Princeton Power Systems, a manufacturer of power conversion products and alternative energy systems, has developed a 2MW inverter for the US Department of Energy’s (DOE) SunShot Incubator programme.
Princeton designed interverer to reduce the overall cost of solar installations and balance of systems in order to help the DOE reach its goal of a US$1/W total installed cost of solar.
The system features a 13.8kV grid connection, eliminating the use of a 60Hz isolation transformer. Two DC ports were added to the inverter making it a six DC port 2MW inverter.
Darren Hammell, executive vice president of Princeton Power Systems said: “Typically a system of this size would require several different parts such as multiple inverters, separate transformers, and disconnects. What we have managed to develop is an inverter that incorporates energy storage capabilities with an integrated high-frequency transformer, merging the power and capability of six inverters into one enclosure.”
