Solarstekker QOLTEC MC4 1500V 30A – fotovoltaïsche kabelstekker voor buiten

QOLTEC MC4 1500V 30A solar connector is a photovoltaic cable connector engineered for outdoor solar panel systems. It supports voltages up to 1500 V and continuous currents up to 30 A, providing a weather-resistant and secure electrical joint between PV modules, extension cables, and balance-of-system components. The connector is compatible with common PV cable diameters and is intended for use in array assemblies, repairs, or system expansions where a reliable DC connection is required.

Advantages

The connector offers reliable waterproof and UV-resistant sealing suitable for long-term outdoor exposure. Its standardized MC4-style design ensures consistent mechanical fit and low contact resistance for efficient power transmission. Push-fit locking simplifies assembly without special tools, and the robust housing material resists temperature fluctuations and environmental stress typical in rooftop and ground-mounted installations.

Suitable for

• Connecting solar modules in series or parallel within PV arrays
• Extending or repairing photovoltaic cable runs
• Retrofit and new photovoltaic installations on residential and commercial roofs
• Ground-mounted solar farms and outdoor inverter connections

Key specifications

• Maximum voltage rating: 1500 V DC
• Maximum continuous current: 30 A
• Compatibility: standard MC4-style photovoltaic cables and contacts
• Environmental protection: weatherproof and UV-resistant housing
• Operating temperature range suitable for outdoor PV installations
• Cable cross-section compatibility suitable for typical PV conductors

How to use

Strip the insulation of the PV cable to the required length, insert the conductor into the contact, and crimp or assemble according to the connector's mechanical contact method. Push the male and female halves together until the locking tab engages, ensuring a secure electrical and mechanical connection. Verify polarity before connecting strings to inverters or junction boxes and perform a visual inspection of seals and locking mechanisms after assembly.

Recommendations

Use connectors that match the cable cross-section and follow local electrical codes and manufacturer installation instructions. Periodically inspect outdoor connections for seal integrity and signs of wear; replace connectors that show damage or elevated contact resistance. For high-voltage PV systems, ensure proper safety procedures and qualified personnel perform installation and testing.
