The Victron Energy Buck-Boost 50A DC-DC Converter (ORI303050000) from Nomadic Supply Company® is a programmable converter designed to step up or step down DC voltages for charging auxiliary batteries from vehicle alternators.
The Victron Energy Buck-Boost 50A DC-DC Converter (ORI303050000) is a DC-DC Converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. Since, when the engine is running, these dynamos (powered by the onboard electronics of Euro 5 and 6 engines) do not always emit the correct charging current, a DC-DC converter is essential for charging the service battery properly.
Nomadic Supply Company prefers the Victron Energy Buck-Boost 50A DC-DC Converter (ORI303050000) over the Victron Energy Orion-TR 12|12-30 DC-DC Converter Isolated (ORI121240110) because they can be stacked together for more amperage, and they don’t get hot like the Victron Energy Orion-Tr tend to. However, the Buck-Boosts do require a Windows computer for programming which is a huge downside and is why we use the Victron Energy Orion-TR 12|12-30 DC-DC Converter Isolated (ORI121240110) in our Electrical Kits. If you’re like most people and don’t have a Windows computer, then you’ll want to use the Victron Energy Orion-TR 12|12-30 DC-DC Converter Isolated (ORI121240110) since they come with Bluetooth which makes the programming a lot easier; no computer needed. Just make sure when installing a Victron Energy Orion-TR 12|12-30 DC-DC Converter Isolated (ORI121240110) that you have plenty of ventilation to let the heat disperse.
