Transformerless ISGA series inverters from Carlo Gavazzi are available in 4 sizes with AC rated outputs ranging from 2.2kW up to 5.5kW. The use of advanced technology DSP control enables accurate and fast operation of the MPP tracking circuit which turns into high yield. The intuitive mimic display allows easy setup of the unit and provides to the user many useful information of the main production parameters: String by string voltage, current and power, output voltage, current and power, energy yield, inner and heatsink temperature, error and status messages. The 3 LEDs on the side of the display provide information about the unit status at a glance. The ISGA inverters have a protection degree IP 65 / NEMA 3R and are thus suitable for indoor as well as outdoor installation, furthermore they are very quiet, as they not utilize a cooling fan. Long lifetime is ensured by high rating components and a thermal management design aimed to reduce components thermal stress. ISGA inverters are particularly robust when it comes to grid faults, guaranteeing uninterrupted energy production even on highly disturbed utility grids.
