CUF18-1000V

Overview

The CUF18-1000V is a solar combiner box manufactured by nVent Hoffman, designed for photovoltaic applications. Constructed from fiberglass, it features a smooth matte finish and provides NEMA Type 3 protection against environmental elements. The unit measures 21.32 x 17.32 x 11.57 inches, offering a compact footprint suitable for various mounting configurations. This enclosure supports up to 18 input circuits, facilitating efficient current combination in solar energy systems while ensuring safety and durability.

Feature Summary

• Constructed from durable fiberglass material for robust environmental resistance
• Provides NEMA Type 3 protection rating for outdoor suitability
• Supports up to 18 input circuits for solar array management
• Features a smooth matte finish for aesthetic integration

Applications

• Photovoltaic (PV) solar power generation systems
• Solar combiner stations requiring multiple circuit inputs
• Outdoor renewable energy infrastructure installations
• Utility-scale or commercial solar farm deployments

Procurement Notes

Verify that the specific project requirements align with the fiberglass construction and NEMA Type 3 rating. Confirm that the 18-circuit capacity meets the design specifications for the intended solar array configuration. Ensure compatibility with existing mounting structures given the physical dimensions of 21.32 x 17.32 x 11.57 inches. Review relevant electrical codes and standards applicable to solar combiner boxes in the deployment region.

Selection Notes

Select this model when a non-metallic enclosure is required for corrosion resistance or weight reduction in solar applications. The fiberglass composition distinguishes it from steel alternatives, making it suitable for harsh chemical or coastal environments. Consider the 18-input capacity relative to panel string counts to avoid underutilization or overcrowding. Evaluate the NEMA Type 3 rating against local weather conditions to ensure adequate protection.

Part Context

This component belongs to the CUF series of solar combiner boxes from nVent Hoffman. It is part of a range designed specifically for photovoltaic energy systems, emphasizing ease of installation and reliable performance. The series utilizes tool-free assembly features common to Hoffman enclosures, streamlining the setup process for field technicians and reducing overall installation time.

Replacement Considerations

Consult official nVent Hoffman documentation for direct cross-references. Verify dimensional compatibility if substituting with other models in the CUF series. Ensure replacement units maintain the same fiberglass material specification and NEMA Type 3 rating to preserve environmental protection levels.
