[RE-wrenches] Delta LAs

[August Goers]

All -

I guess my thought is a little off topic, but are lightning arrestors even
worth using at all? My logic has always been that if lightning does indeed
strike that it's likely going to blow the arrestor and and inverter. We
don't have much of a lightning issue issue in the Bay Area so I don't have
any direct experience.

Best,

August
