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.
• The new 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 is field programmable to 208, 240 or 277 volts, eliminating the need to install different inverter models to accommodate three-phase installations.
