Overview

The nVent RF-2-6 Solar Combiner Box is a UL/CUL-listed, 1500VDC-rated fiberglass combiner designed to aggregate power from up to six solar PV strings in ungrounded systems. This NEMA 4X, IP68-rated enclosure combines touch-safe fuse holders, oversized busbars, and integrated surge protection to minimize voltage drop and safeguard inverters from over-current/over-voltage events. Built to IEC 60947-3 and UL 98B standards, the RF-2-6 features silver-plated copper terminals, a UL 94 V-0 flame-resistant housing, and a 250A operational current rating. Its fiberglass construction resists UV, chemicals, and extreme weather, making it ideal for residential, commercial, and utility-scale PV systems. Pre-assembled in the USA with premium components, this combiner box simplifies installation with preconfigured layouts and reduces labor costs through streamlined wiring. Compatible with any solar panel brand, it ensures long-term reliability in harsh environments while meeting NEC Article 690 requirements.
