[RE-wrenches] SMA Rapid Shutdown and Secure Power Supply

[Dave Tedeyan]

Hi All,

The last SMA-41 inverter I commissioned, had the option for SunSpec rapid
shutdown with Secure Power Supply. I just talked to a level one tech who
was not particularly familiar, but told me that with a sunspec rapid
shutdown device like the JMS-F, you can still use the Secure Power Supply
as if there was no rapid shutdown. I had stopped installing the SPS on
rooftop systems, because if losing grid power initiates rapid shutdown,
then you clearly do not have the power to run a SPS. But it sounds like
maybe the inverter has the smarts to wake the solar back up once you flip
the switch to activate the SPS. Can anyone here verify this? Have you done
this, and does it work as expected with no extra hardware needed?

Cheers,
Dave
