Chris,
I'm wondering about drag while you were making the 18 amps. On your tri that speed isn't much of a problem and the size/weight of your boat shouldn't give you much of an indication of slow down, I'm just curious if you noticed.. Dave K

Hi Erik,
I've seen some regen on Current Sunhsine which has a Cruise 4. Its
not recommended by Torqeedo, so keep that in mind if you want
experiment with this. If you do it you may lose warranty.
If I set the throttle at around 50 watts or some other low number,
then when the boat is sailing the power requirement quickly drops back
to zero, and then from around 5 or 6 knots I begin to see 1 or 2 amps
coming in. I've seen as high as 18 amps when she was doing about 13
knots. And it has been regenerating when I've had her at 25 knots and
the motor was screaming but I did not get a chance to see what the
amps was. That was accidental :) But it didn't blow up the motor, so
I think they could be robust enough for more genatle use.
This regen is at 48 volts so at 18 amps that was a respectable 900
watts coming in. But even at 2 amps, thats 100 watts and is enough to
easily meet my house load requirements and a bit more besides.
Cheers
Chris
