How to Choose

Size conductors to current and run length, not to convenience. Undersized cable is the most common cause of voltage drop and nuisance shutdowns on DIY installs. For DC battery runs, 4/0 AWG handles high-current inverter connections; 2 AWG and 4 AWG suit shorter or lower-current runs. On the PV side, 10 AWG copper covers most residential string runs. Always match connector brand across a junction — MC4-compatible is not the same as MC4.

Key Specifications Explained

  • Conductor gauge: 4/0, 2/0, 1/0, 2, 4, 6 and 10 AWG for battery and PV applications
  • Insulation: PV wire is rated for sunlight, wet locations and 90C conductor temperature
  • Connector standard: MC4 and MC4-Evo 2 — do not mate different manufacturers' connectors
  • Busbars: 300A and 600A with covers for clean multi-battery parallel connections
  • Length: Pre-terminated sets from 12 inches to 96 inches, and bulk spools to 1000 ft

Brands We Carry

Pacific Coast Wire, Stäubli (the original MC4 manufacturer), QuickCable, Winar Connection, HEYCO and Ilsco.

Frequently Asked Questions

Can I mix MC4 connectors from different brands?

No. Cross-mating is a known arc and fire risk and it voids listings. Use the same manufacturer on both halves of every connection.

What gauge for my battery to inverter run?

Follow the inverter manufacturer's table. As a guide, a 12kW inverter typically calls for 4/0 AWG on runs under six feet.

Is PV wire the same as THHN?

No. PV wire is rated for direct sunlight exposure and wet locations. THHN is not and will degrade outdoors.
