{"product_id":"qbp770811","title":"Victron Energy MultiPlus 2000VA Inverter\/Charger, 120V, VE.Bus","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Victron Energy MultiPlus 2000VA 120V is an inverter\/charger for marine AC power systems that combines a true sine wave inverter, adaptive battery charging, and a 50 A AC transfer switch in one unit. It supplies 120 VAC at 60 Hz, delivers 2000 VA of inverter output, and supports 12 V, 24 V, or 48 V DC battery banks depending on the selected variant.\u003c\/p\u003e\u003cp\u003eOn board, it is used between the battery bank and the vessel AC loads, with shore power or generator input feeding the charger and transfer switch. PowerControl and PowerAssist help manage limited dockside or generator power by reducing battery charging when AC loads rise, then supplementing the AC source from the batteries when extra power is needed for short periods.\u003c\/p\u003e\u003cp\u003eThe enclosure is steel with an IP22 rating, so it belongs in a dry, protected equipment space with enough airflow for fan assisted cooling. It is a strong fit for cruising boats, fishing boats, and workboats that need one unit to handle inverter output, battery charging, and fast AC transfer when shore or generator power changes.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eTrue sine wave inverter output for sensitive onboard electronics and standard 120 VAC loads.\u003c\/li\u003e\n\u003cli\u003e2000 VA continuous inverter rating, with 1600 W continuous output at 25°C and 3500 W peak power.\u003c\/li\u003e\n\u003cli\u003e50 A transfer switch for moving between inverter power and an available shore power or generator source.\u003c\/li\u003e\n\u003cli\u003ePowerControl and PowerAssist help prevent overload when dock power or generator capacity is limited.\u003c\/li\u003e\n\u003cli\u003eAdaptive four stage charging supports the house battery bank, with a 1 A starter battery charge output on the 12 V and 24 V models.\u003c\/li\u003e\n\u003cli\u003eVE.Bus communication port supports parallel operation, three phase operation, remote monitoring, and broader Victron system integration.\u003c\/li\u003e\n\u003cli\u003eCompatible with GX monitoring hardware for local and remote system visibility through the Victron ecosystem.\u003c\/li\u003e\n\u003cli\u003eBattery temperature sensor support helps charging respond to real battery conditions.\u003c\/li\u003e\n\u003cli\u003eSteel enclosure rated IP22, with M8 battery connections and screw terminals for AC wiring.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis MultiPlus 2000VA 120V range is offered in three configurations for different DC battery system voltages. The main selection points are the vessel battery bank voltage and the matching house battery charge current.\u003c\/p\u003e\u003cp\u003eAll three versions share the same 120 VAC output format, 2000 VA inverter class, 50 A transfer switch, VE.Bus communication, steel IP22 enclosure, and 506 x 236 x 147 mm housing. The DC input range, charge current, efficiency, and low-load consumption change with the battery voltage version.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePMP122200100: 12 V DC system voltage with 80 A battery charge current. This version matches boats built around a 12 V house bank and gives the highest charger output in the range.\u003c\/li\u003e\n\u003cli\u003ePMP242200100: 24 V DC system voltage with 50 A battery charge current. This version suits vessels using a 24 V house bank, a common setup for larger DC loads and longer cable runs.\u003c\/li\u003e\n\u003cli\u003ePMP482200100: 48 V DC system voltage with 25 A battery charge current. This version fits 48 V battery systems where lower DC current can help with cable sizing and system efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe unit should be installed where it is protected from spray, washdown water, salt mist, and direct bilge moisture. The IP22 enclosure is intended for sheltered electrical spaces, not exposed cockpit, deck, or engine room locations where water can reach the unit directly.\u003c\/p\u003e\u003cp\u003eBattery cables, AC cabling, overcurrent protection, ventilation, and grounding should be planned around the selected DC voltage and the boat electrical standards used for the installation. The product does not include an internal DC fuse, so external DC protection must be handled in the system design.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThe inverter output is 120 VAC with 60 Hz frequency, and the charger accepts 95 to 140 VAC input. The VE.Bus port allows the MultiPlus to be part of a larger Victron power system, including remote control, monitoring, and configuration through compatible Victron accessories.\u003c\/p\u003e\u003cp\u003eFor boats with limited shore power, the PowerAssist function is especially useful at marinas with smaller pedestals or when running from a generator. It helps keep AC loads moving without forcing the generator or shore connection to carry every short peak by itself.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis inverter\/charger is well suited for running everyday AC loads from the battery bank while away from the dock, then recharging the bank when shore power or a generator is available. Typical onboard uses include cabin outlets, galley equipment within the inverter rating, navigation electronics support, battery charging, and AC power continuity during source changes.\u003c\/p\u003e\u003cp\u003eThe less than 20 millisecond transfer behavior helps keep many connected electronics powered when shore or generator input is lost, although final equipment suitability always depends on the full vessel wiring layout and the sensitivity of the connected loads.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"12 V \/ 80 A","offer_id":52581993513141,"sku":"QBP770811-V1","price":10.35,"currency_code":"USD","in_stock":false},{"title":"24 V \/ 50 A","offer_id":52581993545909,"sku":"QBP770811-V2","price":0.0,"currency_code":"USD","in_stock":false},{"title":"48 V \/ 25 A","offer_id":52581993578677,"sku":"QBP770811-V3","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1336317_qbp770811.jpg?v=1780202219","url":"https:\/\/www.qualityboatparts.com\/products\/qbp770811","provider":"Quality Boat Parts","version":"1.0","type":"link"}
