It accepts a wide AC input range of 120 to 240V, making it suitable for use across the UK, EU and North America.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThree independent output banks: one 20A main output and two 4A auxiliary outputs for simultaneous charging of multiple batteries.\u003c\/li\u003e\n  \u003cli\u003eWide AC input voltage range of 120 to 240V, compatible with single-phase mains supplies worldwide.\u003c\/li\u003e\n  \u003cli\u003eAutomatic four-stage charging algorithm: bulk, absorption, float and storage, optimised for lead-acid battery types including gel, AGM and flooded.\u003c\/li\u003e\n  \u003cli\u003eTemperature-compensated charging via optional sensor, adjusting charge voltage to battery temperature for accurate, safe charging.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled with adaptive charge management that remembers battery behaviour and adjusts absorption time accordingly.\u003c\/li\u003e\n  \u003cli\u003eFully sealed and vibration-resistant construction, suitable for marine, vehicle and industrial environments.\u003c\/li\u003e\n  \u003cli\u003eProtection against reverse polarity, short circuit, overheating and high AC voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Centaur range uses a transformer-based design rather than high-frequency switching, which gives it inherent resilience to voltage spikes and interference on the AC supply. This makes it a practical choice for installations where supply quality is variable, such as marinas, remote sites or generator-fed systems. The 12\/20 model delivers 20A to the primary battery bank, with two additional 4A outputs for starter batteries or secondary service banks.\u003c\/p\u003e\n\n\u003cp\u003eThe adaptive absorption algorithm is a practical feature for working installations. Rather than applying a fixed absorption time, the charger monitors how long bulk charging took and adjusts absorption accordingly. Batteries that are only partially discharged receive a shorter absorption phase, reducing unnecessary gassing and heat. Batteries that have been deeply discharged receive a longer absorption phase to ensure a full charge.\u003c\/p\u003e\n\n\u003cp\u003eThe storage mode reduces float voltage after 24 hours in float, minimising corrosion and water loss in flooded batteries during long periods of inactivity. This is particularly useful in seasonal or standby applications where the charger may be connected for weeks at a time.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CCH012020000\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 12V\u003c\/li\u003e\n  \u003cli\u003eMain output current: 20A\u003c\/li\u003e\n  \u003cli\u003eAuxiliary output current: 4A + 4A (two banks)\u003c\/li\u003e\n  \u003cli\u003eAC input voltage: 120 to 240V AC\u003c\/li\u003e\n  \u003cli\u003eWeight: 4.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076021476\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine vessels with main and auxiliary battery banks requiring simultaneous charging from shore power.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and coaches where a single charger must maintain both the leisure and starter batteries.\u003c\/li\u003e\n  \u003cli\u003eIndustrial and commercial standby systems with multiple lead-acid battery banks.\u003c\/li\u003e\n  \u003cli\u003eGenerator-fed off-grid sites where AC supply quality may be inconsistent.\u003c\/li\u003e\n  \u003cli\u003eSeasonal installations such as narrowboats or static caravans where long-term storage charging is required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVictron Centaur Charger 12\/20(3) 120-240V unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Centaur 12\/20 should be installed by a qualified electrician or competent marine\/vehicle electrician. Ensure the AC supply is correctly fused and that all DC output connections are appropriately rated for the cable run length and battery bank configuration. For marine installations, follow applicable NMEA or RCD Directive wiring standards. The unit is not suitable for lithium battery chemistries unless confirmed compatible by Victron documentation for the specific battery type.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60201799778638,"sku":"CCH012020000","price":281.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_CCH012020000_-_Centaur_Charger_12-20_3_120-240V.webp?v=1784819073","url":"https:\/\/voltaconsolar.com\/products\/victron-centaur-charger-12-20-three-output-120-240v","provider":"VoltaconSolar","version":"1.0","type":"link"}
