WHAT IS INVERTER? AND WHAT IS UPS?

• INVERTER
• An inverter, or a power inverter, is a power
  electronic device that converts direct current
  (DC) to alternating current (AC). It can be used
  as either a standalone device capable of
  receiving power from DC sources such as solar
  power and battery, and converting it to AC
  supply, or a utility-interactive inverter being
  one part of a bigger circuit such as power supply
  unit or UPS. An inverter does not generate or
  store power, but it can be connected to power
  sources, generally batteries, to support power
  supplies.
• UPS (UNINTERRUPTED POWER SUPPLY)
• A UPS is a hardware device that provides backup
  power source when there is a power failure of the
  primary power source or a significant power drop.
  A UPS system contains a number of components. For
  a basic UPS system, it contains batteries, a
  battery charger, an inverter and a transfer
  switch. In this basic UPS system, the inverter is
  used as the device to convert the DC to AC since
  the power from battery use DC current but it has
  to be distributed in the form of AC. More
  information about UPS is available in What Is
  Uninterruptible Power Supply or UPS.

UPS VS INVERTER DIFFERENCES
UPS INVERTER
MAIN FUNCTION Providing backup power supply for devices to work on smoothly Converting DC to AC and storing power in the battery
ENERGY STORAGE Yes, includes built-in batteries and a charge controller No, but many inverter modules can use external storage
BACKUP TIME Power back up for short duration Power back up for long duration
CHANGEOVER TIME Around 10 milliseconds Around 500 milliseconds
CONNECTION Connected to appliances requiring alternative power Connected to batteries and appliances
POWER INPUT Around 240-279 Vac Around 170-270 Vac
BATTERY MAINTENANCE No maintenance required Requiring continuous maintenance
CIRCUITRY SOPHISTICATION More sophisticated Less sophisticated
PROTECTION Providing protection to load No protection against line abnormalities provided
APPLICATION For electronics application domestic or industrial use For general electric application

SHOULD I CHOOSE A UPS OR AN INVERTER?

• Since both UPS and inverter have their merits,
  how to choose between them? Maybe you have got
  your answers after checking the comparison chart
  of UPS vs. inverter difference above. There are
  factors such as costs, power requirements and
  protection, etc. for the product to be
  considered. To make it simpler, it all comes down
  to your backup requirements and the most
  important thing to be considered is the extended
  delays in the power supply.

WHICH SHOULD I CHOOSE FOR MY HOME/BUSINESS UPS
OR INVERTER?

• If you have not deployed either of them, this
  section is for you. For large business and
  organization applications that have high
  requirements in the respective of power system
  reliability, there is no doubt to choose the
  device with minimal delayUPS to ensure data
  security and profits. For home use, if you are
  wondering if an inverter can be used as UPS in
  order to save costs, the answer could be It all
  depends. If using inverters for general domestic
  electric gadgets whose working doesnt get
  affected by the long switching time, it is
  feasible. For example, for most home electric
  gadgets such as bulbs and TV, the delay is
  endurable. However, for those critical devices
  like computers, it is advised to use UPS instead
  in case of data loss.

DO I NEED A UPS IF I ALREADY HAVE AN INVERTER
FOR MY HOME?

• Some may get worried about whether the inverter
  can cope with the power outage of the PC properly
  and intend to add a UPS. If you do not want to
  use PC on the main inverter but want to connect
  to a UPS, it is OK. But note that sometimes UPS
  units dont work well with an inverter (like a
  traditional UPS and an outdated square/triangle
  wave output inverter), the sine waves are
  terrible consequences may occur. But if the
  inverter combined with UPS is a pure sine wave
  inverter and the UPS can handle the sine wave, it
  is reasonably practicable.
• For a better experience, you are recommended to
  call the inverter vendor and search for help from
  Power Guard Electronics technician.
