My inverter got noisy whenever i plug a fridge in it. Any clue to reducing the noise? Thank you.

As i guess the inverter was noisy well before you plugged in the Fridge. The noise then increased when you plugged it. Naturally the compressor inside the fridge is an inductive load and the inverter is a quazi sine or an square wave one thus the niose generated. The ultimate solution to eliminate the noise is to use a Sinewave inverter.My inverter got noisy whenever i plug a fridge in it. Any clue to reducing the noise? Thank you.
The inverter is a sine wave inverter. It was almost not audible before the fridge was plugged in. It became noisy only when it runs the fridge.
Finally. Its was the buzzer that was making the noise. I removed the noise by using a 0.1uf capacitor at the input of the transistor that controls it.
The inverter now works normally. Thanks people.
......I built the inverter myself.....
