Generating Device of Grid-connected photovoltaic and ESS with PV panel monitoring

摘要

According to the invention, the development device of system connected solar energy and ess of PV panel can be monitored,A PV panel (10) for producing electric energy and;Accept the current output by the PV panel (10) and output it to the normal current within the registration standard,If the overcurrent is above the standard, the overcurrent cut-off part (20) and output to the first ground wire (30);The first ground wire (30) and the first ground wire (30);The overcurrent blocking unit (20) provides an output current passing through the normal current, which is converted into a current conversion unit (40) within the set current used by the ess (70) and;The current conversion unit (40) receives the converted AC current and converts it into a DC converter (50) for DC current output, andA noise blocking part (60) and a noise blocking part (60) for removing the noise contained in the converted AC current in the DC converter (50);Transmitting the stored ess (70) and through the DC current of the noise blocking unit (60);Providing the current output simultaneously by the ess (70), if the abnormal output current above the registration standard is output to the abnormal output current confirmation unit (80) and the second ground wire (90);Supplying the abnormal current output by the ess (70) to the second ground wire (90) and the ground wire (90) of the stadium;Connected to the first ground wire (30), and the overcurrent value flowing into the first ground wire (30),A PV panel monitoring unit (100) for predicting the life of the PV panel (10) based on the inflow recovery of current and external temperature;Characterized by inclusion.
