Folks - planning a system for a 40' aft cabin live aboard.
Goal is to have all my systems available for 5-7 days - minus AC, oven, and Hot Water heater
I've done the calc's for usage so the solar panels (3 @ 370w) and batteries will/should be sufficient, but could change out the inverter bank for lithium in the future if needed.
Please take a look.
My pref is one isolated system to feed the whole boat with only 2 connections (inverter to vessel ground and inverter to a 110v switch)
- keeps 4 banks charged
- keeps components/$ down
- keeps system separated from current house set-up for easier install (only need to run AC current marine wire to a switch)
- downside loose some efficiency from going/charging DC to 110 to DC
- leaning towards the 3000w inverter bank being 24v (based on inverter size and get lower MPPT amps)
- I do not always need to have the Battery Charger on (can turn off at the panel and leave on for several hours mid day as needed)
2nd page is more tritonal set-up with a system for each bank.
- more components
- more wiring to run (some of it heavy gauge battery wire)
- less clean set-up (inverter system stays the same so 3 installs vs 1 basically)
Comments please?
