A multiplicity of uninterruptible power supply (UPS) devices may be equipped with a plurality of sensors which report on the state of various operational parameters of the UPS devices to a registry device. Output of the registry device may be displayed on a dedicated GUI and/or written to log files at a monitoring station. In the event that one or more sensors reports a parameter to the registry device which is indicative of a malfunction of one or more of the UPS devices, examination the registry device output may indicate which UPS device or devices is/are malfunctioning. Related embodiments, apparatus, systems, and methods are also discussed.

Systems, methods and apparatuses for power systems and energy storage systems are disclosed herein. The system, or part thereof, may be configured to determine an operational plan for controlling device(s) (e.g., an energy storage device and/or a load device) such that the device(s) may increase their power consumption in response to an increasing voltage at a grid connection point thus reducing the probability that the voltage level at the grid connection point rises to or above an upper limit. The system, or part thereof, may identify external conditions that may cause harm to one or more energy storage devices (e.g., a battery pack). A controller (e.g., battery management system, or part thereof) may be used to determine critical external conditions or high-risk conditions based on sensor data, and/or to determine mitigation actions or send alerts. The system may comprise one or more energy storage devices that may be stacked together.

Disclosed is a containerized heating, ventilation, and air-conditioning (HVAC) system comprising an HVAC unit and one or more ducts from the HVAC unit to an equipment rack. The ducts prevent mixing between the fresh and exhaust airflow, thus improving efficiency. Sensors located at sources of heat generating equipment within the racks may be used by controllers to monitor temperatures of the components at the source of heat generation, typically at the highest temperatures. The temperatures may be aggregated to determine the temperatures of devices, modules, racks, and the container interior cavity. Dampers on the ducts, at the rack inlets, at the module inlets, at the devices inlets, and such may assist in regulating airflow preferentially to the hottest components, devices, modules, or racks.

A power system may comprise a plurality of power sources, each connected to a corresponding power regulator. The power regulators may be connected in series or in parallel, and may form a string. Each power regulator may comprise input terminals connected to the corresponding power source, output terminals, and a power converter that may be configured to convert input power from the corresponding power source to output power. The power regulator may further comprise a regulator communications module that may be configured to receive a power regulation indication relating to regulating an operational characteristic of the power regulator. The regulator controller may be configured to instruct the power converter to increase or decrease the regulator operational characteristic based on the power regulation indication, and based on power production characteristics of the power regulator.

Systems and methods are described herein for an electrical system comprising a battery energy storage system, a transformer, an alternating current interface, and an alternating current network coupled to the AC interface. The system may comprise a controller configured to maintain safe provision of power, such as by detecting an islanding condition. For example, the controller may detect changes in current associated with a power phase which are indicative of an islanding condition, disconnect portions of a circuit, detect voltage indicative of the islanding condition, and take responsive action.

A distributed power system including multiple (DC) batteries each DC battery with positive and negative poles. Multiple power converters are coupled respectively to the DC batteries. Each power converter includes a first terminal, a second terminal, a third terminal and a fourth terminal. The first terminal is adapted for coupling to the positive pole. The second terminal is adapted for coupling to the negative pole. The power converter includes: (i) a control loop adapted for setting the voltage between or current through the first and second terminals, and (ii) a power conversion portion adapted to selectively either: convert power from said first and second terminals to said third and fourth terminals to discharge the battery connected thereto, or to convert power from the third and fourth terminals to the first and second terminals to charge the battery connected thereto. Each of the power converters is adapted for serial connection to at least one other power converter by connecting respectively the third and fourth terminals, thereby forming a serial string. A power controller is adapted for coupling to the serial string. The power controller includes a control part adapted to maintain current through or voltage across the serial string at a predetermined value.

A method for a power system is disclosed. The method includes receiving signals, activating switches to pass a current from a power source to an apparatus. The method also includes deactivating switches and bypassing the power source. The power source may be a photovoltaic power source. The signals may be power line communication (PLC) signals.

A distributed power system including multiple DC power sources and multiple power modules. The power modules include inputs coupled respectively to the DC power sources and outputs coupled in series to form a serial string. An inverter is coupled to the serial string. The inverter converts power input from the serial string to output power. A signaling mechanism between the inverter and the power module is adapted for controlling operation of the power modules. Also, for a protection method in the distributed power system, when the inverter stops production of the output power, each of the power modules is shut down and thereby the power input to the inverter is ceased.
