## Summary description

QOLTEC MC4 solar connector (model 52597) is a single-pole PV connector rated for 1000 V and 20 A, designed for connecting photovoltaic panels and components. It provides a secure, weather-resistant electrical connection compatible with MC4-type systems. Suitable for residential and small commercial solar installations where reliable DC connections and easy assembly are required.

## Long description

QOLTEC MC4 1000V 20A solar connector (model 52597) is a single-pole photovoltaic connector engineered for safe DC interconnections in PV systems. Designed to mate with standard MC4-type components, it provides a weather-resistant housing and secure locking mechanism for reliable performance in residential and small commercial solar installations. The connector supports voltages up to 1000 V and continuous current up to 20 A, facilitating straightforward panel-to-panel, panel-to-junction box or panel-to-inverter wiring where MC4 compatibility is required.
Advantages
The QOLTEC MC4 connector offers a compact, UV-stabilized enclosure and an IP-rated sealing system that protects contacts from moisture and dust. Its snap-lock design ensures stable mechanical retention and quick assembly without specialized tools, while the contact materials provide low electrical resistance for efficient power transfer. The connector’s compatibility with common MC4 systems simplifies integration with existing PV components and reduces installation time.
Suitable for
Connecting photovoltaic modules in residential rooftop arrays
Wiring small commercial and off-grid solar systems
Extension and repair of existing MC4-compatible PV cabling
Interfacing panels with junction boxes, combiner boxes, and inverters
Key specifications
Poles: single-pole (positive or negative contact)
Maximum voltage rating: 1000 V DC
Continuous current rating: 20 A
Environmental protection: UV-stabilized housing and weather-resistant seal
Connection type: plug-and-socket MC4 compatible with snap-lock mechanism
Cable compatibility: typical PV cable cross-sections for 20 A operation (refer to local wiring standards for exact conductor size)
How to use
Strip the photovoltaic cable to the recommended conductor length, insert the conductor into the contact insert and crimp or tighten according to the connector’s assembly method. Ensure the contact is fully seated inside the housing before locking the snap mechanism. Mate the male and female halves until an audible click confirms engagement, and verify polarity before energizing the circuit. Follow local electrical codes and safety procedures when working with DC PV circuits and isolate circuits before making or breaking connections.
Usage recommendations
Use the connector within its rated voltage and current limits and inspect seals and contacts periodically for signs of corrosion or mechanical wear. For runs subject to high currents or long cable lengths, consult wiring tables to select appropriate conductor sizes and minimize voltage drop. When installing outdoors, route and secure cables to avoid strain on the connector housing.
