It combines a high-quality \u003cstrong\u003epure sine wave inverter\u003c\/strong\u003e with an advanced \u003cstrong\u003ebattery charger\u003c\/strong\u003e and an integrated \u003cstrong\u003eAC transfer switch\u003c\/strong\u003e, giving you a compact, single-unit solution for \u003cstrong\u003ecaravans\u003c\/strong\u003e, \u003cstrong\u003e4WD touring\u003c\/strong\u003e, \u003cstrong\u003emarine\u003c\/strong\u003e installations, \u003cstrong\u003eoff-grid solar\u003c\/strong\u003e and \u003cstrong\u003ebackup power\u003c\/strong\u003e in homes, sheds and remote sites.\u003c\/p\u003e\n\u003cp\u003eIn practical terms, it helps turn your 12V battery bank into consistent \u003cstrong\u003e230V AC\u003c\/strong\u003e for everyday appliances and sensitive electronics, while also charging your batteries correctly when shore power, grid or a generator is available. This is especially useful in real-world setups where AC supply can be limited or inconsistent (crowded caravan parks, long extension leads, small generators, or sites with fluctuating loads).\u003c\/p\u003e\n\u003ch3\u003ePowerControl and PowerAssist: manage limited AC supply without constant load juggling\u003c\/h3\u003e\n\u003cp\u003eUnlike basic inverter chargers that either pass-through or shut down under pressure, this unit supports \u003cstrong\u003ePowerControl\u003c\/strong\u003e to limit incoming AC current and reduce nuisance trips on weak supplies. When a load briefly demands more than the available mains or generator can provide, \u003cstrong\u003ePowerAssist\u003c\/strong\u003e can supplement that shortfall from the battery. The benefit is smoother operation of higher-start appliances and tools in caravan parks and generator-powered setups where supply headroom is tight.\u003c\/p\u003e\n\u003ch3\u003eFast transfer switching for continuity on essential circuits\u003c\/h3\u003e\n\u003cp\u003eWhen external AC drops out, the inverter can take over quickly to help keep selected circuits running. This makes it a strong fit for UPS-style resilience in home and off-grid backup systems, such as comms, networking, refrigeration, medical support loads, control systems, and other equipment that benefits from continuity and stable voltage.\u003c\/p\u003e\n\u003ch3\u003eCharging designed to suit modern battery systems\u003c\/h3\u003e\n\u003cp\u003eBattery charging is where many generic inverter chargers fall short—especially with lithium batteries. The integrated charger supports configurable charge profiles for \u003cstrong\u003eLiFePO4\u003c\/strong\u003e and lead-acid batteries, helping you align charging behaviour with battery manufacturer recommendations. Support for battery temperature sensing improves charge accuracy as conditions change, reducing unnecessary stress on batteries and improving day-to-day performance for mobile and off-grid power systems.\u003c\/p\u003e\n\u003ch3\u003eDual AC outputs to prioritise critical vs non-critical loads\u003c\/h3\u003e\n\u003cp\u003eWith \u003cstrong\u003etwo AC outputs\u003c\/strong\u003e, you can separate critical loads (that you want backed up by the inverter) from non-essential loads (that should run only when external AC is present). This is a practical way to protect runtime overnight, prevent accidental battery depletion, and keep the most important circuits operating during outages or when running from battery-only.\u003c\/p\u003e\n\u003ch3\u003eMonitoring and system integration ready\u003c\/h3\u003e\n\u003cp\u003eFor installers and technically-minded users, VE.Bus communication enables deeper configuration, system integration and compatibility with Victron monitoring ecosystems such as \u003cstrong\u003eVRM\u003c\/strong\u003e (when used with a compatible GX device). This helps with commissioning, remote oversight, alarms, and automation options like generator start\/stop via a programmable relay to suit your site requirements.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInverter + charger + transfer switching in one unit\u003c\/strong\u003e to simplify system design and wiring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePure sine wave 230V output\u003c\/strong\u003e for stable operation of sensitive electronics and appliances\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowerControl \u0026amp; PowerAssist\u003c\/strong\u003e to help manage limited grid\/generator supply and support short peak loads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast changeover\u003c\/strong\u003e to help maintain continuity for essential circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual AC outputs\u003c\/strong\u003e for prioritised critical vs non-critical load control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfigurable charging\u003c\/strong\u003e to suit lithium and lead-acid battery systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePeak power\u003c\/strong\u003e capability helps cover short start-up surges from motor loads and compressors, while the \u003cstrong\u003e160A\u003c\/strong\u003e charger supports faster recovery when you’re back on mains or generator—particularly valuable after overnight use or during poor solar conditions. As with any inverter\/charger installation, performance depends on correct cable sizing, battery capability, ventilation and protective devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReady to build a more capable caravan, marine or off-grid power system?\u003c\/strong\u003e Add this Victron inverter\/charger to your setup for clean 230V power, intelligent charging, and better control of limited AC supplies—ideal for touring, marine reliability, off-grid living, or resilient backup circuits\u003c\/p\u003e\n\u003cp\u003eSupports parallel and three-phase operation via VE.Bus for scalable AC systems and higher capacity installations\u003c\/p\u003e","brand":"Victron","offers":[{"title":"Default Title","offer_id":43109033967677,"sku":"VIC-PMP122405010","price":2199.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0602\/3918\/3933\/files\/victron-multiplus-ii-12v-4000w-front-view-vic-pmp122405010.jpg?v=1778827281","url":"https:\/\/www.solar4rvs.com.au\/products\/victron-12v-4000va-multiplus-ii-12-4000-160-32-inverter-charger","provider":"Solar 4 RVs","version":"1.0","type":"link"}
