Fronius Symo 4.5-3-M - Three-phase on-grid transformerless inverter, 4.5 kW

Fronius Symo 4.5-3-M is a three-phase, transformerless solar inverter designed for grid-connected photovoltaic systems without a battery. It has a continuous output power of 4.5 kW, two MPPT inputs and IP65 protection rating. It belongs to the Fronius Symo family.

Main features:

  • Continuous output power: 4.5 kW (4500 VA)
  • Inverter type: On-grid, three-phase, transformerless
  • DC input: 150-1000 V, 2 MPPT
  • AC output voltage: 400/230 V, 50/60 Hz
  • Communication interfaces: Wi-Fi, Ethernet, USB, RS485, Modbus
  • Protection rating: IP65
  • Weight: 19.9 kg

With power classes between 3.0 and 20.0 kW, the transformerless Fronius Symo is a three-phase inverter designed for systems of any size. Thanks to the SuperFlex design, it is suitable for roofs with an irregular shape or different panel orientations.

The inverter has a peak power of 9.0 kW, a maximum efficiency of 97.2 %, a maximum output current of 6.5 A and a total harmonic distortion below 3 %. The maximum input current is 16.0 A / 16.0 A and the operating temperature ranges from -25 to 60 °C. Protections include reverse polarity on the panels; the product complies with the IEC 62109-1/-2, IEC 62116 and IEC 61727 standards.
