Beschreibung
MultiPlus-II 12/4k/160-32 230V
The MultiPlus-II is a multifunctional inverter/charger with two AC outputs. Suitable for professional marine, yacht, vehicle and land-based off-grid systems, it also provides the isolation and redundancy required for ESS configurations. With PowerControl, the MultiPlus-II prevents overloading of the grid or generator, while PowerAssist increases AC power during peak loads. In the event of a power failure, the inverter switches over within milliseconds so that computers and sensitive electronic devices remain in operation without interruption. The battery charger combines speed with efficiency through an intelligent adaptive algorithm that extends battery life. The MultiPlus-II is expandable and supports parallel and three-phase configurations when a system needs to be scaled.
PowerAssist
The MultiPlus-II prevents a limited AC source, such as a generator or shore power connection, from being overloaded. First, the battery charge is automatically reduced to protect against overload. Next, the output of a generator or shore power supply is boosted with energy from the battery.
ESS: Energy storage systems
The MultiPlus-II is a key component in a Victron ESS. It is very flexible and can be combined with an MPPT solar charger or a grid feed-in inverter for PV systems. Examples and further information can be found in the ESS (Energy Storage System) manual.
Uninterruptible alternating current (UPS function)
In the event of a grid fault or if the shore power or on-board generator is interrupted, the Multis inverter is automatically switched on and takes over the supply to the connected loads. The switchover happens so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed.
Remote monitoring and control
In conjunction with a GX device (e.g. Cerbo GX), you can use the free VRM app and Free VRM Portal website to monitor and control your Multi and the system or systems locally (LAN) or remotely via the Internet from anywhere in the world. Access can be via a phone, tablet, laptop or PC with a wide range of operating systems. There is no end to the control options, from setting up your Multi to automatically starting a backup generator and more..."

Victron MultiPlus-II 12/4k/160-32: The power pack for your 12V system
Don't want to compromise on your mobile freedom? Do you have a large 12V battery bank (ideally lithium) and want the same comfort on board or in the camper as at home? Coffee machine, hairdryer or even a small air conditioning unit - and all without blowing the fuse at the campsite?
The Victron MultiPlus-II 12/4k/160-32 is the technological answer for anyone who wants to get the most out of their 12V infrastructure. It combines a highly efficient 4000 VA inverter with a powerful 160A battery charger. It is not a simple accessory, but the intelligent energy center that decides whether you are just "camping" or truly self-sufficient.
Victron MultiPlus-II 12/4k: The advantages at a glance
- Superior 12V power: With 3400 watts of continuous power (4000 VA), you can supply even the most demanding 230V consumers directly from your 12V battery.
- Ultra-fast charging: The integrated 160 A charger refills even the most massive lithium banks in record time as soon as shore power or a generator is available.
- Intelligent mains support: Thanks to PowerAssist, the device "borrows" missing power from the battery if the shore power connection is too weakly fused.
- Seamless UPS function: In the event of a mains failure, the inverter takes over in less than 20 ms. Your IT and sensitive electronics continue to run without restarting.
- Maximum flexibility: Two AC outputs make it possible to automatically shed unimportant loads during battery operation in order to conserve your reserves.
More than just an inverter: The 4 core competencies of the MultiPlus-II 12/4k/160-32
The Victron MultiPlus-II 12/4k/160-32 is a highly specialized 4-in-1 combination device that revolutionizes your energy management. At Verkauf-Bochum.de, we rely on this model when 12V systems reach their performance limits.
- The superior inverter: It converts the 12V of your battery into an absolutely pure sine wave. With 3400W continuous power and 6000W peak load, you can start compressors and engines with ease.
- The high-performance charger: 160 amps of charging current is an announcement. This is ideal for modern LiFePO4 storage systems that can draw high currents. You spend less time on the cable and more time in freedom.
- The lightning-fast transfer switch: The integrated UPS function ensures that you won't even notice a power failure on the shore power. The switchover is so fast that no device switches off.
- The PowerAssist booster: A real problem on many pitches is the weak fuse protection (often only 4 A or 6 A). The MultiPlus-II 12/4k recognizes this and boosts the missing current from the battery. So you can still use your coffee machine.
Why the 12/4k is the heart of your professional van or boat
In the 12V world, this model is the "big boy". While other devices run hot or switch off at high loads, the new design of the MultiPlus-II offers significantly better operating behavior at high temperatures.
The advantage of integration:
Instead of installing a charger and an inverter separately, you have everything in one compact, vertical housing. This not only saves valuable space in the camper or engine room, but also massively reduces the amount of cabling required. The Victron ecosystem (e.g. with a Cerbo GX) gives you full control via smartphone - worldwide.

The physics of 12V high power: why planning is the key to safety here
In social networks and forums, there is often the dangerous opinion that a system of this power class can be realized by simply plugging components together. However, 4,000 VA power at a system voltage of just 12 volts means discharge currents of over 330 amps in practice.
For comparison: this is a current that is normally only known for a few seconds when starting a massive truck diesel engine - but the MultiPlus-II 12/4k delivers this energy continuously.
⚠️ Anyone who relies on standard components or "drop-in" batteries without system communication is being grossly negligent.
At such current levels, every ohm of additional resistance leads to massive heat development. A MultiPlus-II 12/4k/160-32 is a technical precision instrument that will only work safely if the entire environment is designed for these loads. A "blind" system without active data exchange between the inverter and battery will inevitably lead to premature wear of the cells or thermal failure of fuse elements.
These three technical pillars are essential for a reliable installation:
- The communication center (GX instance): Although a system controller such as the Victron Cerbo GX is optional for this system, it is our urgent recommendation for really clean and safe operation. It serves as an information hub: only with it do you have full control and can see all the power, voltages and currents as well as the exact remaining capacity of your battery in real time. This gives you the certainty that your system is always operating in the optimum range.
- Certified storage hardware with CAN bus interface: As this MultiPlus was specially developed for mobile applications (campers, boats), choosing the right battery is crucial. Here we rely on first-class components that are designed for high discharge currents (e.g. Victron lithium batteries). The important thing is that the battery capacity must be large enough to deliver the 4000 VA power in a stable manner. In combination with precise capacity monitoring that communicates with the Cerbo, you ensure that your energy storage system is never overloaded.
- Calculated line infrastructure: With 160 A charging current and over 300 A load current, the correct dimensioning of the DC cabling is elementary. We are talking about massive cross-sections and professional crimping to industry standards. With these amp loads, any improper connection is a potential source of fire.
We at Verkauf-Bochum.de do not see ourselves as mere sellers of hardware boxes. We are technicians who plan your entire system. We calculate the necessary cross-sections, select the appropriate protection devices and program the control units so that your system does what it is supposed to do: deliver maximum power - with maximum safety.
For whom is the Victron MultiPlus-II 12/4k/160-32 the right choice?
This device is the premium solution for anyone who does not want to convert their 12V on-board system to 24 V but still needs high performance.
- High-end expedition vehicles: You have 400 Ah+ lithium on board and want induction cooking? This is your device.
- Sailing & motor yachts: Perfect for managing shore power and generator while maintaining high comfort requirements.
- Compact off-grid cabins: Ideal for small 12V island systems with few but powerful consumers.
MultiPlus-II 12/4k/160-32 at Verkauf-Bochum.de: Superior system integration instead of just buying hardware
A high-current system with 160 A charging power and 4,000 VA inverter power is not a field for experiments. In 12V technology, millimetres in cable cross-section and milliohms in contact resistance determine the thermal stability of your entire system.
At Verkauf-Bochum.de, we do not define ourselves purely by trading in boxes. We see ourselves as your technical planning partner. We plan your DC busbars, calculate the physically necessary cable cross-sections for your specific cable lengths and take over the exact programming of the charging parameters for your lithium storage systems (e.g. Victron Energy). The result is a system that not only exists on paper, but also guarantees maximum operational reliability in reality.
FAQ - Frequently asked questions about the Victron MultiPlus-II 12/4k/160-32
Do I need special cables for 160 A charging current?
Definitely yes. With these currents, massive cable cross-sections (usually 2x 570mm² or more, depending on the length) are absolutely essential. We plan this precisely for you so that nothing gets hot.
Can I connect the device to a Cerbo GX?
Yes, absolutely. Via the VE.Bus, the MultiPlus 2 becomes part of your smart home on wheels. You can then monitor and control it via the GX Touch 50 or worldwide via the VRM portal.
Is a normal 100 Ah battery sufficient for this device?
No, that would be undersized. To make sensible use of the 4,000 VA output and the 160 A charging current, we recommend a lithium capacity of at least 300 Ah to 400 Ah, preferably more.
What does "VA vs. watt" mean?
Victron specifies the apparent power in VA. The actual active power (continuous power) for this device is 3,400 watts at an ambient temperature of 25 °C. This is the value you should expect for your devices.
