Jim, I believe the only way to "protect" electronics is to unplug them from both the antennae and the panel. That will prevent a strike from being directed through the units. That said, in the event of a direct hit, the amount of electricity in the immediate vicinity of the unit may still cook the boards......
We had quite a show up this way as well from 0315 til about 0400. Never seen so much lightning so close for that period of time. We also lost power for an hour.
