Anyone have any experience backing up a Toyotomi oil stove with one of these?
Thanks, Bob-O

A downside might be that the SS screw will corrode into the AL lug and won't
ever unscrew after 9 months or so in the weather unless you put some sort of
anti-seize on it. This tip also applies to S5! clips. I got it from the S5!

A customer of ours has recently suffered lightning damage to 31 out of 160 top
of pole mounted modules. This is the first time in 10 years that I've seen
modules damaged by lightning. Lots of inverter GF fuses and a few inverters,
but never modules. We're trying to determine if it was caused
Thanks Drake and Bob for your comments. Temperature changes have been
accounted for, and the customer is well versed in the proper care and
maintenance and has not changed or removed any acid within the battery.
I am going to continue offline, thanks for everyones feedback

Hello Jeff,
I am curious about the network of ground rods and #6 wire. Can you describe how
the modules and mount are connected to this ground system?
Are there any tight bends anywhere in the #6 wire?
Are any of the poles or mounts connected to other poles/mounts before going to
the ground
Jeff,
Is there any surge protection in the combiner boxes? Any damage visible
in the combiner boxes? Any fuses or breakers open in the combiner boxes?
Is each pole a single string of modules or multiple strings of modules?
While there where undoubtedly ground currents flowing they probably
I've seen it twice. both were DPW pole Mounts. the first time the whole array was involved (this was a few years ago). At the time, we thought it might be a disgruntled employee because no one had ever heard of such damage. I think we used box lugs and star washers on each module back then). the
My 2 cents here is that this is flash irradiance damage.
As there appear to be no burn marks on the module frames right?

No burn marks on the frames, modules or poles.

Hey Larry,
The four poles of ten modules in each row are each a separate string, combined
at a fused DC combiner on the west most pole. A 1 inch PVC conduit runs down
each pole directly to a buried hand hole box at the west pole of each row.
Each conduit contains a #8 EGC along with the
When a long circuit has surge protection at only one end, the voltage at
the unprotected end of the wire will rise, by induction, during a
lightning event that causes the surge protection to activate. There
should be surge protection at both ends of long feeders to reduce
possible damage from
In 2006 we installed a dozen Spire 85W modules w/clear backing in pairs as
skylights. Shortly after, the building attached to the electrical equipment
room, took a direct lightning strike to the wind anemometer 10 feet above
the roof. Of the 12 modules four suffered damage to their diodes. Several
12 matches
