Solar Panel Cable 4mm² with MC4 Connectors | 1500V DC Outdoor PV Extension

Product Description

This 4mm² solar extension cable comes with MC4 connectors factory‑crimped on both ends. Rated at 1500V DC, it works with modern high‑voltage string inverters and bifacial panel arrays. The connector housing uses UV‑stabilized PPO material, matched with gold‑plated copper contacts to keep contact resistance below 0.5 mΩ.

The cable itself meets PV1‑F or H1Z2Z2‑K construction (tinned copper / XLPE insulation). IP68 rating allows direct burial, outdoor exposure, or conduit routing. Each length is tested for insulation resistance and connector pull‑out force before packing.

Key Features

4mm² tinned copper conductor – resists oxidation in humid or coastal environments.
1500V DC system rating – compatible with modern utility‑scale and commercial PV systems.
MC4 connectors (male & female) – type IV certified, locking latch with audible click.
IP68 waterproof – dust‑tight and submersible for outdoor or underground use.
Wide temperature range – -40°C to +90°C (cable); -40°C to +85°C (connector).
Pre‑assembled – no on‑site crimping, saves installation time and reduces failure points.

4mm2 Solar Panel Cable With MC4 Connectors 1500V DC Outdoor PV Extension

Why choose this pre‑assembled cable?

Three reasons: one less failure point (no field crimping), verified 1500V DC insulation, and connectors that lock tight without special tools. Installers report 30% faster string wiring compared to loose cable + separate connector kits.
