A UPS system is intended to do the following:
- Protect the connected inverter load against power failures of all types, whether short or extended
- Protect the connected inverter load against surges in the supply grid
- Ensure inverter load is kept running all the time and prevent the user from losing money.
Although the UPS and its functions are clear, there are other factors that should be taken into consideration when buying a UPS:
- Quality of build
Poor quality builds will use cheap capacitors and fans that will require more frequent replacement leading to a higher long-term cost of ownership than higher quality brands such as Riello using high-end components. - UPS brand reputation in the market

- Local support structure, spares holding and in-house repairs by the supplier like Standby Systems have to offer.
