Thank you Thomas. I’ll review and am sure will have some questions.


Happy Sailing;

Mohammad, Arno,


In the message 


I described the implementation of the MasterVolt MassCombi Pro 24V/3500W/100A on Garulfo (amongst other things)


Hope it helps,



Note that we have a dessalator duo100 (24V and 220V), so we can run it directly on the batteries. The overall unit is about 900W, so we could also use the 220V side through the inverter, say if the 24V side was faulty and didn’t want to run the genset. If your watermater 150L/h is 220V only and uses 3kW, you’ll need to take that into consideration for your inverter choice.

Hi Scott,

On my A54 the cables for the chargers (Mastervolt 100 A and 40 A) are routed individually to the batteries. They are actually connected on the primary side of the big red switches (so connected to the battery side). Pretty sure they did this to make sure the charger "knows" the exact battery voltage and to enable charging with the red switches off (when the boat is decommissioned for example) . The junction in the engine room is only supplying the gray fuse box as far as I can see. This is also where the inverter gets it power from (via a circuit breaker). I did not investigate where this 95mm2 feed cable is exactly going to. That is not so easy, hence my question on this forum. At the back of the red switches there is a plethora of cables going in all directions, the markings are not easy to read. There are also two studs distributing the power as well.
