POWER SUPPLY SYSTEM AND POWER MONITORING DEVICE

A power supply system includes a plurality of solar power generation device groups, a power monitoring device group, and a power transforming device. The power monitoring device group includes a plurality of power monitoring devices, and each of the power monitoring devices includes a processing module, a serial control module, and a power detecting module. At least one power parameter detected by the power detecting module of each of the power monitoring devices is provided to the processing module. The processing module transmits the at least one power parameter to a control system through the serial control module.
