I recently added a 15 solix to the console. I ran tinned marine rated 10 AWG from the cranking battery to a bus block under the console with a 25 amp fuse inline at the battery. From the bus block I ran more 10 AWG to the bow where I have 2 Helix 9s spliced in to the 10 AWG. I have a fuse holder behind each unit as well as.
Two of the units are flush mount and I cant disconnect the units from the power. I am wondering if I need to add a quick disconnect at the battery for when I charge the batteries? I also thought about removing the fuse at the battery and just adding a 30 amp breaker that I could flip on and off.
What are others doing for this?
