Some notes on the above diagram;
- I'd like to use two Trojan T105 6V in series, 250 amp hours. They might not fit anyway in which case I can go with a single or dual/parallel group 27 Interstate Marine Deep Cycle. I'm putting them into the more aft compartment under the V-Berth on a custom tray. Like others I'm trying to move some weight forward and this will be significant.
- The logic behind using one 4 gang panel with breakers and then a 6 gang panel with fuses; simple, smaller is cheaper. All of the lighting will be LED so it will pull minimal amps. They will all share the same breaker but I need to be able to switch the anchor, steaming, and foredeck lights. Most components like the auto-pilot, GPS, and VHF will come directly off the breaker circuit. The various lights and anything else needing to be switched will go to the 6 gang panel.
- I'm not sure the alternator connection from Outboard should connect at the cutoff switch, but for now that is the way I have it shown. Like the Solar Panel it may need to run straight into the battery. Ideally I will find an MPTT controller that has a connection specifically for that reason.
- I found the Dual Bus Bar fairly cheap on e-bay. I like the plastic cover, even though the bus bar will be protected behind the panel.
- Almost all of the components are Blue Sea Systems, I found good prices online for most of it and I think sticking to one quality brand is a good practice. If there are equal quality but cheaper components out there I would be willing to do more shopping since I haven't purchased anything just yet.
- I'll be making the panel board and its hinge first because that is key to finishing the interior, then probably buying the components as I need to install them. I won't wire up anything too soon and the last thing I will buy will probably be the batteries followed by the Solar stuff.
- I will incorporate an AC charger into this, probably a simple Battery Tender that can be plugged in while dockside or on the trailer, and on extended trips I will have the Honda eu2000i along for the ride.
