Triple efficiency peaks

The Fronius IG Plus 5.0-1 use an automatic transformer switching function that enables three equal efficiency peaks yielding a higher efficiency over a wide input voltage range.

With a 96.2% maximum efficiency, the Fronius IG Plus 5.0-1 scores the highest grade among HF devices.

MIX™ Concept

With combination of multiple power stages in each inverter you are able to get the most power out of partial source such as shade or cloudy days.

Module Manager™.

Keeping the inverter at the maximum power point  (MPP) is crucial for efficient operation and energy harvest. With quick and precise MPP tracking you are assured to get the most power from your system.

Smart Ventilation Design.

There are a lot of environmentally hazards that can cause damage to an inverter. The smart ventilation design for IG Plus 5.0-1 allow s the inverter to cool without exposing the sensitive internal circuits from damaging environment conditions, e.g. humidity.

Features and General Information

  • 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 line from 3.0 to 11.4 kW is field programmable to 208, 240 or 277 volts (Fronius IG Plus 12.0 kW only available in 277 volts), eliminating the need to install different inverter models to accommodate three-phase installations.
