It is suited to off-grid installations, marine and vehicle applications, and backup power systems where reliable DC-to-AC conversion and mains charging are both required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e3000VA continuous inverter output at 230V AC from a 12V DC battery bank.\u003c\/li\u003e\n  \u003cli\u003e120A battery charger built in, with adaptive charge algorithm to suit a range of battery chemistries including flooded, AGM and gel.\u003c\/li\u003e\n  \u003cli\u003e50A AC passthrough allows shore power or generator input to supply connected loads directly while simultaneously charging the battery.\u003c\/li\u003e\n  \u003cli\u003ePowerControl and PowerAssist functions prevent overloading a limited AC source by supplementing it with battery power when demand exceeds supply.\u003c\/li\u003e\n  \u003cli\u003eVE.Bus communication interface enables system integration, parallel operation and three-phase configuration with compatible Victron equipment.\u003c\/li\u003e\n  \u003cli\u003eTransfer switch with a typical switchover time of 20 milliseconds, fast enough for most computers and sensitive electronics.\u003c\/li\u003e\n  \u003cli\u003eProgrammable relay and two-signal BMS connection support for lithium battery systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus combines a true sine wave inverter with a multi-stage battery charger. In inverter mode, it converts 12V DC from a battery bank into 230V AC at 3000VA continuous output. The built-in 120A charger uses an adaptive algorithm that adjusts the charge profile based on battery behaviour, which helps extend battery service life across different chemistries. The 50A AC input passthrough means that when a mains or generator supply is available, loads are fed directly from that source while the charger tops up the batteries.\u003c\/p\u003e\n\n\u003cp\u003ePowerAssist is a particularly practical feature for installations where the available AC source is limited, such as a shore power connection with a fixed amperage limit or a small generator. When load demand exceeds what the AC source can supply, the MultiPlus draws the deficit from the battery bank rather than tripping the supply. This allows a smaller, more economical generator to be used without risk of overload.\u003c\/p\u003e\n\n\u003cp\u003eVE.Bus connectivity allows multiple MultiPlus units to be configured in parallel for increased current capacity, or in split-phase and three-phase arrangements. The interface also supports integration with Victron system monitoring and control products, including the Color Control GX and Venus GX. Configuration and firmware updates are handled via the VE.Bus interface using Victron's VEConfigure software.\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  \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  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003ePMP123021010\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eDC Input Voltage (Nominal)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e12V\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;\"\u003e3000VA\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 Output\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 (Passthrough)\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 Output Waveform\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eTrue sine wave\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;\"\u003e18.85 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;\"\u003e8719076023951\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOff-grid cabins, lodges and remote buildings requiring 230V AC power from a 12V battery bank.\u003c\/li\u003e\n  \u003cli\u003eMarine vessels with 12V DC systems needing shore power integration and onboard AC supply.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes, coaches and large campervans with high AC load requirements.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems for critical equipment where fast transfer from mains to battery is required.\u003c\/li\u003e\n  \u003cli\u003eGenerator-assisted off-grid systems where PowerAssist reduces the required generator size.\u003c\/li\u003e\n  \u003cli\u003eParallel or three-phase Victron system builds using VE.Bus for expanded capacity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron MultiPlus 12\/3000\/120-50 230V VE.Bus 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 12\/3000\/120-50 handles significant DC current at 12V and must be installed by a qualified electrician or accredited installer.
