Renogy Battery Inverter Cables for 3/8 in Lugs

The Renogy Battery Inverter Cables for 3/8 in Lugs Give You a Color-Coded Pair to Connect an Inverter to a Battery Bank

The Renogy Battery Inverter Cables for 3/8 in Lugs are a red and black pair with 3/8 in ring terminals at both ends. Renogy designed them to run between a power inverter and a battery bank. You can choose 5 ft 4 AWG, 8 ft 1 AWG, 5 ft 2/0 AWG or 5 ft 4/0 AWG.

They suit anyone wiring an inverter whose terminals take 3/8 in lugs, such as RV, van, boat and off-grid builds. Match the gauge and length to your inverter and your fusing plan.

Renogy Battery Inverter Cables for 3/8 in Lugs Features

Color-Coded Red and Black Pair

Red and black cables make it easy to identify positive and negative at both the inverter and the battery. That helps you avoid reversed polarity.

Stainless Steel Ring Terminals

Each cable has a ring terminal for a 3/8 in lug at each end, so there is nothing to crimp. Renogy says the 8 ft 1 AWG cables have heat shrink on both ends.

Flexible Stranded Conductors

Renogy lists stranded conductors that can be bent to suit your layout. The 4 AWG and 1 AWG options use tinned copper with Class K 30 AWG bare copper stranding.

Tough, Flame Retardant Jacket

Renogy lists a flame retardant polyvinyl chloride compound. The 8 ft 1 AWG cables use UL-certified Cobra X-Flex, which Renogy says resists moisture, abrasion, acid, diesel fuel and oil.

Real-World Applications

Inverter to battery bank. Link an inverter to a single battery or a battery bank, keeping the run short.

Replacing worn cables. Swap in a ready-made pair with the right terminals when old cables are damaged or the wrong size.

Choosing a size. Use the thicker gauges when your inverter draws more current. Renogy lists 230A as the maximum operating current for the 5 ft 4/0 AWG option.

Practical Comparison

Battery Inverter Cables Versus Cutting Your Own Cable

Cutting and crimping your own cable takes cable, lugs, heat shrink and a crimper. These cables come with terminals attached in set lengths.

4 AWG, 1 AWG, 2/0 AWG and 4/0 AWG Options

The 4 AWG pair is the thinnest and lightest, and 4/0 AWG is the thickest. A thicker gauge carries more current over the same distance. Pick the gauge that fits your inverter and its fuse.

Buyer Guidance

Size and Length

Check your inverter manual for the cable gauge and fuse it calls for, then pick the matching option. Keep the cables as short as practical, since long runs add voltage drop. If you are unsure, ask a qualified electrician.

Lug Size

These cables fit 3/8 in lugs. Make sure your inverter and battery terminals are sized for 3/8 in lugs before ordering.

This May Be A Good Fit If

• Your inverter and battery take 3/8 in ring lugs
• You want ready-made, color-coded cables
• You need a 5 ft or 8 ft run
• You want a heavy gauge up to 4/0 AWG

Common Questions

Do I Get One Cable or Two?
