Publication number: 20200279963Abstract: 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.
