The Fronius IG Personal Display is easy to install and easy to use. The readout and inter-face are based on the same display that comes standard on all Fronius IG Series inverters. Although tested to 150 feet indoors and 500 feet outdoors, there are many reports from the field of the units transmitting from much farther distances. The Personal Display can aggregate data for up to 15 Fronius IG inverters or show data for each individual inverter in a system – i.e., data from a system that is over 75 kW AC can be viewed together or as sub-systems. It shows instantaneous data such as power, voltage and current, and it will store the daily and cumulative data. The display offers two levels of access: easy and pro. In the easy level, homeowners can view system basics like power, energy output, CO2 offset, and the number of dollars saved. The pro level offers more advanced information like voltage, current and grid frequency. The unit was designed with a backlit display and a stylish silver case to attract the attention of solar enthusiasts and their visitors alike. The display can mount on a wall near a thermostat or clock, or be placed on a coffee table or night stand. A wireless card is required for each inverter to be monitored.
