Hello, for a boat, I'm searching for a way to use a 48V system (used for propulsion) to charge 12V batteries used for house loads.
- The charging device needs to have isolation between the 48V and 12V legs
- The charging device needs to have programmable charging parameters for the 12V batteries (battleborn LFP)
The Orion-Tr series of converters are not smart and just output a steady voltage, since they are converters only, so they won't work for this use case
The Orion Smart charger/converters only support 12V/24V and not 48V.
I could use a MPPT solar charge controller but I'm not sure that they are actually isolated.
I do see the "SmartSolar MPPT RS 450|100 & 450|200 - Isolated" but I think it is overkill, and too big for the space available for the device.
Any ideas of a victron product that would work? Are the usual victron solar charge controllers isolated?
