Uninterruptible Power Supply question

Could one assume that all APC and CyberPower UPS's will in addition to providing battery backup, smooth the output A/C power? Reason I ask is that I'm in the process of installing a Generac whole house generator and while the specs look good, I still have some issue with the powering of some electronic gear. I'm just not sure if the Generac truly puts out pure sine wave voltage.

Pretty much ALL of the APC UPS versions are MSW, not sure about "Cyberpower" but I suspect they may also be MSW since they tend to be a lot cheaper than APC, if not they may be extremely cheaply built PSW and if that is the case I would take a APC over the Cyberpower.

You should also understand that many UPS units will not and cannot work with a generator as a input source.

UPS units are extremely sensitive to FREQUENCY of the input. Units designed for use with US 60hz grid are looking for 60hz, not 59 hz or 61 hz like a generator will supply. Very few UPS units will work with a generator as a input.

As far as running electronic equipment from a generator goes, should be perfectly fine for 99.9999999% of the equipment out there..

Not sure as to what you feel is "sensitive" electronic equipment but I have run TVs, stereos (EXPENSIVE ONES NOT THE $100 types), Satt receivers, COMPUTERS, home fridges, power tools and so on from MSW inverters..

Truth be known, very few electronic devices are "sensitive" to "dirty power" and the disclaimers are used by pretty much every generator manufacturer warning folks to not use with "sensitive" equipment is nothing more than a CYA for the manufacturer.

Your Generac WILL supply a CLEANER SINE WAVE than any MSW UPS. Non inverter generators by there nature produce sine waves, that is where the grid (shore power) gets their sine waves.

The only thing about portable and home standalone gens is they may have some waveform distortion, typically 10% or less but that IS far less distortion than a MSW inverter or MSW UPS.
