⚡ Designed for 1500W Inverter Systems

High-power inverters can draw substantial current from a 12V battery system, making correctly sized battery cable and circuit protection essential.

This kit is designed primarily for 1500W 12V inverter installations, providing the heavy-duty cable and fuse protection required for a clean battery-to-inverter connection.

It is ideal for powering inverter systems installed in:

• 4WDs
• Caravans
• Camper trailers
• Vehicle canopies
• Touring vehicles
• Lithium battery systems
• AGM battery banks
• Off-grid solar systems
• Marine installations
• Auxiliary power systems

🛡️ MEGA Fuse Protection

The positive battery cable in an inverter installation should be protected by an appropriately rated fuse installed close to the battery supply.

This kit includes a heavy-duty MEGA fuse holder and compatible fuse option, helping protect the battery cable and electrical system against excessive current and short-circuit faults.

Always select the fuse rating according to:

• Inverter manufacturer's requirements
• Cable current capacity
• Battery system voltage
• Cable length
• Expected continuous current
• Installation conditions

📏 Select the Cable Length to Suit Your Installation

Choose the cable length that best suits the distance between your battery bank and inverter.

For high-current 12V inverter installations, keeping the battery cables as short as practical helps reduce voltage drop and improves inverter performance.

Both Red positive and Black negative 2 B&S cable are supplied to provide a complete battery-to-inverter cable pair.

🚙 Ideal for 4WD, Caravan & Off-Grid Systems

This 2 B&S inverter wiring kit is particularly suited to:

• Caravan inverter installations
• 4WD canopy systems
• Camper trailer power systems
• Dual battery installations
• Lithium battery banks
• AGM auxiliary batteries
• Pure sine wave inverters
• Solar battery systems
• Camping and touring setups
• Off-grid electrical systems

🔧 Supplied for Custom Termination

The cable and termination components are supplied so the wiring can be cut and terminated to suit the exact layout of your installation.

This is particularly useful in custom 4WD, caravan and canopy builds where battery and inverter positions vary between installations.

🧰 Installation Difficulty

🟠 3/5 – Intermediate

Installation requires correctly terminating heavy-duty battery cable, installing appropriate fuse protection and securely connecting the battery and inverter.

Professional installation is recommended if you are unfamiliar with high-current DC electrical systems.

  • ⚠️ Important Inverter Sizing Information

    This kit is designed primarily for 1500W inverter installations on 12V systems.

    It may suit some higher-output applications depending on system voltage, cable length, inverter efficiency, fuse rating, installation conditions and the inverter manufacturer's specified cable requirements.

    For higher-powered 2500W–3000W 12V inverters, we recommend stepping up to a larger battery cable such as our 00 B&S 3000W Inverter Wiring Kit.

    Always follow the inverter manufacturer's cable size and fuse recommendations.
