Usually a steel pole in concrete has enough surface area to qualify as a

drill and tap our ground connection into the pole, near the combiner box.
We always put our assumption in our plan notes, based on our

try that system)
Did you tie to the rebar in the foundation or anything else interesting?
125 strikes a year is a lot, do you have a strike counter?

More expensive, harder to find, and harder to cut, but you'll see the
difference in a couple of years for sure. Just a single washer that's
not SS will stand out like a sore thumb later.

Hi Esteemed Wrenchies,
So for the proj

waveform, (no funny spikes, like most portable units) so I can't imagine
why a Sunny Island wouldn't work well with it, but I never actually used
one with a Kohler.

Fellow Wrenchers,
What's folk
re you sure you still need this? I believe 2011 only
requires you bond all the metal to the EGC, as always.

What If you're still over 25 ohms? If you're in lightning country, you
really should sink another electrode anyway.

Ray,
I believe that a pole-mounted or grounded-mo
both the Classic and
apparently the XW can do better than that. Adding losses for converting
DC to AC to DC again, and I can't see any compelling reason to go AC at
the array.

William, the only explanation that I have found for using

plates and begin actual
charging. (just a guess)
I'll actually set the charge amps down, and the voltage up at first,
then when I see it start taking more amps, I set it back to normal
charge parameters.

You might also be able to use pieces of heat shrink on bare Cu just
where it crosses other metals.
This is yet another reason why WEEBs are a god send.

I definitely see cheap surplus PV in the long term future.....

Maybe they did it so people who had modest power requirements could

When they start and shut off in 30 secs, its definitely a control issue,
like the others said. I had one that just needed the radiator topped off
to cure the same problem. That's definitely one of the good ones though;
nothing like it that I know of today.

Today's controllers will pay for themselves in extended battery life alone.
