PV WIRE AND ACCESSORIES

Multi-Contact Cables & Connectors

The Multi-Contact Solarline family of connectors as well as the Helios 4 delivers a flexible system solution for time-saving, dependable series cabling of solar modules. All module manufacturers supply their grid-tie modules with pre-assembled output cables, tested and ready for connection. This saves considerable time during an installation and greatly increases reliability over wire junction boxes. These cable couplers are fully touch-protected and designed for up to 1000 volts and 30 amps. They are also waterproof. For parallel connection of modules in 12- to 48-volt systems, Multi-Contact makes branch connectors for use with currents up to 30 amps.

For the past few years, modules have come with Multi-Contact Solarline 1 connectors which have a soft rubber insulator. In 2007, PV manufacturers began switching to Multi-Contact Solarline 2 locking connectors to meet future electrical PART NUMBER requirements.

The Multi-Contact plug-and-play connector system allows for the PV arrays to be pre-assembled and pre-wired in the shop or on site. We stock both styles of connectors for use with 10 AWG or 12 AWG USE-2 stranded wire. Proper crimping to the wire and insulator assembly requires special tools. We stock standard lengths of assembled cables and adapters to go between Solarline 1 and Solarline 2 connectors and the tools required for on-site assembly of cables.

MC3 Solarline 1 & MC4 Solarline 2 Array Output Cables
Use these output cables between PV arrays with Multi-Contact cable outputs, and junction boxes or grid-tie inverters. Both the original Solarline 1 and the new Solarline 2 have a male connector on one end and a female connector on the other end. 

Use them to extend module output cables or cut anywhere along the wire to obtain the needed length of male and female cable to run from the ends of a module string to a combiner box or to an inverter.

For example, if you need a 30' male and a 20' female, order a 50' cable.

Made with black #10 AWG USE-2 sunlight-resistant cable.

Waterproof Strain Reliefs

Use the 1/2" threaded connectors to provide a waterproof entrance or exit for wiring on PV module junction boxes, outdoor combiner boxes, and junction boxes. Use the 3/4" connector for larger cables up to 5/8" diameter. They are made of Nylon with Buna-N seals and are resistant to salt water, weak acids, weak alkalis, alcohol, ether, esters, ketones, and mineral, animal and vegetable oils. The threads are 1/2" or 3/4" NPT. Non-corrosive and suitable for direct burial installations.

The oval-hole 1/2" strain relief works great for two-conductor TC cable used for module interconnects and for PV outputs or for UF cable. The two-hole 1/2" connector is designed for use with two #10 or #12 type USE conductors like the ones used for Multi-Contact PV output cables. UL Listed. Suitable for use in NEMA 4, 6 and 12 applications.
