The Fronius Symo 15.0-3 208 is a compact transformerless three-phase inverter sized for small commercial systems on 208 V wye service. A single high-current MPP tracker (50 A usable) with a 325–850 V MPP window accepts large parallel string counts, and integrated 6+/6− string fuse holders reduce the need for an external combiner. The SnapINverter mount allows lightweight, one-person installation, and the NEMA 4X, 1,000 V-rated design can go on a wall, a pole or flat on a roof. Wi-Fi/Ethernet monitoring and SunSpec Modbus are available with a Fronius Datamanager 2.0 card.
Highlights
- 15,000 VA output at 208 V three-phase
- Integrated string fuse holders (6+ / 6−)
- Integrated AFCI, DC disconnect, ground-fault protection
- SnapINverter mounting; NEMA 4X indoor/outdoor
