4 AWG Battery/Inverter Cable

Assembled in our Northern California warehouse, this 4 AWG battery and inverter cable is built for dependable power transfer in solar, battery storage, UPS, and industrial electrical systems. Cable length is measured from the center of each lug stud hole to ensure accurate 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 long-term 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) equipment per UL 1778. It is also suitable for transformers, switchboards, control panels, inverter connections, battery banks, and general power distribution applications.
