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.

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

called in by another peer to debug that infamous SMA error 8206 on a 2 year

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
SMA users manual. Thanks, Christopher

Interestingly, the problems I've had

disable it?

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.

Subject: [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.... marco
