Solar connector QOLTEC MC4 1000V 30A, model 52598

QOLTEC MC4 solar connector (model 52598) is a single-contact photovoltaic cable connector rated for 1000 V and 30 A, designed for outdoor PV installations. It enables reliable electrical connection between solar panels, photovoltaic cables and system components while offering resistance to weather and mechanical stress. The connector is compatible with standard PV cables and is intended to simplify panel-to-panel and panel-to-inverter wiring in residential and commercial solar arrays.

Advantages

The connector provides stable electrical contact and a rated current capacity of 30 A at system voltages up to 1000 V, ensuring safe operation within typical PV system parameters. The weather-resistant housing prevents moisture ingress and reduces corrosion risk for long-term outdoor use. Its standard MC4-compatible form factor allows easy mating with widely used PV cables and components, reducing installation time and minimizing risk of mismatched parts.

Suitable for

• Connecting photovoltaic modules to each other in series or parallel
• Wiring solar panels to combiner boxes or inverters
• Outdoor photovoltaic installations requiring durable, weatherproof connectors
• Replacement of worn or damaged MC4-type connectors on standard PV cables

Key specifications

• Rated voltage: 1000 V (suitable for typical PV system voltages)
• Rated current: 30 A
• Contact type: single-pin MC4-compatible photovoltaic contact
• Environmental protection: weather-resistant housing for outdoor use
• Cable compatibility: standard PV cable diameters (MC4-compatible)

How to use

Strip the insulation of the PV cable to the recommended length, insert the conductor into the contact and crimp or solder according to installer practice and local regulations. Assemble the contact inside the connector housing and secure by snapping the housing closed until it locks. Ensure the male and female connectors click together firmly to create a secure electrical and mechanical connection. Verify polarity and correct mating before energising the circuit.

Usage recommendations

Use appropriate crimping tools or soldering equipment and follow national electrical codes and PV installation standards. Inspect connectors periodically for signs of wear, corrosion or loose connections and replace any damaged units. Avoid exceeding the specified voltage and current ratings and ensure correct cable cross-section for safe, reliable operation.
