A method of controlling an uninterruptible power supply system to increase component life includes decreasing a maximum output power limit of the uninterruptible power supply system when a temperature that the uninterruptible power supply system is experiencing has increased and increasing the maximum output power limit when this temperature has decreased. In an aspect, this temperature is ambient temperature of an equipment enclosure of the uninterruptible power supply system in which at least a rectifier and inverter of the uninterruptible power supply system are located. In an aspect, the method further includes upon the system going into an overload condition, determining an overload time limit based upon the temperature, the overload condition and an initial load condition. In an aspect, the method further includes upon the system going into a back-up power mode, determining a battery autonomy based upon the temperature.
