Hello Cruisers Forum! I've been reading this site for a couple years and finally signed up today.
So a little background: My girlfriend and I have been full time liveaboards in New England
for the last 15 months on our Tartan 34, Tumbleweed. We are and will be in a slip w shore power
through the 2015/2016 winter and going to a mooring
ball in the spring of 2016.
So we have a few short, cold, dark months to get our solar
up and running.
We dont think our power demands are that much...
all interior lighting
and nav lights replaced w LED
dometic 110/12v cooler/fridge
for entertainment (We have a 19" flat screen
tv mounted in the boat
but figure that wont be used on the hook)
(2) 12v bilge
(3) 12v usb sockets for charging
phones, cameras, flashlights etc
fixed mount vhf
To be installed spring/summer 2016:
12 volt lewmar windlass
, Monitor windvane
No macerator, head
converted to C-Head composting toilet
acts as water heater
when needed or just heat water on propane stove
so no power consumption
The plan on paper is 300 amp hour house bank with 300 watts of solar
with 40 AMP MPPT
charge controller. (AGM Batterys, not sure if were going 3 12v or 4 6v, we will do the 6v's series/parralel to 12v if they will fit)
will be on its own 25 to 50 watt panel
just a thought, correct me if this is dumb: Windlass battery
mounted forward (near windlass) with its own 25 to 50 watt panel. I thought it would be good to have a much shorter wire run (voltage drop) and given the windlass isnt used daily the panel should keep the battery topped off....
Just a couple of added notes: we are liveaboards now and plan to be cruising fulltime within 18 months. So for 2016 we really just need the solar array and battery banks to be able to run the dometic 50 quart fridge, interior lighting
and charge phones, laptop
and gadgets. we plan to have a 1500 watt inverter
for the rare occasion we need to run 110v. (occasional bag o popcorn in the 700 watt microwave or charge power tools ect). We are not super concerned with the power consumption
of the electronics
as they will only really be used when underway (when nothing else but the refer will be running)
Are we way off course with a system of this size? Too Small
Any other ideas for being self sustained on a mooring
ball not related to solar is more than welcomed as well!
The 18 month countdown to quitting the jobs, selling the cars and heading south starts now!
