[RE-wrenches] Sunpower micros and mysterious outages

[August Goers]

Strange one. I would be surprised if the PV system has anything to do with
this. We’ve experienced strange electrical intermittent problems and they
have almost always been related to grounding or neutral problems. I realize
that two different electricians have checked out the site, but maybe they
missed something like a loose neutral (check all the way back to the
service point of connection). It might be worth calling the utility out as
well incase their feed has problems.

Friends of mine got a Sunpower system installed last year. Ever since then
they have had intermittent problems with circuits in their house going dead.

The array is 14 each Sunpower SPR E20 327 C AC. The array is mounted on a
corrugated steel roof on their garage, about 20 feet from the house.

What happens is that a circuit in their house will either go dead or brown
out so lights barely glow. This happens to various circuits and at any time
of day or night. The rest of the circuits will work fine and the event will
last an hour or two. The breakers don't trip. They have had two different
electricians there to check the house wiring and it's all solid.

Any ideas? Some kind of metal roof capacitance?

Many thanks,

Hilton
