Lightning Protection

When there was an attempt to add those types of devices to NFPA 780 they were rejected for lack of any technical substantiation that they actually work. The only UL certification for their products is for use as a standard lighting air terminal that is used in a conventional lighting protection system.

Can anyone here talk about lightning protection of a Tesla system?

If power line transients are destroying equipment, I'd consider industrial SPD that resets after each event.

Living near tall power lines may give Zeus & Poseidon something else to aim at, but your electrode system may be absorbing too much.

Thanks for replying. Power line transients are not the problem...we're on the Tesla battery most of the time. It's nearby lightning strikes that are frying our battery, plus assorted wifi gear, router, tv, control of electric gate, etc. I don't know how this lightning is entering our electric system since it's disconnected from the grid unless needed, we've never had a direct strike on the house, just nearby, perhaps 30' away, but a huge one. I installed a lightning strike protector that looks like a clear glass bulb with blue LED's to let you know it's connected, and says it will clamp any jolt up to 100,000v, so we'll see. It's connected across the 220 lines to the house, whichever feed it's getting, Tesla or the grid. I'll go fish out the name and model and put it up here for you to see.

Close proximity lighting strikes are natural sources of EMP known to destroy un-shielded electronics or wiring.

Surge protection wont stop EMP. You need taller decoys placed further away, like metal-frame windmills with some deep electrodes. None metallic structures burn or blow up when struck by lighting.

Lightning is primarily attracted to tall, pointy, and isolated objects. While materials that conduct electricity, like metal, do not attract lightning more than other materials, they can provide a path for lightning to follow if struck.

I tend to agree with the EMP explanation. There could have been induced power under ground via the main entrance cables to our house which are bured and I dont' think shielded. I don't think windmills are on tht table. We live in a semi-rural mountainous area and I think the neighbors would throw us out if we constructed one. THere was just recently a neighborhood demonstration agains a new CELL tower going, which we certainly needed. We are surrounded by tall palms, which are also said to be natural attractors of lightning, and at least two were struck and died. My solution to this the next time we have a lightning storm in our area, I will just shut down the Tesla and disconnect all grid feeds to it.

Thanks to all of you folks who contributed.
