This intelligent Victron Orion Smart isolated battery charger is designed to automatically charge one 12V battery / battery bank from another 12V battery / battery bank with its own energy source. For example, if one 12V battery / bank is being regularly charged by solar / mains/ alternator (incluing newer smart alternators), this 30A DC-to-DC battery charger can pull energy from this battery bank to charge a second 12V battery such as a liesure battery bank. The target battery / bank will be charged at a maximum of 30A, using an intelligent multi-stage approach with full overcharge protection.
 
The Orion Smart charger can also operate in a DC conversion mode, where the output voltage will be adjusted to a stable voltage with minimal electrical noise. This allows the running of sensitive DC equipment from a battery or other DC power source which may change voltage during charging or use.
