Second morning I’ve come out to see my P3 doing the red/blue flashing / power off thing. The instruction manual says this condition means input voltage is too high; however, the P12 on the same circuit is not indicating any input voltage spikes (highest voltage is 123V).
What does this mean? There was a storm last night. Does the P3 go into fault mode from a power spike? Again, the P12 operated normally throughout.
