Selectronic SP Pro

Australian SOLAR made excellence

Selectronic SP ProFounded in 1964 Selectronic Australia quickly established itself as a major manufacturer of custom made transformers and inductors for the local electronics industry. In 1981 the company’s electronics products division was established to meet a need for quality power conversion products in the emerging renewable energy market.

At a time when power inverters were new and renewable technologies were just starting to emerge, Selectronic Australia became an innovator in the field by producing its first power conversion product – a 360 Watt DC to AC modified square wave inverter.

Driven by demand from the Solar industry and a passion for green energy, Selectronic Australia expanded its product offering. In 1994 the company produced one of the world’s first true sine wave inverters. This brand new technology overcame the shortcomings of the modified square wave products and revolutionised the quality of the customer’s power in Renewable Energy systems.

Selectronic Australia has grown through a philosophy of providing products and solutions that focus on the customer needs and today this second generation family company manufactures a world class range of highly innovative and functional interactive inverters. Using advanced technologies, Selectronic Australia’s products form the heart of efficient, cost effective storage based renewable energy systems including Solar Hybrid and Off Grid systems perfect for the Sunshine Coast.

The Selectronic SP PRO comes in a range of sizes from the small 3kW 24 volt unit all the way up to the 20kW 120 volt unit. The most popular unit for off grid or standalone solar power systems is the SP PRO SPMC481-AU 5kW 48 volt as it offers superior performance and unparalled performance.
