It accepts a 48V battery bank, delivers 4500VA of continuous AC output, and includes a built-in Venus OS GX device for monitoring and system control without requiring a separate Cerbo GX or Color Control unit. Suited to professional installers building residential or light commercial energy storage systems.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4500VA continuous inverter output at 230V AC, with a 9000W peak surge capacity to handle motor start loads.\u003c\/li\u003e\n  \u003cli\u003e55A battery charger with adaptive charge algorithm, suitable for lead-acid (AGM, gel, flooded) and lithium battery chemistries.\u003c\/li\u003e\n  \u003cli\u003e32A AC input current limit, adjustable via the GX interface or VEConfigure, allowing fine control over grid or generator input draw.\u003c\/li\u003e\n  \u003cli\u003eIntegrated GX controller running Venus OS, providing built-in system monitoring, VRM portal connectivity and DVCC support without additional hardware.\u003c\/li\u003e\n  \u003cli\u003ePowerControl and PowerAssist functions prevent overloading a limited AC source by supplementing grid or generator power with battery power when demand exceeds the input limit.\u003c\/li\u003e\n  \u003cli\u003eTransfer switch with a typical switchover time of 20ms, fast enough to maintain most sensitive loads during a grid outage.\u003c\/li\u003e\n  \u003cli\u003eSingle-phase unit; can be configured in parallel for higher power or in split-phase and three-phase systems using multiple units.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron VE.Bus communication for integration with MPPT solar charge controllers, BMV battery monitors and other VE.Bus or VE.Can devices.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus-II GX combines the functionality of the standard MultiPlus-II with an onboard GX device, removing the need for a separate Cerbo GX or CCGX in most installations. The Venus OS platform handles system monitoring, data logging to the VRM online portal, and communication between connected Victron devices. This simplifies wiring and reduces hardware costs on straightforward residential or small commercial battery storage projects.\u003c\/p\u003e\n\n\u003cp\u003eThe 55A charger uses Victron's adaptive charging algorithm, which adjusts the charge curve based on battery behaviour rather than applying a fixed profile. This extends battery life across a range of chemistries. The PowerAssist function is particularly useful where the AC input is constrained, such as a small generator or a weak grid connection: the inverter draws the maximum permitted current from the source and supplements any additional load demand from the battery, keeping the generator or supply within its rated capacity.\u003c\/p\u003e\n\n\u003cp\u003eThe 48V battery voltage is the standard choice for systems above 2kW, as it keeps DC cable currents manageable at higher power levels. At 4500VA output, the DC current draw at full load is approximately 100A at 48V, which is practical to wire safely with standard DC cabling. The unit weighs 21.91kg and requires a fixed, ventilated mounting location with appropriate DC fusing and AC isolation in accordance with BS 7671 and any applicable DNO requirements.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24;

DC connections at 48V with high-capacity battery banks carry significant fault current and require correctly rated fusing, cabling and isolation. For grid-connected installations in the UK, compliance with G98 or G99 (depending on export capacity and DNO requirements) must be confirmed before commissioning. The integrated GX device requires a network connection (Ethernet or Wi-Fi) for VRM portal access. Ensure adequate ventilation around the unit; do not install in an enclosed, unventilated space. Lithium battery integration requires correct DVCC configuration via the GX interface.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59855398535502,"sku":"PMP482406000","price":658.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_PMP482406000_-_MultiPlus-II_48-4k5-55-32_230V_GX.webp?v=1781094320","url":"https:\/\/voltaconsolar.com\/products\/victron-multiplus-ii-48-4500-55-32-230v-gx","provider":"VoltaconSolar","version":"1.0","type":"link"}
