Fronius IG Plus V 10kW, 1 and 3 Phase Inverter

Fronius IG Plus PV Inverter - 10kW Uni/Delta (1/ 3 Phase) Inverter


The first complete solution. Reliable. Proven. Smart.

An outstanding addition to the family: The next generation Fronius IG Plus inverter builds on a successful model with multiple enhancements, including maximum power harvest, a built-in six circuit string combiner, integrated, lockable DC Disconnect, significantly improved efficiency, and unbeatable reliability. New, larger power stages expand the proven Fronius IG family from 2 to 12 kW in a single inverter.

The universal PV inverter with maximum yield.

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

Equipment 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.

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 availabale in 277 volts), eliminating the need to install different inverter models to accommodate three-phase installations.

Warranty and Disposal

FRONIUS USA limited 10-year warranty

At Fronius, we have been designing and manufacturing high quality power electronics equipment for over 60 years. And all our production facilities are ISO 9001 certified.

You will probably not encounter any service-related issues with your Fronius IG Plus Solar Inverter. However, in the unlikely event that within Ten (10) years from the original purchase you discover a problem caused by defects in either workmanship or materials, we will see that the device is either repaired or replaced. Repair or replacement depends on Fronius’s evaluation of the issue and what we decide makes the most sense according to the situation. The warranty is based on the inverter’s serial number, allowing the warranty to be transferred to another owner if the Fronius IG Plus solar inverter remains installed in the original installation location. Because the warranty is tied to the serial number, there is no paperwork to transfer the warranty to a new owner.

The Fronius IG Plus Solar Inverters are designed to withstand normal operating conditions and typical wear and tear when the Fronius IG Plus Solar Inverter is used for its original intent, in compliance with the Fronius IG Plus Installation and Operational Manual(s) supplied with the original equipment. This warranty does not cover damages by improper installation or operation, misuse, abuse, manipulation, alterations or repair attempts, accidents, fire, floods, acts of God, and incidental or consequential damage caused by defects with other components of the solar system. This warranty does not extend beyond the original cost of the Fronius IG Plus Solar Inverter.
