4/0 Battery/Inverter Cable

Assembled in our Northern California warehouse, this 4/0 battery and inverter cable is built for high-current power distribution in solar, backup power, and industrial applications. Cable length is measured from the center of each lug stud hole to ensure precise fitment.

Each custom assembly is manufactured using All-Flex fine-stranded Class K 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 use in transformers, switchboards, control panels, inverters, battery banks, and other high-demand electrical systems.
