Current panel has 4 AC sources (2 Shore/2 Gensets) for each section (120 I, 120 II, 240 I, 240 II) with a selector switch for each section (see image). This provides the ability to map any AC source to any of the 4 panel sections. I'm wiring in 2 2x120 3k Quattro's in Parallel. I'm looking for an appropriate solution to manually bypass the Quattro's (to use existing panel setup as-is). My thought was to interrupt the output of the 4xAC switches (output of selector switches for each section) to either toggle the inverter "in circuit" or out.
I assume someone with a larger boat has already done this. Did you use a rotary switch (12p? L1, N, L2 x4) or contactor?
