Don't forget lightning protection

Lightning protection is important.

LIGHTNING HIT MY HOUSE..... - YouTube

That's happened to me once. I cringe everytime a thunderstorm comes around..

About 15 years ago, there was a line of five 30 foot evergreen trees across the street.
One of them in the middle got hit. All of them died within a couple of years.
When it happened, I was down in the basement checking for flooding.
There were arcs flashing around the room, as some of the power drained off to the swamp behind us.
Loud snapping sounds scared the heck out of me. But we only lost our new 9600 baud modem..
Across the street, they lost their GDO. The PCB was half melted.

My building is long. (Roughly 50') I had earth grounding on both ends via 8' ground rods, connected together with wiring from end to end. Everytime lightning would strike anywhere close to me, I would hear the snap-crackle-pop noises coming from who knows where. Lost a cordless phone, charge controller, a 400 watt inverter and a few other items over the years..

I changed my grounding scheme to a single point system. Removed the two grounds from the ends and installed an earth grounding point in the center with one rod and reconnected to my existing ground wiring throughout the building. Snap-crackle-pop disappeared and I haven't lost a thing since..

In the past, I had a hardline phone connection. I installed ~2200' of buried wire to the nearest pole. Had all kinds of issues while that was in! Went wireless, disconnected the hardline and a bunch of my issues went away.

I have no public utilities connected to my place today. It's nice..

That sounds like your connection from point-to-point might have had a bit of inductance.
Because of the fast rise time of lighting current, inductive reactance (Xl)
Electrical reactance - Wikipedia, the free encyclopedia
can make the drain path so resistive, the current takes an alternate path. (snapping & popping).

Sometimes Hams make the mistake of adding rain loops to protection wire.
Any loop or even a sharp turn in the wire will boost the Xl.

IMHO, A good single point ground, fed by low Xl drain lines is a good system.

That's what I have at my house. But, the weak points are still there.
Grid power lines, city water (1/2" copper), and a separate set of grounds
out back on the PV arrays.
The grounds on the PV feeds are pretty good (into the water table),
but the ends of the feeds coming into the house are floating above ground.
Hopefully, if the PV takes a hit, the PV DC feed lines won't bring in any large fireballs.

Now that I have optical fiber (Fios) coming into my house, I wish the old copper phone line was gone.
Those things are lightning magnets. I could disconnect my end from the house,
but the bitter end on the pole would be hanging there for years, before they cut it down.

I've got everything grounded except the panels in the sky. Guess it's time to get that grounding wire up.
