So I am still buying the parts for this, I have an older boat, 1997 Mainship 34 Motor Yacht. It currently had a Kohler 6500 Watt Genny and Twin 454 EFI engines. This year we will be keeping it on my mooring and will only see dock side on certain trips. Generally when I go somewhere we will be on the hook.
Here is my plan, feel free to give your .02 as I am now to LifePo4 setups and battery solar.
Minimum of 2 Solar panels - Either Solarworld 245 or Trina 305 (I have a few dozen left over from my Craigslist hoarding buys) How I want to mount them the Trina would be easier over my Bimini, Solar world on my hardtop (We also use that for storage) As soon as it is a less cold/windy out I will play with this more. MPPT will probably be a 100/50 Victron
Lishen 272AH 4S 12V setup (Have, bought locally from an eBay seller 1/25/21) Will do all the balancing prior to install once I settle on my "fixture"
Victron Multiplus 2000 12v 120v, 160A max input (On order, should see today)
Victron Orion 12/12-18, Have not ordered yet, not stuck on this but does make sense for when traveling at night to have some charging to the house bank.
I plan to essentially splice in my Multiplus in between the Genny and the transfer switch from shore power. I will wire the virtual switch to auto start the genny when the voltage drops to low and the Multiplus can top off the batteries. With what I plan to have for a load, I will have more then enough power for 1 full day on batteries and almost 2 days. Generally most nights will be a single night out for us anyway but again the Genny will auto start or if I know I will be using a lot of power I can hit the Genny switch anyway. I would LOVE to control the Genny with a GX but can't justify the cost right now. I need to isolate my alternators to just my starting bank, and I will have Orion charge my House bank from that.
I have not bought a BMS yet, Daly seems to be the go to? My house bank is on a 50A breaker, Multiplus says max of 160A. I would think anything above 210A will make sure I should never have an issue do to under sizing, that being said a 250A Daly BT unit seems to be my best bet. Please give me input here.
What do you guys think of my plan? Just hoping to have everything be able to work as simple as possible where if the wife goes to the boat without me, no thoughts really need to be made. Fridge will always be switched on so drinks will be kept cool. I have the remote switch for the Victron, I may keep that off while I am not at the boat making it the only switch that needs to be touched to get out 120v, though most everything is 12v.
