Carlo Gavazzi Introduces ISGA Series Of PV Inverters

Carlo Gavazzi has launched the ISGA Series, a new range of grid-tied PV inverters. The ISGA Series features a transformerless design that does not incorporate a cooling fan. Cooling fans have moving components that can fail, which means their exclusion in the design leads to a longer, maintenance-free product life span, according to Carlo Gavazzi. The inverters feature a warranty of up to 10 years.

The ISGA Series inverters are available in 2.2 kW, 3.3 kW, 4.2 kW and 5.3 kW output sizes, with a 240 VAC, 60 Hz output. The units have an output efficiency of up to 96.4%, with CEC ratings of up to 95.5%, the company says. The inverters can accept 150 VDC to 450 VDC inputs and up to two strings or two maximum power point trackers.

The ISGA inverters feature an LCD display and are easily installed via a quick-mount bracket, the company adds. They have a powder-coated metal housing, with a NEMA3R outdoor rating, and can operate from -4 degrees F to 122 degrees F.
