The Victron MultiPlus-II 12/3000 - 120-50 - 120V represents the pinnacle of marine power management technology, combining a high-performance 3000W pure sine wave inverter with a sophisticated 120A battery charger and 50A transfer switch in one UL Listed unit. This advanced inverter/charger system delivers uninterrupted power for your vessel's critical electronics while providing intelligent battery charging and shore power integration.
The MultiPlus-II intelligently manages limited AC power sources like shore power or generator connections. When demand exceeds available shore power, the system automatically supplements with battery power, preventing circuit breakers from tripping while maximizing available power for your vessel's needs.
Critical for marine electronics, the sub-20 millisecond transfer time ensures navigation systems, chartplotters, VHF radios, and other essential equipment continue operating during shore power disconnections or generator startup sequences.
Integrates seamlessly with Victron MPPT solar charge controllers and GX monitoring devices to create comprehensive energy management systems. Perfect for vessels with solar arrays seeking to maximize self-sufficiency and minimize generator runtime.
Optional external current transformer (max 32A) enables advanced PowerControl and PowerAssist functions with precise load monitoring for optimal power distribution throughout your vessel's electrical system.
The Victron MultiPlus-II is backed by Victron Energy's comprehensive 5-year warranty and worldwide network of authorized service centers. Technical support is available through certified marine dealers with access to VE.Configure software and diagnostic tools.
Important: All returns, repairs, and support issues must be handled through your authorized Victron dealer to maintain warranty coverage and ensure proper marine electrical system integration.
A: Victron recommends a minimum 400Ah battery bank at 12V for optimal performance. Larger battery banks provide longer runtime and reduce stress on the batteries during high-load situations.
A: Yes, up to 6 units can be connected in parallel using VE.Bus cables for increased power capacity, or configured in 3-phase arrangements for specialized applications.
A: Absolutely. The MultiPlus-II includes pre-programmed charging profiles for LiFePO4 batteries and can be custom-configured for specific lithium battery management system requirements.
A: This single 120V version provides one 120V output suitable for 30A shore power connections. The 2x120V version provides split-phase 120/240V output for 50A shore power applications.
A: Yes, use marine-grade tinned copper conductors sized according to ABYC E-11 standards. DC connections require proper marine battery switches and overcurrent protection.
A: Yes, when connected to a Victron GX device with internet connectivity, you can monitor and control the system remotely via the free VRM portal and mobile app.
MultiPlus-II 12/3000 - 120-50 - 120V - UL Approved
The MultiPlus-II, an inverter/charger, combines the functions of the MultiPlus and the MultiGrid. It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
PowerAssist
The MultiPlus-II will prevent the overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shoreside supply with power taken from the battery.
ESS: Energy Storage Systems
The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters.
Uninterrupted AC power (UPS function)
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
Remote Monitoring and Control
When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backup generator and more.
