100mm² MC4 Connectors: Heavy-Duty Pair for High-Capacity Solar Cabling

This pair of 100mm² male and female MC4 connectors is made for demanding solar installations where standard MC4 connectors fall short. Built to handle large conductor sizes and high current, they’re suitable for advanced battery banks, inverter strings and DC bus links in commercial-scale PV systems.

High Current Capability for Serious Solar Setups

Unlike standard 4–6mm² MC4s, these are engineered to terminate thick 100mm² solar DC cable safely and reliably, delivering secure connections that reduce energy loss and installation risk.

  • Supports heavy-gauge 100mm² PV cable
  • Rated for high-voltage, high-amperage solar applications
  • Durable construction and IP-rated weather resistance

Ideal for Commercial & Industrial Solar Systems

These connectors are perfect for combiner boxes, large battery inverters, or main PV cable runs where cable size and current demand exceed typical residential setups.

Why LAMPS Recommend This Product

  • Helps ensure secure connections in high-demand solar installations
  • Reduces risk of loose terminations on thicker DC cables
  • Backed by trusted design used across UK solar projects

Installation & Compatibility

These MC4 connectors are only compatible with 100mm² PV cable. For other sizes, see the standard MC4 pair (4–6mm²). For safe termination, we recommend using the MC4 Crimping Tool.
