Dave et al., Please note that SMA no longer offers the TS4-R-F devices—according to our distributor, they ceased offering them toward the end of last year.
SMA maintains a list of compatible rapid shutdown receivers here <https://files.sma.de/downloads/SunSpec-Kompatibilitaet-TI-en-12.pdf?_ga=2.194448045.104408375.1630023285-229768817.1630022978>. You will see the JMS-F device listed, along with the APsmart device that Jeremy recently wrote about <https://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/msg29719.html>. The TS4-R-F device is also listed, but, again, I believe it is no longer being manufactured/distributed. -- Corey Shalanski Jah Light Solar Portland, Jamaica On Wed, Aug 25, 2021 at 9:02 AM Dave Tedeyan <d...@sungineersolar.com > wrote: > Hi Chris, > I also am curious of others experiences.
