Abstract: Various implementations described herein are directed to a method for recording, by a device, identifying information of a plurality of components of a photovoltaic (PV) installation. The method may record, by the device, at least one of timestamps or locations corresponding to each component of the plurality of components. The method may generate, based on the identifying information, timestamps, and locations, a map of the PV installation.

Abstract: Systems and/or methods for mapping power device in a string of serially connected power devices are disclosed herein. A power source may apply a source voltage to a first end of the string. A power system controller coupled to the two ends of the string may send a first signal to the power devices in the string. The power devices in the string, responsive to receiving the first signal, may measure electrical characteristics of the power devices, where the measured electrical characteristics may indicate the parasitic leakage of the power devices. The power devices may send second signals to the power system controller to report the measured electrical characteristics. The power system controller may determine the mapping of the power devices in the string based on the second signals.

Abstract: Systems, apparatuses, and methods are described for calibration of a current transformer. In some examples, one or more electrical elements may be affected in order to set a calibration of the current transformer. A calibration circuit of the current transformer may be permanently or non-permanently affected according to a calibration code in order to set the calibration of the current transformer. For example, one or more fuses may be burned to lock in a certain configuration of the current transformer.

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: 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.
