Overview
2/0 AWG battery-to-inverter cables with 3/8" lugs, 1 to 6 ft
These Rich Solar 2/0 AWG battery cables connect a battery bank directly to an inverter. Each red and black pair uses pure copper conductors with pre-installed 3/8" lugs on both ends, and comes in lengths from 1 ft to 6 ft.
The pure copper carries high current reliably, and the lugs make installation quick and secure. The moisture-resistant PVC insulation is VW-1 flame rated, rated up to 600V and works from -67°F to +275°F.
