) CHANGE OVER TIME: An off-line ups (the standard) switches
to the batteries in 3 to 8 milliseconds, after the main
power has been lost.
The typical Inverter changes over in about 500 milliseconds

2) SIZE: Off-line UPS's go up to about 2kVA
Inverters go to 16kVA, 3 phase(what i could find browsing)

3)VOLTAGE REGULATION: UPS's have automatic voltage
regulation (AVR) set on average at 220v
Inverters output voltage is the same as the mains input
voltage (South Africa = 230V)



An inverter can transform a voltage from say 12volts dc and
up to 230v AC.

UPS means Uninteruptable Power Supply. If you use an UPS
between your computer, and your socket in the wall, and
experience a power failure, the UPS will act as a battery
and give you some extra minutes work time to save your
work, and turn of the machine properly. Without the UPS
your machine would die immediately


Electrical engineering, sometimes referred to as electrical
and electronic engineering, is a field of engineering that
deals with the study and application of electricity,
electronics and electromagnetism. The field first became an
identifiable occupation in the late nineteenth century
after commercialization of the electric telegraph and
electrical power supply. It now covers a range of subtopics
including power, electronics, control systems, signal
processing and telecommunications.

Electrical engineering may or may not include electronic
engineering. Where a distinction is made, usually outside
of the United States, electrical engineering is considered
to deal with the problems associated with large-scale
electrical systems such as power transmission and motor
control, whereas electronic engineering deals with the
study of small-scale electronic systems including computers
and integrated circuits.Alternatively, electrical engineers
are usually concerned with using electricity to transmit
energy, while electronic engineers are concerned with using
electricity to transmit information.
