Re: [RE-wrenches] SMA phantom arc faults

[Matt Partymiller]

If you are using EnnexOS you can clear remotely.  Select the device with
the issue, then config, then parameter.  Filter by 'AFCI'. Turn off. 
Wait a few minutes, turn back on.  I wouldn't recommend doing this
unless you're certain its a false arc-fault.

Re: [RE-wrenches] SMA phantom arc faults

[Dave Tedeyan]

I am fairly certain you cannot reset through the portal, unfortunately. I
have done the "rapid whack method" many times. Feels kind of strange, but
works well. The message must be displayed for that to work though. So if
you already reset the inverter, you have to wait for the error to show up
again.
Cheers,
Dave

Re: [RE-wrenches] SMA phantom arc faults

[Jeff Clearwater]

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

Re: [RE-wrenches] SMA phantom arc faults

Hi Jeff,

Yes, that doesn't seem to work well.  Best way is to log into the machine
and clear it with the browser interface.

Here are my notes from this process because its not inuitive:

Double tap cover
Blue Light Blinks
Find Network Called SMA[Serial Number Here]
Connect to this Wifi network
Open Browser
Plug into address bar 192.168.12.3
Log in as installer
Password is ___(Im not sure)


Select Device Parameters
Push On Edit Parameter button
Device>Operation>Reset Operating Data
You must Save these changes.

This will clear the device and allow it to restart.  I would also verify
that you have the -92R firmware otherwise it may happen again.

Good luck

Re: [RE-wrenches] SMA phantom arc faults

[Jeff Clearwater]

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.

ABB is really slow with payment. I think they sold their inverter

Chris,
Sunpower has taken some responsibility on some of our older

You likely could only follow this route though if the system was

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

 Aloha all,

 My company has really been struggling with the SMA US-40 line of
 inverters and incredibly disruptive to positive customer experiences bogus
 arc faults.

 We were told by our SMA friends that a firmware update/fix was
 forthcoming in mid-August and we've heard nor received nothing last month.

 Does anyone know anything as to where they're at on this?

 Really frustrated

Re: [RE-wrenches] SMA phantom arc faults

[Dave Tedeyan]

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.

Re: [RE-wrenches] SMA phantom arc faults

Got called in by another peer to debug that infamous SMA error 8206 on a 2
year old 5kw unit.  The array is roof mounted on composite shingles with 14
SunPower 345w modules. First time ever seeing this error on this project.
I'd love to hear from others as to what they've found or better yet hear
from an SMA rep as to what they suggest. Not a whole lot of detail in the

Re: [RE-wrenches] SMA phantom arc faults

[Dave Tedeyan]

Hi All,
I have noted that the phantom arc faults occur with high power modules such
as Sunpower. I have also heard of many issues with Tigo optimizers.
One potential easy fix is to disable the Optitrac Global Peak. This seems
to work to get rid of the arc faults in both the -22 and the -40 inverters.
The only downside to that will be reduced power output in partial shading
conditions.

I wouldn't hold my breath for SMA's firmware fix. I was told last year it
would be out by this February (7 months ago) and that they would
automatically push the firmware fix to all their inverters...

Cheers,
Dave

Wrenches
I have had chiller pump contactor along with wells, shop air compressors
all create enough of an arc to trigger the inverters. ABB inverters only
pick up off the DC but even there l had arc welders trip the inverters.

Re: [RE-wrenches] SMA phantom arc faults

[frenergy]

Interestingly, the problems I've had with the SMA -40 AFCI faults have 
been on Comp roofs.  When I've gone "inside" a -40 with my laptop, I'm 
pretty sure I've seen where you can disable it?

Metal roofing can apparently be affected by radio waves and by other 
factors that create a disturbance that can trigger the AFCI.The TL 40 
was supposed to overcome this problem.

[RE-wrenches] SMA phantom arc faults


Aloha all,

My company has really been struggling with the SMA US-40 line of
inverters and incredibly disruptive to positive customer
experiences bogus arc faults.

We were told by our SMA friends that a firmware update/fix was
forthcoming in mid-August and we’ve heard nor received nothing
last month.

Does anyone know anything as to where they’re at on this?

Really frustrated

At least with the TL-22s, the AFCI function can be turned off. You
need a_ Web connect speed wire module_. .I don't know if this same
protocol will work for the TL 40s or not.  

Metal roofing can apparently be affected by radio waves and by other
factors that create a disturbance that can trigger the AFCI.The TL 40
was supposed to overcome this problem.

Re: [RE-wrenches] SMA phantom arc faults

[frenergy]

Hey Marco,

            I hear you, we have installed many SMA-40's and we're not 
at the same point as you may be but we've definitely had a fair number 
of arc fault shut-downs which take a site visit to rectify.  One 
location had been experiencing lightening over a year and a half which 
seemed to be triggering the 8206 code.


            I had to go back three times to one such install. After 
that I went back with my array map (before an install I make a laminated 
map of the strings with home-run locations) and started inspecting 
home-run connections.  I was lucky and found the culprit with my first 
try.  Somehow I hadn't pushed the wire end which I had crimped on the 
tip to far enough into the plastic connectortoo cold maybe? lazy? 
distracted?...not sure but there it was, my bad.  I took that connector 
back to the shop and sure enough it would show intermittent connection 
with an ohm meter, perfect for an arc fault.


            This doesn't answer your question about the fix but thought 
I'd apply a little egg to my face in the hopes of saving others the same.
