The Fronius Symo is a family of Fronius inverters, and the 480 V models include the Symo 15.0-3 480, 17.5-3 480 and 24.0-3 480. The firmware changelog also covers the Symo 3.0-3-S to 4.5-3-S, 3.0-3-M to 8.2-3-M and 10.0-3-M to 20.0-3-M models. Data communication uses Fronius Solar Net, which is the factory-set protocol type, and Interface is the other option. The Interface protocol type only works without a Fronius Datamanager card, so take out any installed Datamanager card before you use it. Status code 103 means the AC voltage is too low, and status code 106 means the AC frequency is too low. The operating instructions include a section on FCC and RSS compliance.
