| 20090058191 | TRANSFER SWITCH - A system for use with an electrical distribution panel having a bonded neutral connection. In some embodiments, the system includes a generator having a first bonded neutral connection and a ground fault circuit interrupter. The system also includes a neutral bus that is connected to either the bonded neutral connection of the distribution panel or the bonded neutral connection of the generator. Additionally, the system includes a switch for disconnecting the neutral bus from the bonded neutral connection of the distribution panel and connecting the neutral bus to the bonded neutral connection of the generator. | 03-05-2009 |
| 20090240377 | POWER MONITORING SYSTEM - The invention provides a hierarchically accessible monitoring system configured to be used with a standby generator, and a method of remotely accessing generator information from a standby generator. The hierarchically accessible monitoring system includes an interface unit configured to receive information from the standby generator and to communicate the generator information, and a remote data server in communication with the interface unit. The remote data server receives the generator information from the interface unit, stores the generator information, and controls access to the generator information based upon at least two hierarchical levels, each hierarchical level having different access privileges. The hierarchically accessible monitoring system also includes a user interface configured to display the generator information from the remote data server to at least one user. The user has access privileges to read the generator information based upon the user's assigned hierarchical level. | 09-24-2009 |
| 20100225167 | POWER MANAGEMENT SYSTEM AND METHOD OF OPERATING THE SAME - A power management system connectable to a primary power source and a secondary power source, and a method of operating the power management system. A transfer switch is electrically connected to the primary and secondary power sources, and a plurality of branch circuits are electrically connected to the transfer switch. The plurality of branch circuits includes a plurality of electrical outlets. The system includes a controller wirelessly coupled to a plurality of portable receptacles, which are coupled between respective electrical outlets and managed devices. The controller manages the receptacles, and consequently the managed devices, during the second power source powering the transfer switch. | 09-09-2010 |
| 20110054707 | SYSTEM AND METHOD FOR CONTROLLING POWER USAGE - A control system for a home generator includes circuitry configured to determine a first cost of electricity provided by an off-site provider, determine a second cost of electricity produced by the home generator, compare the first cost with the second cost, and provide the result of the comparison as an output. | 03-03-2011 |
| 20110175453 | METER SOCKET TRANSFER SWITCH - A control system for a home electrical system includes a first switch installed at a meter socket of a utility module for controlling flow of electricity from a utility source to an electrical load, a second switch installed in a home generator for controlling flow of electricity from the generator to the electrical load, and circuitry configured to actuate the first and second switches. The circuitry includes at least one interlock to provide power to the electrical load from only one of the utility source and the generator at any given time. | 07-21-2011 |
| 20110175597 | SIGNAL TESTING APPARATUS FOR LOAD CONTROL SYSTEM - A system for testing power line carrier signal integrity or strength in a building electrical system includes a transmitter module electrically coupled to a first electrical outlet and configured to transmit a power line carrier signal over the building electrical system. The system also includes a receiver module electrically coupled to a second electrical outlet and configured to receive the power line carrier signal from the transmitter module. The receiver module includes circuitry configured to determine whether at least one of the integrity and strength of the power line carrier signal is sufficient for a load control system installed in the building electrical system to communicate with relay modules installed in the building electrical system using power line carrier signals. The receiver module includes a user interface configured to provide an indication of at least one of the integrity and strength of the power line carrier signal. | 07-21-2011 |
| 20110260473 | METHOD FOR STANDBY GENERATOR RESTART AFTER FAULT SHUT-DOWN - A standby generator that includes a control unit that allows the standby generator to be automatically restarted upon termination of the generator operation due to a fault condition. The control unit of the standby generator monitors various conditions of the standby generator and terminates operation of the standby generator upon detection of any one of a plurality of fault conditions. After the generator operation has been terminated, the control unit determines whether the fault condition is one of a series of fault conditions that allows automatic restarting. If the fault condition allows for automatic restarting, the control unit monitors the status of the generator and will automatically restart the generator after removal of the fault condition. | 10-27-2011 |
| 20110298285 | ACTIVE LOAD MANAGEMENT SYSTEM - A method and system for managing loads powered by a standby generator. The method includes utilizing a transfer switch control unit to selectively shed loads each associated with one of a series of priority circuits. The loads are shed in a sequential order based upon the priority circuit to which the load is applied. Once a required load has been shed, the control unit determines whether any of the lower priority loads can be reconnected to the generator without exceeding the rating of the generator while one of the higher priority circuits remains open. | 12-08-2011 |
| 20110298286 | DYNAMIC LOAD SHEDDING SYSTEM FOR A STANDBY GENERATOR - 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. | 12-08-2011 |
