A 2,200-VA system costs about $700 and can power a router for about 18 hours.

How is UPS runtime calculated?

The formula commonly used is 10 times the capacity of the battery (in ampere hours) divided by the load of the device (in watts). The formula can be found on the label of the lead-acid battery. If you are using the device for a long time through the battery unit, it is recommended to charge the battery regularly.

How is UPS load calculated?

How to size a UPS

  1. List all equipment to be protected by the UPS. …
  2. List the amps and volts for each device. …
  3. Multiply the VA by the number of pieces of equipment to get the VA subtotals.
  4. Add the VA subtotals together.
  5. Multiply the total by 1.2 to get the grand total. …
  6. Use the grand total to select a UPS.

What is 1500VA?

1500VA indicates the UPS unit’s max instaneous output power. It means Volts x Amps, and there is no Hours implied in it. … 1500VA is the maximum output (voltage x current) of the unit. At 1500VA the backup would last 216 VA/H/1550VA = . 144 HR or 8 Minutes.

For a few hundred dollars you’ll find an entry-level UPS with a 550VA rating, supporting around a 330 Watt load, such as APC’s Back-UPS Pro 550. By APC’s own figures, this UPS can run 300 Watts worth of equipment for around four minutes.

What is UPS load percentage?

UPS efficiency is based on how much of the original incoming power is needed to operate the UPS. For example, an uninterruptible power supply with a 95% efficiency rating will have 95% of the original input powering the load and connected systems, with the remaining 5% energy “wasted” running the UPS.

What is half load runtime?

Look for a generator with a long run-time at half-load. The longer the generator can run, the less often you will have to refuel it. A generator with a run-time of at least 10 hours at half-load will allow you to get a full night’s sleep without having to get up to refuel.
