Hi Chris. I will be here till mid day Monday and then sailing north to Mangonui. Happy to see you here or in Mangonui. The mizzen did not need to be removed. I did the job from a bosuns chair.
Kind regards
Danny. I will pm you with my phone no.

The top of the mizzen is the ideal place for a rubber mounted "Super Wind" generator.
From the output curve I calculated about 4KWh of power/24hrs in 20Kn of wind. That is impressive.
My old wind gen never did anywhere near that.
Do you have a photo or a diagram of your mounting set up.
I wonder if this could be installed without removing the mizzen?
How long will you be at the Opua work dock.
I would love to come and see your set up.
My son has a drone & can take some close up photos if necessary.

I was fortunate to select a Super Wind and to place it on top of the mizzen. It is sient in all wind strength, and I mean silent not heard at all. There is a yacht just down the marina from me with two mounted quite low. Walking past can't hear a thing. It is vibration free, and I mean totally vibration free. It is designed for remote locations where maintenance is impractical. (Not sure if they were thinking about the top of a mast). It's blades are geared and feather mechanically automatically, not by Blade distortion like some. The design has total feathering above 40 knots so no need to fear it self destruction in storm force wind. Mounting. There is an oblong plate on top of the mizzen that extends beyond the extrusion
A hole in each corner and a matching plate on the bottom of the generator mast and you are done. I have a 5mm thick piece of hard rubber between. Nil nil vibration. Output. The graph provided with the unit shows minimal output at 10 knots good at 15, and excellent in wide 20 knots and above. I have two solar panels as well. Sunny and still, they do the work. Windy and cloudy super wind does the job.Sunny and windy. Wow. I see you are in NZ. I am on the work berth Opua marina this week. You are welcome to visit. Pedigree is on the main marina with the same set up.lastly my first one lasted 10 years before the bearings wore and I replaced it.

Thanks for your reply Jose, I would be most interested in any ideas or comments.
I have numerous reasons for getting rid of the wind generator:
1. I want to be able to able to fly the Mizzen Ballooner.
2. I now have Lithium Batteries & my electrician said the wind generator does not work well with Lithium.
3. Even though the wind generator is a "silentwind" it is not silent.
- When the wind gets up to 25-30Kn it puts a vibration through the boat (only 10A~240W).
- I also do not wish to annoy my neighbours (or my partner).
4. Mostly it outputs between 3A-5A in 15Kn. In these conditions it is reasonably quiet.
- good for trade winds but not NZ.
Questions:
1. Can anyone tell me how difficult it is to put the wind generator on top of the mast. I assume:
- the Mizzen needs to be taken out,
(probably only worth it if mizzen needs to be taken out for other reasons)
- aluminium fabrication required.
Costly, I would love to know how much. Solar arch is also costly.
2. I assume to make this work for lithium:
- Rewind the wind generator to a voltage significantly higher than 24V AC, (thinner wire, more turns??)
- Rectify 3 phase AC into DC,
- then use MPPT so it is controlled along with the solar panels.
I would be interested if anyone has done this and integrated it into a LFP system.
3. I would be interested how others found the noise & vibration.
Maybe it could be rubber mounted??
4. Is it worth fixing/replacing? (cost/benefit??).
In Trade wind areas 400W wind generator - is probably equivalent to 300W - 400W of solar
In Non-Trade wind areas 400W wind generator is probably equivalent to 100W - 200W of solar
My Conclusions:
I suspect wind power, particularly for boats with LFP batteries & for boats outside the trades has had its day & once it is broken it is not worth fixing particularly if difficult fabrication (top of mizzen) is required.

Hi Nicolas, I have the 350. No I dont have lithium but from another post I understand the issue is with the need to be able to switch off input power at times. The Super Wind has a stop switch to mount in the line from the WG to the batteries. It shorts the delivery lines together and separates the batteries from the feed. The shorting together of the delivery lines creates resistance and all but stops the blades turning. This is useful if extreme winds are encountered but in my 13 years I have never used it for that. The highest wind I have sailed in was 60 knots plus but it is possible that on the mooring higher winds occurred. I find the mechanical self feathering does the job well. I got 8 years life from my flooded lead acid batteries and I believe the constant state of charge achieved with the wind gen and the two solar panels I have mounted on the rail are the reason. When not aboard I leave two fridges on the give some load.
Kind Regards
Danny

No the bank is one, the LFP is just added as if it were another AGM. In effect it gets charged first and is discharged first. See this article https://www.zwerfcat.nl/en/lithium-hybrid.html
it explains very clearly what is going on.

That was one of recommendations from WG controller manufactures. Second was to connect one lead battery in parallel. The person said that paralleling different chemistries “no-no” is a myth and it will work just fine. But I’m not so sure about that. I also bought a Superwind having consulted the forum. To replace Rutland 1200. I agree with Danny 100%.No noise, no vibration. Mine is located on my arch. There would be more wind at the top of the mizzen. The engineering is superb. When it arrived, I unpacked it and could only marvel at the components, their quality. I asked the manufacturer about use with Lithium, they said it will work just fine but if one wants to adjust the charge profile to send back the controller. There is also a small DIY component one can fit into the charge controller. I have the stop switch. I shut it down to clean my solar panels. I also take off the blades and the tail fin when I leave the boat. This is really because the travel lift, at the yard in Leros, is not a huge one and their cross beam would foul it when setting the boat down on the ground. I have a hybrid AGM:LFP bank. The WG works just fine.. I find it great when sailing in breezy conditions at night. The autopilot is working hard on top of the usual demands on the batteries. Nice to have the extra amps. What is absolutely true is that it is an expensive bit of kit. You get more bang for your buck with solar…I like the combo though.

Hi Chris, I have the Air X Marine 400 W/24 V wind generator standing on top of the Mizzen and am in the process of change to LIFePo4.
For use with lithium you will need to replace the old circuit board by a new circuit board fit for lithium. ( With the older versions of the Wind generator ( still made under South West Windpower)
The NEW Primus wind power generators on market all have a circuit board that is fit for both lead acid and lithium.
I just did that and it costs Euro 235 excl VAT in The Netherlands. So no extra MMPT ! As the wind generator was already on my mizzen when I bought the boat last year I figured that it would not harm to have some back up charging when the sun is not shining. I already had replaced the bearings last year. If it will pay off? Still have to find out! The new circuit board will shut off the wind generator when he measures 28.2 V ( factory setting) at the batteries. Just like with the lead acid but than at a different voltage.( Cant remember what voltage) If you like to know more about it visit http://www.primuswindpower.com/wind-power-products/manuals . Look under "Tech_Note_-_Lithion_Ion_8.6.20.pdf" If you would like to shut off the Wind Generator earlier than at 28.2 V battery voltage or to keep the blades silence I still have the windgenerator electric brake and the main wg breaker switch. This all will turn the wind generator on the brake out of generating power. In my system I have however a Victron Cyrix-Li-Charge intelligent charge Relay to which the Wind generator and the Volvo alternator are connected. I am actually not sure if it is required but my electrician recommended it. An extra safety I guess. Regards Eric Opdeweegh sv Abayomi Super Maramu 158 The Netherlands

Hi Chris, one thing I forgot to mention. The Super wind has an off switch for use in very strong winds or if service down stream needed and power needs to be turned off. It shorts the feed wires together which stops the blades (or dramatically slows them) and separates from the batteries.

I was fortunate to select a Super Wind and to place it on top of the mizzen. It is sient in all wind strength, and I mean silent not heard at all. There is a yacht just down the marina from me with two mounted quite low. Walking past can't hear a thing. It is vibration free, and I mean totally vibration free. It is designed for remote locations where maintenance is impractical. (Not sure if they were thinking about the top of a mast). It's blades are geared and feather mechanically automatically, not by Blade distortion like some. The design has total feathering above 40 knots so no need to fear it self destruction in storm force wind. Mounting. There is an oblong plate on top of the mizzen that extends beyond the extrusion
A hole in each corner and a matching plate on the bottom of the generator mast and you are done. I have a 5mm thick piece of hard rubber between. Nil nil vibration. Output. The graph provided with the unit shows minimal output at 10 knots good at 15, and excellent in wide 20 knots and above. I have two solar panels as well. Sunny and still, they do the work. Windy and cloudy super wind does the job.Sunny and windy. Wow. I see you are in NZ. I am on the work berth Opua marina this week. You are welcome to visit. Pedigree is on the main marina with the same set up.lastly my first one lasted 10 years before the bearings wore and I replaced it.

Thanks for your reply Jose, I would be most interested in any ideas or comments.
I have numerous reasons for getting rid of the wind generator:
1. I want to be able to able to fly the Mizzen Ballooner.
2. I now have Lithium Batteries & my electrician said the wind generator does not work well with Lithium.
3. Even though the wind generator is a "silentwind" it is not silent.
- When the wind gets up to 25-30Kn it puts a vibration through the boat (only 10A~240W).
- I also do not wish to annoy my neighbours (or my partner).
4. Mostly it outputs between 3A-5A in 15Kn. In these conditions it is reasonably quiet.
- good for trade winds but not NZ.
Questions:
1. Can anyone tell me how difficult it is to put the wind generator on top of the mast. I assume:
- the Mizzen needs to be taken out,
(probably only worth it if mizzen needs to be taken out for other reasons)
- aluminium fabrication required.
Costly, I would love to know how much. Solar arch is also costly.
2. I assume to make this work for lithium:
- Rewind the wind generator to a voltage significantly higher than 24V AC, (thinner wire, more turns??)
- Rectify 3 phase AC into DC,
- then use MPPT so it is controlled along with the solar panels.
I would be interested if anyone has done this and integrated it into a LFP system.
3. I would be interested how others found the noise & vibration.
Maybe it could be rubber mounted??
4. Is it worth fixing/replacing? (cost/benefit??).
In Trade wind areas 400W wind generator - is probably equivalent to 300W - 400W of solar
In Non-Trade wind areas 400W wind generator is probably equivalent to 100W - 200W of solar
My Conclusions:
I suspect wind power, particularly for boats with LFP batteries & for boats outside the trades has had its day & once it is broken it is not worth fixing particularly if difficult fabrication (top of mizzen) is required.

Hi Chris,
Be careful with Wind Generator (WG) charging of LiFePO batteries, you should be able to somewhat easily stop the blades from spinning when you need to.
- Unlike Solar, WG always produces energy (given there is wind), this is why you will see diversion or "load bank" installed with WG. the way it works is that when regulator senses battery full, it temporarily diverts flow into the load bank. Load bank could be a set of resistors, or a water heater, or a fan that can take unwanted energy and "dump" it.
- MPPT won't work with WG out of the box. I spoke with few manufactures on this subject and they all said it's not going to work. During this process I also discovered that WG is not as popular as Solar and there are not that many options for WG regulators. Additionally most regulators are not designed to work with LiFePO batteries.
- One thing with WG regulators is that in case of open circuit, the regulator will default into "unregulated voltage" mode. And this is where it gets very bad very quick.... a lot of people forget that LiFePO has a BMS and can shut off itself, in essence creating open circuit environment. In the case of Load Dump everyone immediately thinks of Engine Alternator and many forget about WG.
One case you should be very aware of is that if your LiFePO battery charge gets full and then depending on BMS it can either shut off charging or charging and load. At this point all the energy from WG is no longer flowing into the battery and has to go somewhere. Usually before even getting to this point WG regulator should have sensed battery SOC and started diverting energy to the load bank, but image it did not. I think of a few reasons why it did not do its job. When wind is strong enough, i.e. good current flowing, this current blows the fuse to the WG regulator quickly. When this happens, WG regulator has no more power and the system defaults into open circuit mode, which results into "unregulated voltage" flowing through the circuit. If the wind blows 20-25knts the circuit will see 35-46V coming from the WG. if Red Switches are ON, this high voltage will start to flow into the circuit. At his point many electonics onboard are not going to like what they get Voltage wise.
That is one scenario, but even if you pop the breaker to WG and deal with the aftermath, the problem still continues, as I mentioned before, WG always produces energy and now this energy is not going anywhere. At this point, in the worst case scenario, WG can create fire, so to prevent this you either have to tie off blades or divert energy into the load bank. If you did not prepare for this scenario, electronic diversion (or some call it break) won't work, since regulator is no longer operational. so the only option will be to tie off the blades, which is not going to be an easy task given good wind and it wont be possible if WG is somewhere up hight on the mast.
Hopefully this makes sense and you are aware of possible risks with WG charging of LiFePO.

I'm not sure if this is the correct place to advertise to "Amelians" but this bracket is perfect for SM2000.
"silentwind" generator - good for parts - needs a new controller. Some minor aluminium corrosion
Bracket - Aluminium - some minor corrosion - Also could be used for radar.
Pick up Town Basin Marina, Whangarei.
