Victron MultiPlus-II 12/3000/120-50 2x120V

The Victron MultiPlus-II 12/3000/120-50 2x120V is an industry-leading, multifunctional power hub engineered specifically for high-efficiency 12V marine, RV, campervan, and mobile 50A electrical systems. By combining a powerful pure sine wave inverter, an advanced adaptive battery charger, and a lightning-fast AC transfer switch into a single compact housing, it simplifies complex power configurations while delivering uncompromised efficiency. With complete North American UL 458 mobile safety listings, this specialized 2x120V AC unit is built to manage heavy-duty 50-amp split-phase shore power cords or dual-leg generator connections, providing uncompromised protection when distributing power across your entire breaker panel. Key Features & Capabilities Intelligent PowerAssist Technology: Eliminates the risk of tripping weak shore power breakers or stalling small generators. When system demand spikes beyond the AC source limit, the MultiPlus-II instantly dials back its own battery charging and supplements the shortfall by pulling power from your battery bank. True UPS Functionality (No-Break Switchover): Features an integrated 50A high-speed automatic transfer switch. If the grid fails or shore power is pulled, the internal inverter takes over the electrical loads in under 20 milliseconds, ensuring computers and sensitive electronics run uninterrupted. Optimized 12V Adaptive Charging: The built-in 120A charger utilizes an intelligent four-stage process (Bulk, Absorption, Float, and Storage) that adapts to your battery bank's daily behavior. It is fully pre-programmed to handle premium AGM, lead-acid, and modern Lithium-Ion (LiFePO4) setups. Seamless 2x120V Split-Phase Integration: Built uniquely for North American 50A applications. When hooked to 120/240V shore power, it passes both 120V legs (L1 and L2) right through to your panel. When running off the 12V battery bank, it connects both legs internally so your entire coach has 120V power from a single unit (Note: it does not create 240V standalone). Unmatched System Scalability: Up to six MultiPlus-II units can be wired in parallel to scale up total continuous output wattage and charge capacity. Units can also be configured to support true split-phase (120/240V) or three-phase configurations.
