I have question related to neutral wiring using 2 inverters AND bypass switches for each of the inverters. My inverter wiring diagram is straight forward, L1/L2 + neutral in from grid panel, and L1/L2+neutral out to load panel(for each inverter). But when I add the bypass, would I be running 4 neutrals to the load panel with the 2 additional neutrals coming from the grid panel? (logically doesn't make sense to me) I've attached a picture of where my head is at.
Can any of the neutrals be shared with busbars? (IE, running all the inverter out neutrals to 1 busbar, then 1 wire to the load panel? (since everything will be joined together already in the neutral busbar in the load panel). I guess I'm asking if I can optimize the wiring of the neutral wires and a second question of the right electrical flow from the load panel. (a post from @Hedges regarding Auto-transformer L1/N/L2 current had my head swimming)
Thanks!

But he also said in a different post (with diff question) " I don't think it is necessary to switch neutral.
Neutral should follow path and be in same conduit as L1/L2 where current is flowing. I would even make a loop out of N if necessary to achieve that, but having multiple circuits enter and exit through same conduit could avoid that, and having all three circuits enter the switch through a single branch would mean N doesn't even need to go through it. (Similar to a light switch, just gets hot and switched, not neutral.)"
Thanks!
