I lived in Norway 7 years and only saw sea conditions like what you have shown maybe twice. LoL. Anyway: much appreciate the vid namely I''m installing a 20kw on my 40ft masthead sloop with 800ah @ 48v and 1800w bifacial. Lykke til og Fair Winds...
Hello, I really enjoyed the video! It's also very nice to see the victron data at the end. - You are using the SD-15? Do you have the Servoprop? - For how long would you run the motor during the light wind periods? - At what speed under sail would the system begin to recharge? Great to see you successfully cruising with your system!
I have the servoprop. In 3 knots we use 1 kW - that gives us 23 hours, in 4 knots 2 kW and gives us 12 hours. This is without motor sailing. In wind conditions more than 4 knots, we use a code 0 and add the power from the solar panels, and the range increases 4 times. Recharge starts a bit over 4 knots- 5 knots giving me about 200 W ang 6 knots about 500 W
@@silentsea5568 Something doesn’t add up. I understand you have 800 Ah @ 48V battery bank which is equivalent to 38.4 kWh and yet you say that at 4 kts you use 2 kW and your range is 12 hours. Therefore your motor uses 2x12 = 24 kWh of the total 38.4 kWh or 62.5%. How much of the remaining 37.5% (14.4 kWh) capacity is unused because by system design you are recommended by Victron to not go to a 100% depth of discharge (like in a Tesla your typical operating range is 80-20%) to “keep your batteries healthy” and how much of it is instead lost in systems inefficiencies and why? Thanks!
@@magic72it I'm not sure if I have mentioned 800 Ah by mistake somewere, or you are mixing the 800 NM trip with 800 Ah? There are 12 batteries x 1.9 kWh = 22,8 kWh 48 V and 1 200 AH 12 V batteri. There is no info regarding the top/bottom safty margin built into the batteries, but there are no description of not using the batteries 0-100 %. I have tested the batteries down to 7 %, without notecing powerloss in the habour manuvering. Normally, we try to leave at least 20 % before charing, to have some safty margins.
12 x1,9 kWh 48 V batteries, no vind generator, and the propeller generates hydro power. Recommend looking at th-cam.com/video/Q4MVCjXup9k/w-d-xo.html and th-cam.com/video/XJgqKXLEICQ/w-d-xo.html
We use the 2400 W inverter to heat the hot water (1200 W heater). Total domestic consumptions is about 3 kWh including hot water. Motor batteries are 23 kWh. On a good day, we make about 1.5 kW from the solar panels and the propeller, so 2 hours is enough to produce the energy needed. If there is no wind/no sailing for many days and raining, we use the diesel heater. th-cam.com/video/Q4MVCjXup9k/w-d-xo.html th-cam.com/video/YAViE_UE8_8/w-d-xo.html
My Dream is to kill my diesel engine... he is the devil... I sail with the devil always inside my boat... but I have a 44cc from 1996 very heavy... I need to find the right solution. Do you use hydro generation?

Beautiful video ! Silent and clean future !

This is really good to see. Thanks for making this
That was so relaxing to watch. I can't wait until my conversion is done. I'll have 14kwh of battery, but 3.2kw of solar.
Thanks for sharing!! Great information!!

Is there a video of your battery banks - type, size, number etc?

can I ask, what calculation did you use to convert from your old power to buying your motor sizing? I'm stuck on this part.
how many batteries? they in series or parallel? you have a wind generator or hydro generator?

Okay...how did you take hot showers? Solar water heater? Heating with electric just takes too much power, right?
