It is suited to off-grid installations, marine and vehicle applications, and small backup power systems 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 at 230V AC from a 12V DC battery bank, with a continuous power rating suitable for small loads and essential circuits.\u003c\/li\u003e\n  \u003cli\u003e20A battery charger built in, with adaptive charge technology that adjusts the charge curve based on battery behaviour over time.\u003c\/li\u003e\n  \u003cli\u003e16A AC transfer switch allows connection to shore power or a generator, automatically switching between mains input and inverter output.\u003c\/li\u003e\n  \u003cli\u003eVE.Bus communication interface enables system integration, remote monitoring and configuration via Victron GX devices and VEConfigure software.\u003c\/li\u003e\n  \u003cli\u003ePowerControl function limits the load on a generator or shore supply by reducing charge current when AC loads are high, preventing overload.\u003c\/li\u003e\n  \u003cli\u003ePowerAssist function supplements the AC input with inverter power during peak demand, allowing use of a smaller generator or limited shore supply.\u003c\/li\u003e\n  \u003cli\u003eSupports lithium-ion and lead-acid battery chemistries, with configurable charge parameters to suit different battery types.\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 automatic transfer switch into one unit. When AC input is available (shore power or generator), the unit charges the battery bank and passes power through to connected loads. When AC input is lost or disconnected, it switches to inverter mode in under 20 milliseconds, which is fast enough to keep most sensitive equipment running without interruption.\u003c\/p\u003e\n\n\u003cp\u003eThe 20A charger uses Victron's adaptive charge algorithm, which builds a profile of the battery over its first charge cycles and adjusts accordingly. This is particularly useful in installations where battery condition or history is unknown. The PowerControl and PowerAssist features are relevant where the available AC supply is limited, for example on a small generator or a marina berth with a restricted amperage allowance. Rather than tripping the supply, the unit reduces or supplements current draw automatically.\u003c\/p\u003e\n\n\u003cp\u003eVE.Bus connectivity means the MultiPlus 12\/500\/20-16 can be configured remotely and integrated into a wider Victron system including MPPT solar charge controllers, GX monitoring devices and the VRM online portal. For standalone use, it can also be configured directly via the VEConfigure software over 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; 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;\"\u003ePMP121500000\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;\"\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 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;\"\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 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;\"\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\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOff-grid cabins and small remote installations with a 12V battery bank and limited AC load requirements.\u003c\/li\u003e\n  \u003cli\u003eMarine vessels requiring shore power integration and battery charging with automatic switchover.\u003c\/li\u003e\n  \u003cli\u003eCampervans, motorhomes and vehicle conversions where 230V AC output from a 12V system is needed.\u003c\/li\u003e\n  \u003cli\u003eSmall UPS (uninterruptible power supply) applications for sensitive equipment in commercial or residential settings.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems paired with solar charge controllers and a GX monitoring device.\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 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 accredited installer familiar with DC battery systems and 230V AC wiring. The unit must be connected to an appropriately rated 12V battery bank with correctly sized DC cabling and fusing. For any grid-connected or shore-power applications, wiring must comply with current UK wiring regulations (BS 7671). VE.Bus configuration requires Victron's VEConfigure software and a compatible interface cable. Lithium battery installations may require additional BMS integration and charge parameter configuration before commissioning.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59855393227086,"sku":"PMP121500000","price":252.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_PMP121500000_-_MultiPlus_12-500-20-16_230V_VE.Bus.webp?v=1781094311","url":"https:\/\/voltaconsolar.com\/products\/victron-multiplus-12-500-20-16-230v-ve-bus","provider":"VoltaconSolar","version":"1.0","type":"link"}
