MidNite Solar MNLSOB-R1-600, rapid shutdown Shut-Off-Box receiver, 600 VDC strings

The MidNite Solar MNLSOB-R1-600 is a low-cost & easy to install rapid-shutdown solution. It is one-half of the system; the unit works in combination with the MNLSOB-T1-600. The latter transmits a signal on the wiring coming from the PV modules, and the MNLSOB-R1-600 looks for that signal to be present. When the signal goes away, the MNLSOB-R1-600 disconnects the DC Voltage coming from the solar panel string. The unit complies with both the 2014 and 2017 NEC code regarding rapid-shutdown.

One receiver per PV string is required, and a single transmitter. The unit installs just like an optimizer, onto the rail under the last panel of the string. Power is provided by the panel, and no additional wiring is needed. Up to 6 strings can be used with a single transmitter.

At this time the MNLSOB is meant for grid-tie systems. Many off-grid charge controllers put too much noise on the PV wiring to work with this solution (though Magnum’s PT-100 is confirmed to work OK).
