Fronius

Fronius is an inverter manufacturer. Its parent company, Fronius International GmbH, lists addresses in Pettenbach and Wels, Austria. In the United States it operates as Fronius USA LLC, Solar Electronics Division, based in Portage, Indiana. Contact details for its subsidiaries and its Sales & Service Partners are listed on the Fronius contact web page. The Galvo and Primo 208-240 inverters carry certification records listing them as utility-interactive inverters certified to U.S. standards. The Primo models are described as transformerless. Fronius developed Fronius Solar Net, a ring-topology data bus that connects one or more inverters to system add-ons. Each inverter on the bus needs its own unique number. The Fronius Datamanager 2.0 monitors the system, connects to Fronius Solar.web and allows inverter control over Modbus TCP/RTU. The Fronius Solar.start app makes first commissioning easier.
