Fronius Symo 3.0-3-M Light Three-Phase Inverter
Modelo: Symo 3.0-3-M Light- Sku: FRONINV037
- Vendor: Fronius
Specifications
Product Description
The Fronius Symo 3.0-3-M Light Three-Phase Inverter is the most competitive option to start three-phase self-consumption projects with professional quality. It maintains the electrical platform of the Symo 3 kW (two MPPT, wide voltage range, and advanced MPP tracking) in a compact format with IP65 protection and SnapINverter technology for quick installation and maintenance. By dispensing with WLAN/Ethernet and the integrated web server, it allows budget optimization when monitoring is centralized in an external meter or EMS without sacrificing safety or performance.
Main Features
- Nominal power: 3 kW three-phase with European efficiency ~96.5% (η max. 98%).
- 2 independent MPPT with 3 terminals per polarity and wide DC range (150–1000 V).
- SuperFlex design: supports different orientations and slopes on the same roof.
- Integrated safety: DC isolator, insulation measurement, and reverse polarity protection.
- IP65 for indoor/outdoor use, active ventilation, and SnapINverter technology for agile mounting.
- “Light” connectivity: RS-485 (Modbus RTU SunSpec) and digital I/O for EMS/SCADA/meter.
Advantages or Benefits
- Optimized total cost: same electronics and production as the WLAN version, with less communication hardware.
- Maximum flexibility on complex roofs thanks to its 2 MPPT and intelligent MPP tracking.
- Reduced installation time: accessible terminals, low weight, and wall mount with SnapINverter hinge.
- Reliable outdoor operation with IP65 and active thermal management.
- Ready for grid regulations with power control and programmable cos φ.
Purpose or Applications
Three-phase residential and small commercial self-consumption; roofs with two orientations; installations with centralized monitoring via SCADA/PLC or smart meter; projects with zero feed-in and dynamic power control.
