Good morning ,
I received the dyneema loops by Amel and ask now the group for any advice or recommendations for the way to Change the loops at the Antal Block. First try after getting out the screw was without effect to get out the roll.Will I loose the balls of the bearings 
Thank you very much Wolfgang Weber SY Elise Amel 54 #162 on Delaware River to Cape May ( any recommendations for Marina or anchorage?)

Hi folks,
We will be wintering ashore this year at Ardrossan, Scotland where there is a possibility of subzero temperatures and I intend to take measures to combat possible damage due to freezing. I’ve never wintered in such conditions, so it’s a new process for me. I’m comfortable with the obvious stuff like empty water tanks, drain lines, anti-freeze in engine/gen raw water coolant lines etc.

One area that is puzzling me a little is the watermaker system. I’m thinking about some kind of non-toxic antifreeze solution?  

What do others with such potentially sub-zero wintering conditions do with their watermakers?

Many thanks
Dean

Hello all,

What are your thoughts on using a para-anchor or storm rated sea anchor type setup?

Hi Scott;

 

Very impressive numbers. I am familiar the Lithium battery technology and all the benefits you mention, since we have been using it in giant scale radio control airplane models (Up to 60% scale) for years.

 

The one major issue with lithium that has prevented us from making the change to Lithium on Kokomo, has been safety. There have been many cases of these batteries burning down models as well as houses, when the fire happened to occur in the house.

 

In most cases the issue has been misuse or equipment failure, that has led to overcharge/discharge but some that seem to have been without any external input and not during usage  As far as I have observed, , once the fire starts, it cannot be extinguished with standard firefighting equipment. It basically seems to need to burn itself out.

 

Do you know which lithium technology Mastervolt uses? (Lithium Polymer, ION, LIFE, or ?) Did you ever happen to address the safety and evaluate the hazards with this technology? What was your conclusion and how do you view the hazards associated with these batteries?

 

I would also be interested in seeing a picture of your solar setup, if you have one. Thanks for posting all the useful information and data.

 

 

 

Respectfully;

Very interesting re serial vs parallel. I do find a big drop in production with shading, much better days if the wind keeps the solar pointed towards the sun. I’ll have to run a bit more wire to the mppt. I’ll try that in NZ and see what we get. Thanks for the suggestion!!

 

Appreciated

Porter, 

I guess you mean far from the panels to the mppt? 

Maybe you can experiment with parallel to see if you get higher output. I believe parallel is better than serial when you have shading on some panels and not others. 

I have the 3 pairs of wires from the panels to a switch in the aft lazarette.  Then one pair from the lazarette to the mppt which is behind the main switches in the passage berth. Of course the batteries are near there. 

Seems to be no problem with the distance as I'm getting up to 6500wh per day as you can see on the data I posted earlier.

Mohammad,

Both Victron, which I have and Mastervolt use lifepo4 chemistry, a much safer (but less energy dense) technology than the lithium ion that is more common. I don't know much about RC planes, but I assume for weight, they'd go with the lithium ion, which is far more prone to catching fire and when they do have thermal runaway, burn much hotter and are likely to ignite adjacent cells.

I'll write about my thoughts on safety in a later post. I'm sure you know about the relative safety of lifepo4, but here's a FAA fire hazard analysis done on the various battery types as they are often used in real airplanes. I read this last year before I was contemplating adding lithium to my boat.

Lifepo4 is shown to be safer than the other lithium chemistries. 

https://www.fire.tc.faa.gov/pdf/TC-16-17.pdf

While safer, it's not without risk. Then again, neither is lead acid as I personally know the owner of an Amel who experienced an unexplained lead acid battery bank explosion. Luckily no one was sleeping on the passage berth at the time.

The JIC is a designation of the connection. It does not necessarily have to be reusable. Most are not. I will bet that a hydraulic shop can make you the hoses with stainless steel fittings permanently pressed on.

Did you bring a hose to a bigger hydraulic shop?

Eric, thanks,
It turned out to become a problem here in Faro, Portugal. JIC looks like its not so available in europe?

Hi All,
I ran into same problem and the hose from high pressure pump came off before i could change my hoses.
Does anybody know how these terminals are caled? What kind of connector is that?
Since I learned here that the end fittings are reusable i will order the hoses in France.
Dessalator did not give a hint that I can reuse the fittings.

Hi All, im about to order new HP hoses from the dessalator rep in the US. The end fittings are reusable and so you only need to buy the hose unless like me one of your ends are damaged.
There are 2 options for this.
1: buy the hose from France and any ends that you need. Hose $40 fittings $93.00 each, shipping $70
2: buy new hose and ends from the US. the hose is different and the fittings are slightly different with the same threaded ends. They are not interchangeable. Cost of 2 new hoses $472.00
I'm buying the hose and 1 end fitting from France.
If anyone else wants to buy either hoses or fittings from France and add to my order please let me know by Thurs 25th by noon eastern time. The order will be shipping to me in Annapolis and i'll forward from here if you pay shipping to your destination.

I need to replace the springs in one of my Antal genoa cars.
The springs and block are attached to the car by a stainless rod that runs
from fwd to aft and is dead ended at the aft end.
There is a split pin through a hole in the rod to prevent the rod from
coming out.
I can't turn the rod to get the split pin out...and even if I could I doubt
that I could get the rod out.
Has anyone done this before?
Any advice on how to remove that rod ?
Thanks

Hi

The aft lazarette shore power breaker is mounted in a plastic purpose made housing with just the breaker switches protruding.  The manual transfer switch is housed in the original housing of the original contactor, after a little cutting.

No, I was not able to source a galvanic isolator here but it is on my to-do list.  What size galvanic isolator is required?  With 20A breakers I suppose it makes no sense to go for a higher rated galvanic isolator for the earth connection.

Very cool...Hope I’m able to still do that when I’m 82. This is my cool ne airplane.

Hey Scott, thank you and I was figuring a 5000w inverter upgrade (Maybe a 7500w when available)to run all from 24v when possible, I too have a Bauer junior. I guess then genset is still a great reliable generation item and needed for those jobs, but’s it is great to live off batteries most of the time and look forward to the day when it’s easy.

Nice sharing with you and thanks for the advice

Paul,

At the risk of costing you some money on upgrades, I will say that being able to run all the 220v appliances without the genset is one of the biggest advantages of having lithium. Especially the washing machine as it takes such a long time and has such variable draw but a low average draw, so you're unnecessarily adding runtime to the genset unless you batch it with a lot of other uses.

We have the Victron Quattro 24v/5000va/120amp. At 5000watts, more or less, the only 220v appliance that won't run is the Bauer Junior II scuba compressor. And that's only due to the startup current required. I can probably start the scuba compressor with the genset and continue with the inverter. With your mostly Mastervolt setup, I'd suggest sticking to Mastervolt so the batteries can talk to the inverter. But I'm sure Mastervolt has a similar product.

The danger of having that much inverter capacity is that people sometimes think it's really like being at home. The admiral has been known to run the electric boiler, induction stovetop and microwave at the same time on battery/inverter. With respect to the batteries, it's only around half the recommended continuous draw, but it still makes me cringe!
