Check with your power company. They may be able to switch taps on the
transformer to reduce the voltage. I

Hopefully HP Voltage "Derated" the Cap as well so it can handle our

You wouldn't even need a UPS, check Google for mains voltage conditioners.
APC's kit, for example, should be available worldwide and they make a
range that, here in the UK anyway, starts for under 50 GBP.

Running load might not be quite as bad as you'd expect, switching them all
on at exactly the same time would probably cause a nice fat pulse but
perhaps that's a bit extreme:-), allowing an adequate margin though is always
a
good idea.
If you could tap into the supply and get an idea of ru
