When I am on shore power and the Air Condition compressor kicks on the Quattro makes a buzz sound for about 2 seconds. Is this normal? Shouldn't the power just pass through while on AC1? It doesn't look like it's trying to invert when it happens.

Quattro Buzz Sound on A/C compressor load?
I found the problem. Power Assist was enabled. When this is enabled then you hear a surge even if the Quattro has enough power from a 50amp service. Not sure if this is oversight on the Quattro or if this is just the nature of the beast. The fix is to disable power assist. I don't believe we will need this feature anyways since I stay on top of how much power we consume and adjust when need be.
