Overview on the SMA inverters
The company was founded in 1981 to commercialize the emerging solar technologies industry. As most renewable energy forms (e.g., solar, wind, hydropower) generate direct current electricity, the inverter is an essential system component to 1) transform electricity from DC to AC for use in national electric grids 2) optimize the power coming from solar arrays by continuously finding the maximum power point (MPP) along the short circuit current/open circuit voltage (IV) curve of the arrays and 3) provide safety functions, such as isolating a solar array from the main electrical grid during maintenance or repairs. As of end-2010, the number of employees was approximately 5,500.
