Fronius Symo
The Fronius Symo is a three-phase inverter available in powers ranging from 3 to 20 kW. Thanks to SuperFlex Design, an inverter in the Fronius Symo range is the ideal choice for solar installations on unconventionally-shaped roofing. The range includes string and micro inverters.
String inverters convert power generated from all of the solar modules in the system at the same time. Details of the Fronius Symo string inverters can be found below.
