kW vs kVADivide kW by output PF, then add 20–25%UPS runs at overload
Motor startingUse soft starter or higher overload frameTrips on start
Battery runtimeUse the discharge curve, not Ah ÷ currentRuntime shortfall
ChargerConfirm recharge current and timeBattery never fully recharged
Input currentSize breaker and cable for full load + chargingNuisance trips and heat
RoomCheck floor loading, ventilation and clearanceInstallation delay
