inverter: The proper meaning of inverter is a device which
converts dc into ac.
The inverter also contains a battery unit and an dc to to ac
conversion unit. when the power fails the inveter will
deliver power from switching from main source to battery
source. The switching time here is normally greater than 20 ms.
UPS: The proper meaning of this is a device, which delivers
power, even if the source power fails(Uninterrupted power
supply).
This is also contains the same thing as a inverter except
here the switching time from main source to backup source is
less than 10ms, so that the computer hard drives or an
sensitive power products should not be affected from this.
Depending on the switching time there is a online ups and
offline ups. off line ups is same as a inverter.
