A UPS has two ratings and the lower one is the limit. This unit is rated 3,000 VA and 2,700 W, so the equipment plugged into its battery outlets should draw no more than about 2,160 W if you want the usual 20% headroom. How to size a UPS.

Its weighted efficiency of 91.9% compares with a median of 93.1% across 95 certified units within 25% of its capacity. With nothing plugged in it still draws 51.5 W, about $59 a year at 13¢/kWh just to stand ready.
