Thanks Bill. I agree with you completely, as I am one of the 2 whom I believe have ordered the parts Oliver noted.
I remain a bit confused myself, but I do intend to do my own homework and see if I can make his ideas work for me. In the event I am successful, I will report exactly what I did for others to consider. I would do so in a new thread, so as not to continue this one. I hope that is acceptable to everyone out there. Over and out for now. Thanks, Jamie Phantom A54 #44 |

Hello and welcome to the group;
You will get to love your A54 as you get more familiar with her. A truly magnificent exploration machine.
The inverter is installed on a bulkhead in the engine room, next to the two chargers. There is a remote inverter switch on the generator panel in the galley. When not on shore power and generator is off, you can power the 220V breaker and the microwave breaker by turning the remote inverter switch on.
You should turn the remote switch on, wait for the green inverter light to come on and then turn on the breaker. Keep in mind that you need to make sure that the power draw does not exceed the capacity of your inverter. You can see what size inverter you have by checking the model on the unit in the engine room. On ours we had the 2500 W initially installed. Also keep in mind that inverter rating is temperature related and as the temperature goes up, the inverter capacity goes down. You can also find this information on the spec sheets, when you have figured out what inverter is installed. Also, do not use the toaster function of the microwave/toaster with the inverter.
This is the setup on our 54, yours may differ slightly.
I would like to point out that there are so many systems on board, that getting some training from an experience Amel owner, will help you come up to speed months and maybe years quicker and get a lot more enjoyment out of your Amel. Without sounding like a plug, I would recommend Bill Rouse’s service. He is a knowledgeable previous Amel owner that has circumnavigated and is passionate about Amels and has assisted many on the technical aspects of our complex yachts.
Happy Sailing;

Hello, Amelians, we have long been gratefully following the valuable and helpful exchange of experiences in this great round. We are happy owners of "Soleil Bleu", AM54 / 88, which is currently hibernating in Leros, Greece. We will be back on board in April. Since we haven't known our boat in detail for so long, I have a simple question: on the AM 54 a 24/220 Volts inverter should be installed, so that 220 V can be drawn from the sockets via the batteries even without a generator or shore power. So far I haven't discovered this inverter: where is it installed and how do I activate it? At the control panel there is only a fuse for 220 V sockets. But this does not work without external power supply. Is there anything special to consider to avoid damage. Up to now, we have always switched on the generator to draw 220 V on the road. Thanks for any good advice from you all on this topic, also as a side issue. |

Re: A54 fridge circulation pump
Scott, Oliver states: "This adapter is hooked up
directly to the E51385 Box" Again, you found the exact question to ask. What is the "adapter?" My guess also is that the "adapter" is a relay, taking 12 volts from the Danfoss "fan" output on one side of the relay, and closing 24 volts on the other side of the relay, thus energizing a 24-volt circuit to the VESC which utilizes programmable logic and different sensors to energize a 24-volt pump motor. I believe that this "relay" would need to be installed for each of the refrigeration units. If that is true, and the primary goal is to get longer life from the motor, then why not simply use all of the existing Amel installed components, including the E51385 pump controller, except substitute a 12-volt brushless motor for the Flowjet motor? I believe that Oliver has designed and installed something that works well for him, but we are 68 messages in this thread and the system Oliver designed still eludes enough description for even an electrical engineer to duplicate. I really think that I should shut this thread down because it is very misleading to all of the non-engineers, who happen to be a very large majority of our members. In fact, we are still guessing about this system. I saw where one member has already ordered some components. But, I am very interested in the specifics of Oliver's solution. If we cannot get to a specific duplicatable plan, I will shut this thread down and those interested will need to contact Oliver directly and off-group.

Re: A54 fridge circulation pump
Scott SV Tengah
Oliver,
Thanks for responding. I think you have the best solution we have heard of - we will all be very grateful if we can solve this annoying problem. A few questions for you: 1) Will you be willing to sell me this "more simple adapter"? You're obviously far more versed in electrical engineering than I am. I currently have the setup with 1 fridge and 2 fridge/freezers which each have a Frigoboat W50F compressor. The 1 fridge has a built in thermostat and the 2 fridge/freezers have this thermostat: https://penguinfrigo.co.uk/product/frigomatic-twin-thermostat-for-fridge-or-freezer/. Those are fed to the E51385 Box. 2) My system uses fresh water to cool the fridges. I assume I can put a temp sensor in the freshwater return? The additional complication not necessary for me, but if you think it drastically improves efficiency, I'm willing to do it. 3) Also, given my basic setup, is there a way to coordinate the compressor run times without adding the MCU? I believe I could reduce pump duty cycle if the fridges/freezers would try to run at the same time. Again, if it's too complicated, I don't need it. 4) Is there a 12v pump available? I would rather use the 12v output of the E51385 than put in another relay. I would assume if I use a 24v motor, the way to get 24v would be to use the E51385 output to control a Hella relay, which would then pass through 24v that I get from the posts near the chain wash pump. Since I'm at 80%+ duty cycle, I would rather not have a relay that is energized all the time for heat, longevity and energy consumption reasons. Your solution is the best we've seen and I'm sure many of us will want to copy it. I'm hoping it is something that can be installed and managed by someone without your technical skills. Thanks in advance -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com |

Re: Victron Quattro charger/inverter installation
James Cromie <jamescromie@...>
I have installed the Quattro on our Super Maramu #347. Indeed, the transfer switch capability of the Quattro is currently not necessary for is because of the original transfer switch. I have the Quattro installed after the original transfer switch. However, when/if that switch fails, we now have redundancy, which I consider an important aspect of any system on our boat. Indeed, you're paying a bit more money for the Quattro, but when is anything on a boat ever cheap!

Re: Victron Quattro charger/inverter installation
Scott SV Tengah
I believe for most, the Multiplus may be a money saver.
For me, I wanted to be able to set different current limits for the genset and shore power. For shore power, I set it at 16A. This works 99% of the time. If the marina has 32A supply, I can change to 32A via ve-config software if I really need the additional current. There have been a few instances where I needed to lower it to 9A or less because I'm literally plugging into someone's house/restaurant. For genset, I have the 11kw Onan, so that's set at 50A at all times. With the Multiplus and its one AC input, you can't set differential limits. Getting the Quattro is probably overkill, but my desire is to minimize the number of things I need to remember to manage during the boat's operation. -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com |

Re: Victron Quattro charger/inverter installation
Oliver Henrichsen, SV Vela Nautica
Hello, I do not see the point to buy a quattro and bypass the AMEL shore power switch. If we would not have this switch it makes sense, but with an automatic switch installed? On my boat the multi is doing fine with the original AMEL setup. I split the AC panel, as described in my youtube video. Its no problem to move some breakers and carefully move the labels with them. One side / bus of AC pannel for inverter the other for shorepower/genset. It is also possible to split an AC bus.

Hi Bill, I went out for sailing for the last couple of month and was not able to answer the questions that my thread implied. As there is so much response to this topic and I am a bit more station, I will try to point this topic in the right direction. I am now on Martinique and helping also other boats with technical issues. In the following I will give answers to your commented questions. My (Oliver) statements and Bills comments in red. My (Oliver) answers under it.
a) a 24 V brushless pump, as the name says no wear on brushes like before, only the ballbearings wear and they are easy to change and cost 2 usd. Beside that the original quad pumphead is reused. Most of us got a bag of spares from the old worn pumps. I would go with AMELs 24 V as 12V is a step back and we like to have a well powered pump. b) A brushless motor needs a driver. In this case a VESC is used to controll the motor. VESC is short for Vedder Electronic Speed Controller designed by a clever swedish guy as open surce project. Version 3.x will do. c) to tell the VESC the speed to spinn the motor and start or stop the motor, I use an Microcontroller (MCU) that sends serial commands. This MCU replaces in my setup the E51385 box and the thermostats in the fridge/freezer because the MCU can do much more than only switch the motor on / off. Its the brain of the cooling installation on my boat and provides advanced efficency. To 2. Yes, the VESC controlls the motor speed. To 3. NMEA2K is in this stage of the project not used to controll the system. It only provides system data, like temperatures, to other NMEA2K devices as user information. To 4. The controller is the MCU described above. To 5. This logic is programmed in the MCU that controlls it all. As I said the brain of the system that controlls and comunicates. To 6. See description above. The VESC offers, beside the serial port, a second port, where a servo controller can be used. There is no option on the VESC to be switched on/off by 12V or a Relay, its not designed for this purpose. Please read my more simple aproach below. I designed a more simple adapter with a bit less efficency but that does not need the MCU. This adapter is hooked up directly to the E51385 Box at the pump connection instead of the pump. The adapter tells the VESC to start /stop the pump and adapts the rpm according to the raw water temperature at the raw water manifold. And provides 24 V to the VESC. I guess this is what most owners prefer without need to change the complete cooling controll. It just replaces the brushed pump by a brushless pump and the brushless motor controller. Problem solved.

I'm just deciding between the Victron Multiplus and Quattro inverter/charger and would like to know why the majority of you appear to go for the Quattro. So far the existing Amel AC source selection system which automatically prioritises generator over shore power seems to work okay. Is it just a question of neatness or are there other reasons please? -- David Crisp SV Wilna Grace Amel 54 #58 |

Good evening everyone:
I am in the market for a new main-sail for my SM SN 335. I am replacing a Super Sailmakers vertical batten main-sail that has reached the end of it's life. I had a love hate relationship with that sail. Joel's recommended sailmaker was Super Sailmakers, Peter Grimm, who has serviced me well with three sails in the past. Peter now works for North Sails. I have contacted him for quotes on either a radian cut NorDac or cross cut NorDac main-sail. Alternatively there is a very highly respected rigger in Puerto Del Rey (PDR) Puerto Rico who I have worked with for almost 5 years now and who is a vendor for Neil Pryde sails. He has shown me many high end boats at PDR that he has fitted with Neil Pryde sails. I have been reviewing the literature on these sails. I would be interest in any feedback from those who have either the North Sail radian or crosscut sails or the Neil Pryde sails. Thanks for your wisdom/experience, Gary S.

Re: A54 fridge circulation pump
Oliver Henrichsen, SV Vela Nautica
Hello, My VESC gets its 24V power from 24V Emgine room point. It gets serial bus commands from an ARM32 MCU. My system takes temperatures from inside freezer, fridge, compressor fridge, compressor freezer, raw water temperature in its calculation to controll all cooling needs. It adapts the raw water cooling pump speed according to sea water temperature and compressor temp. This might be over kill but provides the most efficient operation. As you got already digital controlls you may only like to switch the cooling pump. It would be still possible to adjust the motor speed to raw water temp. If you cant setup your own controller I could provide a unit, based on my software, adapted to digital thermostats. My unit also writes a protocoll of the operating times of fridge / freezer and temperature curve with alarms.

Yes our main does have battens. Profurl claims that the slot between the mast and foil creates added lift and thus speed but I can’t attest to that. For us the main advantages of the furling boom are that the main can be reefed off the wind, and of coarse
the sail self-stows when lowered. But I just saw the response from Dennis Johns who has much greater experience than I do and I think he gives you a very good answer!
