The requirement for remote shutdown capabilities in photovoltaic (PV) systems is primarily related to safety, grid stability, and regulatory compliance. This requirement aims to ensure that solar power installations can be remotely controlled or shut down in case of emergencies, maintenance needs, or grid stability issues.
With the increased number of solar installations, importance of system monitoring and safety rises. In this trend, wired communications play a key role. Safety standards like SunSpec® Rapid Shutdown (RSD) which support NEC 2014, NEC2017 and UL1741 module-level rapid shutdown are built on wired communication interface.
Figure 1 shows typical power line communication options implemented in different solar installations. These installations can be divided into communication on DC lines (red) and communication on AC lines (blue).
GoodWe remote shut down solution requires the combined action of an on-off switch, long-distance communication, and a control mechanism via signals. The on-off switch can be deployed in a remote place, where the operator can turn on or off the switch at a safe distance to control the inverter.
Within the PV system, if the DC side is abnormal, the inverter will display a "DC INTF" alarm when it starts running. If this fault occurs, the inverter will disconnect from the grid disconnection of
Another option to distinguish is communication from solar panels towards the inverters and the communication towards the grid. Communication between an inverter and MLPE is used for
The Inverter Manager and the I/O Box can be installed in the MV Station as an option and can control the output of the inverters. Up to 42 inverterscan be connected to one Inverter Manager. This means
