s/v Jedi Electrical Management System

The AC- and DC systems are not complete without system management. This does not include the BMS which I keep with the battery itself.

Some notes:

We have four VE-Direct devices but only three ports. This is handled by converting one to USB.

We have two Multiplus units but do not want the Victron setup where they operate in parallel. This means we can not interconnect them with the Cerbo GX via VE-Bus. We fix this by only connecting one with VE-Bus and converting the other one to USB and connect that to the Cerbo GX. This does allow management of the Multiplus and it's operational numbers are included in the totals on screen.

I specified the Multiplus II units because they support an external current sensor. This allows the unit to see total power draw from shore power or genset, incl. that of the other Multiplus as well as the ByPass circuit. This allows for correct operation of Power Control and Power Assist.
