SnapINverter technologyThe 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.
Automatic HF transformer switchoverFronius transformer based inverters use a high-frequency (HF) transformer. The automatic transformer switchover creates three efficiency peaks. The result: a consistently high level of efficiency across the entire input voltage range - ensuring higher yields than traditional transformers. Other advantages of HF transformer technology are the compact, lightweight design and highest safety as a result of the electrical isolation.
Integrated data communicationFronius 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.
Smart Grid ReadyFronius 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 IntegratedThe 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.
The deliberate design of the Fronius SnapINverter meets great enthusiasm of our insallers and customers.
