It is quite ironic that just a week after I posted a question to the group
on testing the integrity of lightning arrestors, I had one apparently faulty
out of the box. 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?
