Design Your Own System

Power Built Around Your Adventure

No two setups are the same. Whether you're building a weekend tourer, a full-time off-grid rig, a work ute or a serious marine electrical system, we'll help you design a solution that's tailored to your needs—not an off-the-shelf package.

At TideLine Power, we take the time to understand how you use your vehicle or vessel, what equipment you run, and how long you need to stay powered. The result is a reliable, efficient electrical system designed to perform when it matters most.

What We Offer

We provide custom electrical system design for:

  • 4WD touring vehicles

  • Canopies and service bodies

  • Caravans and camper trailers

  • Boats and marine applications

  • Portable power systems

  • Off-grid solar installations

  • Commercial and industrial DC systems

Whether you're starting from scratch or upgrading an existing setup, we'll work with you to create a system that suits your budget, power requirements, and future expansion plans.

Installation

Our service doesn't stop once your design is complete.

If you're tackling the installation yourself, we're here to help with technical guidance, wiring advice, and product support throughout the build. We want you to have the confidence that your system is installed correctly and performs exactly as intended.

If you'd prefer a professional installation, we’ve got you covered. Local to Mackay, QLD, with our very own workshop.

Depending on your project, your design package may include:

  • Complete system layout

  • Wiring diagrams

  • Equipment recommendations

  • Cable and fuse schedules

  • Product list

  • Installation guidance
