New FRONIUS IG 4000, IG 5100 & IG 4500-LV Inverters Receive UL Listing

One of the most compelling features of the new series is the Fronius MIX concept, which enables the inverters to yield increased efficiency in the part-load range while simultaneously increasing reliability and system longevity. By sharing power across two different power stages, the new FRONIUS IG inverters offer even greater redundancy than a multiple-inverter installation with all of the ease of installation and price advantages of individual, larger units.

The FRONIUS IG Series now includes the most extensive range of inverters for residential and light commercial power levels, ranging from 2.0 to 5.1 kW. Solar contractors will have the right building blocks to optimally design residential and commercial systems. At 26 and 42 lbs., the FRONIUS IG inverters are between one-third and half the weight of competing inverters. Built-in DC and AC disconnects often eliminate the need for external disconnects, reducing total system costs. FRONIUS IG inverters also come standard with the industry's most advanced LCD display where the installer and end-user can view and record over 20 parameters pertaining to inverter and system operation. Optional remote data communications and data logging features can easily be added via Plug-n-Play cards to transform IG inverters into a sophisticated data acquisition system and weather station.
