Re: [RE-wrenches] Panels Damage in Delivery
IMHO.. Cheeped out home made (supplier) built pallets w/ stacks over
6-8 panels.. almost guaranteed problems.. I've had to refuse several
shipments in a row.. Fairly easy to spot tho.. Usually 1/2" OSB / 2x4
stud frame, no bottom boards... bent bottom panel frames, shifted/
loose loads... I have pics someplace.

Dear All,
I am learning for the first time, and the hard way, the necessity of
checking deliveries for damaged panels. For the first time I am
hearing that it is not uncommon for the bottom or last panel to be
damaged in shipping. Nobody ever explicitly tells you this until it is
too late. It is ridiculous to think folks are going to physically
unload a pallet of panels just to make sure the bottom panel is not
damaged. And yet... We are now without recourse as the bottom panel
was not discovered until a month after delivery and we are now in
desperate need of a Solar World 325. Unicorns, attractive naked people
and Obamas to anyone who has one.
Probably best to contact me off list.

Re: [RE-wrenches] AFCI problems with SMA RSB
Wrenches We have sites with multible Tri-powers and sometimes we get an arc fault, lately its been right at 2:00 pm which happens to be right when the bell sounds. We are testing a line filter that shluld supress outside noise. If anyone is intetested contact me off libe and l will get you the info, FYI its just over 200.

Re: [RE-wrenches] AFCI problems with SMA RSB
Was it raining on the days you got the error? We had that problem on a system during low light (beginning or end of a day) on days when it was raining (although I think it was actually an arc fault message). It was unrelated to an RSB (didn't exist yet). There is a thread about it here somewhere I could try and dig up...

[RE-wrenches] AFCI problems with SMA RSB
Hi All, I’m wondering if anyone else is having trouble with the SMA Rapid Shutdown Box. We have an installation where an SMA 7700TL-US-22 (rebranded as SunPower) is fed by an array with a Rapid Shutdown Box. Many, but not all, mornings, the inverter would fail the AFCI self-test on wakeup. When reset, it would operate fine all day. There was never an actual indication of an arc fault, just the self-test failure. SunPower, in consultation with SMA, decided to replace the inverter. Everything worked normally for a couple of weeks, then the problem resumed. Again, no arc-fault indication, just the self-test failure and then full operation the rest of the day after resetting. We began to suspect the Rapid Shutdown Box, so we bypassed it completely, and there were absolutely no problems for several weeks. SMA was then willing to replace the RSB, after which everything worked fine for about a week, then this morning the same issue. Again, self-test failure, then when reset, it has to go through another self-test, which it always passes and then runs all day. Has anyone had problems with the RSB, or, with AFCI in general? Based on this experience, this is the second and last RSB we’ve used, and have somewhat reluctantly gone to all micro inverters to meet rapid shutdown.
