The difference between an inverter and a UPS

 Inverters are electrical back-up appliances which will switch to using batteries when the mains supply have been cut off. The inverterts have an input that collects electric charges which will charge the batteries and at the same time supply the load. When the main source of supply have now been cut-off, it will now seize to get
power from the input; the batteries that have been connected to it will then begin to supply power through the output. The period of switching is usually about less than a second.


The batteries of inverters are placed on racks usually beside the inverters.

A UPS is quiet different from the inverter in the sense that, the load of a UPS is connected directly to the batteries, so it does not need to switch incase there is power outage from the mains. In most cases the batteries are placed inside the UPS.
