The APsmart Rapid Shutdown System Transmitter-PLC is part of a rapid shutdown solution when paired with APsmart RSD-S-PLC, a PV module rapid shutdown unit. While powered on, the Transmitter-PLC sends a signal to the RSD-S-PLC units to keep their PV modules connected and supply energy.
RSD-S-PLC units automatically enter rapid shutdown mode when the Transmitter PLC is switched off and resume energy production when power is restored to the Transmitter-PLC. This solution complies with NEC690.12 specifications for 2017&2020 and supports the SunSpec signaling for the rapid shutdown.
Transmitter-PLC Outdoor Kit includes a Transmitter-PLC with one or two cores, outdoor enclosure, 85-264VACor180-550VAC power supply. It could be used in residential or commercial projects.
