An on-demand electric power system for providing on-demand electric power in remote locations. The on-demand electric power system generally includes a protective housing, an engine-generator within the protective housing, a control switch electrically positioned between the engine-generator and an electric load, and a control unit in communication with the engine-generator and the control switch to control operation of the engine-generator along with electrical power to the electric load. The control unit detects when electrical power is required by an electric load and then first starts the engine-generator. After a period of time, the control unit then closes the control switch to provide electrical power to the electric load.

1. Field of the Invention
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
FIG. 1 is a block diagram illustrating the on-demand electric power system in electrical communication with an electric load.
FIG. 2 is an upper perspective view of a protective housing.
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 8 illustrate an on-demand electric power system 10, which comprises a protective housing 20, an engine-generator 30 within the protective housing 20, a control switch 70 electrically positioned between the engine-generator 30 and an electric load 12, and a control unit 50 in communication with the engine-generator 30 and the control switch 70 to control operation of the engine-generator 30 along with electrical power to the electric load 12. The control unit 50 detects when electrical power is required by an electric load 12 and then first starts the engine-generator 30. After a period of time, the control unit 50 then closes the control switch 70 to provide electrical power to the electric load 12.
The present invention may be utilized to provide electrical power to various types of electric loads 12 in remote locations. For example, the electric load 12 may be comprised of a pump, an electric motor, particulate material auger, a fan, HVAC system, lights, irrigation pump, drain tile pump station and the like. As can be appreciated, there are no limits as to the types electric load 12 the present invention can be utilized with in remote locations. The electric load 12 may draw a constant or varying power.
FIGS. 2 through 4 illustrate a protective housing 20 for receiving and protecting the engine-generator 30, control unit 50 and related components of the present invention. The protective housing 20 includes a floor, one or more walls, a roof and at least one door 22. The protective housing 20 may be constructed of various types of materials including but not limited to metal (if constructed of metal, the protective housing 20 needs to be grounded).
