Which will not be true in a nearby or direct lightning strike. It’ll depend on your ground points, their characteristics, the soil between them, and a bunch of other factors. All you can do is the best you can do and hope it’s good enough. The towers atop Mount Washington, which is very rocky at...

Umm, doesn’t the grounding-the-battery-negative discussion depend on the details of the inverter? Yes, you should ground the battery case, but should you always ground DC-minus?

Well, that’s not scary or anything!

My grid is only about 80KM in maximum dimension, but it’s unreliable and dirty enough that I can’t wait to commission my batteries and get completely off-grid.

What’s that?

If you have 1:1 net metering you have a virtual battery at 100% efficiency, infinite size, and zero cost. What was the question again? Now you know why the power companies don’t like it.

Or having tax rebates for the above. 🤷‍♂️ None of this stuff has a single solution, and everything’s chaotic enough that the unintended consequences push the results even further from what the originators (said they) wanted. We’re going to have tariffs and rebates and incentives and job...
