It accepts two independent AC inputs, making it suited to installations where both a generator and a shore or grid supply need to be managed automatically. This unit is aimed at professional installers working on off-grid, marine, vehicle and backup power systems.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e5000VA continuous inverter output at 230V AC from a 24V DC battery bank.\u003c\/li\u003e\n  \u003cli\u003e120A multi-stage battery charger built in, supporting bulk, absorption and float charging.\u003c\/li\u003e\n  \u003cli\u003eTwo independent AC inputs (50A each) with automatic transfer switching between grid and generator supplies.\u003c\/li\u003e\n  \u003cli\u003ePowerControl and PowerAssist functions limit the load on the AC input and supplement it with battery power when demand exceeds the available supply.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron VE.Bus communication for system integration, remote monitoring and parallel or three-phase configuration.\u003c\/li\u003e\n  \u003cli\u003eSupports parallel operation (up to six units) and split-phase or three-phase setups for larger installations.\u003c\/li\u003e\n  \u003cli\u003eProgrammable relay outputs and configurable charge parameters via VEConfigure software.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Quattro-II replaces the original Quattro range and shares the same core architecture while offering updated internal components. The dual AC input is one of its defining characteristics: the unit monitors both inputs and switches automatically to whichever is available, with no break in output. This is particularly useful on sites where a generator is the backup to a grid connection, or on vessels where shore power and a generator are both present.\u003c\/p\u003e\n\n\u003cp\u003eThe 120A charger is sized to handle large battery banks typical of 24V off-grid and backup installations. Charge parameters are fully adjustable, and the unit supports lithium battery profiles alongside lead-acid chemistries. PowerAssist allows the inverter to supplement an undersized AC supply rather than trip it, which is valuable when a generator or shore connection has a lower current rating than the connected loads demand.\u003c\/p\u003e\n\n\u003cp\u003eVE.Bus connectivity enables the Quattro-II to be integrated into a Victron system alongside MPPT solar charge controllers, a Cerbo GX monitoring unit and other VE.Bus devices. Multiple units can be configured in parallel to increase output capacity, or in three-phase arrangements for commercial and industrial applications.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eQUA242505010\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eInverter Output Power\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e5000VA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eDC Input Voltage\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e24V\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Output Voltage\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e230V\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBattery Charger Current\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e120A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Input 1 Current Rating\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e50A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Input 2 Current Rating\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e50A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Inputs\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e2 (independent)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e31 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076052920\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOff-grid residential and commercial installations with 24V battery banks requiring high-capacity inverter and charging capability.\u003c\/li\u003e\n  \u003cli\u003eMarine vessels with both shore power and generator connections requiring automatic source switching.\u003c\/li\u003e\n  \u003cli\u003eVehicle and mobile applications (large coaches, expedition vehicles) where dual AC input management is needed.\u003c\/li\u003e\n  \u003cli\u003eCritical backup power systems where uninterrupted transfer between grid and generator is required.\u003c\/li\u003e\n  \u003cli\u003eMulti-unit parallel or three-phase installations for higher output capacity in commercial settings.\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 Quattro-II 24\/5000\/120-50\/50 230V inverter charger unit\u003c\/li\u003e\n  \u003cli\u003eDocumentation and quick-start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Quattro-II must be installed by a qualified electrician familiar with inverter charger systems. At 31 kg, two-person handling is advisable during mounting. DC cabling must be rated for the high currents involved in a 24V\/5000VA system and kept as short as practicable to minimise voltage drop. Battery connections must be fused appropriately. For any grid-connected or generator-connected installation in the UK, compliance with current wiring regulations (BS 7671) and relevant network operator requirements is the installer's responsibility. Lithium battery installations require correct charge profile configuration via VEConfigure before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47392021545294,"sku":"QUA242505010","price":1395.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-quattro-ii-245000120-5050-230v-qua242505010-647335.jpg?v=1747927588","url":"https:\/\/voltaconsolar.com\/products\/victron-quattro-ii-24-5000-120-inverter-charger","provider":"VoltaconSolar","version":"1.0","type":"link"}
