Re: Shore - Generator Switch-over box on A54 #solution

Hi Reudi;
I agree. I was just trying to point out that this chaining of inverter/charger approach has the possibility of almost matching the generator output with units that are manageable in size and weight. Also, the inversion is not the only advantage. By having a potential 300A charging capability, a large portion of the load of the bowthruster can be removed from the batteries. Also, it provides redundancy for both the chargers and inverters, as one of these units could provide sufficient capability, until a defective unit can be replaced. They can all be monitored and configured through the MV Bluetooth and panel.
As others have pointed out, on our 54 #099, we have a vertical plywood bulkhead that the inverter and the 100A charger is mounted on. The inverter/charger is only slightly taller than the original inverter and I was able to install vertically with slight modifications to the mounting channel on the new inverter/charger.
Happy Sailing;

Hello Mohammad
This is a lot of Inverting power. You probably not need that much unless you want to run everything simultaneously in the boat 😉 Nevertheless, I ordered the MV MassCombiPro 24/3500W since I have already 2 Solar controllers separately and do not need in the same box. Queston: Did you installed the MV Mass Combi Ultra 24/3500 at the same place/pedestal where the 2500W inverter was? Or you found another place? - I’m asking because the installation manual says it should be installed vertical and the existing A54 inverter pedestal is somehow more horizontal then vertical. I guess you use it as 2500W inverter replacement and not for charging? So probably no issue with the ventilation so far?
Thanks for advice and best regards Ruedi Waldispuehl WASABI A54. #55 Currently in Gibraltar

Hello Ian;
My knowledge of the LN175 and Dolphin charger is limited, so I will not be of much help there. I can share with you our current approach for our charging and inversion plans, as we make the necessary upgrades, as equipment fails.
Our 2500W Mastervolt inverter failed at the end of the 2019 season. We would like to use the existing charger wiring in the engine room. We have replaced our inverter with a MV Mass Combi Ultra 24/3500. These inverter /chargers can charge at 100A, provide 3500W 220V and have solar controllers built in. They can also be connected in series for additional charging and inversion output. We intend to have 2 in series, giving us 200A charging/7000 W inversion. We will still have our existing 40A MV charger, for a total of 240A charging. I have not checked the existing 40A charging wiring size. It is possible to add a third combi Ultra for max of 300A charging and 10,500W of inversion. The Combi Ultra can also be programmed to limit the charge/inversion output to match the wiring size. The plan is to be able to supply the entire 220V panel from the inverters.
We have not gone far down the design phase, as this is some time away for us. However, I like the small size (same appx footprint as the inverter we replaced) and light weight of combi/ultra. We should be able to fit 2 and possibly three in the same footprint and location of the existing chargers. Minimal wiring and full integration, monitoring and control of the Lithium batteries, chargers, inverters and solar.
All of this is very preliminary. In the next 2-3 years that it will take for us to be ready to make the upgrade, I’m sure may thing have changed that will require changes to our basic design concept.

Mohammad,
Thank you for your insights on Lithium. We are in a similar situation and agree that Lithium is too early for us.
Will really appreciate your guidance on best solutions for changes to LN175 alternator (and Dolphin 100A Charger) when upgrading to 8AGM 105Ahr on AMEL54 #009.
