I am trying to get my electrical system
sorted out on my boat and am totally in the weeds.
I have a Toughbook CF 18 that I want to run as a chart plotter it produces between 26 watts and 40 watts. Other than that all I am running is navigation
, one Interior
light, and a dinky hummingbird depth sounder
. This is a very spartan set up.
I want to get a small solar
panel (somewhere in the 20 watt) range and use the alternator
of a small outboard
, probably anywhere between 6 and 12 amps (haven't bought outboard
yet- whiny thread coming soon). I currently have two Trojan 605s rated at 120 amp hours in the boat but will probably be replacing them with 12 volts.
My dilemma is this: I have filled out West Marine's little "Electrical Budget
Work Sheet" ten times now and it keeps telling me "No". It looks like I would need to run the motor
8 hours a day just to get by. Am I totally screwed here? What else can I do?
