Arc Fault Circuit Interruption Integrated
The Fronius Arc Fault Circuit Interruption (AFCI) is the best of its kind in the industry. The technology makes each inverter NEC 2011 compliant and maintains some of the most civilized, integrated technology available today. Ensuring the utmost safety, AFCI shuts down the inverter in the event of an arc fault.
Flexible Design
Two MPP trackers combined with a high system voltage and wide input voltage range guarantee maximum flexibility. Every DC input, and therefore every MPP tracker, is able to accommodate the entire nominal output of the inverter. The result: an inverter for every application. Thanks to a new MPP tracking algorithm, a single inverter can cope with any challenge – including different roof orientations, shading of one or two strings, or the use of residual modules.
Free Integrated Wi-Fi
Simple, user-friendly system monitoring is very important to Fronius. With the Fronius Datamanager 2.0, we are the first inverter manufacturer to offer a Wi-Fi interface in the inverter itself. The inverter is connected to the internet without additional cabling and grants you the perfect overview of how the PV system is operating.
SnapINverter Hinge Mounting System
The special feature in the design of our devices is that the connection compartment is separate from the power stage set compartment. They are installed separately. The connection area and all its cabling is fitted to the wall first. The power stage set compartment is fitted afterwards. The innovative SnapINverter mounting system makes installation and servicing extremely user-friendly. The inverter is simply placed in the wall bracket and then secured. It is not necessary to remove the entire inverter for servicing, just the power stage set compartment. All the cabling, settings and configurations remain in place.
Field Serviceable for Lowest Cost of Ownership
The foundation of the unique PC board replacement process is laid as we develop our inverters, as PC boards can only be replaced if the device has been designed accordingly. This enables our Fronius Service Providers to provide the fastest inverter servicing on the market.
