A device includes a network interface and a processor. The network interface is configured to receive one or more preferences of a customer related to the charging of at least one backup device of the consumer. The network interface is also configured to receive at least one notification of at least one predicted power disturbance. The processor is configured to utilize the one or more consumer preferences and the at least one notification to generate a charging schedule of the at least one backup device and to generate one or more charging notifications for charging the at least one backup device. The one or more charging notifications are based on the charging schedule.

A electrical distribution system has been developed to provide a remote central control point for individual circuits, and methods have been developed for retrofitting it to existing service panels or installing it into new service panels. This system provides a power circuit monitoring and control system that fits inside standard residential service panels, both new and retrofitted panels. The entire system can be retrofitted into existing breaker panel systems without the need of removing any permanent structure such as a wall. During this retrofit process, the panel cover on the existing distribution panel is first removed after the power to it is disconnected. The old breaker assembly is removed from the panel, and a circuit controller is then installed in the now available space within the panel. A new service panel enclosure with a circuit breaker assembly is installed directly over top of the enclosure.

Systems, apparatuses, and methods for a modular inverter system having a system controller module that includes several electronic switches that may be controlled to couple various nodes in the system controller module to various circuits coupled to input/output terminals at the modular inverter system to realize various modes of operation. Such modes of operation may include powering a local load (e.g., a house) with locally generated power as well as charging a local battery stack and selling excess power to a utility company that provides a grid tie-in. Such control may be automated based on monitoring various control signals or may be manually invoked by a system operator.

Techniques for provisioning energy generation and/or storage systems. In one embodiment, a method is provided that can comprise automatically determining, by a site gateway, information pertaining to one or more components of an energy storage system, where the site gateway and the one or more components are located at a customer site. The method can further comprise configuring, by the site gateway, the energy storage system based on the automatically determined information.

Methods, systems, and apparatus are disclosed which include receiving an indication of a floor plan of a building project; receiving an indication of an inspection report, the inspection report associated with an inspection type; identifying a forecast date associated with each room in the floor plan, the forecast date indicating when an inspection type associated with the respective room is to be completed; for each room, determining how close each room's forecast date is to a present date, and if the room's forecast date is past the present date; generating a visual map of the floor plan; associating a color of each room in the floor plan based on the determining; and providing the visual map with the associated color of each room for display.

A demand side electric power supply management system is disclosed. The system comprises an islanded power system having a point of coupling to a supply grid. The islanded power system supplies a plurality of electric loads, each of which is associated with a load controller to control the maximum power demanded by that load. A measuring means associated with the point of coupling measures the total power transfer between the grid and the islanded system, and a system controller monitors the measured power transfer relative to a set point and provides a control signal to a plurality of load controllers. Each load controller receives substantially the same control signal and determines the maximum power which the or each load associated with the load controller is allowed to draw from the islanded power system based on information contained in the control signal.

A method for controlling an electrical installation from a remote control station is provided, the installation including a coupling network powering one or more electrical loads, a main switch to connect a main power source to the network, and an auxiliary switch to connect an auxiliary power source to the network, the method including synchronizing the auxiliary power source with the main power source including a phase of measuring electric data relative to the main power source and to the auxiliary power source and a verification phase, from the remote station, to ensure that the measured data relative to the main and auxiliary power sources is compatible; sending an order to close the auxiliary switch from the remote control station; sending an order to open the main switch from the remote station; and checking, from the remote station, that the loads are correctly powered by the auxiliary power source.

Methods and systems are described for power state management. A critical usage window may be configured at a gateway node. A change in a power state of the gateway node may be detected, at an interface, during the critical usage window. The power state of the gateway node may be adjusted via the interface for a set duration using a backup power node.

An isolated DC power supply device that supplies direct current (DC) power via a positive electrode line, a negative electrode line, and a neutral line to which a signal is applied, the isolated DC power supply device including: an amplifying unit configured to amplify the DC power; a receiving unit configured to detect an occurrence of a ground leakage current flowing to the positive electrode line or the negative electrode line, compare a voltage of the neutral point with a voltage of the signal of the neutral line and connect the neutral line with a ground point via a coil; and an impedance adjusting circuit configured to be installed between the amplifying unit and the receiving unit and adjust an impedance in a voltage range of the signal applied to the neutral line and in a voltage range other than the signal voltage range.

A hub device controls an electrical energy state of one or more appliances, and controls an alternative electricity supply such as a solar generation installation whose output is non-constant such that sometimes the electrical energy available from the alternative electrical supply is greater than the electrical energy demand from the appliances, and at other times the electrical energy available from the alternative electrical supply is less than the electrical energy demand from the appliances. The hub device may control the alternative electricity supply and/or the appliances such that the electrical energy available from the alternative electrical supply is matched to the electrical energy demand from the appliances.
