A generator includes an internal combustion engine including an engine block including a cylinder including a piston, a crankshaft configured to rotate about a crankshaft axis in response to movement by the piston, and a spark plug configured to periodically generate a spark to ignite fuel in the cylinder to control the movement of the piston. The generator further includes an alternator including a rotor and a stator, the rotor configured to rotate with the rotation of the crankshaft to generate alternating current electrical power, a controller configured to control a rate of fuel supply to the internal combustion engine, and a switch configured to selectively enable the flow of a first type of fuel into the cylinder and disable the flow of a second type of fuel, wherein the controller is configured to receive an indication of a fuel type based on a position of the switch.

Inverter generator

A power management system for selectively providing power to one or more electrical loads using a standby generator includes a meter mounted transfer switch, a power management module, and a controller. The meter mounted transfer switch is configured to receive electrical power from a utility source. The power management module is configured to receive electrical power from each of the standby generator and the utility source. The controller is in communication with the standby generator and the power management module, and monitors a load on the standby generator and communicates to the power management module to selectively disconnect at least one of the one or more electrical loads based on the monitored load.

Power management system for a standby generator

A standby generator includes a standby housing defining a cavity and an internal combustion engine. The engine includes an engine block including a cylinder comprising a piston, an engine housing at least partially covering the engine block, and a crankshaft configured to rotate about a vertical crankshaft axis in response to movement by the piston. The standby generator also includes an alternator configured to generate alternating current electrical power, a controller comprising a rectifier configured to convert the alternating current to a direct current and an inverter configured to convert the direct current to a clean alternating current electrical power, and a transfer switch configured to receive the clean alternating current electrical power from the controller and at least one of grid, solar, or battery power, and configured to supply power to an electrical load. The internal combustion engine, the alternator, and the controller are positioned within the cavity.

The controller extends at least partially above the engine housing.

A power management system includes a generator, a meter mounted transfer switch, and a power management module. The generator includes a controller positioned in the housing of the generator. The generator connects to the power management module to provide power to one or more electrical loads. The controller is configured to selectively disconnect at least one of the electrical loads by communicating, via a wireless gateway, to a transfer switch of the power management module to move between first and second positions for connecting the generator to the one or more electrical loads.

Meter socket adapter with integral automatic transfer switch

A method and system for supplying electric power to a plurality of priority loads from either a utility power source or a secondary power source, such as a generator. A control unit monitors the power draw by each of a plurality of priority loads and base loads during the supply of electric power from the utility power source. When the supply of power from the utility power source is interrupted, the control unit determines the number of the priority loads that can be powered by the secondary power source based on the monitored power draw of the priority and base loads prior to power interruption. The secondary power source is activated and the determined number of priority loads is immediately connected to the secondary power source without delay. When the utility power source returns, the system and method transfers utility power back to all of the priority and base loads.

Power management transfer system and method

A transfer switch and load controller that can be plugged into an existing utility meter socket and electrically positioned between the meter socket and a distribution panel to allow switching between utility power and standby power. The plug-in transfer switch functions to transfer the power supplied to a home between the utility power source and the generator power source upon loss of power from the utility power source. The transfer switch components are contained in an enclosed housing of a meter socket adapter that is mounted directly to the meter socket of a meter housing. The meter socket adapter is prewired to a standby generator such that the standby generator can be connected to a home power system by plugging the meter socket adapter into the meter socket.

Meter socket adapter with integrated automatic transfer switch

A transfer switch panel including a bonded neutral connection to ground that allows the connection and disconnection of the utility neutral and an auxiliary power source neutral in one switching movement. The transfer switch panel includes a transfer switch connected to both a utility power source and an auxiliary power source. The transfer switch connects either the utility power source or the auxiliary power source to a pair of hot buses and a neutral bus contained within the transfer switch panel. The neutral bus includes a bonded connection to ground such that the neutral line of either the utility power source or the auxiliary power source is connected to ground when providing power to loads connected to a load center panel.

Transfer switch with neutral disconnect

A backup power management system connectable to a primary power source and a secondary power source, and a method of operating the same. The system includes an enclosed housing that receives a control system including first and second controllers that are connected to a first transfer switch contactor and a second transfer switch contactor within the housing. Both the primary power source and a secondary power source are broken into two separate output supplies. The two separate output supplies from the primary power source and the secondary power source are each provided to one of the first and second transfer switch contactors. The control system sends signals to the first and second transfer switch contactors to control the movement of the contactors between first and second positions. The power management system can also include a load management controller to control the load on the secondary power source.

Paralelling of two transfer switches

A method and system for managing electrical loads on a standby generator. The method includes utilizing a transfer switch control to selectively shed loads each associated with one of a series of priority circuits. Priority values are initially assigned to each of the electric loads based upon the initial hard-wired connection of the electric loads to a main breaker panel during set up. The control unit of a transfer switch allows the user to reassign priority values to each of the electric loads based upon a user preference. The control unit includes one or more predefined priority assignment programs that can be selected to modify the priority values assigned to the electric loads.

Dynamic load shedding system for a standby generator

A generator for providing electric power. The generator includes an engine associated with an alternator. Rotation of the engine causes the alternator to generate an AC source voltage that is fed to at least one analog output receptacle. The generator further includes an inverter connected to receive the AC source voltage and generate a digital AC output voltage having a constant voltage value and a constant frequency. The inverter allows the engine to operate at less than full speed when an electric load is drawing a relatively low amount of power from the generator. The analog receptacle allows larger electric loads to be connected to the generator where the electric loads cannot be supported by the digital AC output voltage.

Portable power supply having both inverter power supply and traditional power supply receptacles

A backup power management system connectable to a primary power source and a secondary power source, and a method of operating the same. The system includes a single controller that is connected to both a first transfer switch contactor and a second transfer switch contactor. Both the primary power source and a secondary power source are broken into two separate output supplies. The two separate output supplies from the primary power source and the secondary power source are each provided to one of the first and second transfer switch contactors. The single controller sends signals to the first and second transfer switch contactors to control the movement of the contactors between first and second positions. In this manner, the single controller controls both the first transfer switch contactor and the second transfer switch contactor.
