UNIRAC NULGMLP1 – NXT HORIZON MLPE & LUG CLAMP

UNIRAC NULGMLP1 NXT Horizon MLPE & Ground Lug Clamp – Dual-Function MLPE Mount & Grounding Solution

The UNIRAC NULGMLP1 NXT Horizon MLPE & Lug Clamp is a innovative dual-purpose component designed for the NXT Horizon and NXT UMOUNT rail-based solar racking systems. This all-in-one clamp securely mounts Module Level Power Electronics (MLPE) — such as microinverters and power optimizers — while simultaneously functioning as a grounding lug, eliminating the need for separate parts and streamlining installation.

Engineered for speed and efficiency, the NULGMLP1 integrates MLPE attachment and grounding into a single step, significantly reducing labor time, component count, and overall project costs while maintaining full UL 2703 and UL 3741 compliance.

Key Features & Benefits

• True Dual Functionality — One clamp handles both MLPE mounting and equipment grounding, reducing parts and simplifying BOMs.
• Fast Rail-Mounted Installation — Twist-in design slides easily into the NXT rail channel with zero interference from rail splices. Features a full-size ½” bolt head for consistent tooling across the system.
• Pre-Assembled Design — Comes complete with stainless-steel bolt, stainless-steel grounding plate, and plastic retention clip for faster, error-free installation.
• Domestic Content Compliant — Supports projects requiring U.S.-manufactured components.
• Universal Compatibility — Works with a wide range of microinverters, optimizers, and NXT UMOUNT Standard & HD rails.
• Robust & Reliable — High-quality materials ensure long-term durability and reliable bonding in all environments. Backed by Unirac’s industry-leading 25-year warranty.
