Key Benefits of the Suntree MC4 Connector
Reliable DC Connection for Solar PV Systems
The SUNTREE MC4 connector pair is designed to create a stable, secure and weatherproof connection between PV cables. Once correctly crimped and locked, the connector helps maintain safe current flow across solar panel strings and inverter-side DC wiring.
Designed for 4–6mm² Solar Cables
This connector set is compatible with 4–6mm² PV cables, also known as AWG 10/12 solar cables, with an outer cable diameter of approximately 3–6mm. This makes it suitable for common European PV cable standards used in residential, commercial and industrial solar installations.
IP67 Waterproof and Dustproof Protection
With an IP67 ingress protection rating, the connector pair is suitable for outdoor solar PV environments where long-term resistance to moisture, dust and weather exposure is essential. This makes it a practical choice for rooftop PV arrays, ground-mounted systems and exposed DC cable routes.
Silver-Plated Copper Contacts
The connector contacts are made from silver-plated copper, supporting high conductivity, low contact resistance and reliable electrical performance. This is especially important in solar PV systems where connection quality affects safety, efficiency and long-term system performance.
Certified for Professional Use
The SUNTREE MC4 Solar Connector Set is TÜV Rheinland type-approved, UL listed and EU-compliant, giving solar installers, EPCs, resellers and solar distributors confidence when sourcing certified balance-of-system components for European PV projects.
