The 1000V MC4 Connectors are robust, high-voltage-rated direct current (DC) connectors specifically designed for solar photovoltaic (PV) systems. These male-female plug pairs are used to connect solar panels, extension cables, and combiner boxes, providing a secure and weather-resistant electrical connection.
Widely used in off-grid and grid-tied solar applications, MC4 connectors simplify installation and ensure consistent power transmission in high-temperature, high-UV, and outdoor environments. Their locking design prevents accidental disconnections, making them ideal for rooftop, ground-mounted, and commercial PV systems.

High Voltage Handling
Suitable for 1000V DC applications, supporting high-efficiency solar modules and long string layouts.
Secure Locking Mechanism
Snap-lock design ensures a reliable, vibration-resistant connection that won't loosen over time.
Weatherproof Protection
IP67-rated design provides excellent sealing against dust, moisture, and rain for outdoor use.
Quick and Easy Installation
Push-fit connectors and standard crimping make it easy to assemble on-site without specialized tools.
UV and Heat Resistant
Designed to withstand prolonged sun exposure and extreme temperatures common in Kenyan environments.
Universal Compatibility
Fits most solar panels, inverters, and extension cables using MC4 standards.
Safe and Durable
Flame-retardant materials and corrosion-resistant contacts ensure safe, long-term operation.
Strip and crimp the solar cable with the MC4 contact pin using a compatible crimping tool.
Insert the contact pin into the MC4 housing until it clicks into place.
Tighten the sealing nut at the back of the connector to secure the cable and maintain the IP67 rating.
Repeat for both male and female ends.
Push-fit male and female connectors together until they lock audibly. Use an MC4 tool to unlock if needed.
