Arno, that's exactly what I'm looking for. Do you recall where you read such advice? I'd like to understand more.

I have an Alpha Pro regulator, and if I don't need to change it to a Pro II/III, then I won't. Tho Pro can be adjusted manually to provide a Lithium compatible charge profile, and I have no other need to set up any Masterbus infrastructure in my new system.

I'm going down the Victron path, and if I REALLY must change my regulator, then I am more interested in a CAN-Bus device like the WakeSpeed product ... but that's whole new can of worms ūü§Ē
My hope is to stick with the original regulator and keep the lid firmly on the worm-can.  Potential for alternator overheating is the one issue I want to understand more about.

Passageway berth wall fabric cleaning advice

Paul Guenette
 

Hello,

I am looking for some advice on cleaning the fabric on the wall of the passage way berth.

I spent this past winter in the Pacific North West. While in Comox BC Canada I have been using a dehumidifier and also using the exhaust fan while using the propane stove to help reduce moisture in the boat.  Over the course of the last six months the fabric on the walls of the passageway berth has started to get a little discolored in some spots. Attached are a couple of photos.

I am wondering what products and methods of cleaning others have used on this fabric.

I appreciate your advice and feed back.

Thank you, Paul

Dean,

I'm going to the boat in 3 weeks to install the lithium batteries.
Then I will check the functioning of the whole system (alternator, chargers, inverter ...) with temperature readings of the alternator, batteries and cables.
I will then be able to tell you more.

Re: Raspberry Pi

Bill Kinney
 

I use an R-pi4 to collect, save (using InfluxDB) , and display data (using Grafana)  from my Victron system while we are off grid and unconnected to the internet.  It draws very little power itself, and was scary cheap, even with a 250GB SSD to hold data.  I installed it without its own display and keyboard, just looking at data with a wireless connection from my computer or tablet.  

I'm not a huge computer nerd, and would just assume avoid those kinds of details, but it wasn't that hard to configure with suitable internet tutorials holding my hand. 

Victron's level of support for things like this that are officially "unsupported" is great.  https://github.com/victronenergy/venus-docker-grafana

Re: Mastervolt Alpha High-Output Alternator Temperature when charging LiFePO4

Arno Luijten
 

When you change the alternator controller from the original AlphaPro to a AlphaPro II or AlphaPro III you will find an enclosed temp sensor in the package. You can configure the alternator controller to have the temp sensor monitor the alternator instead of the batteries.
In my case I also added a Mastershunt to the system. This shunt also comes with a sensor and broadcasts the battery temperature across the Masterbus network. This way you can feed both the battery and alternator temperature to the AlphaPro. It also enables some more control over the AphaPro.

I'm not at the point of installing Lithium given the charge/discharge/SOC complexity but I did prepare my electric system as far as I could to install Lithium at some point in the future. Mastervolt is very much double in it's advice to monitor the alternator temperature. I've seen publications where they do advise to put a sensor on the alternator. In my case it was simple as it did not require additional things to buy. Knowing the alternator temperature is also useful to anticipate on some of the problems that may develop (worn out bearings etc.)

Re: Mastervolt Alpha High-Output Alternator Temperature when charging LiFePO4

Hi Dominique,
Thanks for that information. You're quite correct, that is the temp sensor which Mastervolt recommend for third-party (cheaper) alternators. It is indeed an extra protection as you suggest.

However, Mastervolt state very clearly in their documentation that this sensor is not needed with the Mastervolt alternator.  What I really want to know is whether their statement is true in practice when charging Lithium batteries.

[Reason: correction on Volvo Penta pricing.]

Good point Dominique. 

I looked at the Volvo Penta parts diagrams for the part numbers and found the following:

For D3-110i-A, the part number is 
31355464
http://www.marinepartseurope.com/en/volvo-penta-spare-parts.aspx?Catalog=7744550&Category=26&View=6722
The price is $211usd

Here's the exact same Bosch part, without the "Penta" packaging and it costs $56 USD. 
https://www.fcpeuro.com/products/volvo-boost-pressure-sensor-map-sensor-0261230090

For D3-110i-B and D3-110i-C, the part number is
31355463
http://www.marinepartseurope.com/en/volvo-penta-spare-parts.aspx?Catalog=7744550&Category=26&View=9364
The price is also $211usd. 

Exact same Bosch part, missing the Penta on the box. It costs $25 :)

Paul,
I replaced my D3-110I-A with a Beta85 engine.
If you want to know what triggered my decision and how happy I am with the new engine, please write an e-mail o alexramseyer@....
As a result of my change, I still have the electronic black box of my D3-110I-A as well as other parts available if someone is interested.

Re: Mastervolt Alpha High-Output Alternator Temperature when charging LiFePO4

Dominique Sery
 

Hello,
 
My batteries need to be changed and I'm switching to lithium.
I bought a Mastervolt alternator temperature sensor 41500400 (19.80 euros)
With the Masterbus to USB interface you can choose the alternator temperature  with the Master adjust software and the voltage charges, with your laptop.
It will be an additional security.

Mastervolt Alpha High-Output Alternator Temperature when charging LiFePO4

Dean Gillies
 

Hi all,
This question is for owners with installed LiFePO4 batteries using the Mastervolt Alpha alternator (110A or 150A) as originally installed on many 54s. 

Mastervolt state that these alternators do not require a temperature sensor to monitor alternator temperature, the implication being that they will not overheat,  There is no graceful degradation built-in, and presumably if the alternator really does overheats then it will simply fail completely.

I wonder if this statement by MV holds true in practice with the large LiFePO4 banks now being installed, where the alternator could be asked to deliver maximum power continuously for a period of 4, 5 or more hours?


Has anyone experienced an alternator failure caused by overheating when charging for long periods?

Mastervolt offer a temperature sensor for third-party alternators which can be used via the Alpha Pro II/III regulators’ Masterbus interface. This allows the regulator to first derate, and then safely disable the third-party alternator if the temperature becomes too high. Has anyone felt the need to install this option with a Mastervolt alternator?

I will be changing to LiFePO4 when I return to Stella and I’m just planning my approach to managing the alternator interface.

The wiring harness for the fault MAP sensor on my original, Amel installed Volvo D3-110C connected perfectly to the replacement Bosch 31355463 sensor. Further, the after cooler mounting location for the MAP sensor has two screw holes that the 2-wire sensor pictured above would not fit into.

I have run this sensor for a few hundred hours with no trouble and as Arno mentioned, the housing is completely plastic. I have also verified that the engine remains isolated.

“I am not sure that is the correct part number for Amel-specific isolated ground. It is a different number than I received from Amel Martinique. "

Given the all plastic housing of the sensor I don’t think there is a isolated ground version of this sensor. The difference between the connectors may have to do with the version of the D3-110
