Don't rule out the post!
I had a similar problem with the post's neutral wire. The post would work most of the day until late the afternoon when the suppertime crowd began consuming power. In my case I only had a surge protector. All of a sudden, the power would begin pulsating. The ATS would be clicking loudly, lights flickering, microwave flashing, co2 alarm chirping, a plug-in voltmeter needle swinging. In the end before maintenance figured it out and fixed a bad burnt connection in the post it destroyed the ATS, converter and inverter.
I would follow the suggestions above first. Especially the ATS connections.
