Combining a robust 230V pure sine wave inverter with a powerful adaptive battery charger, this unit features Energy Storage System (ESS) capabilities, allowing seamless integration with solar, grid-tied, and generator systems for intelligent energy management. Delivering continuous output of 4 kW and peak power of 7 kW, it ensures reliable operation for critical loads even during high-demand periods. The integrated 55 A charger rapidly replenishes your battery bank, minimising generator run time and maximising solar utilisation.\u003c\/p\u003e \u003ch3\u003ePowerControl \u0026amp; PowerAssist – Intelligent Energy Management\u003c\/h3\u003e \u003cp\u003eThe MultiPlus-II’s PowerControl feature allows precise limitation of AC input current, preventing overload on generators or the grid. PowerAssist extends this functionality by supplementing limited grid or generator power with stored battery energy during peak loads, then recharging the battery once demand decreases. This maximises system efficiency and guarantees uninterrupted power to essential loads, making it ideal for sites with limited shore power or generator capacity.\u003c\/p\u003e \u003ch3\u003eSeamless AC Supply \u0026amp; Dual Output Functionality\u003c\/h3\u003e \u003cp\u003eThe main AC output delivers uninterrupted power during grid or generator outages, with transfer times under 20 milliseconds, keeping sensitive electronics operational. The secondary AC output is live only when input power is present, ideal for non-critical loads such as water heaters. Both outputs integrate with PowerControl and PowerAssist for smart load management, ensuring critical loads always have priority.\u003c\/p\u003e \u003ch3\u003eScalable \u0026amp; Flexible System Configuration\u003c\/h3\u003e \u003cp\u003eUp to six MultiPlus-II units can be connected in parallel for expanded power capacity. Three units of the same model can be configured for three-phase output, and up to six sets of three units can operate in parallel for very large installations. On-site configuration is simple via VEConfigure software, while real-time monitoring is available through Cerbo GX, Ekrano GX, Digital Multi Control Panel, VictronConnect, or the VRM Online portal.\u003c\/p\u003e \u003ch3\u003eHigh Efficiency \u0026amp; Robust Design\u003c\/h3\u003e \u003cp\u003eWith a maximum efficiency of 95%, the MultiPlus-II minimises energy losses while delivering reliable AC power. Its rugged IP21-rated steel enclosure and fan-assisted cooling allow safe operation in temperatures from -40°C to +65°C. Compatible with lithium, lead-acid, and zinc-bromine batteries, it provides flexibility for diverse energy storage systems. The internal transfer switch is rated at 32 A, ensuring safe passage of grid or generator power.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003ePure sine wave inverter with 4 kW continuous output and 7 kW peak power\u003c\/li\u003e \u003cli\u003ePowerful 55 A adaptive battery charger for rapid recharging\u003c\/li\u003e \u003cli\u003ePowerControl and PowerAssist prevent AC input overload and supplement limited sources\u003c\/li\u003e \u003cli\u003eUltra-fast \u0026lt;20 ms transfer switch for uninterrupted UPS-grade backup power\u003c\/li\u003e \u003cli\u003eParallel and three-phase capable for scalable system design\u003c\/li\u003e \u003cli\u003eWide -40°C to +65°C operating temperature range with fan-assisted cooling\u003c\/li\u003e \u003cli\u003eCompatible with lithium, lead-acid, and zinc-bromine battery chemistries\u003c\/li\u003e \u003cli\u003eIntegrated ESS functionality for advanced solar and grid energy management\u003c\/li\u003e \u003cli\u003eRemote monitoring and control via VictronConnect, VRM portal, or GX device\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eApplications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eMarine and yachting systems requiring uninterrupted AC power\u003c\/li\u003e \u003cli\u003eMobile vehicles and off-grid installations\u003c\/li\u003e \u003cli\u003eResidential and commercial solar + battery setups\u003c\/li\u003e \u003cli\u003eHigh-demand off-grid energy storage and backup power\u003c\/li\u003e \u003cli\u003eCritical load support in professional energy systems\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eEquip your installation with the Victron MultiPlus-II for advanced energy management, high-efficiency AC power, and seamless support for critical loads in demanding off-grid, mobile, and professional environments. \u003cstrong\u003eOrder your Victron MultiPlus-II inverter\/charger today and take control of your energy independence.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Victron","offers":[{"title":"Default Title","offer_id":55056003793235,"sku":"VIC-PMP482405012","price":622.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1076\/9324\/4755\/files\/victron-multiplus-ii-48v-4500w-inverter-vic-pmp482405012.jpg?v=1790333791","url":"https:\/\/progradewarehouse.com\/products\/victron-multiplus-ii-48-4k5-55-32-230v","provider":"PRO GRADE WAREHOUSE","version":"1.0","type":"link"}
