The Victron MultiPlus-II 12V 3000VA Inverter Charger (PMP122305010) is one of the most capable all-in-one power solutions available for serious off-grid setups — delivering a continuous 2400W of pure sine wave AC output from a 12V battery bank, with a 120A battery charger built in. Its PowerAssist technology intelligently boosts available AC power during peak demand, so your generator or shore power connection is never overloaded. With a millisecond transfer switch, computers, CPAP machines, and other sensitive electronics stay running seamlessly when switching between mains and inverter power — a critical feature for full-time caravanners and remote work travellers.

Designed for Australian caravanners, RV owners, off-road tourers, and motorhome travellers who need reliable, high-capacity power management, the MultiPlus-II handles everything from running a residential air conditioner and microwave simultaneously to charging lithium and AGM battery banks at 120A while connected to a campsite power post. Its two AC outputs allow one circuit to remain live even when the charger trips — ideal for safety-critical loads like fridges. Whether you're parked at a powered site, running off solar, or hooked to a generator in the outback, the MultiPlus-II integrates seamlessly with Victron's GX ecosystem for full remote monitoring and control via the VRM portal.
