Generators for powering AC in India

What’s the best and not expensive generator to power at least one AC at home in India ? Trying to buy one because electricity goes a lot here in our local town. I discussed this with a merchant at a local town here but they are quoting me over 2 lakhs INR. Not sure if they are ripping me. That’s too expensive and I can’t afford it. If anyone has personal experience with buying generators in India, please revert.
