Fronius IG Plus Features…
  • Grounding selectable on site.
    Decide on site what type of grounding is required as the Fronius IG Plus is field programmable for either positive or negative module grounding.
  • Designed for indoor and outdoor installations.
    All Fronius IG Plus inverters have a robust, well designed aluminum housing.  UV resistance and corrosion protection enable them to be used either indoors or outdoors.  Fronius is proud to be one of the only inverters tested and approved to operate at 122° F.
  • Integrated DC disconnect.
    No external DC disconnect installation or cabling is necessary.  The Fronius IG Plus comes complete with an approved, built-in, lockable and load breakable DC Disconnect.
  • Power plug system. 
    The connection area and power stages are installed separately from each other. Very easy and extremely safe:  The connection area is attached to the wall as normal. Then the power module is simply plugged in.  The power plug connects both parts into one secure unit.  If service is required, the connector remains on the wall  maintaining all settings and configurations.
  • Field Programmable AC output voltage.
    The Fronius IG Plus inverter line from 3.0 to 11.4 kW is field programmable to 208, 240 or 277 volts (Fronius IG Plus 12.0 kW only availabale in 277 volts), eliminating the need to install different inverter models to accommodate three-phase installations.

The Fronius Advantage…

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.
Fronius MIX Technology
The cleverly-devised combination of several power modules means Fronius inverters always achieve maximum yield, even when in the partial-load range. This is all down to the unique Fronius Master Inverter X-Change system (MIX), a development of the classic master/slave principle. How it works: all power modules are equal. The „master“ is allocated alternately, taking into account the operating hours worked. The result is that loads are applied evenly to individual power modules and the operating time decreases.
HF Transformer Switchover
Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design, a high level of efficiency and safety as a result of the electrical isolation.
PC Board Replacement
The foundation of the unique PC board replacement 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 Partners to provide the fastest inverter servicing on the market.
WiFi Capability
Simple, user-friendly system monitoring is very important to Fronius. Made possible with a retrofitted Fronius Datamanager*, the Fronius IG Plus Advanced is capable of having a WiFi interface in the inverter itself. The inverter is then able to connect to the internet without any additional cabling and grants you the perfect overview of how the PV system is operating via Fronius Solar.web. *Fronius Datamanagers are sold seperately.
Smart Grid Ready
Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. These include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses. Fronius inverters therefore help to guarantee the yield of a PV system.
