Victron MultiPlus-II Hybrid Inverter 48V 5000VA 70A-50A

Victron MultiPlus-II 48V/5000VA/70A-50A

The MultiPlus-II is a powerful DC-AC hybrid converter/charger with pure sine output, integrated adaptive battery charger and ultra-fast transfer switch power source - battery/source (external AC).

MultiPlus-II combines the functions of MultiPlus and MultiGrid

It has all the functions of the MultiPlus unit plus the possibility of connecting an external current sensor for PowerControl and PowerAssist functions with optimization of own consumption. It also has all the functions of a MultiGrid unit with built-in anti-islanding protection on its AC input - reinforced protection against unwanted supplies to the distribution network in the event of its failure.

ESS (Energy Storage System): Energy storage systems

The MultiPlus-II is a key element in the Victron ESS system, providing the flexibility to combine with solar MPPT controllers or grid PV inverters.

One AC input

MultiPlus-II is equipped with one AC input for connecting a distribution network or, for example, a generator. If two AC inputs are needed, then we choose the Quattro unit.

Two AC outputs

The MultiPlus-II is equipped with two AC outputs. The AC1 main output will ensure power supply without interruption. E.g. in UPS MultiPlus-II mode, it takes over the power supply of the connected consumers (in less than 20 ms) in the event of a failure of the distribution network or generator. The second AC output is only functional when an AC input (distribution network/generator) is available. A load that would quickly drain the batteries, such as a water heater, can therefore be connected to this output and it will only be powered from an AC source.

Four phases of charging with an adaptive charger with two outputs for charging the battery

The main DC output provides powerful full charge of the accumulators through the "adaptive charging" system. The software manages a three-stage automatic charging process to suit the battery condition and adds a fourth charging stage - trickle charge. MultiPlus-II is intended for charging all types of lead, alkaline and lithium batteries.

Virtually unlimited performance thanks to parallel operation

Up to 6 MultiPlus-II units can work in parallel to achieve higher performance. E.g. six 48/5000/70 units provide 25 kW (30 kVA) output power and 420 A charging power.

Three-phase operation

Three units of the same type can be configured for three-phase operation with phase shift. But that's not all, up to 6 parallel units can form one phase. A three-phase system can thus consist of up to 18 units with a total continuous output power of 75 kW (90 kVA) and a charging power of 1200 A.

Unique features of the PowerControl and PowerAssist functions

MultiPlus-II prevents overloading of a power-limited AC source, e.g. a current-limited electric connection or generator. If the input AC source should be overloaded due to large consumption, the charging current to the battery will be automatically reduced in the first step (PowerControl). Charging energy is diverted to power AC appliances. In the second step, the input AC source is strengthened by the current taken from the battery (PowerAssist). The AC output receives energy from the AC source and the battery (inverter) together.

Solar energy

You can have AC power available even in the event of a power outage. MuliPlus-II can be used both in off-grid (island) systems and in photovoltaic systems permanently connected to the distribution network. MultiPlus-II is not equipped with an input for a PV array, but it is intended to work with MPPT controllers (DC coupling systems) or mains converters (AC coupling systems) located at the AC input and/or AC output.

System configuration

• In the case of a simple, for example, UPS installation, the setting can be easily done in a few minutes using the DIP switches on the MultiPlus-II or the VE.Configure 3 software and a PC.
• Parallel and three-phase applications can be configured using the VE.Bus Quick Configure software (up to three units) or more complex systems using the VE.Bus System Configurator software (over 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 the VE.Configure 3 software using the appropriate assistants (specialized functions for specific applications).
• MultiPlus-II has several programmable relays and auxiliary contacts for a whole range of additional functions.
• You can download the basic VE.Configure 3 software, as well as other software for configuration, for free at this address [www.victronenergy.com/support-and-downloads/software](https://www.victronenergy.com/ support-and-downloads/software).
• For the mentioned software you will need a PC communication interface MK3-USB.
