UPS is the equipment for providing an uninterrupted power
supply to the load but inverter is for converting the DC
supply to AC supply at a constant voltage irrespective of
input voltage.Generally UPS is connectine in parallei to
the load or the load may be through UPS to avoid cutting
off the supply when an interruption in the source of
power.Generally UPS is a system having a battery and an
inverter. Battery will feed DC power to the inverter and it
convert the DC into a constant AC out put.
