What is the difference between generator and ups

If there is an automatic restore, then it may take as many seconds to restore power. Inverter draws power from a battery that is already expected to have power, and should be periodically recharged or on at all times. An inverter is easily placed at or inside a small office.

There are also low capacity inverters, as well as large capacity inverters. If the power supply lasts for a very short period of time, it will be useful for the inverter for a few hours, in particular.

The generator can be started when power supply interruption is to be prolonged. When there is no power supply in an environment at all, if the power in the battery is drained the inverter would be of no use. Inverter should only be used for a few hours, because otherwise it would drain the battery.

It requires maintenance of the batteries. Most electronic devices such as computers may be reset even though they are on an inverter, because there is a small interruption in the power supply. Current from outside is sent directly via an inverter to your computer. The battery is not getting involved. However, there is a system which will test if there is power supply. Once no power supply is detected, a change occurs immediately and there is battery supply.

However, the short time of 1 or 2 seconds for detection and turn-over creates problems for many sophisticated computer tools. At UPS, the supply always comes from the battery. Here the key supply is used only for battery charging.

And, when the battery is depleted the UPS just stops running. The UPS is more expensive than the inverter, because of the more complicated circuitry involved. Progress in engineering has led to products containing a mixture of the above 3 in them. Can supply power to the computer and electronic systems. Power sources are Water turbines, Wind turbines, etc…. Create lots of noise. The main function is to convert mechanical energy into electricity.

Needs a Chord to start the generator. Switch and sensor are provided, which turns on inverter after the main supply is OFF. Automatically turns ON when an interruption is detected in the main power supply. Can generate electricity as long as the power source is applied. The amount of power supplied by inverter depends on the amount of charge present in the battery. Does not turns ON until the chord is pulled. Amount of electricity generated can power up 10 to 12 homes.

Can supply power to some selected appliances of the home only for 4 to 6 hours. Can supply power to electronic systems like computer, only for 10 to 15 minutes. Though designed with the same aim to substitute electricity, generators, inverters, and UPS Uninterrupted Power Supply differ in their working principle, type of application and power sources. UPS have complex wiring and are expensive. Whereas generators and inverters are less expensive.

UPS contains built-in batteries whereas for inverters batteries are external. Inverter can be used only for a few hours as otherwise the battery will be drained out. Battery maintanence is required. Some electronic goods like computer will get reset even if on an inverter, because there is a small disruption in power supply.

Use of UPS:. In an inverter, current from outside is directly supplied to your gadget. The battery is not involved. However, there is a mechanism that will check if power supply is present. Once it is detected that the power supply is not present, then immediately a change over happens and supply takes place from battery. However, the small time of 1 or 2 seconds for the detection and change over causes problems for many sophisticated electronic gadgets.

In the UPS, the supply is always from the battery. So for the gadget, it really does not matter if the main supply is present or not. The main supply is used here only to charge the battery. So only when the battery is drained does the UPS stop working. One more advantage is UPS has protection from voltage fluctuations as the supply is from battery while for inverter the output voltage is based on input voltage.
