The battery system stores battery power. The inverter is operatively connected to the battery system. The transformer is operatively connected to the AC line, the load, and an inverter winding operatively connected to the inverter. The controller controls the inverter to supply power to the primary winding using battery power stored in the battery system based on a cost value indicative of reduction of life of the battery system. ## Claims ### Claim 1 An uninterruptible power supply adapted to be connected between an AC line and a load, comprising: a battery system for storing battery power; an inverter operatively connected to the battery system; a transformer operatively connected to the AC line, the load, and an inverter winding operatively connected to the inverter; and a controller for controlling the inverter to supply power to the primary winding using battery power stored in the battery system based on a cost value indicative of reduction of life of the battery system. ### Claim 2 (depends on 1) An uninterruptible power supply as recited in claim 1, in which the controller controls the inverter by measuring at least one characteristic of the battery system. ### Claim 3 (depends on 1) An uninterruptible power supply as recited in claim 1, in which the controller controls the inverter based on a quantification of reduction of overall life of the battery system and revenue associated with supplying power to the primary winding. ### Claim 4 (depends on 1) An uninterruptible power supply as recited in claim 1, in which the controller controls the inverter to operate in the third mode based on a quantification of reduction of overall life of the battery system and revenue associated with supplying power to a utility power source. ### Claim 5 (depends on 1) An uninterruptible power supply as recited in claim 1, in which the controller controls the inverter to operate based on: a margin calculated based on a quantification of reduction of overall life of the battery system and revenue associated with supplying power to the primary winding; and a determination of whether the margin is within predetermined parameters. ### Claim 6 A method of supplying power to a load, comprising the steps of: storing battery power in a battery system; operatively connecting an inverter to the battery system; providing a transformer; and operatively connecting the transformer to the AC line; operatively connecting the transformer to the load; operatively connecting the transformer to the inverter; controlling the inverter to supply power to the primary winding using battery power stored in the battery system based on a cost value indicative of reduction of life of the battery system. ### Claim 7 (depends on 1) A method as recited in claim 1, in which the step of controlling the inverter comprises the step of determining when at least one characteristic of a primary power signal is within certain predetermined conditions. ### Claim 8 (depends on 2) A method as recited in claim 2, in which the certain predetermined conditions include a price associated with the primary power signal. ### Claim 9 (depends on 2) A method as recited in claim 2, in which the step of determining when at least one characteristic of a primary power signal is within certain predetermined conditions includes the step of determining a price associated with the primary power. ### Claim 10 (depends on 7) A method as recited in claim 7, in which the step of determining when at least one characteristic of a primary power signal present at the primary winding is within certain predetermined conditions includes the step of measuring a voltage of the primary power signal. ### Claim 11 (depends on 6) A method as recited in claim 6, in which the step of operatively connecting the transformer to the AC line comprises the step of operatively connecting the transformer to a utility power source. ### Claim 12 (depends on 6) A method as recited in claim 6, further comprising the step of comparing a quantification of reduction of overall life of the battery system and revenue associated with supplying power to the primary winding. ### Claim 13 (depends on 6) A method as recited in claim 6, further comprising the steps of: calculating a margin based on a quantification of reduction of overall life of the battery system and revenue associated with supplying power to the transformer; and operating the controller based on a determination of whether the margin is within predetermined parameters. ### Claim 14 An uninterruptible power supply adapted to be connected between an AC line and a load, comprising: a battery system for storing battery power;
