Rich Solar 6 Gauge (AWG) Black and Red Pure Copper Inverter Battery Cables

The Rich Solar 6 Gauge (AWG) Black and Red Pure Copper Inverter Battery Cables Make Clean Battery Connections for Smaller Inverters

The Rich Solar 6 Gauge (AWG) Black and Red Pure Copper Inverter Battery Cables are a matched red and black pair of 6 AWG cables with 5/16 inch lugs pre-installed on both ends. They are made to connect a battery bank directly to an inverter, and they also suit battery-to-battery, bus bar and other heavy DC connections in solar, RV and marine systems.

Rich Solar builds the cables with 100% pure copper conductors and flexible PVC insulation that is VW-1 flame rated and moisture resistant. Choose from nine lengths, from 1 ft to 10 ft, so you can keep each run as short and tidy as possible.

Rich Solar 6 Gauge (AWG) Black and Red Pure Copper Inverter Battery Cables Features

100% Pure Copper Conductors

Pure copper conductors provide reliable power transfer and flexibility, so the cables route easily around battery boxes and through tight compartments.

Pre-Installed 5/16 Inch Lugs

Both ends come with 5/16 inch lugs already installed. You can bolt the cables to inverter terminals, battery posts and bus bars without crimping your own lugs.

Durable PVC Insulation

The flexible PVC jacket is VW-1 flame rated and moisture resistant. Rich Solar lists an operating range of -67°F to 275°F and a voltage rating of up to 600V.

Red and Black Pair

Each set includes one red cable for positive and one black cable for negative, which makes polarity easy to identify during installation and service.

Nine Length Options

Lengths run from 1 ft to 10 ft. Short 1 ft and 1.5 ft sets work well for linking batteries side by side, while longer sets reach an inverter mounted on a nearby wall or shelf.

Real-World Applications

Inverter to battery. Connect an off-grid or RV inverter directly to its battery bank.

Battery banks. Link batteries in series or parallel with short matched cables.

RVs and vans. Wire a house battery bank to an inverter, bus bar or shunt.

Marine systems. Make heavy DC connections in battery compartments with moisture-resistant insulation.

How It Compares to Common Alternatives

Versus making your own cables. Pre-installed lugs save you from buying a heavy-duty crimper and lugs, and they reduce the risk of a poor crimp at a high-current connection.

Versus 4 AWG cable. The 6 AWG cable is lighter and easier to route. 4 AWG is thicker, with less voltage drop for larger inverters and longer runs.

Versus controller-to-battery cable. Solar charge controllers carry much less current than inverters, so they use lighter 8 or 10 AWG cable. Inverter connections need heavy cable like this.

Is This Cable the Right Fit

• Gauge. Use the cable size your inverter manual specifies for its power rating and your battery voltage.
• Lug size. Both ends have 5/16 inch lugs. Check that they fit your inverter and battery terminals.
• Length. Keep inverter cables as short as practical, since longer runs add voltage drop.
• Fusing. Add a properly sized fuse, such as an ANL fuse, between the battery and the inverter.

This may be a good fit if

• You are connecting an inverter to a battery bank
• Your terminals take 5/16 inch lugs
• You want pure copper cable with lugs already installed
• You want matched red and black cables in a set length

Common Questions

Is the Length Per Cable?

Yes. Each option includes one red and one black cable, and each cable is the length you select.

What Size Are the Lugs?

Both ends of each cable have 5/16 inch lugs.

Which Inverter Size Needs 6 AWG Cable?

It depends on the inverter's power, your battery voltage and the cable length. Follow your inverter manual's cable size chart, and contact our team if you are unsure.
