Victron MultiPlus-II 12V 4000VA Inverter Charger
Mains power anywhere: It converts your 12V battery power into a steady 230V supply, allowing you to use household appliances like coffee machines and laptops away from the grid.
No more power cuts: In the event of a grid failure or shore power disconnection, the unit takes over in less than 20 milliseconds, keeping your sensitive electronics running without a flicker.
Boost your supply: If your shore power or generator is limited, the unit can use battery power to assist the supply, allowing you to run high-demand equipment that would otherwise trip a breaker.
Super-fast charging: The integrated 160A charger uses a smart algorithm to recharge your batteries quickly and safely, helping to extend their overall lifespan.
Silent and efficient: Designed for high efficiency, the unit works quietly in the background to provide power without wasting precious battery energy.
Ready for the future: This model is fully compatible with modern lithium batteries and can be integrated into solar energy storage systems for even greater independence.

Product Details
The PMP122405010 is a 12V model within the renowned MultiPlus-II range, specifically designed to provide 4000VA of continuous output power. As a multifunctional inverter charger, it features two AC outputs. The main output provides the uninterruptible power supply (UPS) function, while the second auxiliary output only operates when AC is available on the input, which is ideal for heavy loads that you do not wish to run from your battery, such as water heaters.
Safety and reliability are at the core of this design. The unit features built-in protection against short circuits, overloads and battery voltage issues. It is housed in a rugged steel enclosure with a blue RAL 5012 finish, rated to IP21 for protection. At 22kg, it is a substantial piece of equipment built for long-term use in demanding environments like marine engine rooms or vehicle lockers.
One of the most powerful features for the modern user is the ability to monitor and control the system remotely. When paired with a GX device such as the Cerbo GX, you can check your system status or adjust settings from anywhere in the world using your phone or laptop. If your power needs grow, the MultiPlus-II is ready to scale, supporting parallel and three-phase configurations to provide virtually unlimited power output. With its high peak power of 8000W, it can easily handle the initial surge required by motors or power tools that would stall lesser inverters.
