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

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

Hi Dave
I just installed a pair of SB7.7-US41 inverters with the JMS-F Sunspec devices.
The onboard software setup specifies that the Secure Power outlet will not work 
with the JMS-F devices.
These are de-activated when the AC power is off, so even if you connected the 
Secure Power outlet there is no signal to turn on the JMS-F switches.

Re: [RE-wrenches] Optics will not accept remote programming

Kienan:

Thanks for your response. All firmware was the latest.

I think I figured it out. I swapped out the Mate3S and the problem appears
to be resolved. The defective Mate was only about 6 months old. No one
knows why or how the Mate3s caused the problem.

Thanks to all who tried to help.

I've seen something similar if there was a firmware mismatch... the mate3s had 
a newer firmware and the inverters had an older firmware. As was stated before, 
make sure that everything has the latest firmware.

Otherwise, I wouldn't know where to go after that.

Cheers,
Kienan

Friends:



I installed a Radian AC coupled system a few months ago.  We are trying to dial 
it in to work with a Blue Planet battery system.



I cannot make any adjustments remotely through Optics.  Once in a while if I 
reset the gateway I can change one setting, but rarely does it succeed.  The 
little wheel turns for a couple of minutes and then I get a failure dialog box.



I was told to power cycle the Mate.  This did not solve the problem.



Has anyone else experienced this?



Thanks for any input.



William
