Product information

Description

PV combiner box HiSmart NV822294 is a DC 2-in/2-out junction box with IP67 protection designed for solar string systems. It consolidates two input strings into two outputs, provides surge protection and isolation on the DC side, and is suitable for outdoor installation thanks to a UV-resistant, flame-retardant polycarbonate enclosure with lockable cover. The unit includes MC4 connectors and meets standards including IEC529/EN60529, CE and RoHS.

Advantages

Suitable for

  • Residential rooftop PV arrays with two string inputs

How to use

Mount the HiSmart NV822294 combiner box on a suitable surface in an outdoor location protected from direct mechanical damage. Connect the two PV string inputs using the supplied or compatible MC4 connectors and route the two outputs through the output glands. Verify the input short-circuit current range (15–30 A) and ensure the system voltage does not exceed 1000 V DC. Use the lockable DC switch to isolate the DC side during maintenance and rely on the built-in SPDs for surge protection.

Usage recommendations

Install and commission the PV combiner box in accordance with local electrical codes and the PV system designer’s instructions. Confirm compatibility of MC4 connectors and cable cross-sections with the specified gland ranges, and lock the switch handle when the system is in service. Replace SPDs following manufacturer guidance after significant surge events; observe the 24-month warranty and arrange periodic inspections within the specified operating temperature range.
