Renogy 8ft 4AWG Copper Tray Cable (3/8″ Lug)

Renogy 8ft 4AWG Copper Tray Cable (Battery to Charge Controller)

The Renogy 8ft 4AWG Copper Tray Cable is the heavy-gauge choice for connecting your battery and charge controller in higher-current systems. A battery ring terminal on one end bolts straight to your battery, while exposed stranded wire on the other end leads directly into your charge controller’s terminal — no extra adapters needed. With a substantial 21.15mm² cross-section and pure copper construction, it handles the demands of high-output controllers with ease.

Effortless Battery-to-Controller Connection

Specialised with a 3/8″ round centre-hole battery ring on one end for effortless connection to your battery, and exposed stranded wire on the other to feed straight into the charge controller, this cable makes system setup simple and clean.

Heavy-Gauge, High-Current Capacity

At 4AWG (21.15mm²) with a 95A NEC maximum current rating, this is the heaviest of Renogy’s tray cable gauges — recommended for high-output controllers such as the Rover 60A. Match the gauge to your system’s current and your controller’s terminal size for a safe, efficient connection.

TÜV-Listed for Solar Use

The cable meets TÜV standards for PV solar applications. UV-resistant and waterproof, it produces optimal power output even in high-temperature conditions, and is rated to 1000V — dependable for demanding outdoor installations.

Pure Copper, Reliable Quality

Pure oxygen-free copper wiring ensures maximum conductivity, while tin-plated copper terminals minimise corrosion for a long-lasting connection. Heat-shrink tubing insulates the wire, adding abrasion resistance and electrical safety.

Choosing the Right Gauge

Match the cable gauge to the current your system carries and your charge controller’s terminal size. As a general NEC guide: 4AWG (95A) suits the Rover 60A; 8AWG (55A) suits the Rover 30A/40A, Adventurer 30A, and Wanderer 30A; 10AWG (30A) suits the Rover 20A and Voyager 20A; and 12AWG (20A) suits the Wanderer 10A and Voyager 10A. Always check your charge controller’s manual for the compatible wire gauge range. For overcurrent protection, fit a fuse or breaker between the charge controller and battery, sized to match the controller’s amperage.
