    I read in one of the articles I've been researching that these too are stressed by the square wave shaped power of these UPSs. I'll try to find again where.

    That is where https://digilander.libero.it/hibone/...est_Report.pdf comes in.

    The ability to handle 105C does not make it able to handle an over-voltage; but I agree with the Guru, things will probably be OK on a rectangular wave UPS, but if you prefer sine-wave that is understandable.

    I much prefer your attitude to someone that is just "whatever"...
