Stand Alone Power Systems

Stand Alone Power Systems is a renewable energy business based in Toowoomba and the Southern Downs region of South East Queensland.

Founded and operated by Mark Wright, the business draws on over 20 years of experience in off-grid solar design and installation. Mark combines hands-on knowledge with technical expertise, having worked on hundreds of installations across rural Australia. His specialties include battery sizing, inverter selection, load profiling and generator integration.

Stand Alone Power Systems designs and installs custom off-grid solar systems tailored to the specific needs of rural and remote Queenslanders. Every solution is engineered to suit the client’s energy usage, appliances, location, and future plans — from remote cattle stations to off-grid homes and bush properties. Unlike generic solar kits, their systems are built for long-term reliability in harsh Australian conditions.

The team provides complete off-grid solutions, system upgrades, maintenance, technical support and remote monitoring. They use trusted components such as Victron Energy and Selectronic SP PRO inverter chargers, Pylontech LiFePO lithium batteries, and Tier 1 panels from Jinko and Trina — all selected for durability, expandability and proven performance.

Stand Alone Power Systems is committed to delivering energy independence with minimal generator use, high battery autonomy, and low maintenance requirements. Their philosophy is simple: if you’re relying on a generator every week, it’s not a true off-grid system. By oversizing solar arrays and designing for real-world challenges — including drought, dust, flooding, and overcast periods — they ensure reliable performance year-round.

The business is trusted by graziers, families, rural businesses, and individuals seeking self-reliance. Clients value their no-nonsense approach, technical accuracy, and personalised service that puts lifestyle and energy needs first. Whether it’s running a bore pump, charging an EV, or powering a workshop, Stand Alone Power Systems delivers off-grid systems that just work — quietly, efficiently, and without compromise.
