A solar photovoltaic monitoring system for monitoring and controlling a solar photovoltaic inverter is provided. The system includes a wireless transceiver coupled to a solar photovoltaic inverter that includes a device monitor for monitoring and controlling the inverter. The device monitor generates monitoring data defining a status of the system and transmits the data by using the transceiver coupled to the inverter. The system also includes a wireless repeater for receiving data from the inverter and retransmitting the data and a transceiver coupled to a gateway capable of communicating the received retransmitted data to a monitoring station. The gateway also transmits control data received from the monitoring station. The repeater receives control data from the gateway and retransmits data to the inverter. The inverter receives the retransmitted control data and controls its operation based on the received data.
