## Summary description

HiSmart NV820122 is a PV combiner box designed for DC photovoltaic installations with a 1 in – 1 out configuration and IP66 protection. It provides a compact connection and protection point for solar string wiring, suitable for outdoor and indoor use where ingress protection and reliable DC feed-through are required. Ideal for small-scale PV arrays and inverter connections.

## Long description

HiSmart NV820122 is a PV combiner box with a 1 input – 1 output configuration and IP66 protection, designed for DC photovoltaic installations. The compact polycarbonate enclosure provides a protected connection and feed-through point for a single PV string, integrating a DC switch, surge protective device (SPD) and cable glands for straightforward wiring in small-scale solar arrays and inverter connections.
Advantages
The unit integrates a 2-pole 1000 V DC, 25 A switch with a lockable door clutch and a patented DC arc extinguishing chamber with magnetic steels for rapid quenching. It includes a 3-pole 1000 V DC SPD rated at 40 kA (higher capacity 20 kA per IEC/UL) with response time \<25 ns. The polycarbonate enclosure is flame-retardant (V0), UV-resistant, and rated IP66 and IK10 for protection against dust, water ingress and impacts. The set comes with MC4 connectors and appropriate cable glands for easy installation.
Suitable for
Small residential or commercial PV systems with a single DC string
Outdoor or indoor installations requiring IP66 protection
Connection between a PV string and inverter or DC distribution

How to use
Mount the combiner box on a suitable flat surface following local electrical codes. Connect the PV string positive and negative conductors to the input terminals using the supplied MC4 connectors and glands sized 2.5–16 mm. Route the output conductors through the PG21 gland to the inverter or downstream DC distribution. Use the DC switch to isolate the PV string before maintenance; the lockable handle allows securing the switch in the off position. Ensure the SPD wiring and grounding are installed according to applicable standards.
Usage recommendations
Verify that the PV string Isc falls within the specified 15–30 A range and that the maximum system voltage does not exceed 1000 V. Install the combiner box in a location with adequate ventilation and access for maintenance, and follow local regulations for surge protection grounding and DC switching. Regularly inspect glands, connectors and the enclosure for damage or water ingress.
