[0002] The present disclosure relates generally to power systems for electrical equipment and specifically to power supplies for frac equipment.
Background of the Disclosure
Background of the Disclosure
[0003] During frac operations, multiple pieces of frac equipment may be in continuous use.
Such equipment may include, for example, one or more blenders, hydrators, pumps, CAS, and belt loader systems as well as control systems for operating the equipment and infrastructure such as light plants for night operation.

Where power storage device 121 is sufficiently charged to allow for a desired period of operation of frac equipment 101 without need for operation of generator 111 as determined by load sensor 135 or by one or more user inputs, power controller 131 may turn off generator 111 if generator 111 is in operation [203], and may selectively electrically connect power storage device 121 to frac equipment 101 such that frac equipment 101 is operated on power from power storage device 121 [205].
