Pairing of components in a direct current distributed power generation system
First Claim
1. A method comprising:
- limiting current from an output of a photovoltaic module;
receiving an initial signal at the photovoltaic module;
receiving a control signal at the photovoltaic module;
validating a control code received in the control signal against an initial code received in the initial signal; and
commencing, in response to the validating of the control code, generation of current on the output of the photovoltaic module.

Abstract
A method of signaling between a photovoltaic module and an inverter module. The inverter module is connected to the photovoltaic module. In an initial mode of operation an initial code is modulated thereby producing an initial signal. The initial signal is transmitted from the inverter module to the photovoltaic module. The initial signal is received by the photovoltaic module. The operating mode is then changed to a normal mode of power conversion, and during the normal mode of operation a control signal is transmitted from the inverter to the photovoltaic module. A control code is demodulated and received from the control signal. The control code is compared with the initial code producing a comparison. The control command of the control signal is validated as a valid control command from the inverter module with the control command only acted upon when the comparison is a positive comparison.
