It is suited to small off-grid installations, marine and vehicle applications, and backup power setups where space and weight are at a premium.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e500VA inverter output with a 12V DC input, providing 230V AC output for small loads.\u003c\/li\u003e\n  \u003cli\u003e20A battery charger built in, allowing the unit to charge the battery bank when AC input is available.\u003c\/li\u003e\n  \u003cli\u003e16A AC transfer switch for passing shore or generator power through to connected loads.\u003c\/li\u003e\n  \u003cli\u003eVE.Bus communication interface for system integration, parallel operation and remote monitoring via Victron GX devices.\u003c\/li\u003e\n  \u003cli\u003ePowerAssist function supplements AC input with inverter power to prevent overloading a limited shore or generator supply.\u003c\/li\u003e\n  \u003cli\u003eAdaptive battery charging algorithm with automatic charge curve selection to suit different battery chemistries.\u003c\/li\u003e\n  \u003cli\u003eNear-instant transfer switching (less than 20ms) to maintain supply to connected equipment during mains failure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlus 12\/500\/20-16 combines a sine wave inverter, a multi-stage battery charger and an AC transfer switch in a single unit. When AC input is present from shore power or a generator, the unit passes that power through to the AC output and simultaneously charges the battery at up to 20A. When AC input is lost or disconnected, the unit switches to inverter mode in under 20ms, maintaining supply to connected loads without interruption.\u003c\/p\u003e\n\n\u003cp\u003eThe VE.Bus interface is a key practical feature for installers. It allows multiple MultiPlus units to be configured in parallel for increased capacity, or in split-phase and three-phase arrangements. It also enables full integration with Victron GX devices such as the Cerbo GX, giving access to remote monitoring, system configuration and data logging through the VRM portal. Configuration is carried out using Victron's VEConfigure software via a VE.Bus to USB interface.\u003c\/p\u003e\n\n\u003cp\u003ePowerAssist is particularly useful in installations where the available AC input is limited, such as a small generator or a restricted shore power connection. The unit monitors the AC input current and, when loads approach the input limit, supplements the supply with power drawn from the battery via the inverter. This prevents nuisance tripping of the input supply without requiring a larger generator or shore connection.\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;\"\u003ePMP121500000\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;\"\u003eInverter Output\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e500VA\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;\"\u003eBattery Charger Output\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e20A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Transfer Switch\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e16A\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;\"\u003e5.5 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;\"\u003e8719076046363\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\u003eSmall off-grid cabins, sheds or outbuildings with a 12V battery bank.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring a combined inverter and charger in a compact form factor.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and campervans needing 230V AC output from a 12V leisure battery system.\u003c\/li\u003e\n  \u003cli\u003eBackup power for critical small loads such as communications equipment or lighting.\u003c\/li\u003e\n  \u003cli\u003eInstallations requiring integration into a larger Victron VE.Bus system with GX monitoring.\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\/500\/20-16 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\u003eInstallation should be carried out by a qualified electrician or experienced system integrator. DC wiring at 12V with a 500VA inverter involves high currents and must be correctly fused and sized. For any connection to a shore power supply or generator, all AC wiring must comply with current UK wiring regulations (BS 7671). Configuration of the unit requires Victron's VEConfigure software and a VE.Bus to USB interface cable, sold separately.
