MultiPlus 48/20K/250-100
A MultiPlus, plus ESS (Energy Storage System) function
The MultiPlus-Il is a multifunctional inverter/charger with all the functions of the MultiPlus and an additional function, namely that of an external current sensor. This extends the PowerControl and PowerAssist functions to 50 A and 100 A respectively. The MultiPlus-Il is ideally suited for professional seafaring, yachts, vehicles and land-based, off-grid applications. It also has an integrated function to protect against islanding. Several different system configurations are possible. Further information can be found in the ESS Design & Configuration manual.
PowerControl and PowerAssist - increasing grid or generator power
A maximum grid or generator current can be set. The MultiPlus-Il then takes other AC loads into account and only uses the current that is still "left over" to charge the battery. This prevents the generator or mains connection from being overloaded (PowerControl function).
The PowerAssist function adds a new dimension to the PowerControl principle. Load peaks often only occur for a limited period of time. In such cases, the MultiPlus-Il immediately compensates for insufficient generator, shore power or mains power with energy from the battery. If the load is reduced, the "surplus" energy can be used to charge the batteries.
Solar power: alternating current even in the event of a grid failure
The MultiPlus-Il can be used with both non-grid-connected and grid-connected PV systems as well as other alternative energy systems. It can be used with both solar charge controllers and grid-connected inverters.
Two AC outputs
The main output ensures uninterrupted operation. In the event of a mains failure or an interruption in the shore/generator current, the MultiPlus-Il takes over the supply to the connected loads. Switching takes place so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed.
The second output only supplies power if alternating current is available at the input of the MultiPlus-Il. Loads that must not discharge the battery, such as a water heater, can be connected to this output. The loads connected to the second output are taken into account by the PowerControl and PowerAssist function.
Virtually unlimited power thanks to parallel and three-phase operation
Up to six multis can be connected in parallel if there is a high power requirement. In addition to the parallel connection, three units of the same model can also be configured for a three-phase output. But that's not all: up to 6 sets of three devices can be connected in parallel
On-site system configuration, monitoring and control
Settings can be changed in minutes using the VEConfigure software (requires a computer or laptop and an MK3 USB interface). Several monitoring and control options are available: Ekrano GX, Cerbo GX, Venus GX, laptop, computer, Bluetooth (with optional VE.Bus Smart Dongle), battery monitor, Digital Multi Control.
Remote configuration and monitoring
Install a Cerbo GX or other GX products to connect to the internet. The operating data can be stored and viewed free of charge on our VRM (Victron Remote Management) website. If systems are connected to the Internet, they can be accessed remotely and settings can be changed.

Certification in plain language: what other stores don't tell you
Now comes the most important part, where the wheat is separated from the chaff. An inverter that is connected to the public grid in Germany (i.e. for an ESS) must be certified in accordance with VDE-AR-N 4105. Without this certificate, no electrician may legally install the device, and in the event of damage you risk losing your insurance cover.
Status of the MultiPlus-II 48/6k5/100-50:
As this model is brand new, the official data sheet states "Certification pending".
What this means for you:
We at Verkauf-Bochum.de are in constant contact with Victron Energy. Before you buy this device for a grid-connected system, contact us! We will provide you with the current and binding certification status. We will not sell you a system that you are not allowed to operate legally. This honest advice is our promise.
- For stand-alone systems (off-grid): No VDE certification is required here. You can use the device without hesitation.
- For grid-connected systems (ESS): Use is only possible after certification has been granted.
An inverter is not a system: Why cheap batteries will ruin your project
The wildest recommendations are circulating on the Internet and on YouTube. Many people believe they can combine a high-end inverter like the MultiPlus-II with cheap no-name batteries or home-made battery banks.
From our years of experience, we can tell you that this is grossly negligent and extremely dangerous!
A stable and safe energy system is only as strong as its weakest link. The MultiPlus-II is designed to communicate with high-quality and tested battery systems (e.g. from Pylontech, BYD) via a CAN bus. This is the only way to ensure safe operation with correct charge and discharge management.
Remember: The MultiPlus-II is only the power center. For a complete system you also need:
- A brain: the Victron Cerbo GX for control and monitoring.
- A safe storage system: Compatible, certified lithium batteries.
- The right wires: Correctly dimensioned cables and fuses.
We help you to put together a system that not only works, but above all is safe.
Scalable up to the power plant: parallel and 3-phase operation
A single MultiPlus-II is just the beginning. The true strength of the Victron system lies in its modular expandability. For a fully-fledged home supply with three-phase current (e.g. for the stove or wallbox), you can connect three identical devices together to form a powerful 3-phase system.
A concrete example: Three MultiPlus-II 48/6k5/100-50 connected together provide you with a full 17.1 kW of continuous power - enough power for even the most demanding scenarios.
But here is an expert tip that you will hardly find in any data sheet and that will protect you from expensive planning errors:
⚠️ Important note: The largest models in the MultiPlus II series (8kVA, 10kVA and 15kVA) can no longer be connected in parallel to increase the power on a single phase. This technical restriction is crucial for system planning.
The MultiPlus-II 48/6k5/100-50 is therefore the most powerful model that you can still flexibly connect in parallel to achieve enormous single-phase outputs.
MultiPlus-II 48/6k5/100-50: Your next step towards energy independence
The Victron MultiPlus-II 48/6k5/100-50 is more than just a new product - it is the logical next step for anyone who takes their energy supply seriously. It offers the perfect balance of performance, intelligence and future-proofing.
