Wrenches,
A "maybe customer" sent me this link to a Google video about his Grandpa's
homegrown PV system. It takes a very different approach than the industry
has gone. Apparently it works, although it lends itself far more to educated
homebrew than to something a company would do for a customer. He told me his
grandpa was an electrical engineer. It's a funky homemade video but
entertaining. The first 45 seconds can be skipped as it's about beer
preference.

24 golf cart batteries in a 12v system, with two diodes per string to
prevent uneven charging and discharging;
What appears to be about 2700 watts of PV, plus two unknown wind gennies.

After first viewing the video I sent back this response:
I saw the video - very nice. Your gramps has created his own unique approach
and has done a very good job. This is the way off grid PV was done twenty
and more years ago, although few back then had the level of knowledge and
sophistication he has. The industry has gone in very different directions;
indeed, he couldn't do what he has done for someone else's home if he needed
it to be inspected. Unless you object, I'd like to share the link to the
video with other installers nationally; I'd be interested in their responses
on seeing such a contrarian approach.

There was no objection to sharing in the reply, but please treat it with
respect.
Enjoy!
