How Big Should My Uninterruptible Power Supply Be?
A UPS is most efficient when the capacity closely matches the overall load without falling below the necessary levels.
In other words, youll want to avoid using a UPS with a lower capacity than the intended load.

Larger batteries or external battery packs (if the UPS supports them) will increase runtime.
On the other hand, more devices and more power draw decrease runtime.
Figure out all of the electronic devices youll be connecting to the UPS.

Determine both the voltage and the amperage for each rig.
It should be included in the devices documentation or listed on its nameplate.
The VA total would then become 224.25 (195 x 1.15), accounting for 15% growth.

Find the capacity of the UPS battery in ampere hours (Ah).
Find the input voltage of the UPS.
Multiply the battery capacity by the input voltage, then divide that number by the total load.
