hi,
i have a sukam 1500va pure sinewave inverter and it makes an annoying sound continuously.i had called the sukam CC and after checking he said all sinewave inverters make this sound.
previously i had a nonsinwave sukam inverter which ran silently.Do all sinewave inverters make this annoying buzz/screech?
thanks
 
They do when they are providing backup or when the battery is charging.. Once its on mains then the noise is quite low almost inaudible...
