Rich Solar 4/0 AWG Red and Black Pure Copper Inverter Battery Cables With 3/8 Inch Lugs

The Rich Solar 4/0 AWG Inverter Battery Cables Give Your Inverter a Pre-Terminated Pure Copper Connection to the Battery Bank

Rich Solar 4/0 AWG Inverter Battery Cables are a red and black pair of 4/0 AWG pure copper cables with 3/8 inch lugs fitted on both ends. They connect a battery bank directly to an inverter, and you can order them in 1 ft, 2 ft, 3 ft, 4 ft, 5 ft or 6 ft lengths.

Rich Solar lists them for solar systems, battery banks, RVs, marine setups and other DC applications. The PVC insulation is VW-1 rated, moisture resistant and rated for -40°F to 221°F, and the cables carry a voltage rating of up to 600V with UL certification.

Rich Solar 4/0 AWG Inverter Battery Cables Features

4/0 AWG Pure Copper Conductor

Each cable uses a 4/0 AWG pure copper conductor, which Rich Solar specifies for reliable power transfer in high-current applications.

Pre-Installed 3/8 Inch Lugs

The lugs come installed on both ends, giving you a secure connection point at the battery and at the inverter without any crimping on your part.

VW-1 Rated, Moisture-Resistant PVC

The insulation is PVC with a VW-1 flame rating. It resists moisture and is rated for operation from -40°F to 221°F.

Real-World Applications

RVs and boats. Connect a house battery bank to an inverter in an RV or on a boat, two of the uses Rich Solar names for this cable.

Solar and battery systems. Wire the inverter in a solar power system or a stand-alone battery bank with a short, pre-terminated run.

Practical Comparison

Pre-Terminated 4/0 AWG Cables Versus Cutting From Bulk Wire

Cutting bulk 4/0 AWG wire and fitting your own lugs means buying lugs and tooling and getting every crimp right. This pair arrives cut to length with 3/8 inch lugs already installed, so installation comes down to routing the cables and tightening the terminals.

Buyer Guidance

Match the Gauge to Your Inverter

Rich Solar doesn't give an inverter size range for the 4/0 AWG set. Use your inverter manual's cable and fuse requirements to confirm this gauge, and check that the inverter and battery terminals accept a 3/8 inch lug.

Plan for Weight and Routing

Rich Solar lists gross weights of 4 lb for the 2 ft set and 10 lb for the 6 ft set. Choose the shortest length that reaches, and route the cables so they don't pull on the terminals.

This May Be A Good Fit If

• Your inverter manual calls for 4/0 AWG cable
• You're wiring an RV, boat, solar system or battery bank
• Your terminals accept 3/8 inch lugs
• You need a pair between 1 ft and 6 ft long

Common Questions

Where Can I Use These Cables?

Rich Solar names solar systems, battery banks, RVs, marine installations and other DC applications.

What Temperature Range Is the Insulation Rated For?

The PVC insulation is rated for -40°F to 221°F.

Are Both Cables the Same Length?

Yes. Each option is a red and black set in the length you choose, with 3/8 inch lugs on both ends of both cables.
