For String or Module Level Shutdown, use with SOB Transmitter, MNLSOB-R1-1000
The Midnite Solar SOB is a simple-to-install, low-cost, Rapid Shutdown System solution – designed to comply with NEC 2014 and NEC 2017. The system uses a receiver at the module that wires in, just like an optimizer, and a transmitter that is installed in or near the inverter. The installer does not need to install any other wiring between the transmitter and receiver. The system is fail safe. If the receiver does not sense the signal from the transmitter, it turns off and opens up the circuit.
