[RE-wrenches] Delta LAs

[August Goers]

Jay -

I can see that point, but does that really effect insurance payout? It seems
like one could argue that a properly installed system with proper grounding
inspected by a building official has a lot more clout than and little grey
cylinder next to the inverter or disconnect.

Please all wrenches, correct me if I'm wrong but I can't remember a single
time when there was a post about an actual lightning strike and a lightning
arrestor actually doing its job - meaning that an arrestor took a hit and
protected the array and or inverter. I've heard plenty of stories about
blown lightning arrestors and good equipment but no one seems to know what
caused the situation. It might be that lightning is hard to track and I
agree with that. And lightning might have been the cause. It would be great
to track lightning-fried installations to see what happened and what could
be fixed. If lightning arrestors are the solution then by all means we
should install them. Most of the time I think that proper grounding is the
solution although I wish that field experience would prove the point.

What do you think?
