The Fronius IG Plus and IG Plus V generation of inverters represents an evolution of the proven Fronius IG product family. The IG Plus will be replaced by the IG Plus V when stock is depleted. The main enhancement on the IG Plus V is the addition of an external DC Disconnect, where as the IG Plus has an internal DC Disconnect. Available from 3 to 12 kW in a single inverter, this family promises suitability for residential and commercial applications. With a maximum effiency of 96.2%, the Froius IG Plus and IG Plus V line achieves one of the highest values for transformer inverters. The Fronius IG Plus and IG Plus V utilize our unique MIX tm technology on all inverters with two or more power stages (5.0 to 12kW). This means maximum power harvent out of partial loads ie. morning, evening and cloudy days. Automatic HF transformer switching function produces a constant high level of efficiency across th entire input voltage range. Lastly, Fronius is introducing the Fronius Service Program or FSP. Froniu will factory train professional PV installers to service inverters in the field.
