It is suited to off-grid installations, backup power systems, and solar energy storage applications where a single, integrated unit is required to manage both charging and inversion. The 32A transfer switch allows it to accept input from a generator or grid supply and switch to inverter mode when that source is unavailable.\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 from a 48V DC battery bank.\u003c\/li\u003e\n  \u003cli\u003e55A battery charger built in, with adaptive charge algorithm to suit a range of battery chemistries.\u003c\/li\u003e\n  \u003cli\u003e32A AC input current rating, suitable for connection to a generator or grid supply.\u003c\/li\u003e\n  \u003cli\u003ePowerAssist function supplements the AC input when load demand exceeds the available supply current.\u003c\/li\u003e\n  \u003cli\u003eTransfer switch with a typical switchover time of less than 20 milliseconds, maintaining supply to connected loads during source transitions.\u003c\/li\u003e\n  \u003cli\u003eTwo AC outputs: AC-Out-1 remains live during inverter operation; AC-Out-2 is disconnected when running on battery, allowing non-critical loads to be shed automatically.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron VE.Bus for system integration, remote monitoring and parallel or three-phase configuration.\u003c\/li\u003e\n  \u003cli\u003eSupports ESS (Energy Storage System) configuration when used with compatible Victron equipment and a GX device.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus-II combines a sine wave inverter, a multi-stage battery charger and an automatic transfer switch in a single enclosure. The 48V input voltage is well suited to larger battery banks where lower current draw reduces cable losses and heat generation compared to 12V or 24V equivalents. At 4500VA, the unit can handle substantial loads including motor start-up surges, which typically require two to three times the running wattage.\u003c\/p\u003e\n\n\u003cp\u003eThe PowerAssist feature is particularly useful where the available AC input is limited, for example when running from a small generator. The MultiPlus-II draws what the generator can supply and supplements the remainder from the battery, allowing loads to run that would otherwise overload the source. This also means a smaller, more fuel-efficient generator can be used alongside a battery bank without load-shedding.\u003c\/p\u003e\n\n\u003cp\u003eVE.Bus connectivity allows multiple units to be configured in parallel for increased capacity, or in split-phase and three-phase arrangements. When paired with a Victron GX device (such as a Cerbo GX), the unit can be integrated into an ESS configuration for grid-tied or hybrid solar storage systems. Configuration and firmware updates are handled via VEConfigure software using a VE.Bus to USB interface.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24;

For grid-connected ESS applications in the UK, the installation must comply with G98 or G99 requirements depending on export capacity, and the installer should hold appropriate MCS or equivalent accreditation. Battery connections must be correctly fused and sized for the current involved. VE.Bus configuration requires Victron's VEConfigure software and a compatible interface cable. The unit is not suitable for direct connection to a lithium battery without a compatible BMS and correct charge parameter configuration.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59855393358158,"sku":"PMP482405012","price":559.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_PMP482405012_-_MultiPlus-II_48-4k5-55-32_230V.webp?v=1781094315","url":"https:\/\/voltaconsolar.com\/products\/victron-multiplus-ii-48v-4500va-55a-inverter-charger-230v","provider":"VoltaconSolar","version":"1.0","type":"link"}
