Thanks for all of the responses on this guys. I looked around and found these units from Solar BOS.

As far as I have been told, they DO use a powerline carrier communications method to trigger the MLPE units. A trigger device has to be wired to AC to detect loss of grid, and one conductor of every PV string must go through their attached CT donut which imposes this communications onto the PV wiring, and communicating with the module level components. >From their documentation: TS4-F units automatically enter rapid shutdown mode when the RSS Transmitter is switched off and resume energy production when power is restored to the RSS Transmitter. This solution complies with NEC 2014 & 2017 690.12 specifications utilizing power-line communication (PLC). Please tell me what system you have that is wireless? Thanks, Glenn From: RE-wrenches <[email protected]> On Behalf Of Darryl Thayer Sent: Thursday, May 30, 2019 12:16 AM To: RE-wrenches <[email protected]> Subject: Re: [RE-wrenches] rapid shutdown units for obscure inverter Try Tigo, they have a MLPE shutdown wireless and does not use PLC (Power Line Communication). With an unknown inverter, the inverter switching noise may trigger the Tigo's PLC to keep on or shut off. Shutting off the inverter stoping module array current, and the AC supply to the "Gateways" loss of the heartbeat signal causes the shutdown of the modules. I have used such an arrangement and it is passing every test. This was maybe 1 or two years ago. Tigo may have made changes since then. hope this helps.

The plans specify 5 Ginlong Solis inverters. Ginlong does not make their own rapid shutdown device, so units by Innovative Solar Products have been specified. The Innovative Solar rapid shutdowns are made to order and will take 4 weeks (not good for us). Does anyone know another mfr that makes rapid shutdown devices that are compatible with other mfrs inverters?
