There is circuitry in the converter that will disconnect the battery from the camper when the battery is bad/dead/shorted to prevent the converter from exploding the battery when trying to charge it.
Perhaps the strike spike confused the circuitry enough to cut the battery off from the camper.
Say, has anyone mentioned to you the need for a good surge suppressor?
All the recent posts about a surge suppressor went through my mind at that very moment. It is on the list, funds pending.
The battery was still online as it continued to drive the lights etc when I shut the power down. We ran off battery for 20+ minutes while waiting for the storm to blow over. This makes the most sense to me, that a lack of power continuity (surge or brown whichever way it went) caused the propane alarm to sound off.
Battery is less than a year old, as is the trailer.
