How much battery backup UPS gives?
For devices that consume a high amount of power, this UPS offers a battery backup of around 28 minutes and for low power consuming devices, it can offer a backup for 3 hours continuously. Thus, you can always rely on this backup system.
What is a UPS rating?
Some uninterruptible power supply (UPS) systems are rated in kilowatts (kW) and others in kilo-volt-amperes (kVA). KW and kVA simply mean 1,000 watts (W) or 1,000 volt-amperes. For years, large UPS systems were designed based on a PF of 0.8, which meant that a 100 kVA UPS would only support 80 kW of real power load.
What wattage UPS do I need?
When sizing a UPS for your specific requirements, the power factor matters most. Generally, your UPS should have an Output Watt Capacity 20-25\% higher than the total power drawn by any attached equipment.

How many batteries does it take to power a ups?
The UPS battery bus voltage is 480 V. The typical table is for 12 V batteries (six cells of 2 V each). Quantity of batteries per bank = 480/12 = 40 batteries. Number of cells per bank = 40 x 6 = 240 cells. Looking at the capacity, we see that the required watt/cell is too much for one bank.
