How does KELONG UPS power calculate the number of KELONG batteries when they are equipped with batteries?

How to calculate how you calculate the number of KELONG UPS configuration batteries - UPS - UninterruptiblePowerSystem is the abbreviation of uninterrupted power. The function is to provide 0 discontinuous, stable and pure AC power supply, and the UPS power supply can provide reliable AC power supply in time when the city power is not available. The length of the KELONG Ups power supply is determined by the capacity of the battery. The calculation method of KELONG UPS battery configuration is introduced as follows:
1. first we want to determine how many loads you need to supply the ups.
2. load settled choice UPS power supply, the power factor of KELONG UPS power supply is generally 0.8.
For example, a 8 kW load and a backup time of 2 hours. The calculation method is the power of the load / power factor =ups power supply, 8000/0.8=10000, and the 10 kilowatt UPS power supply is selected.
The 10 kilowatt UPS power supply is 192V, and UPS power is 10 kW *2 hour =20000 kW. 20000, the capacity of power / DC 192V=104AH single battery. 192V is the voltage connected by 16 batteries. The voltage of KELONG battery is 12V, that is 12v*16 only =192V.

So for example, a 8 kW load, a backup time of 2 hours, a 10 kW UPS power supply, and 16 KELONG batteries with a 12V capacity of 104AH.
