How to calculate UPS battery load capacity?

by：Vglory 2021-03-27

The unit of UPS capacity is VA, which is the unit of apparent power. Because the UPS battery has the ability to lose during the inverter process, in general, the UPS also consumes electricity, so the output power it can supply will not be this value. The general small UPS power factor is below 0.7. In other words, only less than 70% can provide external power supply. For example, if the power factor of the 1000VA UPS is 0.6, it can only output 600W (active power) externally, and the 400W is consumed by itself. This part is called reactive power! UPS battery capacity generally refers to the capacity of the back-end load. Taking a 10KVA power UPS as an example, the output power factor is 0.9, and the full load power of the UPS is 9KW. If the back-end load is 6KW, the UPS usage efficiency is 6/9u003d66.7%. Battery capacity: Ampere hour per battery AHu003dload Total power W*time (hour) H/12V/battery series connection number. For example: 80K load capacity requires 2 hours of standby, 32 batteries, each 12V, 80000*2/12/32u003d416*1.2u003d500, 5 sets of 100AH u200bu200bbatteries are just fine, such as: 3K load capacity, To stand by for 1 hour, 8 batteries, each 12V, 3000*1/12/8u003d31, just use 1 set of 24 or 38AH batteries.
