Fronius
IG Plus Advanced Grid Tie Inverter, 3.0-1
3 kW, 208/240/277 VAC
The smallest size inverters in the Fronius IG Plus Advanced family. Available in 3.0 and 3.8 kW. Best suited for smaller solar applications, e.g. residential and smaller commercial applications.
The Fronius IG Plus Advanced is the first complete inverter lineup of the NEC 2011 compliant AFCI protected inverters in the United States. Power classes ranging from 3 to 12 kW in both single and true 3 phase applications with integrated Fronius MIX Technology and wide voltage windows are the perfect match for your system design.
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. The High Frequency (HF) transformers used in each Fronius IG Plus allow these inverters to maintain a constant level of efficiency while still being compact and lightweight.
Features
- Industry high efficiency over a wide voltage range (96.2% peak)
- Fronius MIX Technology - The cleverly-devised combination of several power modules means Fronius inverters always achieve maximum yield, even when in the partial-load range.
- High-frequency transformer switchover - The automatic transformer switchover facility produces a constant level of efficiency the entire input voltage range, resulting in higher yields.
- Designed for indoor and outdoor installations - robust, well-designed aluminum housing, UV and corrosion resistant
- Tested and approved to operate at +131°F
- MPP Tracking maximized power harvested
- Field programmable output voltage (208, 240 or 277 VAC)
- Grounding selectable on-site - positive or negative module grounding
- Integrated DC Disconnect: approved, lockable, load breakable
