Heavy-duty copper cables for connecting your inverter directly to your battery bank. Proper gauge inverter cables are critical for safe, efficient power delivery — undersized cables cause voltage drop, heat buildup, and can create a fire hazard. These cables come pre-terminated with ring lugs for 3/8 inch terminals.
Which Gauge Do You Need?
4AWG (5ft) — Suitable for inverters up to 1,000W. Good for light van builds.
1AWG (8ft) — Suitable for inverters up to 2,000W. Standard choice for full-time van builds.
4/0 AWG (5ft) — Suitable for inverters up to 3,000W. Required for high-draw cabin and heavy-use builds.
Always match cable gauge to your inverter's rated wattage. When in doubt, go one size heavier.
