Yes. The button on panel is down of course 100AMP. Everything has worked fine since 2018 June when we bought Vista. But I will check the fuse under the hood. Thank you for showing me. Can there be fuses on the battery bank also? Kindest regards Arthur

Re: Victron multiplus 2 24v/70/3000
Some really great and focussed information in this thread. If you want to connect all your onboard AC consumers directly to the MP3000 then you will most likely need the -50 model, especially if you have a generator onboard as this can easily generate more than 16A@230V. Ps Dan, thanks for the data points regarding the 65/70A charging. I observed this last season on my system, but had not given it much thought.

Onan is not charging the batteries?
Arthur Sundqvist
Hello !
The Onan Genset is not charging the battries. All else is working, Clotheswasher, outlet, Isotherm. The red ledlamp about FUSES is on, and green on ....... Where is the fuse or fuses. Are they on the batterybank? Does anybody know? How do I solve this? Thanks for answering me.  We are now in Whangarei NewZaeland, coming all the way from Sweden. SM435 VISTA Kindest regards Arthur Sundqvist

Re: Victron multiplus 2 24v/70/3000
I think it is worth adding my experience as well. I replaced my Dolphin 100amp charger with a Victron Multi-Plus 3000/70/24 inverter/charger. I chose to use the existing cables from the 100amp charger. They are not labeled but they are at least 50mm (between 1 and 0 guage) size. The Victron manual recommends 1x50mm for up to 5 meter run, and 2x50mm for 5-10 meter run (sum of positive and negative wire length). The run from the battery switch to the Multi-Plus is about 5 meters each way (10 meter run length), so arguably the 2x50mm is in line with Victron recommendation. However one 50mm cable is well within the ABYC standards. Now a bit of theory: cable size versus current is based on 1) resistance causing overheating and 2) voltage drop across the cable (also due to resistance over the length). Two small of a cable size can lead to overheating and fire. But the longer the cable run for even an appropriately sized cable will create a voltage drop across the run that can impact performance. That larger voltage drop is due to higher resistance across the run, but the heat generated from that resistance is also dissipated across the longer run. The wire does not get hotter because the run is longer. Also: if fire was clearly a risk, then ABYC would not allow a 300amp fuse on a 50mm guage wire. So what is my experience with my application: 1) charging - in my application I have set my Victron Multi-Plus with two internal limits: a) I derated the charging limit to 65amps. The 70amp Victron capacity is based on optimal cooling of the unit. You don't get this in the Amel engine room! When I first installed the unit I quickly saw that it did not put out 70amps for long before the fan came on and it started internally cutting back on the charge output. By lowering the initial charge output I may protect the unit a bit from the heat stress (actually after an hour with generator and watermaker and Multi-Plus running in the engine room the Victron output will still drop to about 60amps). This charge limit also gives me a few extra amps capacity when I'm running the generator to comfortably run the water maker and perhaps the water heater or washing machine (after the heat cycle has completed). The bottom line is that the maximum charge current is 65 amps. 2) inverter - my highest load appliance is a water kettle which pulls right at 100amps from the battery for the minute that it takes to heat a pot of water. My induction hob pulls about 70amps from the battery at the higher settings (cycling up and down when temp is achieved). The washing machine heat cycle pulls about 70amps (cycling in and off during the first 5 minutes of the wash cycle). Nothing to overheat a 50mm guage wire! As for the voltage drop? When I have run the water kettle in the morning with a 25% SOC on my Li battery bank, the battery voltage at the bank Victron BMV reading dropped from about 26.0v to 25.5v by the end of the heating cycle. The difference between the voltage reading from the BMV and the voltage reading from my Victron Multi-Plus was about 0.2 volts. So that's less than a 1% voltage drop. On the charging side it is critical that you provide the Multi-Plus with the battery voltage from the shunt at the battery to optimize your charging (particularly if you are charging Li batteries. My Amel SM was originally equipped with an inverter and circuit. I used that wiring for the output from my Multi-Plus. And the circuit runs through a junction box behind the 230v panel and I installed a 3way switch that allows me to supply power from the inverter to the 230 panel to run the water heater (600watts), dishwasher or AC ... I hope that helps simplify things for some SM owners considering the Multi-Plus 3000/70/24. I'm happy to answer any additional questions. Best regards, Daniel Carlson on sv BeBe SM #387

Re: Victron multiplus 2 24v/70/3000

I have installed Victron inverter/chargers on several Super Maramus now. It is not a drop in replacement. An inverter/charger is just different beast than a straight charger. The DC wires to the Victron will need to be larger than those used for the 100 Amp Dolphin, for example, fused differently, and the AC wiring from the transfer switch needs to be at least rerouted, complete with breakers. If you have a high output generator (> 6KVA) there will also be quite a few design decisions to be made about what runs off the generator, what runs off the inverter, and what runs off either. Implementing those decisions can be require quite a bit of rewiring of the AC distribution panel. The ease of the mechanical installation varies a lot from one SM to another depending on how the original equipment was installed. In the case of our older Amel, the Victron pretty much just bolted right into the mounting bracket for the original large Dolphin. New boats required a bit more creativity.
All those complications aside, the Victron inverter chargers are fantastic pieces of kit. They really do add a lot to the livability of the boat. In my experience, they have been very reliable. I would not suggest mounting any inverter/charger (or large charger, or inverter!) inside the cabin space. While it is nice to be able to run short cables, these units are (to my ear) quite loud. When inverting or charging they have make a 60 (or 50!) cycle hum that I find very annoying, and when pushed hard enough to run the cooling fans they would drive me bananas. Amel design isolated everything possible that smelled, vibrated, or made noise in the engine room. I’d encourage you to continue that. For the best possible installation, use rubber isolation mounts to prevent transferring that noise to the hull structure. It’s a minor detail, but it’s the accumulation of minor details like that make an Amel special. When running new cables from the battery to the engine room, you do not need to dig out the potting material used in the original wiring installation. Every SM I have worked on has had room to add wires into the engine room above the existing potting. Drill a hole in the bulkhead large enough for a short piece of pvc pipe just a bit larger in diameter than the wire, glue the pipe in place in the bulkhead, run the wire(s) through the pipe, and once done, fill the space around the wire with low expansion urethane foam. Fully water proof, and air tight. If the wires are large (which they likely will be) one hole per wire can be a better solution than one huge hole. That process sounds simple, and it is, but the limited space involved can require some unusual tools. Just as a bit of something to keep in mind: High Amperage DC wiring causes far more boat fires than propane. It should be done with good care and understanding of the issues involved. Shortcuts should not be taken. A Victron 3000 Watt inverter can easily draw 130 Amps, and are typically fused at 200A. The wiring and connections for that much current need to be done with care.

Re: Victron multiplus 2 24v/70/3000
Bertrand Quénot
Hi Steve,
We did the same before starting our circumnavigation as we wanted to get permanent 220V from all the outlets and use the kitchen devices (boiler, toaster, coffee machine) without turning the generator on. It didn’t work well at the beginning and we had a temperature alarm that stopped the Vitron after a while. We had a Victron certified guy on board in the West Indies and it appeared that the electrician who as installed it has forgotten to connect the temperature sensor with the batteries. Since then it worked well. We learned as well that we can use the Victron and the 30A charger together with no harm as the Victron alone is less powerful to load the batteries than the former 100A. Hope this could help Bertrand SV ANTINEA A53#43 Galapagos

Steve, I just changed my 2 Mastervolt chargers on my Amel 54 for 2 Victron 24/3000/70’s and digging out the material that runs from the engine room to the battery box was a bear, which had to be done to run 4/0 cables due to the inverter loads. No easy task, but I managed.

Re: Victron multiplus 2 24v/70/3000
Hi Steve Nice to see you guys recently got some good time out back home in Cape Town. You may still remember the spot where we placed our Victron Multiplus 2 24/70/3000 on SV Island Pearl II, ie we built a very useful Printer desk shelf in the wet locker (which we never used for clothes) and this same Inverter/Charger sat underneath that where it could breathe with good airflow, and from where the large battery cables were less than 1 meter long (max) direct to the rear of the main battery switches. We then placed the remote controller head height above the Dishwasher so never had to switch it under the printer table.. You do need an electrician for this as one also needs to loop a decent size AC cable between the main AC trip switch and the Multiplus. Our reason for this was to minimize the cable lengths for more efficient inverting and charging. Once we installed that we never used the two Dolphins again but simply left them in place. If you want to still use them as a backup then you need to wire them via the "B" Port on the Victron so they can only charge when shore power is connected, ie don't try to charge from the inverter loop! This worked so well for us with all the solar that we barely ever used the Genset anymore after this was set up. It took cruising to a whole new level, and we now have the same unit similarly fitted to our land RV. Best of luck with it. Colin ex 2001 SM - SV Island Pearl II Brisbane, Australia

Re: Dessalator 24v watermaker motor expected brush life? Anyone replace theirs?
I did have to replace them. I would have no clue how many hours were on the motor, but it began hesitating and faltering. At first, I just pulled the motor up to the cockpit and cleaned out the collection of dust from the brushes. A shot of brake cleaner helped it immensely but man was that a black, sooty mess to clean up!
That solved it for several weeks until I could get to St. Thomas where we found a hole-in-the-wqll alternator and starter motor shop who did the rebuild for us for about $200. The brushes were not specialmordered, but rather custom-filed and sanded from bigger ones. Happy with the results. Gary W. Former owner, SM209

Re: Maramu replacement autopilot drive motor
Dear Amel friends and friends, Thank you for your comments. We have decided to keep our original autopilot and to equip our Maramu with a Hydrovane. The fact that in the event of a lightning strike we are not at the mercy of hand controls and in this way have an extra emergency rudder. Made us decide to buy a hydrovane. Thanks again

Size PSY PSS shaftseal
Dear Amel friends, We want to use a PSY PSS shaft seal on our Amel Maramu within the driveline. The diameter of our stern tube is 55 millimeters. The PSY PSS shaft seal is available in the following sizes:
- Shaft 35mm 2" to 2-1/8" (50.80mm to 53.98mm)
- Shaft 35mm 2-1/4" to 2-3/8" (57.15mm to 60.33mm)
We have contacted several suppliers of the PSY PSS shaft seal, but all suppliers have a different opinion. Is there anyone in this nice forum who has also installed a PSY PSS shaft seal on his or her Maramu? If so what size. I look forward to your response.
