Ordinary euro sockets are desirable, but not critical.
Software for PC.
It is desirable to be able to replace the batteries yourself.
Not odorous.
Budget 20-30k + -.

While looking, I saw:
CyberPower CP1500EPFCLCD - it fits in all respects, but there are a lot of complaints about the quality in the reviews, plus one battery is upside down

EATON 9E 1000i - noisy
PowerCom Macan MAC-1000 - noisy

If anyone has experience with good UPSs - please recommend models.
