USE-2 (or RHW-2 / RHH) is a 600V stranded building wire rated for some of the toughest conditions in solar installation. It's the go-to choice for home runs from your combiner box to the charge controller or inverter.

USE-2 vs. PV wire: PV wire is more flexible and UV-rated for exposed rooftop use, but USE-2 is often preferred for underground trenching and long conduit runs where sunlight isn't a factor.

Available in: Multiple gauges (typically 10 AWG to 4/0) in black, red, and other colors.

Not sure if USE-2 meets your inspector's requirements for your specific run? Call us at 1-800-766-7644 – we've been running USE-2 since 2002.
