MultiPlus , as the name suggests, is a combination of an inverter and charger in one elegant package. Its range of features includes a pure sine wave inverter, adaptive charging, PowerAssist technology and other features for integration into various types of systems.
One AC input
The MultiPlus is equipped with one AC input for connection to the distribution network or, for example, a generator.
If two AC inputs are required, then select the Quattro unit.
Two AC outputs
MultiPlus is equipped with two AC outputs. The main AC1 output ensures an uninterrupted power supply. For example, in UPS mode, the MultiPlus will take over power to connected appliances (in less than 20 milliseconds) in the event of a mains or generator failure.
The second output is only functional when the AC input (distribution network/generator) is available. Therefore, a load that would quickly drain the batteries, such as a water heater, can be connected to this output and will only be powered from the AC source (second output available on models rated 3kVA and above).
Four stages of charging with an adaptive charger and two outputs for battery charging
The main output provides powerful battery charging through an "adaptive charging" system. The software controls the three-stage automatic charging process to suit the condition of the battery and adds a fourth charging stage - maintenance charging. In addition to this, MultiPlus can charge a second battery using an independent charging output designed for, for example, generator starter batteries. Multiplus is designed to charge all types of lead acid, alkaline and lithium batteries.
Virtually unlimited power thanks to parallel operation
Up to 6 MultiPlus units can operate in parallel to achieve higher performance.
Three-phase operation
Three units of the same type can be configured for three-phase operation. But that's not all: up to 6 sets of three units can be connected in parallel.
Unique features of PowerAssist
MultiPlus prevents overloading of a power-limited AC source, e.g. a current-limited power connection. Should the AC input power source be overloaded, the charging current to the battery will be automatically reduced in the first place. Secondly, the output AC current is then boosted by the current drawn from the battery.
Solar energy
AC power can be available even in the event of a grid failure.
MuliPlus can be used in both off-grid (islanded) systems and grid-connected PV systems. The MultiPlus is not equipped with an input for the PV array, but is designed to work with MPPT controllers (DC coupling systems) or grid-tied inverters (AC coupling systems).
System configuration
- In the case of a stand-alone e.g. UPS installation, the setup can be easily done in a few minutes using the DIP switches.
- Parallel and three-phase applications can be configured using the VE.Bus Quick Configure software and the VE.Bus System Configurator software.
- Off-grid and hybrid PV installations for self-consumption that include grid-tied inverters or MPPT solar chargers can be configured using the Assistant (dedicated software for specifict applications).
- The configuration software can be downloaded for free from the following link (VE.Configure 3): https://www.victronenergy.com/support-and-downloads/softwareFor this software you will need a PC communication interface MK3-USB
Remote monitoring and system configuration
Monitor and control your system locally (LAN) or remotely over the Internet from anywhere in the world using the free VRM application and the free VRM portal.

Access can be from tele:phone, tablet, laptop or PC for different operating systems. There is no end to the level of control, using one of the following control panels you can monitor and configure the system from anywhere in the world.
MultiPlus offers many variants of operation and we are able to offer solutions to a range of user requirements. Here are the most common operating modes to give you an idea:
ESS mode - Energy Storage System
This mode is only for photovoltaic installations with an available distribution network (DS), a requirement to maximise the use of the solar energy produced in combination with a conventional DS and the possibility of storing excess energy in batteries.
A detailed manual for the ESS system can be found at the following link: https://www.victronenergy.com/live/ess:design-installation-manual
Examples of ESS system configurations:
1. Conventional grid power plant with energy storage
As soon as the meter detects a supply to the distribution network (hereafter DS), the ESS system starts storing the excess energy in a battery. Once the net meter detects a purchase of energy from the DS, the ESS system supplies energy from the battery to the load. In the event of a DS failure, the PV does not go and the critical appliances (in the "Critical Loads" scheme) are fed from the AC output of the MultiPlus/Quattro unit - this ensures that only priority appliances discharge our battery and non-priority appliances are disconnected.
2. The energy from the PV panels is handled by the MPPT solar controller.
This solution is particularly suitable for smaller installations and has the advantage of higher efficiency - the DC energy from the PV is stored directly in the DC battery. Compared to the previous example, it achieves higher efficiency because there is no need to process the DC current to AC using a grid inverter and then convert it again from AC to DC for storage in the battery - this causes losses of 20-30%. In the event of a blackout, only critical appliances are re-energized, but the PV system remains fully operational and operates in a completely islanded/autonomous mode.
3. Option without network meter. Again, possible in combination with both the mains inverter and the MPPT solar controller.
4. This is also how an ESS system can work and allows the combination of all three PV sources at the same time.
MultiPlus/Quattro is connected to the battery and supplies power to appliances via AC1 output. A generator can be connected to the AC input, which can also be started automatically on demand from the inverter or manually. Once the generator starts, the unit supplies power to AC outputs 1 and 2 and simultaneously charges the batteries along with the solar panels. Once the generator shuts down, then power is again supplied from the battery/solar panels. The unit has two load outputs - the first output is functional all the time, the second output only when the generator is running.
Mobile app mode - motorhomes, military vehicles, ambulances
The MultiPlus unit takes care of the complete on-board power supply solution. As soon as we connect to the power supply, for example in the garage, the MultiPlus unit draws energy to power the appliances and charges the battery at the same time. As soon as we disconnect from the connection, energy is supplied from the battery.
UPS mode
Very popular basic UPS mode. As soon as the distribution network fails, MultiPlus immediately starts powering the backed-up appliances from the battery. Once the mains supply is restored, it switches back to DS power and automatically performs a full battery charge to ensure the system is ready for the next possible outage. All this happens quickly without interrupting the power supply to the appliances.
