Hi Nate,
Your wiring diagrams are showing a connection from an Input of Lynx Distributor to the Inverter/Charger... Is that correct?
Instead, I'd expect the Inverter/Charger to be connected to the Battery (Output) terminal of the Lynx Distributor.
Thanks for all of the helpful information you're providing.
Leo.

I just noticed that your 30A OEM RV Solar Retrofit Wiring Diagram is the only version that omits a master disconnect, is there a specific reason for this? Any issue with adding one to that particular layout?

Nate, Which wiring diagram would best fit my equipment listed below? I have it all connected and everything appears to be working fine. I had an electrician friend come to check things out before we turned it on. I'm getting into your videos, fixing some things like my disconnect switch and I want to keep learning and be sure it is done right. My main confusion is the existing transfer switch and how I change the wiring there and get it to the Multi-plus inverter/charger. Do I need to add an additional transfer switch? Now when I am on shore power, I have to turn the inverter/charger on to get 120v.
