Overview

The nVent RF-8 Solar Combiner Box is a grounded DC combiner designed for photovoltaic (PV) systems, supporting up to 8 solar panel strings into a single output. Housed in a fiberglass-reinforced polyester (FRP) enclosure measuring 17.32" x 15.32" x 6.65", the RF-8 delivers protection against UV exposure, chemicals, and moisture ingress with IP68 and NEMA 4X ratings. The enclosure features a full-length piano-hinged door with a non-metallic latch for easy access and maintenance. Brass inserts on the rear wall and lid provide versatile mounting options for seamless integration into any solar installation. Built to IEC and UL standards, the RF-8 incorporates oversized busbars to reduce electrical losses and improve system efficiency. The grounded configuration enhances safety by providing a dedicated ground path for all inputs, reducing the risk of electrical faults. The combiner box includes a touch-safe fuse holder and circuit breakers mounted internally for added protection against over-current and over-voltage conditions. Additionally, the RF-8 is equipped with a DC disconnect switch for safe isolation of the PV array during maintenance or emergencies.
