Re: Recommendations for a windmill/charge controller?
Had an air-X on my boat.? Let's get real! Even 15mph is uncomfortable at anchor. Although the generator would out preformed my (at the time 45 watt panel) in a stiff wind, it was anchor watch time.? The rest of the time the panel out preformed.? My preference is panels, and a good anchorages in windshadows.? Under way the vortex created a wind speed that would help charge the bank.? The best and simple answer for voltage control is a clamping controller. That is of course my opinion.? On Tue, Mar 7, 2023, 9:58 AM Myles Twete <matwete@...> wrote:

Re: Recommendations for a windmill/charge controller?
开云体育Well said Cap’n. ? As example, an AIR-X or AiR403 is about a 3ft diam. windmill and rated for about 400watt peak (28mph windspeed). Folks get excited about the power rating not realizing how the power drops quickly with wind speed. At half the wind speed, a given windmill’s power output will drop by 78%!? So, even with 14mph wind speed, an AIRX or AIR403 can only be expected to deliver at most 50watts.? I can vouch for that as I have used an AIR403 on my boat and one time with a very strong (~12kts) following wind we were seeing about 50watts of power going into the battery pack.? There was an added benefit: With following winds, the drag on the windmill also helps propel the boat. I have since not used the windmill on my boat as it was a pretty sketchy setup and I tend to be a fair weather boater and avoid windy conditions. ? -MT ?

Good morning!
I'm a big fan of wind power and have had Rutland on two different boats. As I'm planning my electric motor conversion, I did some research. The one I'll be going with is the Rutland 1200 48v Terrain charger. Their tech support people say it's no different from their "marine" 1200 except for being 48v. Their charge controller looks a bit clunky but it does a great job. I do recommend the remote display if you site the controller somewhere that's not super easy to get to because you can shut the wind generator down manually with it. Because you don't pay VAT, it can be cheaper to buy directly from them and have it shipped. I'm not certain they sell a mount for the mizzen, but I'm sure you can find something that will work. Best regards, Dena Hankins |

Recommendations for a windmill/charge controller?
Hello!
I have a 30’ Rawson Ketch based in Bellingham, WA. Thunderstruck 10k and 800ah 48v traction with 800ah 12v house. I’m interested in finding a good windmill for some assistance in charging while at anchor (can they be safely run while underway?)…. I have a victron 48v solar charge controller (but I struggle to find any good spot on this boat to locate panels). Can I use this to charge from a windmill? It seems like most systems are sold as a complete package and designed to charge 12v house banks. I’d like to charge the traction battery directly. I can charge my 48v from the 12v using the buck converter or the inverter and ac charger but it’s not very efficient. Any recommendations about windmills? |

Re: Thunderstruck Curtis 1236 CANOpen to NMEA
Here's some others to consider, $126.00 ?And you can get a Saleae logic for $400 which is very versatile.? ? The pro 8 ?channel is pretty nice at $1k.
I own a 16.? It has saved me pain in doing SPI and I2C sensor development in the past. You can also write custom code for the Saleae, I think, to
adjust it to your needs. I think the Saleae is a much better investment – their stuff
works great.

Re: Thunderstruck Curtis 1236 CANOpen to NMEA
The thunderstruck can translator is a good start to figure out what can messages you need to send to your nmea display. The translator sends a message to the controller and it responds with the data, like rpm. If the can translator is connected to the can bus, you can then listen in and use the data you need. This is only a theory as I have not done this?yet. I have heard that thunderstruck is working on a device that will send data to a nmea display. Good luck with it and let us know if you have any success?with it. |
Re: Thunderstruck Curtis 1236 CANOpen to NMEA
Hi Brent, ? It seems that Curtis requires a programming tool which is also available from Thunderstruck to interface with their CAN implementation. The OBD solutions cost much less and require less programming expertise ? I am using an app called OBD Fusion for IOS on an Iphone with a bluetooth OBD dongle on the CAN translator. I got Curtis user defined PIDs from Thunderstruck and it works fairly well.? i am now going to install dedicated displays for Voltage and amps right off the battery bank. Then I will only need the OBD display for RPM and motor/controller temps.? ? ? |
Re: Thunderstruck Curtis 1236 CANOpen to NMEA
开云体育Hi Brent,? The Torque app will do the translating for you. It can be a little tricky getting it to work at first but sounds like you’re not afraid of tech.? I would start with that at least and the you can get creative.? I believe most people are using android. Have not seen a good IOS option yet.?

Thunderstruck Curtis 1236 CANOpen to NMEA
Hi all.?
Last year I ripped out an old Perkins diesel and replaced it with the 18kw sailboat package from Thunderstruck. Most things have been running smooth except for the battery indicator always being red and the controller giving error messages when the charger is on but those are for another thread. I have searched for threads on this but I always come up empty with anything actually helpful. What I'm trying to do is get RPM, temp, Amps, etc messages from the can bus to either the NMEA2000 bus or at least into SignalK so I can view it from multiple devices. I have a RaspberryPi setup with a CAN hat from Waveshare. I'm able to see the raw CAN messages through cansniffer and candump but I'm stuck at translating those messages into anything meaningful. I know there are dozens of videos about translating CAN messages but almost all of them are about cars. I do have the OBD translator from TSM but I have yet to find a OBD to USB connector that will work and honestly would prefer to pull directly from the CANOpen bus anyway. Has anyone gotten anywhere with this or have any resources that might be helpful? I'd even be willing to pay a consultant to get me over the hump here as it's driving me crazy. Thanks in advance!! |
Re: Ventilate a LiFePO4 battery space on a boat?
The only reason for ventilation I'm aware of is for temperatures.? Passive (or even none) might be enough, depending of battery capacity, expected charge/discharge rates, and what else might be in the same space.? Short answer is that LFP cells won't 'outgas' except in extraordinary conditions.? Similar to an SLA battery in that regard.

Ventilate a LiFePO4 battery space on a boat?
I think I know the answer, but just in case I’m missing something, would it be advisable to provide ventilation to a LiFePO4 battery space on a boat? Active, passive? I know they are designed not to vent gasses, but the question came up and I don’t have a definitive answer.
