[Public-List] Electric power.

[Meinhold, Michael J.]

Richard,
 Thanks for sharing some real experience with an electric propulsion
system for the A30. I would be interested in hearing how it works out on
you extended cruise.

 A few questions-
  Where you stow and operate the Honda generator and its fuel?
  
  Is it wired into the system, and where does it exhaust?

  How many solar panels do you have and where are they?

Continued. We try to keep discharge to about 50%. This only comes into
play if we need to run contionusly for a while. We then run on 1 bank
and charge the other. On day sails usually less than 10% is used and
that is recharged  by the time we need it again. At that depth I just
leave it to the solar panels.  At 3 knots we run about 4 hours to 50%.
We can run 8 hours by switching packs amd charging the off pack.
Concorde says we can take the batteries to 80% discharge once in a while
as long as they get a full charge after. Takes about 4 kw to do 5 knots.
More info as we do the trip. Richard  On 2013-07-13 8:22 PM,
