Hello
Trying to get to grips with a solar arch and lithium upgrade but also trying to understand the boat electrics. I do not have MasterVolt but have ChargeMaster 12/70-3 and Victron MultiPlus 12/300/120 and my boat, Saoirse (hull #065 from 2010) is 110v.
So a shore power question as I am in Greece/ EU with 220v - as I understand my system, when I plug to shore power, AC flows to my ChargeMaster to my batters AND not AC shore power direct to AC systems.
Am I missing something ? Are there any other components hidden on the boat that I should be aware of that might be impacting the AC flow ?
Thanks

Not sure I can help, others please confirm, but on my 2019, 220V boat, the flow is from my understanding…shore power…charger…batteries. All AC runs off your batteries through the inverters. But not sure what you mean by “impacting my AC flow”
First I would like to confirm which MultiPlus you have I’m assuming it’s a 12/3000/120 and that it is configured as an inverter only.
The charge master (Mastervolt) is a battery charger that will take a wide range of input voltages anything from about 95 to 265v so it doesn’t care where in the world it is plugged in.
So it looks to me like your boat is set up in a similar fashion to mine - with all mains power aboard coming from the inverter and only the battery charger having to deal with the variety of shore power voltages and frequencies. In my opinion it’s a great setup for voyaging boats.
We recently did a complete rebuild of our electrics to Victron, I’m on my phone at the moment but when I get to the laptop I’ll add the layout schematic.
With a Victron based lithium system you effectively pick which BMS you will use and work from there with batteries and gizmo’s that allow charging or stop discharge to protect the lithium.
Controlling the Mastervolt Chargemaster will be one area to consider.
