1. A method, comprising:
- attempting to communicate, from a first local management unit of a plurality of local management units, on a first active channel with a master management unit, each of the plurality of local management units coupled to control a respective solar module of a plurality of solar modules;
determining if communication with the master management unit on the first active channel has been established;
in response to a determination that the communication on the first active channel has not been established, attempting to communicate on a second active channel with the master management unit, the second active channel having a frequency different from the first active channel; and
determining if communication with the master management unit on the second active channel has been established.

16. A local management unit, comprising:
-
memory storing software instructions; and a controller coupled to the memory, the controller configured via the software instructions to execute a method comprising; controlling, under supervision by a master management unit, a first solar module of a plurality of solar modules, the master management unit coupled to supervise a plurality of local management units, wherein the plurality of local management units are coupled by a power bus, and each one of the plurality of local management units controls a respective one of the plurality of solar modules, attempting to communicate on a first active channel with the master management unit, determining if communication with the master management unit on the first active channel has been established, in response to a determination that the communication on the first active channel has not been established, attempting to communicate on a second active channel with the master management unit, the second active channel having a frequency different from the first active channel, and determining if communication with the master management unit on the second active channel has been established. - View Dependent Claims (17, 18)

19. A non-transitory computer-readable storage medium for tangibly storing thereon computer readable instructions, the instructions causing a data processing system to perform a method, the method comprising:
-
attempting to communicate, from a first local management unit of a plurality of local management units, on a first active channel with a master management unit, each of the plurality of local management units coupled to control a respective solar module of a plurality of solar modules; determining if communication with the master management unit on the first active channel has been established; in response to a determination that the communication on the first active channel has not been established, attempting to communicate on a second active channel with the master management unit, the second active channel having a frequency different from the first active channel; and determining if communication with the master management unit on the second active channel has been established. - View Dependent Claims (20)
