The Fronius Symo Advanced 20.0-3 480 is a transformerless three-phase string inverter for commercial rooftops and carports on 480 V three-phase service. Two MPP trackers, the Dynamic Peak Manager for shade-tolerant tracking, and the SnapINverter hinged mount keep design and installation simple, while the NEMA 4X enclosure allows indoor, outdoor or near-flat mounting (a Fronius Shade Cover is required below 15° tilt). This is the Lite configuration (part number ending 801), which ships without the Datamanager card; add a Fronius Datamanager 2.0 for Wi-Fi/Ethernet monitoring on Solar.web. Built-in power line communication supports SunSpec Rapid Shutdown.
Highlights
- Dual MPPT with Dynamic Peak Manager shade management
- SunSpec Rapid Shutdown via integrated power line communication
- Integrated AFCI, DC disconnect and ground-fault protection
- SnapINverter mounting and variable-speed fan cooling
