Victron Energy Orion-Tr Smart 48/48-8A (380W) Isolated DC-DC charger - ORI484838120

The Victron Energy Orion-Tr Smart 48/48-8A (380W) Isolated DC-DC Charger, manufacturer part number ORI484838120, is an intelligent, Bluetooth-enabled battery charger designed to charge a nominal 48V auxiliary or service battery from a separate 48V DC power source. Featuring galvanic isolation, adaptive three-stage battery charging, programmable output settings, and integrated electrical protection, this charger is ideal for off-grid power systems, marine applications, industrial installations, specialty vehicles, and other applications requiring controlled charging between separate 48V DC electrical systems.

Unlike DC-DC chargers designed to step voltage up or down between different nominal battery voltages, the Orion-Tr Smart 48/48-8A is engineered for applications where both the source and destination systems operate at a nominal 48V. Its isolated architecture allows the charger to regulate the charging voltage while maintaining electrical separation between the source and auxiliary battery circuits.

Important: The ORI484838120 is an isolated 48V-to-48V DC-DC battery charger. It is not an AC battery charger, DC-to-AC inverter, or solar MPPT charge controller. It is designed to charge a separate compatible battery system rather than directly parallel two battery banks.
