Hallo Hyprdv, The Green Motion works exactly the same way as your Solomon system setup , we need to push the throttle forward to get to regenerating, we set the throttle to optimal regenerating since this fluctuates with speed and state of charge with the battery
( is that the same in your system )
The lifting mechanism is wonderful , hydraulically operated with a electric pump
and a hand pump for backup. there are 4 GreenCats in the water shortly followed by another 2 due to be launched this spring and summer. You are right that a fixed prop will slow you or us down by around 1 knot
and when regenerating that is no problem , we are getting our moneys worth in energy but when we do not need the energy being able to lift
the complete system out of the water and the extra knot is really helpfull specially in low wind
conditions , doing 5 or 6 is a 20 % speed difference !!
Another advantage is the with the motors out of the water we can point significantly better, 45 degrees app with the props down and 35 with the props up . I am glad you are happy with your system I feel it is wonderfull to cross an ocean with out using any fossil fuel
, do the cooking
and all else with self generated energy is the future , do you also cook electrically.
While cruising when we need energy we just lower one drive leg and generate ( Depending on speed ) between .5 kwh up to 4 kwh the first with 6 to 7 knots and the 4 kwh with 12 knots of speed. I have seen as much as 5 Kwh at a speed of 15 knots .
Once the batteries are full ( 170 volts ) the motors automatically go into free spinning mode , we get a signal and lift
the motor(s) out.
The next boat to be launched has a new type of Lithium batteries that save us around 250 kg of weight and use significantly less space compared with the previously used Mastervolt units and give us 28 Kwh usable power before having to start a generator
or 5 Kwh extra.
A real plus.
