Uninterruptible Power Supply – 7 points for smart and cost-effective UPS selection
Normally, when buying a sober item like an uninterruptible power supply (UPS), we look for the lowest price for the simplest device that meets all the requirements. However, those who shop around and consider sensible and cost-effective solutions before purchasing a UPS will be generously rewarded.
UPS systems protect computers when power is available and continue to provide conditioned battery power during a power outage. Depending on your specific application, you may need to determine basic requirements, such as the type of UPS, it’s capacity (size) in units of VA (volt-amperes) or kVA (kiloVA), and battery backup time.
Once you know the basic requirements. Then you can shop around to find the best price for a suitable UPS (uninterruptible power supply). But you can do more than that. By looking around the market, checking what products are available and at what prices, and considering the creative recommendations suggested, you can save a lot of money and still reap the additional performance benefits.

Here are seven points to consider in order to make a wise and cost-effective decision when purchasing a UPS:
- as a rule of thumb, you should choose the Line Interactive type over the Standby type and the On Line type over the Line Interactive type for better protection. Therefore, if no other considerations prevail, you should choose the best system if it is only slightly more expensive.
- compare the quoted price of the UPS with the price of the next larger system. Consider buying a larger unit if the additional price is not significant. A larger UPS (uninterruptible power supply) will allow you to increase your future load. And have a larger battery with longer backup time, and extend battery life.
- Consider purchasing a larger system if you need to increase battery capacity beyond the standard battery that comes with the UPS. You can pay significantly less for a larger UPS (uninterruptible power supply). That already comes with the battery size you need then for a smaller system with a larger battery.
- Check the impact of splitting the load or buying systems that can run in parallel. In some cases, the cost of two systems, each with half the total capacity, may be less than the cost of a single UPS system.
- Consider using multiple independent single-phase UPS systems instead of a three-phase UPS if the load and installation permit. Generally, the cost of two or three single-phase units is less than a three-phase system. In some cases, multiple systems can increase power reliability through redundancy.
- Consider the cost of using three single-phase UPS systems. Each is powered by different phases, instead of one three-phase UPS system if the load and installation permit. This configuration allows the partial operation to continue in the event of a single UPS (uninterruptible power supply) or input phase failure.
- In a redundant configuration, two or more units operate in parallel, with at least one unit serving as a backup. In this way, the power supply is fully maintained even if one UPS fails. Review the possible combinations to determine the lowest cost. For example, for a redundant system with a load of 20 kVA. Compare the cost of two parallel systems of 20 kVA and one of three parallel systems of 10 kVA each. (A common mistake is to assume that the latter solution is always cheaper because of the lower total capacity.)
How much benefit can you get from this?
Here are some examples:
Based on the average price of low-capacity UPS systems. The price of an online UPS is almost twice that of Line Interactive. This ratio decreases as capacity increases. If you want to buy an online system with 5 kVA, you probably only need to add 10%.
To increase the capacity of an online UPS from 1 kVA to 1.5 kVA, or from a three-phase 20 kVA UPS to 30 kVA, you probably only need to add 20%.
Three single-phase UPS units of 5 kVA per phase can cost about 30% less than a single three-phase UPS of 15 kVA.
Three 30kVA units in a parallel redundant configuration for a 60kVA load can save up to 25% (compared to two 60kVA units).
Performing the suggested cost-effective items before purchasing an uninterruptible power supply can result in a better solution at a much lower cost. Before making a final decision, check the availability and price of the particular system on site. As well as additional technical constraints on the use of the suggested solutions.
