Sailing Yacht Wiring Diagram on Victron components

Hello everyone. I am trying to redesign the wiring diagram on my yacht. The attached image shows the current wiring diagram and the new one I want to implement. I'm not a specialist and I don't know what I'm doing. May I ask your help with design of new wiring diagram or at least to comment my one? Even on commercial basis. I would be sincerely grateful for any comments and additions. I also have open questions:

1. Are manual switches needed and where?
2. Victron has a battery protector and a battery monitor. Should they be included as well? I don’t quite understand how to integrate them into the current three-battery circuit
3. Can the ArgoDiod/ArgoFET battery separator really charge AGM and Lead-Acid batteries at the same time? They have different input charging voltage and capacitance.
4. Due to the fact that there is a power controller and a combiner, the circuit looks like it is possible to put a house battery of different capacities, or is it completely nonsense?
5. From the ArgoDiod/ArgoFET power controller, in which MPPT connector of the solar battery charger should the wires be inserted - into LOAD or still Battery?
6. Should I connect only starter battery to engine's starter?
7. Should I somehow set up the alternator?

Many thanks in advice!

Hi @yatsukav

I'm also not a professional, probably worth checking all of this with one however:

1. Yes I would add them in as many places as possible. Especially for safe maintenance in the future. ie PV -> Disconnect -> charge controller -> disconnect. If you're using centralised bus bars I've also have a disconnect before the battery and before the load. just incase you want to remove or add anything to any sections of the system in the future.

Similarly I've also add fuses between everything also to protect wires/system in the event of a fault.


2. I imagine you will need some form of battery monitoring device to know useful information about the battery such as State of charge, voltage, current in/out (to know if you're charing/discharing or if there's any issues with the system). And also to help not overcharge or deplete the battery too much


3-7 Sorry I'm not too sure re AGM/lead acids batteries I use LiFePO4. I know for LiFePO4 you need a DC-DC charger if you're using an alternator as the alternator will burn out otherwise.

Not sure what if anything is needed for AGM/lead acids.

You might want to increase the PV power.

100W is not that much even for a DC-only (no inverter) system.
