Hello Wrenches, <br><br>
We have a project with an array on a large metal roof. The AFCI has been
tripping. Investigating the system, there is no evidence of any arcing:
the wiring and connections are all very tight. <br><br>
SMA tech support says it is likely that the nuisance tripping comes from
electrical noise getting picked up by the large metal roof. <br><br>
What has been your overall experience with nuisance tripping of arc fault
protection? What were the suspected causes? What was the
solution?<br><br>
Thanks,<br><br>
Drake <br><br>
