12v boat system charged with Multiplus and DC-DC charger to 24V thruster

Hi!

we have a 12v 3*230Ah house battery that is charged with a 120A Multi and an alternator. We are looking to eliminate a separate 24v charger that is used for a bow thruster. We are looking into the new Orion-Tr Smart DC-DC Charger Isolated with 12V in and 24V out.

The assumption is that we can set it voltages so that either the alternator or the multi would provide a voltage level for the DC-DC to start charging the 24V system. Is there any reason why such design should be avoided? (The difference between stanard use case is that we also want to charge when the Multi is connected and only when the alternator is running) and we also assume that the on the 12v side it would not influence that charging process and any way.

Hi @eliott

Yes that works, please use the 'demo library' in Victron Connect to see what settings you can use.

and also see the datasheet, is there anything this doesn't answer?
