Multi-Contact
Cables and Connectors
The Multi-Contact Solarline family of connectors 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-Concaaact makes branch connectors for use with currents up to 30 amps.
For the past few years, modules have come with Mult-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 code 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 Solarline2 connectors and the tools required for on-site assembly of cables.
MC3 Solarline 1 Array Output Cables
These cables have the old style Multi-Contact soft rubber connectors on each end. Use these output cables between PV arrays with Multi-Contact cable outputs, and junction boxes or grid-tie inverters. They 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 len gth of male and female cable to run from the ends of a module string to a combiner box or to an inverter. Made with black #10 AWG USE-2 sunlight-resistant cable.

These cables have a neutral male at one end and a negative female at the other so they can be used to connect to a roof-top combiner. Made with black #10 AWG USE-2 sunlight-resistant cable.
MC4 Solarline 2 Array Output Cables
These cables have the newer, snap-together Multi-Contact hard plastic connectors on each end. Use these output cables between PV arrays with Multi-Contact caable outputs, and junciton boxes or grid-tie inverters. The new Solarline 2 cables 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.
MC4 Solarline 2 PV-Wire Cables
These cables have the newer, snap-together Multi-Contact hard plastic connectors on each end and are made with PV-Wire that has an extra layer of insulation for use on ungrounded arrays in conjunction with transformerless inverters. This type of wire is required to meet the 2008 NEC if you are using a transformerless inverter.
