What's Included in Your Charging Install
Every charging and inverter system is designed around your setup and installed to a high standard using proven components from Victron, REDARC and Enerdrive. Built for real-world off-grid use.
DC-DC Battery-to-Battery Chargers
Charges your auxiliary battery from the alternator without damaging modern smart-alternator vehicles. Essential for LiFePO4 batteries and any vehicle made after 2015.
MPPT Solar Charge Controllers
Maximises the power harvested from your solar panels and converts it efficiently into charge for your batteries. We install Victron SmartSolar and Redarc MPPT controllers to suit any panel size.
Pure Sine Wave Inverters
Converts 12V & 24V DC battery power into clean 240V AC power, safe for laptops, TVs, power tools, microwaves, and sensitive electronics. We only install pure sine wave; we don't fit modified sine wave inverters.

All-in-one units like the Victron MultiPlus handle inverting, mains charging, and power transfer in a single box. Ideal for caravans with shore power hookups that also need off-grid capability.

Shore Power & Mains Charging

Wiring, Fusing & Cable Sizing
Every charging component gets the right cable sizing, inline fusing, and tidy routing. All wiring is rated to spec, heat-shrink terminated, and labelled, no undersized wire, no loose connections.

What Our Customers Say
Nathan installed 2 x 12 volts systems, one in our Motorhome and one in the trailer. Not only is the system fantastic and we never have to worry about our power, but he also fixed faults we had with our old system. The batteries have 7 years warranty, the upgrade to our panels keep the batteries topped up which really helps on cloudy and rainy days. We recommend Nathan to everyone, and he is so easy to deal with.

10/10 for everything! Nathan drove to woop woop to install our bushman fridge, new battery system & fans. Last week in 42 degrees our fridge was lovely and cold and the fans were a godsend! We will use Coast Custom 12 Volt for anything we need in our offgrid set up!
