How big is a 1500 kVA UPS – check out this 300 kVA Powerware UPS on eBay …

Had an interesting meeting where we discussed UPS (uninterruptible power supply) systems and we were discussing a possible acquisition of a series of “1500 kVA” units.

(This is for an IT server room, although anything over 25kVA would, in my books, qualify as a data centre)…

So I did a bit of research and found this 300 kVA UPS on sale on eBay:

OK, so if that is a 300 kVA unit and it has a price around $33K (and looks about the size of three 42U rack cabinets) .. how monstrous would a 1500 kVA unit be ?
