftop and ground-mounted arrays. Designed for outdoor use, it simplifies wiring, enables safer maintenance, and protects internal components from dust and water ingress.

## Long description

HiSmart NV822317 is a PV combiner box for DC photovoltaic systems with four inputs and four outputs, rated up to 1000 V DC and built to IP66 protection. The enclosure is flame-retardant (V0), UV-resistant and lockable, with MC4 connectors for straightforward string connections. The unit integrates DC switches and surge protection to consolidate multiple PV strings into a single, protected DC distribution point suitable for rooftop or ground-mounted arrays.
Advantages
The combiner box provides a compact, weatherproof solution for combining four PV strings into four outputs while offering over-voltage protection with four dedicated SPD modules and two lockable DC switches with patented arc-extinguishing chambers. Its polycarbonate enclosure meets IP66 dust/water resistance and V0 UL94 flame-retardant standards, simplifying external installation and maintenance. Cable gland sizes are provided for common PV cable diameters and the design meets relevant IEC and UL standards for DC switching and surge protection.
Suitable for
Small to medium rooftop PV systems with up to four strings
Ground-mounted arrays where a compact outdoor DC distribution point is needed
Installations requiring IP66 protection and flame-retardant enclosure
Systems that use MC4 connectorized PV modules

How to use
Mount the HiSmart NV822317 combiner box on a suitable outdoor surface in accordance with local electrical codes and the manufacturer’s mounting requirements. Connect up to four PV strings to the MC4 input connectors and route combined outputs through the output glands. Use the lockable DC switches to isolate the DC side before maintenance. Verify SPD installation and proper grounding before energising the system. Ensure cable diameters match the specified PG glands and tighten connections to the recommended torque values.
Usage recommendations
Install and commission the combiner box only by qualified personnel. Regularly inspect cable entries, gland seals and SPD indicators, and replace SPD modules after rated discharge events or as recommended by the manufacturer to maintain protection levels.
