Fronius
Austrian-engineered, family-owned, the gold standard for Australian roofs.
Fronius has been building inverters in Austria for 30+ years and is widely regarded as the most reliable and longest-lived inverter brand in the Australian market. Active cooling keeps the unit running flat-out even on 40°C+ Victorian rooftops, the Solar.web monitoring platform is the most detailed in the industry, and Fronius products are designed to be repaired — not thrown away — with a strong network of factory-trained Australian technicians. The GEN24 hybrid range now adds battery-ready functionality to the same legendary build quality.
