What Is The Difference Between A Ups And A Generator?


When the original power supply is interrupted, all generators and Uninterrupted Power Supply (UPS) systems are configured to be used as a backup mechanism but there is a big difference between the two. Generators are used as a temporary source of power during power outages and can keep you in operation.


There are many different types of generators available on the market so choosing the right one for your particular company is fairly straightforward. This depends on your business form, your facility size, and how much equipment you have.


The stationary generator is the largest, and the most expensive model available. They are connected to the main power supply and are designed to handle several devices. As a consequence, the large companies that use them are these.


UPS providers include a backup power supply that keeps your systems running without interruption during an outage, and protects your providers from power surges. The only difference is that these have a few minutes of power supply because they are powered by a battery. Therefore the time that they are going to keep your systems going is very limited. It depends on which unit you are installing and the power of the battery, but even bigger systems only last for a short time. They ‘re meant to run the computer as long as you can properly turn to the generator or shut down.


Generators and UPS systems work together to secure the equipment so that you can keep the business running smoothly. We also protect the data you need in your computer system to operate a profitable company. Power spikes will overload the system, and power outages can do further damage due to incorrect shutdowns.


The cost of repairing your equipment may place a burden on your budget, but it’s priceless the data you would lose. Despite power outages and growing spikes, investment in such systems is clearly smart. The experts at Eco Power Supplies will help you pick a UPS system and generator that is ideal for your company.


A generator is a device that transforms mechanical energy into electricity. A generator typically requires fuels such as kerosene, petrol , diesel, etc. That is used as the source of mechanical energy. If it needs a lot of energy a generator is also used. Small devices don’t normally require generators. A generator is used when you choose to use several applications or devices or equipment for an extended period of time concurrently.


Generator Benefits:


You don’t need an existing power source for a generator, or a fixed power supply. It means that a generator is very useful if there is no electricity for a very long time or if you are in an environment where no power supply exists at all. A generator is very powerful and if you want to supply a whole building or equipment, etc. with current, you can buy a generator according to your requirement. Rather big generators contain very small generators.


Single device disadvantages:


When the generator works, the rest of the current or power will actually be a waste if you don’t use it to the full capacity.


A generator usually has to be started as soon as the power supply departs. It would trigger the loss of power going off between the time supply and the start of the generator.


Can’t hold a generator inside your working house. That is because generators generate a lot of smoke-related noise and pollution, which can turn out to be very smelly.




An inverter helps to re-establish power supply almost immediately after a power failure. It has the option of automatically restoring power, or manually restoring power. Manual restore can lead to blanking out of sight until restore. 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.


Inverter Benefits:


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.


Inverter disadvantage:


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.




UPS stands for delivering uninterrupted fuel.


Updated UPS:


Through delivering continuous power supply, UPS stops an electric / electronic system from being switched off.


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. And for the device, it just doesn’t matter whether the key supply is there or not. Here the key supply is used only for battery charging. And, when the battery is depleted the UPS just stops running.


Another advantage is that UPS has protection against voltage variations, because the supply is from the battery while the inverter’s output voltage depends on input voltage. 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. For example, a backup that functions as a UPS at first, and then becomes an integrated inverter or generator.
