The 120A charger output is substantial for a 12V unit, making it practical where fast battery recovery is a priority, such as after a generator run or when connected to shore power with limited availability. The adaptive charge algorithm adjusts charge parameters based on battery behaviour over time, which is particularly useful in installations where the battery bank is not always fully discharged before recharging.\u003c\/p\u003e\n\n\u003cp\u003ePowerAssist is one of the more practically useful features for installations with a constrained AC source. When the connected load exceeds what the shore power or generator can supply alone, the unit draws the deficit from the battery bank rather than tripping the source breaker. This is especially relevant on boats, in campervans, or in off-grid cabins where the generator or shore supply has a fixed current limit. The 32A input current limit on this model is configurable, giving the installer control over how much of the source capacity is reserved for charging versus load supply.\u003c\/p\u003e\n\n\u003cp\u003eThe dual AC output configuration adds practical load management without additional switching hardware. AC-out-1 is always live when the unit is operational, while AC-out-2 drops out when the inverter is running on battery alone. This allows non-essential loads such as water heaters or air conditioning to be wired to AC-out-2, reducing battery drain automatically without any manual intervention.\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;\"\u003ePMP122305010\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 \/ 2400W\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;\"\u003e12V\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 Current Limit\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 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;\"\u003eAC Outputs\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e2 (AC-out-1 always live; AC-out-2 disconnects on inverter)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eTransfer Switch Time\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eLess than 20ms (typical)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCommunication\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;\"\u003e20.5 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;\"\u003e8719076048916\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 properties requiring reliable AC power from a 12V battery bank.\u003c\/li\u003e\n  \u003cli\u003eMarine installations where shore power is supplemented by battery during peak demand.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and large campervans with significant AC load requirements.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems for critical equipment where fast transfer and continuous AC-out-1 supply is required.\u003c\/li\u003e\n  \u003cli\u003eHybrid off-grid systems paired with solar charge controllers and a GX monitoring device.\u003c\/li\u003e\n  \u003cli\u003eParallel or three-phase configurations where multiple MultiPlus-II units are combined for higher output.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron MultiPlus-II 12\/3000\/120-32 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\/3000\/120-32 handles high DC currents at 12V and must be installed by a qualified electrician or accredited installer. Cable sizing, fusing and battery connections must be rated appropriately for the current involved.
