About this product

What it is, and what it is for

A ready-made pair of 4 AWG battery-to-inverter cables, 8 ft (96 in) long, with 3/8″ ring lugs crimped and heat-shrunk on both ends. One red, one black, so the run from a battery bank to an inverter, busbar or disconnect is a bolt-up job rather than a crimping session.

  • 4 AWG, 8 ft (96 in) per cable, red and black pair
  • 3/8″ ring lugs at each end — fit the 3/8″ studs on most inverters, busbars and battery disconnect switches
  • For 12 V to 48 V battery systems; suits inverters up to about 3 kW at 48 V or 1.5 kW at 24 V over this length — check the continuous current in your inverter manual and fuse the battery side as it directs
  • Pairs with ROCKSOLAR LiFePO4 batteries, the 400 A busbar and the 1-2-Both-Off battery disconnect

Not sure which gauge you need? Cable size depends on the inverter's continuous current and the run length. Our engineers will check it for you.

Common questions

Before you order.

If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.

What if I'm not sure this is the right product?

Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
