摘要： The disclosure describes a method for detecting an arc in a direct-current (DC) circuit comprising a DC load, a DC source supplying the DC load, and a circuit arrangement arranged between the DC source and the DC load. A power flow P between an input and an output of the circuit arrangement is suppressed by means of a switching circuit through cyclical interruption such that the power flow P is enabled in an active time window with the first period Δt1 and the power flow P is suppressed in an inactive time window with the second period Δt2. Via detection of an input current Iin flowing at the input and/or an input voltage Uin applied to the input and comparison of values of the input current Iin and/or input voltage Uin detected in the inactive time window with a current threshold value ITH or a voltage threshold value UTH an arc presence criterion is signaled if the input current Iin detected in the inactive time window falls below the current threshold value ITH and/or the input voltage Uin detected in the inactive time window does not exceed the voltage threshold value UTH. The application also describes a circuit arrangement for detecting an arc and a photovoltaic (PV) inverter including such a circuit arrangement.

摘要： A device comprises a platform constructed and arranged to be mounted to one or more solar array modules and one or more solar irradiance sensors on the platform configured to receive incident solar energy, the one or more solar irradiance sensors oriented on the platform so that the received incident solar energy is comparable to that received by the solar array modules, the one or more solar irradiance sensors providing solar irradiance signals in response to the incident solar energy. A processor is on the platform, the processor configured to receive the solar irradiance signals and, in response, generating a performance reference metric based on the solar irradiance signals, the performance reference metric related to the expected performance of the one or more solar array modules to which the platform is mounted. A transmitter is on the platform, the transmitter configured to periodically transmit the performance reference metric to a receiver.

摘要： A system and method for automated shutdown, disconnect, or power reduction of solar panels. A system of solar panels includes one or more master management units (MMUs) and one or more local management units (LMUs). The MMUs are in communication with the LMUs with the MMUs and LMUs “handshaking” when the system is in operation. The MMUs are connected to one or more controllers which in turn are connected to emergency detection sensors. Upon a sensor detection of an emergency, the associated MMU is notified which in turn instructs associated LMUs to take appropriate action. In the event that communication with the MMUs has been cut off, the LMUs take the initiative to shut down, disconnect, or reduce the output of associated string(s) of solar panels.

摘要： Methods for controlling an integrated renewable energy source (RES) and energy storage system (ESS) of a RES-ESS facility having a point of grid interconnect (POGI) limit are provided. A forecast for energy production of the RES as well as a state of charge (SOC) schedule are used to calculate a SOC target-based POGI cap that is less than the POGI limit, with the SOC target-based POGI cap representing as low a peak power output value as possible while still ensuring satisfaction of the SOC schedule. The forecasted RES production, SOC schedule, and SOC target-based POGI cap are used to generate a time-varying charge/discharge control signal for the ESS that ensures the SOC schedule is satisfied.

摘要： A rapid shutdown device (RSD) includes: a logic-and-analog circuit; an RSD ID storage for storing an unique RSD ID; a control command receiving circuit for receiving and decode a control command including a combination of an all-RSD turn-on command, a single-RSD turn-on command and a to-be-tested RSD ID; a switch circuit connected to the logic-and-analog circuit; and a bypass circuit connected between two output terminals of the RSD. When the switch circuit is turned off, the bypass circuit is turned on. The logic-and-analog circuit controls the on/off state of the switch circuit according to a decoding result of the control command receiving circuit and the unique RSD ID stored in the RSD ID storage. When the switch circuit is turned on, an output voltage received from a photovoltaic module coupled to the RSD is outputted via the RSD.

摘要： According to one embodiment, an electronic apparatus includes a processor. The processor is configured to acquire n installation positions where first to n-th pieces of equipment are installed, receive a propagation characteristic related to the first to n-th pieces of equipment, and estimate, by an algorithm, a combination or the first to n-th pieces of equipment and each of the n installation positions based on a propagation characteristic related to the first to n-th pieces of equipment. An initial value of the algorithm is generated based on an arrangement of the n installation positions and an arrangement of the first to n-th pieces of equipment determined based on a propagation characteristic related to the first to n-th pieces of equipment.

摘要： The present application describes machines and methods that leverage enabling technologies such as robotics, sensing, machine learning, and wireless internet coverage (e.g., 5G cell coverage) in order to monitor photovoltaic systems such as solar sites. Machines according to the present disclosure can be operated remotely by users to traverse a solar site and perform a series of inspection steps, such as via an online portal. Autonomous and semi-autonomous operations are also possible. These methods and machines can eliminate the need for a technician to visit the site in person for routine inspection, and can provide better information when a site alarm is triggered so that if a technician does need to visit the site, he or she is better prepared. Also described herein are systems and methods for inventorying solar sites, and systems and methods for inspection of structure-mounted photovoltaic systems.
