PV Wire & Connectors

PV Wire & Connectors – Solar Array Wiring Components

The PV wire and connectors category provides specialized wiring and connection components designed specifically for PV (Photovoltaic) applications. Quality PV wire features UV-resistant insulation, temperature ratings up to 194°F wet and 302°F dry, and moisture resistance for decades of outdoor exposure.

Modern MC4 connectors deliver weatherproof, tool-free connections between solar panels and system wiring, ensuring reliable electrical contact during the system’s lifespan.

Wire options include UL-listed PV wire in various AWG (American Wire Gauge) sizes from 14AWG to 2AWG, with black and red insulation for positive and negative identification. Single-conductor wire accommodates panel to panel runs, while bundled pairs simplify installation.

Connector options include MC4 male and female pairs, Y-branch connectors for parallel string connections, T-branch connectors for mid-string taps, and extension cables with pre-installed connectors for panels and combiners.

Featured products include genuine MC4 connectors from Staubli. Crimping tools ensure proper mechanical and electrical connections, while disconnect tools enable safe connector separation during maintenance.

Inline fuse holders provide string-level protection. Wire management clips secure cables to racking systems to prevent wind damage and maintain organized installations.

Wire and connector options include array voltage, string current, distance from panels to combiner or charge controller, and environmental exposure conditions.
