Not all UPS reform the sine wave. ALL of the low cost ones I have
played with merely pass through the line, then switch to internal
power when the line goes away.
My main worry would be over voltage. Get a voltmeter!
PS: None of those low cost UPS, that I played with, put out a sine
wave - they put out a "modified sine wave" which has a zero volts
time to allow a peak voltage the same as a sine wave, with a RMS the
same as a sine wave:
