Fronius IG Plus A 11.4-1 UNI Summary

Fronius 4,210,127,800 IG Plus Advanced 11.4-1 UNI 11,400 Watt Inverter

4,210,127,800 IG Plus Advanced 11.4-1 UNI 11,400 Watt Inverter

An outstanding addition to the family: The next generation of filed serviceable Fronius IG Plus Advanced inverters include industry first Arc Fault Protections in a High Frequency inverter, Advanced grid Features for Smart Grid Integration, built in Com Card for data communications, and DC connecting distributors included with all three power stage inverters.  Add these to our impressive list of standard features including a built-in six circuit string combiner, integrated lockable DC Disconnect, multiple power stage Mix Technology with "Power on Demand" and built in redundancy, lightest and best looking in class satin finished aluminum NEMA 3R housing with Power Plug system for easy installation.

Features of the Fronius 4,210,127,800 IG Plus Advanced 11.4-1 UNI 11,400 Watt Inverter

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.
