Solar panel transmitter pairing process
A system includes a modulator configured to generate a communication signal whose modulation represents coded information to be transmitted to a local management unit connected to a photovoltaic module. A local management unit is configured to receive a communication signal whose modulation represents coded information from an inverter or a transmitter. The local management unit is configured to receive a unique pairing sequence; pair to a first transmitter or inverter; and receive communications from the first transmitter or inverter. The local management unit is configured to ignore communications from a second transmitter or inverter that is not paired to the local management unit.

6. The system of claim 1 , wherein the local management unit is configured to start a pairing process in response to a current of a string being in a predetermined sequence.
7. The system of claim 6 , wherein the pairing device, the local management unit, or the pairing device and the local management unit is a transceiver.
8. The system of claim 1 , wherein the first transmitter or inverter is configured to receive wireless pairing information for connecting the first transmitter or inverter to the local management unit.
9. The system of claim 1 , wherein the local management unit is configured to start a pairing process the first time the local management unit is powered or in response to the local management unit being powered on and off in a predetermined sequence.
10. A system, comprising:
a modulator configured to generate a communication signal whose modulation represents coded information to be transmitted to a local management unit connected to a photovoltaic module; and
a local management unit configured to receive a power line communication signal whose modulation represents coded information from an inverter, a transmitter, or a pairing device, wherein the local management unit is configured to:
receive a unique pairing sequence;
pair to a first transmitter or inverter; and
receive communications from the first transmitter, inverter, or pairing device, wherein the local management unit is configured to ignore communications from a second transmitter or inverter that is not paired to the local management unit.
11. The system of claim 10 , wherein the pairing sequence is provided through a code that can be scanned or added to the local management unit using one or more of a smartphone, a tablet device, a wearable smart device, a laptop computer, a dedicated pairing device, or combinations thereof.
12. The system of claim 10 , wherein the first transmitter or inverter is configured to send the unique pairing sequence and the local management unit is configured to determine whether the unique pairing sequence received from the first transmitter or inverter matches a pairing code.
