It is suited to off-grid installations, marine and vehicle applications, and backup power systems where a single, integrated unit is preferable to separate components. The 160A charger input and 32A transfer switch make it capable of handling substantial loads while managing battery charging from shore power or a generator.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4000VA continuous inverter output at 230V AC from a 12V DC battery bank.\u003c\/li\u003e\n  \u003cli\u003e160A built-in battery charger with adaptive charge algorithm to suit a range of battery chemistries including lead-acid and lithium.\u003c\/li\u003e\n  \u003cli\u003e32A AC transfer switch for switching between shore\/generator power and inverter output, with a transfer time of less than 20 milliseconds.\u003c\/li\u003e\n  \u003cli\u003ePowerControl function limits the load on a generator or shore supply by reducing charger current when AC loads are high.\u003c\/li\u003e\n  \u003cli\u003ePowerAssist function supplements shore or generator power with battery power during peak demand, allowing a smaller AC supply to handle larger loads.\u003c\/li\u003e\n  \u003cli\u003eTwo AC outputs: one with UPS functionality (no-break) and one that can be disconnected when running on battery to shed non-essential loads.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron VE.Bus for system integration, remote monitoring and configuration via GX devices and VictronConnect.\u003c\/li\u003e\n  \u003cli\u003eProgrammable relay for generator start\/stop or alarm signalling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus-II is the second generation of Victron's MultiPlus inverter charger range. Compared to the original MultiPlus, it adds a built-in current transformer for more accurate AC monitoring, an additional AC input for grid or generator connection management, and improved integration with Victron's GX ecosystem. The 12\/4000\/160-32 variant is the largest 12V model in the range, making it appropriate where a 12V battery bank is already specified but high inverter output and fast charging are required.\u003c\/p\u003e\n\n\u003cp\u003eThe 160A charger is significant in practice. At 12V, 160A equates to roughly 1920W of charging power, which allows a large battery bank to be recharged efficiently during generator run time. The adaptive four-stage charge algorithm (bulk, absorption, float, storage) helps extend battery life regardless of whether the bank is lead-acid AGM, gel or lithium iron phosphate. For lithium batteries, the unit must be configured correctly and used with a compatible BMS; Victron's own Smart Lithium batteries communicate directly via VE.Bus or a BMS interface.\u003c\/p\u003e\n\n\u003cp\u003ePowerAssist is particularly useful in installations where the available shore or generator supply is limited. If the AC input is set to, say, 16A and the connected loads briefly exceed that, the MultiPlus-II draws the shortfall from the battery rather than tripping the supply breaker. This allows a modest generator or marina shore connection to support loads that would otherwise require a larger supply. The sub-20ms transfer time means most sensitive electronics, including computers and medical equipment, continue operating without interruption when switching between AC input and inverter.\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;\"\u003ePMP122405010\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBattery Voltage\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e12V DC\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;\"\u003e4000VA \/ 3500W continuous\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 AC\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;\"\u003e160A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Transfer Switch Current\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e32A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Input Voltage Range\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e230V AC (single phase)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eTransfer Time\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u0026lt;20ms\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCommunication Interface\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eVE.Bus\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;\"\u003e23.4 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;\"\u003e8719076072058\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 cabins and remote buildings with 12V battery banks requiring 230V AC output.\u003c\/li\u003e\n  \u003cli\u003eMarine vessels with 12V DC systems needing shore power integration and battery charging.\u003c\/li\u003e\n  \u003cli\u003eLarge motorhomes and expedition vehicles where high charger current reduces generator run time.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems for critical loads requiring near-instantaneous transfer from mains to inverter.\u003c\/li\u003e\n  \u003cli\u003eHybrid off-grid systems paired with a Victron GX device, solar charge controllers and a generator.\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 MultiPlus-II 12\/4000\/160-32 230V inverter charger unit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus-II 12\/4000\/160-32 handles high DC currents at 12V and must be installed by a qualified electrician or accredited installer. DC cable sizing, fusing and connection torque are critical at this current level; undersized cabling presents a serious fire risk. For any grid-connected or export application in the UK, G98 or G99 compliance requirements apply and the installation must be notified to the relevant Distribution Network Operator. When used with lithium batteries, a compatible BMS must be in place before commissioning. Configuration is carried out via VEConfigure or VictronConnect and should not be altered without understanding the implications for the connected battery and load.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60190996201806,"sku":"PMP122405010","price":1051.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_PMP122405010_-_MultiPlus-II_12-4k-160-32_230V.webp?v=1784715764","url":"https:\/\/voltaconsolar.com\/products\/victron-multiplus-ii-12-4000-160-32-230v","provider":"VoltaconSolar","version":"1.0","type":"link"}
