It is suited to dual-battery systems, vehicle-to-load charging, and any installation where the input and output voltages may be higher, lower or equal to one another.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e100A continuous output current, suitable for high-demand DC loads and battery charging applications.\u003c\/li\u003e\n  \u003cli\u003eBuck-boost topology allows the output voltage to be set higher, lower or equal to the input voltage, unlike a simple buck or boost converter.\u003c\/li\u003e\n  \u003cli\u003eNon-isolated design provides efficient power conversion with minimal heat loss compared to transformer-based alternatives.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron's VE.Direct communication interface for monitoring and configuration via GX devices or VictronConnect.\u003c\/li\u003e\n  \u003cli\u003eSuitable for 12V and 24V system architectures, covering the most common mobile and off-grid voltage configurations.\u003c\/li\u003e\n  \u003cli\u003eCompact and robust aluminium housing with a weight of 4.1 kg, appropriate for permanent installation in vehicles, vessels and fixed off-grid enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eA standard DC-DC converter can only step voltage in one direction. A buck-boost converter removes that constraint: the output can be regulated to a fixed target regardless of whether the input is above or below it. This matters in real installations where input voltage fluctuates, for example when a starter battery drops under load or a lithium auxiliary battery sits at a higher resting voltage than a lead-acid bank.\u003c\/p\u003e\n\n\u003cp\u003eAt 100A, this unit is capable of handling substantial charging currents for auxiliary battery banks or supplying high-current DC loads directly. The non-isolated topology means the negative rails are shared between input and output, which is standard practice in most vehicle and marine wiring schemes. Installers should confirm this is compatible with the earthing arrangement of the specific installation before proceeding.\u003c\/p\u003e\n\n\u003cp\u003eIntegration with the Victron ecosystem is straightforward via VE.Direct. When connected to a GX device such as a Cerbo GX, the converter appears in the system overview and can be monitored alongside other Victron components. Configuration and firmware updates are handled through the VictronConnect app.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI303100000\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076046837\u003c\/li\u003e\n  \u003cli\u003eOutput current: 100A\u003c\/li\u003e\n  \u003cli\u003eConverter type: Buck-Boost, non-isolated\u003c\/li\u003e\n  \u003cli\u003eWeight: 4.1 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-battery charging in campervans, motorhomes and HGVs, where the auxiliary bank must be charged from the alternator without overcharging or undercharging.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring a regulated DC supply to a secondary battery bank from a main house bank at a different voltage.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile power systems where input voltage varies with state of charge and a stable output is required.\u003c\/li\u003e\n  \u003cli\u003eVehicle-mounted equipment requiring a fixed DC voltage independent of the chassis battery state.\u003c\/li\u003e\n  \u003cli\u003eRenewable energy systems combining solar and alternator input sources with mixed battery chemistries at different nominal voltages.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Energy 100A Buck-Boost DC\/DC Converter (ORI303100000)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation should be carried out by a qualified electrician or experienced system integrator familiar with DC power systems. The non-isolated design means input and output negative terminals are common; verify this is appropriate for the earthing scheme of the vessel or vehicle before wiring. For marine installations, follow applicable NMEA or flag-state wiring standards. Ensure adequate ventilation or heatsinking for the rated current. Fuse both input and output cables as close to the source as practicable and in accordance with the cable ratings used.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59845811896654,"sku":"ORI303100000","price":963.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI303100000_-_100A_Buck-Boost_DC-DC_converter.webp?v=1781019893","url":"https:\/\/voltaconsolar.com\/products\/victron-100a-buck-boost-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
