Fronius Symo Advanced 22.7 Lite Powers Commercial Three-Phase Solar
The Fronius Symo Advanced 22.7-3 480 is a 22.7kW transformerless, three-phase string inverter for commercial and industrial solar on 480/277V WYE service. It takes up to 34kWp of PV on two MPPTs with a 1,000V maximum input, and integrated SunSpec Power Line Communication supports rapid shutdown. This Lite version ships without the Wi-Fi/datalogger communication card, so you can add a Fronius Datamanager 2.0 or use your own monitoring.
