Founded in 1964, Selectronic Australia quickly established itself as a major manufacturer providing products and solutions that focus on the customer needs. Selectronic offers a world class range of highly innovative and functional interactive solar inverters.


The highly successful SP PRO Series II has been expanded to include the SP PRO GO Series designed specifically for the Solar Hybrid (grid connect) market. They have a Grid Feed-In Power Rating, independent of the inverter rating, to meet the requirements of the utility while still providing for the consumer’s power needs.

Grid Feed and Grid Battery Backup in one unit

Add the versatility of energy storage to your Grid Connect solution using the SP PRO as a low voltage grid feeding inverter that puts you in control of your grid system.

Engineering Excellence

Drawing on our inverter experience since 1981, the SP PRO contains features not found in other inverters. With highly accurate thermal power management and high speed digital signal processing, the SP PRO sets new standards for reliability, power density and flexibility.
