1) At rated grid voltage (V ac,r ), Cos(phi)=1.
2) To utilise the full range, asymmetrical layouts must be considered
including start-up voltage for at least 1 string. Achieving nominal
power will depend on configuration.
3) At symmetric input configuration.
4) SPL (Sound Pressure Level) at 1 m under normal operating
conditions. Measured at 25 °C.
