I agree about the 30amp cut-out being a problem. Now, this Duo Charge has worked on this boat for a lot of years with this being the first problem. So it really has worked pretty well.

I have no idea how electrical stuff works. I think that the 30 amp charging limit is fine, but I wish it was designed so that it still supply that 30 amps even if the battery bank wanted more. As it is, a Duo Charge will not charge up my thruster bank since it will ask for too many amps.

So, since I have a spare ACR and I have some spare 4/0 cables, I think I can pretty easily reconfigure the system to use an ACR.
