4.Monitoring
4.1 Overview
The inverter has a variety of communication methods. When users need to monitor the operation
information of the PV power generation system, we provide the communication system solutions shown in
Figures.
Fig 4-1 RS485 (standard MODBUS protocol) communication system mode
Grid-connected PV inverters can communicate with RS485 bus(standard MODBUS protocol) so as to
monitor the working status of the inverters in real time.
Figure 4-2 WIFI/GPRS communication system mode
After installing the GPRS or Wi-Fi data collector module, you can monitor the operation of the PV system
through the AUSTA App program “Ausat Solar”.
