How long will a 2000 VA UPS last?
approximately 45 minutes
Therefore, with a load of 500W, the 2kVA will last for 0.75168 hours ( approximately 45 minutes ). [bctt tweet=”For example, a 2kVA Online UPS with a load of 200W will last about three times longer than another one with a load of 800W.”]
How long will a 1500VA battery backup last?
It’s indicating a runtime of around 390 minutes, so the 1500VA model should be able to do about 1.5 times that — call it 9.5 hours!
What does VA mean in battery backup?
volt-amperes
UPS battery backup are given a power rating in volt-amperes (VA) that range from 300 VA to 5,000 kVA. This rating represents the maximum load that a UPS can support, but it shouldn’t match exactly the power load you have.
How many VA do I need?
As a very rough rule of thumb, the wattage rating of a UPS is approximately 0.6 * its VA rating so, as you have seen, a 700VA UPS is good for a power load of around (0.6 * 700) = 420W (your specs said 405W). Conversely, the minimum VA rating you need is approximately 1.6 * load wattage.
How do I choose a UPS battery backup?
The more power that is consumed, the less time the UPS will be able to power everything. When choosing a UPS, it is generally recommended you chose one with an output watt capacity 20-25% higher than the total wattage of the devices you want to connect. You can use the UPS watts calculator to determine your total load.
What is VA in inverter?
A volt-ampere (VA) is a measurement of power in a direct current (DC) electrical circuit. The VA specification is also used in alternating current (AC) circuits, but in this case, it represents apparent power (represented in VA), which often differs from true power (represented in watts).

How do you calculate VA of a battery?
Battery Bank Voltage = 24V DC….Step 1: Calculate Total Load:
- Fan Load= No x Watt =2×60=120 Watt.
- Fan Load=(No x Watt)/P.F=(2×60)/0.8= 150VA.
- Computer Load= No x Watt =1×200=200 Watt.
- Computer Load=(No x Watt)/P.F =(1×200)/0.8= 250VA.
- Tube Light Load= No x Watt =2×30=60 Watt.
- Tube Light Load=(No x Watt)/P.F =(2×30)/0.8= 75VA.
