It is suited to professional installers working on campervans, boats, trucks and off-grid installations where a stable output voltage must be maintained regardless of fluctuations at the source.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e25A continuous output current with buck-boost topology, allowing the output voltage to be set higher, lower or equal to the input voltage.\u003c\/li\u003e\n  \u003cli\u003eNon-isolated design provides efficient power conversion without the losses associated with transformer-based isolation.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates varying battery or alternator voltages found in real-world vehicle and off-grid applications.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 1.03 kg, making it practical for installations with limited space.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron's VE.Direct communication interface for monitoring and configuration via Victron Connect or a GX device.\u003c\/li\u003e\n  \u003cli\u003eSuitable for 12V to 12V, 12V to 24V, 24V to 12V and 24V to 24V system configurations.\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 is either a buck (step-down) or boost (step-up) type, which means it only functions correctly when the input voltage is consistently above or below the output voltage. The buck-boost topology removes this constraint. The converter can regulate a stable output even when the input voltage crosses above and below the output voltage during operation, which is common in systems fed by a partially discharged battery or a variable alternator output.\u003c\/p\u003e\n\n\u003cp\u003eAt 25A, this unit is capable of handling meaningful charge currents for secondary battery banks. In a split-charge vehicle system, for example, it can charge a 12V leisure battery from a 12V starter circuit without the output being affected by engine-off voltage drop or engine-on alternator spikes. The non-isolated architecture means the negative terminals of input and output share a common reference, which must be accounted for during system design.\u003c\/p\u003e\n\n\u003cp\u003eIntegration with the Victron ecosystem is straightforward. The VE.Direct port allows connection to a GX device such as a Cerbo GX, enabling the converter to appear within the Venus OS dashboard alongside other system components. This is particularly useful in managed off-grid or marine installations where a full system overview is required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI303025000\u003c\/li\u003e\n  \u003cli\u003eOutput current: 25A\u003c\/li\u003e\n  \u003cli\u003eConverter type: Buck-Boost, non-isolated\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.03 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076035909\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a secondary leisure or auxiliary battery from a vehicle starter battery circuit.\u003c\/li\u003e\n  \u003cli\u003eMaintaining a stable 24V output from a 12V source, or vice versa, in mixed-voltage vehicle systems.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins and mobile installations where input voltage varies with battery state of charge.\u003c\/li\u003e\n  \u003cli\u003eMarine electrical systems requiring regulated DC supply to secondary battery banks.\u003c\/li\u003e\n  \u003cli\u003eTruck and commercial vehicle auxiliary power systems with variable alternator output.\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 25A Buck-Boost DC\/DC Converter\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 grounds are common; incorrect wiring in systems with multiple ground references can cause faults or damage. Ensure cable sizing and fusing are appropriate for 25A continuous DC current. For marine installations, follow applicable NMEA or RCD Directive wiring standards. Victron Connect (via VE.Direct USB adapter or Bluetooth if supported) should be used to configure input and output voltage parameters before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59866747601230,"sku":"ORI303025000","price":442.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI303025000_-_25A_Buck-Boost_DC-DC_converter.webp?v=1781200233","url":"https:\/\/voltaconsolar.com\/products\/victron-25a-buck-boost-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
