Selection of an appropriate capacity UPS, measured in Ah or battery capacity, and VA or UPS capacity, is critical to guarantee powers are well protected. To begin with, you are required to calculate the aggregate capacity of all devices you wish to protect with the UPS, measured in watts. This value should be subtracted to get the capacity in VA, considering a power factor measure of 0.8 common among most appliances. The UPS should have a higher capacity than what you need.
Where battery size is concerned, the higher the Ah value, the longer the backup time will be. Even a few minutes of backup time may be achievable with smaller batteries, which will depend on the Ah value, but for a longer backup time during frequent outages, one will need to go for batteries with a higher Ah value or additional battery packs. Efficiency losses must be considered for battery size calculation.
