3/0 Battery/Inverter Cable

Assembled in our Northern California warehouse, this 3/0 battery and inverter cable is designed for high-current power distribution in solar, battery storage, UPS, and industrial applications. Cable length is measured from the center of each lug stud hole for precise installation.

Each custom assembly is manufactured using All-Flex fine-stranded Class K 30-gauge bare copper cable and terminated with Quick Cable Max lugs, secured with heavy-walled adhesive-lined heat shrink for maximum durability and corrosion resistance.

Designed to meet or exceed Underwriters Laboratories (UL) and National Electrical Code (NEC) requirements, this cable is recommended for internal wiring of uninterruptible power supply (UPS) systems per UL 1778. It is also suitable for transformers, switchboards, inverter connections, battery banks, control panels, and high-demand electrical systems.
