Eric-
Thanks for the input. I do not want to carry 500 lbs of AGM batteries,
and the Lithium bank is a bit pricey. 100 Amp Hours seems about
right, and should give me 2 hours of run time. Can I augment this
using a 2KW Honda generator and a Converter/Charger? The generator can
double as emergency power at the house, and would provide AC power on
board. One F boat owner reports operating one of these generators in
the port float. I can find 40 A converter that can handle 1100 W
continuous output at 24 vDC. That seems to be about right for a long
passage at mid level throttle.
So perhaps a hybrid type operation, where the generator runs to
recharge the batteries, or to make a long powered passages.
Weight Cost
Torqeedo 2.0 (R?) for aux power 35 lbs $3200
set of group 31 AGM batteries 140 lbs $500
(for propulsion and boat electronics/
40 A DC converter/charger 8 lbs $460
2 KW gas generator 47 lbs $900
(also provides AC power)
Apparently there is a conversion kit that allows you to run a Honda
2KW generator from propane.
Obviously I would need to budget weight /cost for fuel and for
electrical panel, switches and assorted voltage monitors and battery
conditioners.
I am hoping to find feedback on whether this makes sense and what else
I will need to think of. A system wiring diagram of a similar set up
would help, if anyone has one.
My alternative is a 4 stroke engine with a alternative and a couple
of group 24 deep cells. I would top off batteries back at the house.
