I did finally get it to clear using taps but it was a lot of tapping. 3
taps after the second restart with blue light blinking did it - or maybe
that was a coincidence - and it just decided to clear then.
Bill - I did try clearing it through the Data Manager M (EnnexOS) but
there didn't appear to be any place to clear it - nor update the
firmware either that I could find.
I was in the process of logging into the machine itself onsite when I
tried the taps - good thing cause I misplaced the installer log-in! Next
step was PUK - yuk!
And the "source" of the arc-fault was not wiring or connectors - it was
I had turned on and off the DC disconnect as I was making sure Neurio
worked - a guick on and off again inadvertently (changed my mind
midstream as to which I wanted) That was enough to trip the arc-fault!
SMA if you are listening - can't you make this a bit easier? Having to
reset passwords by contacting SMA - that's a major on top of all the
arc-fault pain we are feeling!
Thanks all,
Jeff

I've only had the "tapping" method work on SB-22 inverters, not on -40
inverters. You gotta log on to the machine which I think you can only
do onsite. Has anyone ever done a reset of the 8206 from the portal?

Hey Folks,
How do you clear an 8206 from a SB7.7-US? the manual says tap on the
cover within 10 seconds of error message. That's not working.
Does that tap then set it up for the next restart or is it supposed
to clear it right away - I've tried restarting again to no avail.
When I tap right after the message appears it simply toggles to the
next screen.

Hello Wrenches,
You may be aware of this but the -92R firmware supposedly has
addressed the arc fault issue for the US-40 inverters. See here for
the download:
https://www.sma-america.com/service-support/downloads.html It fixed
an arc fault issue for me yesterday at least. Bring a thumb drive,
the update process took about an hour to perform.

Same up here in the southern sierra. I get calls from ABB and a
few from SMA to look at systems that people far away installed
and as a local 3rd party it can save some money. Whatever they
quote me I triple the price. 1/3 up front and the rest when it
is done. ABB is really slow with payment. I think they sold
their inverter business? Sunpower is a great panel but they have
had some bad runs. Probably why there are so many new/used
panels on the secondary market. They are great for Offgrid
ground arrays and no AFD.

Chris,
Sunpower has taken some responsibility on some of our older
Sunpower systems that are arc faulting. We tell them that a
system is arc faulting, and then they insist on sending up a
3rd party contractor to inspect the system and potentially
install what they call "Tigo Diodes". I am still not exactly
sure what that is. It also seems to take them months to send
anyone to upstate NY, as we have a bunch of customers that have
been waiting months for the 3rd party contractor to come take a
look. You likely could only follow this route though if the
system was installed by a Sunpower dealer and you are a
Sunpower dealer yourself. If the original system was from a
Sunpower dealer, you can also have the customer call Sunpower
directly.
Cheers,
Dave
