A UPS has two ratings and the lower one is the limit. This unit is rated 20 kVA and 20 kW, so the equipment plugged into its battery outlets should draw no more than about 16 kW if you want the usual 20% headroom. How to size a UPS.
Its weighted efficiency of 94.5% compares with a median of 95.6% across 45 certified units within 25% of its capacity. With nothing plugged in it still draws 143.0 W, about $163 a year at 13¢/kWh just to stand ready.
