A battery operated standby power system, including a microboard; at least two rechargeable batteries mounted to the microboard; a charger for selectively charging the at least two batteries; at least two, or dual, inverters, one inverter being assigned to each of the at least two batteries; a plurality of outlets, the outlets being configured to selectively deliver 120 VAC, 240 VAC and both 120 and 240 VAC from the batteries through the inverters.

A distributed control node enables local control of reactive power. A metering device of the control node measures energy delivered by a grid network at a point of common coupling (PCC) to which a load is coupled. The metering device determines that the load draws reactive power from the grid network. The control node draws real power from the grid and converts the real power from the grid into reactive power. The conversion of real to reactive power occurs on the consumer side of the PCC. The conversion of real to reactive power enables delivery of reactive power to a local load from real power drawn from the grid.

Example implementations relate to power delivery monitor and control with an uninterruptible power supply (UPS). For example, a UPS includes a power output receptacle to supply power to a power extension bar coupled to the UPS via a power cable, the extension bar to provide the power to a plurality of computing devices coupled to the extension bar. The UPS also includes a data communication port to couple the UPS to the extension bar via a communication cable, and a controller module to monitor and control power delivered to a plurality of power output receptacles on the extension bar.

A household distribution box comprises a distribution box case; two service lines introduced from a transformer into the distribution box case of a consumer; three main lines installed in the distribution box case and provided with two lines and a second service line; two sub-lines installed in the distribution box case and formed by branching the second service line among the main lines into two lines; a first circuit breaker installed in the distribution box case; a second circuit breaker installed in the distribution box case; and a controller connected to the first circuit breaker.

A system includes: an energy storage device capable of storing electric power in a predetermined form; and a control device including a control unit that controls the energy storage device. The control unit controls the energy storage device based on output restriction information on an output-restricting period during which output of electric power from a power generation facility operated in conjunction with an electric power system to the electric power system is restricted, such that the electric power generated in the power generation facility is stored in the energy storage device during the output-restricting period.

A power device includes an input configured to receive input power from a power source, power circuitry, a power output, a network module, and a controller. The controller is configured to operate the power circuitry to provide output power to the power output derived from the input power and to communicate with at least one primary server via the network module. In response to a determination that communication with the primary server has failed, the controller is configured to attempt communication with a domain name server. In response to a determination that communication with the domain name server has failed, the controller is configured to identify that the network has failed.

Systems, methods and apparatuses are provided for reducing peak energy demand and to smooth intermittent energy profiles from onsite variable energy sources and loads. Some embodiments use system level and device level analysis and optimization to adaptively adjust the operation of a behind the meter energy storage (BMES) to smooth out energy generation variabilities and follow a reference load signal, including at short time resolutions.

A method (3600) and system (2800, 2900, 3000, 3100) autonomously create a restore point for a luminaire controller (2810, 3110) and restore it to proper operation when required. The luminaire controller operates by using first operating software having a first software image, and receives a second software image of second operating software. The luminaire controller communicates the first software image to a first device (2820, 3120) connected to the luminaire controller via a communication network (2805, 3105), installs the second operating software, and performs a self test of the luminaire controller. If the luminaire controller fails the self test, the luminaire controller requests via the network that the first device transfer the first software image to the luminaire controller via the network, receives the first software image, installs the first operating software, and reverts to operation with the first operating software.

Apparatuses including power electronics circuitry are provided. The power electronics circuitry includes at least one power converter that is coupled to a DC bus. Moreover, in some embodiments, the at least one power converter is configured to regulate a voltage of the DC bus. Related methods of operating an apparatus including power electronics circuitry are also provided.
