1. A solar photovoltaic (“

  • PV”

    ) monitoring system comprising;

    a plurality of solar PV inverters for converting solar power to ac mains power, each solar PV inverter comprising;

    a device monitor for generating monitoring data of said solar PV inverter; and

    a wireless transceiver for (1) transmitting said monitoring data and (2) receiving control data for controlling the solar PV inverter;

    a gateway comprising a wireless transceiver for receiving said monitoring data and for transmitting said control data; and

    a wireless repeater for wirelessly relaying said monitoring data from the plurality of solar PV inverters to the gateway and for wirelessly relaying said control data from the gateway to the plurality of solar PV inverters, the wireless repeater comprising;

    a plurality of antennas, wherein each antenna of said plurality of antennas is positioned to wirelessly exchange data with a subset of solar PV inverters through the first wireless transceivers of the subset of solar PV inverters; and

    an additional antenna that is positioned to wirelessly exchange data with the gateway through the second wireless transceiver of the gateway.
