Victron MultiPlus-II 48V/8000VA/110A-100AWARNING: MultiPlus II 8,10, and 15kVA units cannot be operated in parallel.
The MultiPlus-II is a powerful DC-AC hybrid inverter/charger with a pure sine wave output, integrated adaptive battery charger, and ultra-fast transfer switch for power sources - battery/mains (external AC).
The MultiPlus-II combines the features of MultiPlus and MultiGrid
It has all the features of the MultiPlus unit and additionally allows for the connection of an external current sensor for PowerControl and PowerAssist functions with self-consumption optimization.
It also includes all the features of the MultiGrid unit with built-in anti-islanding protection on its AC input – enhanced protection against unwanted supply to the grid in the event of a grid failure.
ESS (Energy Storage System): Energy storage systems
The MultiPlus-II is a key component of the Victron ESS system, providing flexibility for integration with solar MPPT controllers or grid-tied PV inverters.
One AC input
The MultiPlus-II is equipped with one AC input for connection to the grid or, for example, a generator. If two AC inputs are required, the Quattro unit should be chosen.
Two AC outputs
The MultiPlus-II has two AC outputs. The main output AC1 ensures uninterrupted power supply. For example, in UPS mode, the MultiPlus-II takes over the power supply to the connected appliances (within 20 ms) in the event of a grid or generator failure.
The second AC output is functional only when an AC input (grid/generator) is available. Loads that would quickly deplete the batteries, such as a water heater, can be connected to this output and powered only by the AC source.
Four-stage charging with adaptive battery charger and two outputs
The main DC output provides powerful full-rate battery charging through the "adaptive charging" system. The software controls a three-stage automatic charging process to suit the battery's state, and adds a fourth charging stage - maintenance charging. The MultiPlus-II is designed to charge all types of lead-acid, alkaline, and lithium batteries.
Three-phase operation
Three units of the same type can be configured for three-phase operation with phase shift.
Unique features of PowerControl and PowerAssist functions
The MultiPlus-II prevents overloading of a power-limited AC source, such as a current-limited electrical connection or generator. If there is a high demand that would overload the input AC source, the charging current to the battery will be automatically reduced in the first step (PowerControl). The energy for charging is redirected to power AC appliances. In the second step, the input AC source is reinforced by current drawn from the battery (PowerAssist). The AC output receives a combination of energy from the AC source and the battery (inverters).
Solar energy
You can have AC power available even during a grid outage. The MultiPlus-II can be used in both off-grid (stand-alone) systems and photovoltaic systems permanently connected to the grid. The MultiPlus-II does not have a PV input, but it is designed to work with MPPT controllers (DC coupling systems) or grid inverters (AC coupling systems) located at the AC input and/or AC output. More information can be found here in the ESS description.
System configuration
For simple installations like UPS, the settings can be easily done within a few minutes using the DIP switches on the MultiPlus-II or with VE.Configure 3 software and a PC.
Three-phase applications can be configured using VE.Bus Quick Configure software (up to three units) or more complex systems using VE.Bus System Configurator software (more than three units) and a PC.
Off-grid and hybrid PV installations, to support self-consumption and greater energy independence, which include grid inverters and/or solar MPPT chargers, can be configured using VE.Configure 3 software with specific wizards (specialized functions for specific applications).
The MultiPlus-II has several programmable relays and auxiliary contacts for a wide range of additional functions.
The basic VE.Configure 3 software, as well as other configuration software, can be downloaded for free at this address www.victronenergy.com/support-and-downloads/software.
You will need the MK3-USB communication interface for the mentioned software.
Remote monitoring and system configuration
Monitor and control your system locally or remotely over the internet from anywhere in the world using the free VRM app and the free VRM portal: https://vrm.victronenergy.com/landingpage
Access can be done from a phone, tablet, laptop, or computer (various operating systems). For remote access, you need one of the following control panels, and then you have the ability to monitor and configure the system from anywhere in the world: Color Control GX, Venus GX, Cerbo GX
In combination with Cerbo GX, ColorControl GX, or Venus GX, it provides battery state of charge (SOC) monitoring in percentage.
MultiPlus-II offers many operating modes and can provide solutions for various user requirements.
