Sputnik launches megawatt station
The Swiss manufacturer of solar inverters, Sputnik Engineering AG, is launching a new
central inverter in October. The device with the name SolarMax 330C-SV (SV stands for
special voltage) has a rated capacity of 330 kilowatts and works in the MPP range
between 450 and 800 volts. As many as three SolarMax 330C-SVs can be combined in
