<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>This is my first post. I ran into this with
an SB3000 back in June. I called SMA tech support and spoke to Jake, who was
familiar with the problem. His explanation was that there was a series of
boards that got some excess lacquer sprayed on them at the factory. This
lacquer coats the pins, so the jumper doesn’t make a good electrical
connection. Jake recommended removing the jumper and scratching off the outer
layer of the pins with a razor blade before replacing the jumper. I went gently
at first and it worked for a while and then failed again the next time I disconnected
the system. Then I went after the pins with gusto on all four sides, removing
some metal, and the inverter has been working fine since June. I would
recommend having your customers keep an eye out for the “GFDI OPEN”
disturbance if you’ve only fiddled with the jumper, since that connection
would probably be fairly susceptible to failure, assuming the problem is with
the lacquer coating. <o:p></o:p></span></font></p>

We’ve seen this on 2 SMA SB’s (one a 3000; can’t recall the
other) this year. In both cases we got it to work by fiddling with the jumper.
Another installer recommended that trick.<br>

message on a few SB3000US units. I have managed to get the unit to boot
properly by switching it off, pulling the GFDI fuse out, slightly crimping the
fuse clips to make them tighter, then putting fuse back in and switching it
on. This may have actually had an affect, or it may have simply been the
restart that did it. In any case it seems like this may be a more common
occurrence than SMA knows. Two units required one restart, one unit took three
before it finally booted correctly.<br>
