This partnership brings together two respected, third‑generation, family‑owned companies, each built on a strong foundation of engineering excellence, long‑term performance, and a shared vision for a renewable future. Master Instruments, founded in 1942, has evolved from a specialist manufacturer for the Australian Defence Forces into one of the country’s most trusted names in battery engineering, portable power solutions and technical expertise. Their deep history, values‑driven approach, and unwavering focus on quality closely mirror Fronius’ own heritage and commitment to delivering sustainable, long‑lasting energy solutions. This strong alignment in culture and purpose makes the partnership a natural and strategically meaningful fit.
“Fronius Australia is thrilled to partner with Master Instruments to deliver our full portfolio of advanced solar energy solutions to the Australian market. Master Instruments bring their expertise as a large battery developer and distributor and provides Fronius with new business opportunities across a number of sectors. The alignment of values, quality-focussed ethos and the desire to shape the Australian energy landscape with renewable energy solutions will be of benefit to Australian installers and consumers alike,“ said Dougal Gillman, Fronius Australia Distribution Manager.
For Master Instruments, the partnership represents an exciting evolution of its growing involvement in solar and renewable technologies. Their extensive battery development and distribution experience complements the Fronius portfolio and opens new opportunities across emerging and established sectors.
“Master Instruments’ strategic partnership with Fronius marks another important step in our commitment to supporting our clients on their electrification and decarbonisation journeys. The Fronius range of premium power conversion equipment is synonymous with world-leading safety, quality, and performance. With the recent addition of the new RESERVA battery series, clients can now realise genuine cost benefits by integrating energy storage into existing sites or through new installations paired with the latest Fronius Primo, Symo, and Verto Plus inverter series” said Phil Dunn, Master Instruments Managing Director
With the full suite of Fronius inverters, energy management tools, and storage technologies now supported by Master Instruments’ nationwide distribution network and technical capability, installers and integrators will benefit from streamlined access, improved product availability, and strengthened support channels across the country.
Together, Fronius and Master Instruments aim to empower Australian installers, integrators, and end‑users with premium‑quality solutions engineered for long‑term efficiency, sustainability, and return on investment. This partnership reflects our ongoing commitment to shaping a cleaner, smarter, and more resilient energy future for Australia.
