The Fronius Primo 11.4-1 is a transformerless single-phase SnapINverter for residential grid-tied solar on 208 or 240 V service. Its hinged SnapINverter mount lets one installer hang the wiring compartment first and drop the power stage in afterward, and the two MPP trackers plus a wide input window make layouts with multiple roof faces straightforward. Integrated Wi-Fi and Ethernet connect the inverter to Fronius Solar.web monitoring, and SunSpec Modbus and zero feed-in control simplify utility and energy-management requirements.
Highlights
- SnapINverter mounting for fast, one-person installation and easy service
- Dual MPPT with SuperFlex Design for flexible string sizing
- Integrated AFCI, DC disconnect and ground-fault protection; NEMA 4X enclosure
- Built-in Wi-Fi / Ethernet, Fronius Solar.web, SunSpec Modbus TCP/RTU
