Important features

Flexible system design – SuperFlex Design

• Two MPP trackers and wide DC input range: Easily handles different roof orientations, shaded areas or different modules, enabling simpler and more economical system design.
• High system voltage: All inputs can handle the full rated power of the inverter, providing maximum freedom in design.

Easy installation and maintenance – SnapINverter technology

• Two separate units: The connection area and the circuit module can be installed separately, so only the circuit part needs to be removed for maintenance.
• Innovative wall mount: The inverter simply snaps into place and is secured, making installation and servicing easier.

Integrated data communication

• Built-in data logging and network connectivity: Connects to the internet via WLAN or Ethernet without additional cabling, allowing you to continuously monitor system performance.
• Open interfaces: Integration with other systems is possible with support for Modbus TCP and RTU SunSpec and the Fronius Solar API (JSON).

Optimized energy production – Dynamic Peak Manager

• Intelligent MPP tracking: The algorithm regularly analyzes the energy distribution and always provides the best performance, even in partial shading.

Future-proof technology – Smart Grid Ready

• Advanced network functions: Dynamic power control and reactive power regulation ensure stable network operation in the smart grids of the future.
• Zero feed-in: The inverter is able to completely disable energy feed-back to the grid, thus meeting the regulatory requirements of different countries.

Active cooling system

• Longer lifespan: Active cooling ensures a consistent temperature in the inverter, which prevents overheating and extends the lifespan of the device.
• Increase energy efficiency: Optimal cooling results in better performance and lower maintenance costs.

Environmentally friendly operation

• IP65 protection: The inverter is dust and water resistant, so it works reliably both outdoors and indoors.
• Low nighttime consumption: <1 W power consumption during inactive periods, contributing to energy efficiency.
