Let me compare it to a wagon or cart. If you load up a wagon all the time that is undersized for the load that means it is always carrying too much weight. You could have problems because of too much weight. The springs are going to give out. The tires are going to give out. The axles are going to break. Parts of the cart are going to break because it is undersized for that load you are carrying. If a generator is properly sized for the load you are carrying, it will be better because it is running at half speed and it is not putting as much strain on the generator at the surge level.
I have customers that have antique central air conditioners that put a lot of strain on their generator. People are constantly trying to take something smaller and make it work for bigger. Is it the price? Is the because of money? You might spend a small amount for a generator and it still doesn’t work for you. So why not spend a little more and get the size that will handle the load it is required to handle. Whatever generator size you install, it should fit the load you are carrying and code requirements should be met.
Call a professional, factory trained installer. What size is your back up generator? Is it a whole house unit or a partial house?
