Product information

Description

HiSmart NV821365 is a PV combiner box for solar arrays with 8 DC inputs and 8 DC outputs, designed to consolidate multiple PV strings into a single feed. The IP66-rated polycarbonate enclosure provides protection against dust and powerful water jets and is rated IK10 for impact resistance and V0 for flame retardancy. The unit includes MC4 connectors and cable glands and is intended for outdoor solar DC installations up to 1000 V DC.

Advantages

The combiner box integrates surge protection devices (SPD) and DC switches in a compact, lockable enclosure to simplify wiring and improve safety on the DC side of solar systems. Patented DC arc extinguishing chambers and internal magnetic steels ensure rapid arc interruption in the DC switches. SPDs are specified for fast response and high discharge capacity, while the IP66/IK10/V0-rated polycarbonate housing ensures durable performance in harsh outdoor conditions.

Suitable for

  • Residential and commercial solar arrays with up to 8 PV strings

How to use

Mount the combiner box on a suitable flat surface in an accessible outdoor location. Connect up to eight PV string positive and negative leads to the designated input terminals using the supplied MC4 connectors and appropriate cable glands. Route the consolidated outputs to the inverter or downstream DC equipment. Ensure the DC switches are in the OFF position before making connections and lock the handle after installation. Follow local electrical codes and the inverter manufacturer’s instructions when integrating the combiner box into the PV system.

Usage recommendations

Regularly inspect cable gland seals, MC4 connectors and the enclosure for damage or ingress. Verify SPD condition after major surge events and test switches periodically to ensure proper operation. Use this combiner box within specified voltage and current limits and in accordance with local regulations and safety standards.
