Fronius Symo 3.7-3-M-LIGHT Inverter

The Fronius Symo 3.7-3-M-LIGHT three-phase inverter from the prestigious brand Fronius has power ranges from 3kW to 20kW. This inverter features 2 MPPTs (4 inputs) and a wide voltage range of 150V-800V. With a maximum voltage of 1000V and a maximum current of 16A, we can achieve 7.4kWp in our photovoltaic installation.

Model Variations

Within this range of inverters, we distinguish 2 designations that emphasize the functionalities they come standard with.

• Models described as "Light" do not have the WLAN communication module installed. This means that the inverter data cannot be monitored via the internet. Conversely, models without "Light" have it incorporated.
• Pay special attention to the S/M designation. Models with the letter "S" only have one MPPT, while models with the letter "M" incorporate 2 MPPTs.

Features and Benefits

With power ranges between 3.0 and 20.0 kW, the Fronius Symo transformerless is the ideal three-phase inverter for any size installation. Thanks to its SuperFlex design, the Fronius Symo is perfect for roofs with different inclinations or orientations.

The connection to the internet via integrated WLAN or Ethernet and the simple integration of components from other manufacturers make the Fronius Symo one of the most communicative inverters on the market. The counter interface also allows for dynamic power management and clear consumption visualization.

Active Cooling Technology

The active cooling technology is based on one or more fans that not only prevent heat fields but also regulate the air circulation inside the inverter, keeping the temperature of its power electronics low. This has a positive effect on the lifespan of the devices, optimizes performance and reduces costs. At Fronius, Active Cooling is a standard technological feature in all devices.

SnapINverter Design

The generation of SnapINverter inverters is characterized by its simple standardized mounting system. Installation and maintenance are easier than ever. One special feature in the design of the unit is the separation between the connection area and the power stage areas. Both areas are mounted separately.

After assembling the lightweight wall mount and the wiring of the unit, the power stage is installed. The innovative casing opening concept makes assembly and service extremely easy. The inverter is hooked onto the wall mount to secure it. Therefore, in case of service, it is not necessary to remove the entire inverter, but only the power stage. All wiring remains in place.
