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 and supports the SunSpec signaling for the rapid shutdown.
The Transmitter-PLC includes one or two cores and an optional power supply: 85-264VAC for residential,180-550VAC for commercial.
