The Ultimate Guide to Buying the Right UPS

The Ultimate Guide to Buying the Right UPS There is no denying that Uninterruptible Power Supply or UPS has become more and more critical for the maintenance of power to essential systems and operations. They count on dedicated batteries to protect critical loads from utility-caused power problems including spikes, brownouts, fluctuations, and power outages. This critical and strategic importance of UPS means that no business whether small or large can work efficiently without the installation of UPS systems. This blog will give you straightforward information about UPS so that you can make an informed decision

Why Do You Need UPS System?

UPS systems perform the following functions:

  • They are instrumental in avoiding damage to hardware that may result from either overcurrent or voltage spikes. Some UPS models ensure power stabilization and regulation as well.
  • UPS protects against data loss and damage. Without a UPS system, the sudden shutdown can lead to corruption or complete loss of data. In case you have installed power management software, UPS can help you perform the controlled and orderly shutdown of the systems.
  • They make sure that businesses continue accessing the network and running other applications during power problems while avoiding downtime. If you are using UPS in conjunction with generators, you will have enough backup power to keep running the systems and operations till the resumption of utility power.
  • These are mission-critical functions that are essential for ensuring the productivity and continuous working of organizations in the event of failure. This self-evident importance of UPS systems means that their selections should be made after thorough deliberation.

Buying the Right UPS: Key Considerations:

Here are qualities of the UPS system that you should give serious consideration:


You should determine and calculate the amount of power required to run equipment during a power outage. The equipment load, runtime, power factor correction, and anticipated future needs should be considered for determining the required VA or Wattage rating for your UPS.

Though the recommended capacity of UPS depends upon your specific needs and requirement, as a general rule, a UPS with a capacity of 500VA-1500 VA would be enough for small- and medium-sized businesses and home offices. On the other hand, you may need a UPS with 5000 VA or more capacity to provide power protection and regulation to large businesses, data centers, and mission-critical applications.


Runtime is the amount of time that your equipment and operations need to run continuously during a power outage. The total power consumption of equipment, the capacity of the UPS battery, and the efficiency of UPS systems are key determinants of runtime.

For a small-sized business and home office with a PC or a few peripherals, a runtime time of a few minutes would be sufficient to save data and safely shut down devices. Under these circumstances, a UPS with a runtime of 15-20 minutes would be enough. And for big businesses, data centers and mission-critical facilities, you may need several hours of runtime to ensure an uninterrupted power supply during a power outage.

Power Factor Correction:

Power Factor Correction(PFC) is also an important consideration. It is the ratio of real power to apparent power in the electrical system. Since there could be equipment in your electrical system that requires more power for start than use, the real power may exceed the calculated power determined by adding a total load of equipment. Therefore, it is important to purchase a UPS system with higher power factor correction as it will help you bring efficiency to your electrical system by reducing the amount of current required to start equipment and improving the overall power consumption.

Anticipated Future Needs:

Always consider the anticipated power protection and regulation needs of your businesses. Make sure that your power protection system is adequate as your equipment requirements and operations grow over time. In addition, the growth in equipment requirements leads to an increase in the runtime of your UPS. Therefore, it is recommended to purchase a UPS system with a slightly higher capacity than your current needs.


Redundancy refers to the ability of UPS units to provide power to the connected equipment even if one or more components system fail. The redundancy can be ensured by one of the three strategies:

    Hot-Swappable Batteries

  • In this method, multiple battery modules are used in the UPS system which allows administrators to replace the failed battery without causing interruption to the power system.
  • N+1 Redundancy:

  • In this method, multiple UPS units are installed in parallel and each unit has the same capacity as the connected load. In case of failure of one unit, the remaining ones would continue to provide power uninterruptedly to the connected load.

UPS Technology:

Choose the most suitable UPS technologies to cater to the needs of power protection of equipment. There are multiple UPS technologies on the market, for instance, offline/standby UPS, Line Interactive UPS, Online UPS, Double Conversion UPS, and Ferrorosonant UPS. Each technology has unique strengths and weaknesses and should be selected after thorough deliberation.
