PV Wiring 101

Unbound Solar carries high-quality PV wire, cables and solar panel connectors. The PV wire we stock is single conductor, insulated, and jacketed wire that is rated at 90° Celsius wet or dry (-40°C to 90°C), with a primary voltage of up to 2000V.

All current PV wires are fitted with MC4 1500V locking connectors and are compatible with almost all solar panels on the market.

Our PV wires are flame retardant (flame rated VW-1), sunlight resistant, moisture resistant, and crush resistant. They are rated for direct burial through a conduit or raceway in compliance with UL Standard 4703.

Wires and connectors are included in our complete system packages.
