Abstract: Methods for arc detection in a system including one or more photovoltaic generators, one or more photovoltaic power devices and a system power device and/or a load connectible to the photovoltaic generators and/or the photovoltaic power devices. The methods measure voltage, voltage noise and/or power delivered to the load or system power device. The methods may compare one or more measurements, an aggregation of measurements and/or values estimated from the measurements to one or more thresholds, and upon a comparison indicating a potential arcing condition, an alarm condition may be set. Embodiments include an arrangement of photovoltaic generators and photovoltaic power devices for reduced-impedance voltage loops which may enhance arc-detection capabilities.

Abstract: Various implementations described herein are directed to a methods and apparatuses for disconnecting, by a device, elements at certain parts of an electrical system. The method may include measuring operational parameters at certain locations within the system and/or receiving messages from control devices indicating a potentially unsafe condition, disconnecting and/or short-circuiting system elements in response, and reconnection the system elements when it is safe to do so. Certain embodiments relate to methods and apparatuses for providing operational power to safety switches during different modes of system operation.

Abstract: Methods for arc detection in a system including one or more photovoltaic generators, one or more photovoltaic power devices and a system power device and/or a load connectible to the photovoltaic generators and/or the photovoltaic power devices. The methods may measure voltage, current, and/or power delivered to the load or system power device, and the methods may measure voltage noise or current noise within the photovoltaic system. The methods may periodically, and/or in response to detecting noise, reduce an electrical parameter such as current or voltage in order to extinguish an arc. The methods may compare one or more measurements to one or more thresholds to detect arcing, and upon a comparison indicating that arcing is or was present, an alarm condition may be set.

Abstract: A method for arc detection in a system including a photovoltaic panel and a load connectible to the photovoltaic panel with a DC power line. The method measures power delivered to the load thereby producing a first measurement result of the power delivered to the load. Power produced by the photovoltaic panel is also measured, thereby producing a second measurement result of power produced by the photovoltaic panel. The first measurement result is compared with the second measurement result thereby producing a differential power measurement result. Upon the differential power measurement result being more than a threshold value, an alarm condition may also be set. The second measurement result may be modulated and transmitted over the DC power line.

Abstract: A network unit may be operatively attached to power lines of an interconnected power system and/or a device such as a power module that may further include a communication interface. The network unit may be operable to superimpose a first signal representative of a sensed parameter of the power system onto the power lines, thereby to transmit the first signal to other power modules in the interconnected power system or to a power device in interconnected power system. The network unit may receive a second signal of the parameter superimposed onto the power lines from another network unit.

Abstract: An apparatus comprising a signal transformer coupled to a power line and a signal transmission, reception, or detection circuit. A sensor is configured to be responsive to the power line current or magnetic flux generated in a ferrite core of the signal transformer. When the sensor indicates that the flux generated by the power line current mat cause an attenuation of the signal strength, a second circuit generates a current through a flux cancelling winding that cancels at least some of the flux generated by the power line current.
