Hi Mohammad and Aty
Thank you for the drawing which helped me a lot. Exactly this page was not in my documentation. Don’t know why?
I found in the 220V Panel drawing K1- and K2-source referenced, but without any detail about K1 and K2. Now everything is very clear and you are absolutely right with the priorities.
This sound a bit complicated but it’s finally the priority GEN, Sore, Inverter as you said.
BTW: What is your Lithium Project doing? You have changed KOKOMO to Lithium meanwhile?
Thanks and fair winds

There are electrical schematics in the original AMEL operator’s manual in the Appendix section, that came with the yacht, that show how they are wired. Attached is the schematic for the K1-K2 switchover relays.
I believe K1 and K2 switch/relays make the selection of power source. Power first goes through K1 which selects the source between shore power and generator. I believe that generator has priority over shore power. Once this source is selected, it goes through K2, which selects between the output of K1 and the inverter, with the output of K1 having higher priority.
I am fairly certain that the priority is:

Subject: [AmelYachtOwners] Shore - Generator Switch-over box on A54 #solution
I tried to find out how the Shore/Generator Switchover Box in the Engine room of my Amel-54 is exactly working. I do have in addition a 2500W MV inverter installed originally from AMEL. Last few weeks the Switch-over is doing strange things and fuses are blowing.
I have not found any accurate information (drawings) electric scheme of that AMEL specific switch-over mechanism. I don’t know how it detects either one or all 3 of the 240V sources, and which is the master over-ruling the Generator or Shore and/or Inverter. How it protects the Inverter when Shore or Generator is running, etc…
Thanks a lot for investigation and best regards
