Module Micro Controller (Shutdown Function Series)

R Series

The R Series modular micro controller has a module level quick shutdown function, and different product models can be selected according to system design needs, such as "one to one" or "one to two". Provide effective solutions for fire safety, meeting the photovoltaic safety requirements of US NEC 690.12-2014, 2017, and 2020. When the system encounters an emergency situation, the micro controller will switch to safe mode and automatically disconnect the output of each module to ensure system safety; Users can also trigger the micro controller to switch to safe mode through communication with the brake operation or emergency stop button. The PLC communication method does not require additional wiring and avoids wireless instability, keeping the system in an efficient and stable state. At the same time, it has many advantages such as simple and convenient installation, safe and reliable use, and can be matched with most third-party brand string inverters.
