Various implementations described herein are directed to systems, apparatuses and methods for operating stand-alone power systems. The systems may include power generators (e.g., photovoltaic generators and/or wind turbines), storage devices (e.g., batteries and/or flywheels), power modules (e.g., power converters) and loads. The methods may include various methods for monitoring, determining, controlling and/or predicting system power generation, system power storage and system power consumption.

The present disclosure is directed to energy storage and supply management system. The system may include one or more of a control unit, which is in communication with the power grid, and an energy storage unit that stores power for use at a later time. The system may be used with traditional utility provided power as well as locally generated solar, wind, and any other types of power generation technology. In some embodiments, the energy storage unit and the control unit are housed in the same chassis. In other embodiments, the energy storage unit and the control unit are separate. In another embodiment, the energy storage unit is integrated into the chassis of an appliance itself.

Systems, apparatuses, and methods for realizing a modular inverter system having an orientation of two or more DC busses and an AC bus disposed on the same backplane having peripheral interfaces for engaging one or more swappable modules. Such a modular inverter system includes a backplane having a first side and a second opposite side, the first side supports the DC busses and an AC bus while the second side includes a plurality of peripheral interfaces. One or more power modules may be engaged with the backplane through one or more peripheral interfaces. With the DC busses and the AC bus disposed on the opposite side of the peripheral interfaces, the power module is physically isolated from the back side of the backplane and allows for more than one local power generator to be coupled to the system.

A power saving control device includes: an acquirer that acquires a power saving request; and a controller that determines whether or not power saving control for reducing a power consumption of a load device is to be performed in response to the power saving request, and that, when determining that the power saving control is to be performed, performs the power saving control. When the load device consumes power, the controller determines that the power saving control is not to be performed under a condition that no power flows from a power system into a facility in which the load device is installed, the condition being one of one or more conditions.

Apparatuses, methods and storage medium associated with an intelligent LED light apparatus are disclosed herein. In embodiments, an intelligent LED light apparatus may include a communication interface, a processor, a body that encases at least the communication interface and the processor, and a plurality of sensors of a plurality of sensor types disposed on the body. The processor may be configured to receive sensor data from the sensors, and transmit the sensor data or results from processing the sensor data to an external recipient. Further, for some embodiments, the intelligent LED bulb apparatus may further comprise LED lights, and the body further encases the LED lights. In other embodiments, the body may include a male connector to mate with a bulb receptor, and a female connector to mate with a LED bulb. Other embodiments may be disclosed or claimed.

A power supply unit, an electrically operated system and a method for operating an electrical system, wherein the power supply unit connects through a basic supply voltage or a buffer voltage, which is provided by an energy store unit, where to perform a controlled switch-on process of the electrical loads, a switch-on delay time is specified, after the expiration of which the basic supply voltage or the buffer voltage is connected through at the output of the power supply unit, and where to perform a controlled switch-on process of the electrical loads, a voltage is output only when a charge level of the energy store unit is greater than or equal to a threshold value of the energy store charge level such that switch-on management for power supplies that ensures absolutely safe interruption-free and thus trouble-free start-up of a plurality of electrical loads is achieved.

Disclosed are systems and methods for adjusting environmental conditions based on automatically and manually generated requests. A commissioned unit comprising at least one IP luminaire (140, 150), transmits a signal comprising one or more identification codes. The signal may be, for example, a coded light signal. An environment control device (160) receives the signal, detects user input indicating one or more preferred environmental conditions, and transmits an environment control request comprising the one or more preferred environmental conditions. An environment manager module (110) receives the environment control request, generates an environment control command using the control request, and transmits the environment control command to one or more commissioned units to alter environmental conditions in a space in accordance with the user input.
