SnapINverter technology

The Fronius SnapINverter generation features a simple, standardized hinged mounting system that makes installation and service easier than ever. The inverters consist of two main parts: the power stage and the connection compartment, ensuring a convenient installation process. First, you mount the remarkably lightweight connection compartment and all wiring to the wall. Then simply snap the power stage in - allowing for installation within 15 minutes by only 1 person! Furthermore, installers don’t need to remove the entire inverter for servicing. Just take the power stage and leave all wires in place, making the Fronius SnapINverters the most user-friendly inverters on the market.


Integrated data communication

Fronius believes that every solar system should be monitored. Therefore, we offer integrated data communication capabilities for all our inverters and free online monitoring with Fronius Solar.web. Simply connect the inverter to the internet via Wi-Fi and use our Modbus TCP SunSpec, Modbus RTU SunSpec or Fronius Solar API (JSON) interface for seamless data communication to third parties. The different interfaces can be operated in parallel to the Fronius Solar.web online platform. The monitoring is easily set up via our smartphone app - it's so easy, even the home owner can do it.


Design Flexibility

Fronius inverters offer great design flexibility, giving you all the options you need and making system design extremely simple. Two independent MPP trackers, wide DC input voltage windows and oversizing of up to 150% make the inverters suitable for complex roofs, different array sizes and multiple orientations. The Fronius Design Flexibility offers a solution for all your system design needs


Smart Grid Ready

Fronius inverters enable the grid of tomorrow. Our inverters are already equipped to meet the technical requirements of a smart grid of the future. A set of smart functions, known as Advanced Grid Features, are built into the inverters. They include a wide range of control functions for dynamic feed-in of both effective and reactive power. These functions are designed to enable a stable grid and highest solar density, while preventing unwanted system shutdowns if grid parameters exceed their thresholds.


Arc Fault Circuit Interruption Integrated

The Fronius Arc Fault Circuit Interruption (AFCI) makes each inverter NEC 2011 compliant and offers a best-in-class solution for detecting arcs. Ensuring the utmost safety, AFCI shuts down the inverter in the event of an arc fault within your solar system.


Active Cooling

Active cooling technology relies on one or more fans, which not only avoid hot spots, but also regulate the air circulation inside the inverter, thus keeping the temperature of the power electronics low. This has a positive effect on the service life of the devices, optimises yields and reduces costs. At Fronius, active cooling is supplied as standard in all devices.
