My thought here is that nothing will protect the equipment from a direct strike, but a near strike that may induce a significant surge may be absorbed by the LA and protect the equipment. I like the feedback so far. It would not break my heart to stop using them altogether.:-} Kris

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.

The manifest of this was interesting: when the AC LA (LA302R) was connected in parallel on the AC input to a SB3000 inverter, there was 125vac neutral to L1, 125vac neutral to L2, and 1Vac L1 to L2. SMA tech support suggested the LA as the issue and sure enough, it was. Attempting to test good and faulty arrestors with an ohmmeter gave the same result - off scale open. Any thoughts or comments from the group?
