## Summary description

HiSmart NV820153 is a PV combiner box for DC photovoltaic systems with 4 inputs and 4 outputs, rated to IP66 protection. It consolidates multiple PV strings for safer distribution and simplifies wiring to inverters or charge controllers. The enclosure provides weather and dust resistance for outdoor use and aids in overcurrent protection and circuit organization during installation and maintenance.

## Long description

HiSmart NV820153 is a PV combiner box designed for DC photovoltaic systems with 4 inputs and 4 outputs, providing consolidated string connection, surge protection and isolation on the solar DC side. The IP66, IK10 and V0-rated polycarbonate enclosure is UV-resistant and suitable for outdoor installations. The set includes MC4 connectors and cable glands for straightforward wiring to inverters or charge controllers.
Advantages
The combiner box supports up to 1000 V DC and accommodates changeable short-circuit current per input from 15 A to 30 A. It integrates two 4-pole DC switches (1000 V, 50 A) with a patented DC arc extinguishing chamber and magnetic steels for rapid, safe interruption. Four 3-pole DC surge protective devices (1000 V, 40 kA) with a response time \<25 ns are built in for PV-specific lightning and surge protection. The enclosure’s flame-retardant, UV-resistant material and IP66/IK10 ratings ensure robust protection in external environments.
Suitable for
 Small to medium rooftop and ground-mounted PV arrays with four strings
 Systems requiring centralized DC string consolidation before the inverter
 Outdoor installations needing weatherproof and impact-resistant enclosures
 Installations where integrated surge protection and DC isolation are required
