1. A method for establishing communication between a controller and a plurality of inverters, the inverters configured to convert direct current (DC) power from an alternative energy source to AC power, the method comprising:

  • receiving with an inverter of the plurality of inverters a response request transmitted by the controller via an AC line, the response request including a length of a response time window;

    determining a random response time for the inverter based on the length of the response time window;

    transmitting a response to the controller at the response time, the response including an identification of the inverter;

    andin response to receiving an acknowledgement from the controller in response to the transmitted response, updating the inverter'"'"'s operation to ignore subsequent response requests from the controller.
