Equipment features


On-site module grounding

Decide on site whether it is desirable or necessary to ground modules. Insert fuse and enable software - ready for grounding.

 

Indoor and outdoor use

All Fronius IG Plus devices have a rugged, elegant metal housing. They are UV-resistant and have corrosion protection, making them suitable for use both indoors and outdoors.  

 

Integrated DC disconnector

No additional installation work or cabling is necessary. Extremely convenient and highest levels of safety according to DIN-VDE 0100-712..

 

Integrated string fuses

Up to 6 strings can be directly connected to all Fronius IG Plus inverters. The integrated holders for string fuses allow the module strings to be disconnected from one another depending on the module manufacturer's requirements.

 

Technology


Fronius MIX technology

The cleverly-devised combination of several power stage sets 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 stage sets 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 stage sets 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.


Integrated WLAN interface

Simple, user-friendly system monitoring is very important to Fronius. With the Fronius Datamanager, we are the first inverter manufacturer to offer a WLAN 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.


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.
