More Good News for Solar: Super-Efficient Inverters!
A maximum efficiency rating of 98.5 percent for photovoltaic inverters has been achieved by the Fraunhofer Institute for Solar Energy Systems ISE in a test using prototype silicon carbide-based MOSFETs manufactured by CREE, Inc., USA. These are the highest efficiency results reported for photovoltaic inverters to date…
Inverters transform direct current generated by photovoltaic systems into alternating current and feed it into the public grid. The higher the efficiency rating of the inverter, the greater is the energy yield of the entire photovoltaic system. To achieve the highest energy output over time, the efficiency rating should remain high over a wide range of power levels. During testing, the inverter with Cree SiC components also set a new performance precedent across a wide range of power output values.
