UPS units listed at 1500 VA or higher
These UPS units list 1500 VA or higher. VA is apparent power, not the same as output watts, and this page does not estimate battery runtime. A 1500 VA class still has to cover your load in watts with headroom. Use the UPS size calculator for a watts-and-VA planning figure, then confirm the listed watt rating on the product page.

How Many VA Do I Need in a UPS?
Calculate the UPS capacity you need by totaling your equipment’s watts, converting watts to VA using power factor, and adding practical headroom. A UPS must meet both its VA and watt limits, while runtime requires a separate battery check.
Read guideUPS Sizing Calculator: Watts, VA and Runtime
Size a UPS systematically by adding the protected load, converting between watts and VA, allowing headroom, and checking runtime separately. This guide includes a worked example and a practical UPS sizing checklist.

VA
VA means volt-amperes, a measure of apparent power. It describes the electrical capacity a product can handle, but it is not the same as watts, which measure real power.
Open termwatts
Watts are a unit of electrical power. On a UPS product page, a watt rating usually indicates how much connected equipment the unit can support or how much power a device uses, depending on the label.
Open termpure sine wave
Pure sine wave is an AC output waveform that closely follows utility power. It can be important for equipment that requires, or works better with, a smooth and consistent waveform.
