Abstract: A hybrid power system integrates with or supplements an existing diesel-powered generator set including a frequency converter with an input rectifier and an output inverter. A bidirectional DC-DC power converter and a battery are coupled to a DC bus between the rectifier and inverter. A controller receives sensor inputs associated with inverter output power to a load and a charge state of the battery. The controller is configured, upon determining a first charge state of the battery, to disable DC power from the rectifier to the DC bus, and to enable discharge of energy stored on the battery to the inverter via the DC bus. The controller is further configured, upon determining a second charge state of the battery, to reestablish DC power from the rectifier to the DC bus, and to direct energy from the DC bus for energy storage on the battery via the DC-DC power converter.

Abstract: A self-contained conveyable power unit for producing 12V/24V, 110V AC, and 220V AC electricity at a desired location independent of external power sources integrates within one weather-resistant molded nonmetallic material based housing a power generating device of a selectable combination of a renewable energy type and power storage devices. Additional optional power generating devices, renewable or of traditional fuel type, can be contained within or coupled to the housing. The system and housing are modular and configured to produce power using any combination of renewable and non-renewable energy resources. Given its molded composite material construction and scaleable design, the appliance may be readily fabricated in a variety of sizes for varied applications. Further, the molded housing of composite material construction is designed for resistance to the elements, light weight and strength.

Abstract: A self-contained conveyable power unit for producing 12V/24V, 110V AC, and 220V AC electricity at a desired location independent of external power sources integrates within one weather-resistant molded nonmetallic material based housing a power generating device of a selectable combination of a renewable energy type (e.g., solar), power management devices, power storage devices and management reporting devices. Additional optional power generating devices, renewable or of traditional fuel type, can be contained within or coupled to the housing. The system includes devices or an array of devices contained within the housing for the storage of electrical power. A device for power management is contained within the housing as is networking equipment of wireless or wired type for remote system observation and reporting. The system and housing are modular and configured to produce power using any combination of renewable and non-renewable energy resources.
