A UPS has two ratings and the lower one is the limit. This unit is rated 11 kVA and 10 kW, so the equipment plugged into its battery outlets should draw no more than about 8,000 W if you want the usual 20% headroom. How to size a UPS.
Its weighted efficiency of 94.9% compares with a median of 95.0% across 47 certified units within 25% of its capacity. With nothing plugged in it still draws 1.1 W, about $1.22 a year at 13¢/kWh just to stand ready.
