Heh, similar issue once, only no battery backup and the main breaker would trip instantly. So, we had power, but it wasn't coming back up. After an expensive discovery that the issue wasn't on our side, the power company had to get into the junction box and discover that the wire had melted to the metal. We were 'this close' to losing everything due to a fire. Especially because once the metal cooled down enough, the power could come back on for a few hours.
