Carlo Gavazzi ISGA Series of grid-tied PV invertersCarlo Gavazzi's ISGA Series of grid-tied photovoltaic (PV) inverters feature a transformerless design, which does not incorporate or require a cooling fan.

The ISGA Series are available in 2-kW, 3-kW, 4-kW and 5-kW output sizes with a 240-Vac, 60-Hz single phase output and 6 kW to 15 kW, 120/208 Vac Wye or 240 Vac Delta, 3-phase 60 Hz output. The inverter has an output efficiency up to 96.4%, with CEC ratings up to 95.5%. The ISGA Series inverter has an input voltage range of 150 Vdc to 450 Vdc, allowing customers to realize an increase in ac production time. Some models also offer the ability to connect two individual MPP inputs. The input is protected from overvoltage, ground faults, reverse polarity, and surges.

The ISGA Series inverters feature a user-friendly LCD display and are easily installed via a quick-mount bracket. The built-in combination ac/dc disconnect switch also allows for quick installation without the need for a separate externally mounted disconnect switch. They have an environmentally robust and durable powder coated metal housing, with a NEMA3R outdoor rating, and can operate from -4 F to 122 F (-25 C to 50 C). The inverters also come standard with an RS232 output. RS485, Ethernet, USB and Web Server capabilities are available as options.

The ISGA Series are CE marked and ETL approved to meet these standards: UL1741, IEE1547/IEE1547.1, CAN/CSA STD C22.2 No 107.1, FCC Part 15, Class A and B.
