Overview

The nVent CUF04-1000V Solar Combiner Box (SKU: CUF04-1000V) is a fiberglass enclosure designed for commercial photovoltaic (PV) systems. This 4-pair combiner box consolidates power from multiple solar panels onto a common bus, optimizing performance for charge controllers or inverters. Its light gray fiberglass enclosure resists UV radiation, chemicals, and extreme weather, meeting NEMA 4X, Type 6P, and IP68 ratings for water and dust ingress protection. The box accommodates wire sizes from #24 to #3 AWG for input and output, ensuring compatibility with a wide range of system designs. With a 1000V rating, it supports modern high-voltage solar installations while minimizing voltage drop between the array and balance-of-system components. Prearranged configurations streamline installation, reducing labor costs and complexity. Assembled in the USA using premium components, the CUF04-1000V delivers reliable performance in harsh outdoor environments.
