Dear customer service, I would like to inform, if I connect a 12V lead batteries from Fiat Ducato 2020 (120A alternator), with a 24V lifepo4 battery 2x200A power system. Will be the Victron Orion-TR 12/24-30 isolated the best option? The 24V system is not grounded to the body of the vehicle
Theres unfortunately no 12/24 30A option, if you want one with bluetooth you could aim for the Orion-Tr Smart 12/24-15A Isolated DC-DC charger (ORI122436120).
Im running the 12/12-30 which is the equivalent to the 12/24-15 but for 12V in a RV with perfect results.
In Netherlands there is option to buy the Victron Orion-TR 12/24-30 isolated: https://www.bluepowershop.nl/victron-omvormer-orion-tr-smart-24-12-30a-360w-met-galvanische-scheiding.html . But these Orion-TR 12/24-15A or 12/24 30A options will be fits in my system right? Thank you
You must use 12/24 models.
To get a higher current, use multiple Orions in parallel.
It will be part of the installation to have a common ground between the vehicle battery and 24V system.
Be careful you don't overload the alternator. Try to stay below 50% of it's rated output when you add the Orion load to the existing loads. 15A at 24V is 30A at 12V. Add in lights, computer, fuel pump etc.
Thank you for your response, so if I understand correctly: when I have a 120A alternator combined with 24V system, and if I will use 2x Orion-Tr Smart 12/24-15A-Isolated installed in parallel, I will be at 30A, so Im still on the safety side.
