A device, system, and method for communicating with a power inverter of an array of inverters includes transmitting a relay message from an inverter array controller to a relay inverter in response to failing to receive a response from at least one power inverter of the array. The relay inverter is configured to retransmit a message from the inverter array controller to a non-responsive power inverter of the array of inverters in response to receiving the relay message. The relay inverter may subsequently retransmit a reply received from the non-responsive power inverter to the inverter array controller or to another power inverter of the array of inverters.
