In various embodiments, a process for configuring or commissioning a solar power system includes receiving, at a controller, hardware identifiers of a plurality of power electronics modules to be configured. Each of the plurality of power electronics modules of at least a portion of the plurality of power electronics modules is associated with a corresponding photovoltaic panel. A hub is configured to wirelessly communicate with the plurality of power electronics modules. The controller is physically connected to the hub and communicates with the hub via wiring that also carries power from photovoltaic panels to an inverter. The process includes configuring, by the controller, the plurality of power electronics modules using the received hardware identifiers.
