S05

The data acquisition device can collect the environment temperature, total solar radiation and pv component temperature from the photovoltaic inverter. Voltage and current of confluence box of photovoltaic power station; Ac voltage, current, power, power, electricity, and node voltage, current, power, power quality, and photovoltaic phalanx fault, fault inverter input and output, transfinite inverter voltage, frequency, harmonic overrun, island protection signal, this information by the internal processing analysis, storage, and through the inside of the GPRS wireless data transmission module to data center, at the same time can receive signals from data center configuration parameters are modified to product part.
