A microgrid system controller includes a regulated bus, a variable-frequency drive (VFD) inverter, a generator coupled to a rotatable flywheel, a resistive load; and a plurality of actuatable switches. The microgrid system controller may also include a battery and charge controller or a battery storage device. The plurality of actuatable switches couple some of the various components.

An energy management system (401) for a kitchen appliance (201), the energy management system (401) comprising: a mains power system, a backup energy storage system (405), and a con-troller (411), wherein the controller (411) is arranged to: determine a state of health of the energy storage system; determine a state of charge of the energy storage system; determine how energy from the energy storage system is to be used based on the determined state of health, the determined state of charge and at least one measured variable obtained from a kitchen appliance (201), and apply the energy to operate at least one function of the kitchen appliance (201).

Systems and methods are disclosed for communicating with and controlling load control systems of respective user environments from locations that are remote from the user environments.

A power controller configured to fit in a circuit breaker panel powering one or more loads. The power controller is further configured to dynamically manage critical loads of the one or more loads each controlled by a component that is capable of being actuated by the power controller and operated from a smartphone via the power controller, wherein the critical loads need not be wired to a dedicated circuit breaker panel.

A control system (300) allows recognized standard premise electrical outlets, for example NEMA, CEE and BS, among others to be remotely monitored and/or controlled, for example, to intelligently execute blackouts or brownouts or to otherwise remotely control electrical devices. The system (300) includes a number of smart receptacles (302) that communicate with a local controller (304), e.g., via power lines using the TCP/IP protocol. The local controller (304), in turn, communicates with a remote controller (308) via the internet.

This disclosure is directed to generator systems and methods for monitoring a direct current bus and automatically operating in response to a power level of the direct current bus dropping below a desired power level or to a threshold before dropping below the power level. The automatic operation of the generator system may raise or keep the actual power level of the system above the desired power level or threshold.

An integrated energy optimizer having an edge side and a cloud side. The edge side may incorporate an energy optimizer, a building management system connected to the energy optimizer, a controller connected to the building management system, and equipment connected to the controller. The cloud side may have a cloud connected to the energy optimizer and to the building management system, and a user interface connected to the cloud. Data from the field sensor may go to the optimizer and the building management system. The data may be processed at the optimizer and the building management system for proper settings at the building management system.

The present disclosure provides an electrical system that includes an energy control system, a photovoltaic (PV) power generation system electrically coupled to the energy control system, an energy storage system electrically coupled to the energy control system, and a smart load panel electrically coupled to the energy control system and to a plurality of backup loads. The energy control system operates in an on-grid mode electrically connecting the PV power generation system to a utility grid and a backup mode electrically disconnecting the PV power generation system from the utility grid. The smart load panel selectively disconnects one or more of the plurality of backup loads from the energy control system when the energy control system is in the on-grid mode and when the energy control system is in the backup mode.

The clamp on power cord USB charger is an electric energy distribution device. The clamp on power cord USB charger draws ac electric energy from the national electric grid by tapping into the cable of an electric device. The converts the drawn ac electric energy into dc electric energy. The clamp on power cord USB charger distributes the dc electric energy in a manner suitable for use by USB devices. The clamp on power cord USB charger comprises a pan, a lid, a fastening structure, and a rectifying circuit. The pan, the lid, and the fastening structure enclose the rectifying circuit. The rectifying circuit: a) taps into the cable to draw ac electric energy from national electric grid; and, b) converts the drawn ac electric energy into dc electric energy.
