IG Plus 12.0-3 WYE277

This three power stage inverter is available in 10.0, 11.4 and 12.0 kW. Best suited for large residential and commercial applications.

Decide on site what type of grounding is required as the Fronius IG Plus is field programmable for either positive or negative module grounding.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.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 Fronius IG Plus 12.0 kW is only availabale in 277 volts.

Greater power harvest for every system size: The unique automatic transformer switching function of the Fronius IG Plus makes enables not one, but three equal efficiency peaks. The result: Consistently high efficiency over a wide input voltage range. In comparison: The efficiency of inverters without transformer switching declines steadily with an increasing input voltage. Devices without a transformer only have one efficiency peak. With a 96.2 % maximum efficiency, the Fronius IG Plus series scores the highest grade among HF devices.

The Module Manager™ keeps all Fronius IG inverters at the maximum power point (MPP) with fast and exact MPP tracking, ensuring that you get the most power out or each ray of sunlight. This is especially important for amorphous modules whose MPP can be more challenging to track.
