If it's DC equipment you are trying to protect then these already have rectifiers in their power supplies, which provide some basic smoothing.
You'd need 2.4KW thru your 12V DC to get 2KW after stepping up and inverting. That's 200A. So a "little capacitor" wouldn't last long.
For a weird set of reasons, taking it up with the electric company simply doesn't work.

Information might be available from the manufacturers or from knowledgeable repairman (if you can find them near you or on the net). There are forums where engineers talk casually about their problems where you might ask about the actual damage certain equipment is likely to encounter.

Going offgrid is fine, except the batteries in my UPS wouldn't last that long (as the fluctuation usually happens all the way from 7am to 8pm ). Maybe running on an inverter-style generator would be a handy solution?

Please do understand that you can get things off the shelf that offer diferent solutions to diferent problems. But diferent things will be present on diferent shelfs around the world. Maybe your problem can be solved with a simple voltage regulator, maybe not. Maybe you can solve it using a managed UPS and configuring it properly. But it could be in such way that your input is so dirty/unstable that you have to resort to turn it to DC and back to clean sine AC...
There are also other considerations on energy efficiency, because energy transformations have an energetic price, so there is loss at every step of the way, this can make your electricity bills increase.
DIY at this level is cool for people who know what they are doing. VERY EXPENSIVE errors can occour... even to people that know what they are doing.
But consider your budget and options. You may even get to realize that since you are investing you can go offgrid with just a bit more.
