Xantrex DC Battery Cables (4G) + Fuse M-Kit

Setting up your inverter system doesn't have to involve wrestling with raw cables and guessing at proper fusing. The Xantrex DC Battery Cables (4G) + Fuse M-Kit streamlines the process, delivering pre-assembled components that connect your inverter directly to the battery bank with confidence. Ideal for off-grid adventures, RV living, or marine applications, this kit ensures reliable power flow while prioritizing safety against overloads and short circuits.

Key Features That Make Installation a Breeze

Engineered for hassle-free setup, these cables come ready-to-use with professional-grade terminations. No need for specialized tools or crimping expertise—just bolt them in place. The 2AWG gauge strikes the perfect balance for handling the current demands of mid-range inverters without excessive voltage drop, keeping your system efficient even over the full 8-foot length.

• Robust 2AWG Cables: Eight feet of flexible, pure copper wiring rated for high amperage, minimizing resistance and heat buildup.
• Integrated Fuse Block: Class T fuse holder provides superior protection with fast-acting response to faults, safeguarding your batteries and inverter.
• Pre-Terminated Ends: Lugs sized precisely for standard battery posts and inverter terminals, reducing connection errors.

Perfect Match for Your Power Needs

Designed specifically for inverters in the 900-1300W range, this kit supports systems like those powering household appliances during blackouts or running tools at remote job sites. It pairs seamlessly with deep-cycle lead-acid or lithium batteries, ensuring stable DC input for peak performance. Users often note how the extra cable length allows for clean routing around obstacles in tight battery compartments, preventing strain on connections.

Step-by-Step Installation Guide

Follow these straightforward steps to get your system up and running in under an hour:

1. Turn off all power sources and disconnect the battery negative terminal first for safety.
2. Mount the fuse block near the battery positive terminal, ideally within 18 inches to comply with best practices for DC fusing.
3. Attach the positive cable from battery to fuse block input, then fuse block output to inverter positive terminal.
4. Route the negative cable directly from battery to inverter, securing with zip ties to avoid chafing.
5. Install the appropriate Class T fuse (sold separately, sized to your inverter's max DC amps).
6. Reconnect battery negative last, then test for proper voltage at the inverter.

Pro Tip: Always double-check polarity—red to positive, black to negative—to avoid damaging your equipment. In humid environments, apply dielectric grease to terminals for corrosion resistance.

Safety and Longevity Built In

One common pitfall in DIY inverter installs is undersized wiring or skipped fusing, leading to melted cables or battery fires. This kit eliminates those risks with oversized conductors and a dedicated fuse mount that handles surge currents far beyond typical loads. Over time, the tinned copper strands resist oxidation, extending service life in salty marine air or dusty solar setups. Regular inspections for loose connections keep everything humming smoothly.

Real-World Advantages Over DIY Alternatives

While piecing together cables from a hardware store might save a few bucks upfront, the time spent measuring, cutting, and crimping often leads to suboptimal results. This pre-made kit delivers factory-quality connections that outperform home efforts, backed by Xantrex's reputation for rugged marine-grade components. Boaters and van-lifers rave about the plug-and-play simplicity, freeing them to focus on the journey rather than troubleshooting.
