Multiplus-ii 12/3000/120 pulsing sound

VRM screenshot.pngI am running a new MP-ii, Cerbo GX, Color Touch 70, SmartShunt.

1. Question (1) is regarding what sounds like a pulsing (whomp, whomp, whomp) from the MP-ii. While it's doing this, all the lights have a noticeable flicker in unison w/ the "whomp". If I place my hand on the MP-ii I can also feel the whomp vibration coming through. It's not the sound of a relay "clicking" but a very low sound (kind of sounds like bass from a speaker). The sound seems to happen (I think) when it's going from pass through to inverting. Almost like it's deciding what it wants to do. :) Again, no transfer switch "click sound" can be heard while this is happening.


2. Question (2) I noticed in the VRM portal that it's showing L2 on both the shore/AC loads. Did Imiss a setting somewhere to disable that? I am using 50a 120v 60htz from shore/gen AC sources.

Does this occur when its only inverting or when the generator is running - a diagram of the setup would help - and also what Firware are all the items currently on
