Embodiment Construction

[0054] In the following description of various illustrative embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various embodiments in which aspects of the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present disclosure.

[0055] Monitoring of the PV installation may include data collected by a central control system that monitors the power output by the PV installation and identifies potentially problematic operating conditions or safety hazards. When a facility experiences a power loss, it may be necessary to determine whether it is due to environmental conditions or originating from malfunction and / or poor maintenance of components of the PV facility. Furthermore, there may be a need to easily physically locate specific modules (eg solar panels, DC-DC con...

Abstract

Various implementations described herein are directed to a method for determining an order of power devices connected in a serial string. A command is transmitted, to at least one first power device of a plurality of power devices, to change an output electrical parameter. At least one electrical signal is caused to be transmitted from at least one second power device of the plurality of power devices. At least one measured value responsive to the electrical signal is received from at least one of the plurality of power devices. A determination is made, by analyzing the at least one measured value, which ones of the plurality of power devices are ordered in the serial string between the at least one first power device and the at least one second power device.
