GS-RSD-80-20S is the core device in gate-sea fast shutdown solution, which can be cascgated with a single component to achieve group level fast shutdown function and achieve the purpose of safe and stable operation of photovoltaic power generation system. GS-RSD-80-20S adopts SunSpec special baseband chip with low loss, high efficiency, stability and reliability. It meets NEC2017, NEC2020 and SunSpec certification requirements, and can effectively ensure the safe operation of photovoltaic systems.

After the system is installed, the GS-RSS transmitter will send the "allow to run" signal through the PLC power carrier. After receiving the signal, the shut-off starts the output power supply of the photovoltaic system. In an emergency, just cut off the transmitter power supply or start the external emergency shutdown, it can complete the rapid shutdown of the component, the shutdown device will shut off the photovoltaic system within the time specified in the system agreement, and make the entire string system voltage within 30V. The GS-RSD-80-20S in the off state will output the system indicating power supply at 1V@10mA.

Architecture diagram of GS photovoltaic shutdown system

The input end of the circuit breaker is connected to the photovoltaic panel, and the output end is cascaded to form a photovoltaic string system. The signal coupler of the PLC transmitter is placed in the string bus circuit to send control signals For safety reasons, do not turn on the PLC transmitter during installation.
