Hi
These are the specifications of UPS system being used:
DC input 12V
AC output 220V, 50Hz
10A/20A charging current
Power factor 0.6
Power 1 kVA
Modified sine wave
The battery being used is 12V, 175Ah.
Q1:
If I go with mathematical calculation then I would say that the UPS could only supply 600W because power factor=real power/apparent power. I am still confused. Why does the UPS system have such a low power factor for itself? I had that it's a load which dictates power factor and not the supply (which in our case is UPS system). Even generators tend to have unity power factor.
Note to self: The inverter used in the UPS system could only produce 600W.
Q2:
Although at the moment only one battery is being used, I think that another 12V battery could be connected in parallel to the present battery. But connecting a second battery would take the system a little longer to get fully charged.
i: Do I have it correct?
ii: Should the other battery also be of 175Ah because the one being used in 12V, 175Ah?
Please help me with the queries. Thank you.
Regards
