I recently purchased a cheap 1kw grid-tie inverter to feed power from solar panels into the grid, the problem is it causes toaster to buzz, TV to hum, induction heater will not work. This , I guess is because the output is not pure sine wave.

What can be done? Will a power line filter help?... Thanks.

A filter may help, but the problem imho is a bad inverter design. Connecting this inverter to the mains grid may get you into trouble with local regulations and your utility/supplier because you will introduce distortions into the grid.
You're probably on the safe side running this inverter offline only.
