I probably have experienced this. I had an APC UPS for the comuter and a local inverter (1KVA) for the house. The UPS never picked up current from the inverter and gave the standard backup time of 15 min's or so.

And ever since the inverter was installed (2 years ago), I have had to take the UPS for repairs twice and the third time there was so much smoke that i just chucked it out.
Running without a UPS as of now.

What's bad for your UPS is also bad for your computer; so don't run your computer on inverter. Best is to run computer through UPS that's plugged into a power socket that doesn't get current from the inverter.

I have two 600VA UPSs, connected to the mains line, that is backed up by the inverter. When the power goes, (which in Pune, is very frequently) the UPSs run off the inverter. So far I've not had any problems. The inverter is a local brand - it did not mention anything about "pure sine wave" output.
