This DC photovoltaic adapter cable set consists of two adapter cables, one equipped with an MC4 male connector and the other with an MC3 female connector, both terminated with cylindrical DC connectors on the device side. The cables are clearly identified by color coding—red for positive (+) and blue for negative (−) polarity—to prevent wiring errors during installation.

Designed for DC-side connections in photovoltaic systems, these adapter cables are used to interface PV strings with inverters, testing instruments, or compatible DC devices. They provide a secure and reliable electrical connection, suitable for both permanent installations and temporary diagnostic setups.

The MC4 connectors feature an integrated safety locking system and are marked with the warning “STOP / Do not disconnect under load”, ensuring safe operation and compliance with photovoltaic installation standards.

These adapter cables are suitable for professional use in residential, commercial, and industrial photovoltaic installations, as well as for maintenance, commissioning, testing, and troubleshooting of solar power systems.
