Product information

Description

HiSmart PV Combiner Box NV820146 is a DC string combiner with 3 inputs and 3 outputs, designed for outdoor solar installations. The IP66 polycarbonate enclosure provides protection against dust and powerful water jets, with IK10 impact resistance and V0 flame-retardant rating. The unit centralises string connections, integrates surge protection and a lockable DC switch to simplify wiring and improve safety for rooftop or ground-mounted PV systems.

Advantages

The combiner box includes three DC surge protection devices (3P, 1000V, 40kA) and a patented 6-pole DC switch (1000V, 50A) with an arc-extinguishing chamber and magnetic steels for fast, reliable interruption. The enclosure is UV resistant and rated IP66 for weather protection. Set components include MC4 connectors and cable glands, enabling straightforward installation and sealed cable entry. Operating temperature range and changeable short-circuit current settings make the unit suitable for many small commercial or residential string configurations.

Suitable for

  • Combining three PV strings into a centralized DC output for inverters

Verify surge protection modules are correctly installed and that all cable entries are sealed to maintain IP66 protection.

Usage recommendations

Confirm PV string Isc settings and cable sizes comply with system design. Perform periodic visual inspections of the enclosure, glands and connectors, and test the DC switch and SPD devices per maintenance schedules.
