Description

Victron MultiPlus II 5000/48/70-50 Inverter/Charger is an Inverter/Charger with device networking built-in, the MultiPlus-II GX communicates with a solar charger, batteries, and other devices to control a grid-connected, off-grid, or remote power installation. Capable of parallel operation for increased power output or battery charge rates, the MultiPlus-II GX can also be configured for a three-phase supply. A host of advanced features – such as uninterrupted power supply, setting load limits, and supplementing limited grid-power availability with battery power – can all be controlled straight from your phone or smart device. Remote monitoring is also possible.

The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid. It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimise self-consumption with external current sensing (max. 32A).

PowerAssist: The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload occurs. The second level will boost the output of a generator or shoreside supply with power from the battery.

The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters.

UPS function: In the event of a grid failure or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will operate without disruption.

Monitor and control your system locally (LAN) or remotely via the internet from anywhere in the world using the free VRM app. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control via the required Color Control GX or Venus GX, from adjusting your Multi to auto-starting a back generator and more… This Multiplus comes integrated with GX.

A MultiPlus, plus ESS (Energy Storage System) functionality 

The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external  current sensor option which extends the PowerControl and PowerAssist function to 50 A resp. 100 A. 

The MultiPlus-II is ideally suited for professional marine, yachting, vehicle and land based off -grid applications.

It also has built-in anti-islanding functionality, and an increasingly long list of country approvals for ESS application.  Several system configurations are possible. For more detailed information see the ESS Design and configuration manual. PowerControl and PowerAssist – Boosting the capacity of the grid or a generator 

A maximum grid or generator current can be set. The MultiPlus -II will then take account of other AC loads and use  whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl  function). 

PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a  limited period, the MultiPlus-II will compensate insufficient generator, shore or grid power with power from the battery.  When the load reduces, the spare power is used to recharge the battery. 

Solar energy: AC power available even during a grid failure 

The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is  compatible with both solar charge controllers and grid -tie inverters. 

Two AC Outputs 

The main output has no break functionality. The MultiPlus -II takes over the supply to the connected loads in the event of  a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that  computers and othe r electronic equipment will continue to operate without disruption. 

The second output is live only when AC is available on the input of the MultiPlus -II. Loads that should not discharge the  battery, like a water heater for example, can be connected to this output. 

Virtually unlimited power thanks to parallel and three phase operation 

Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/5000/70 units, for example, will provide  25 kW / 30 kVA output power with 420 Amps charging capacity. 

In addition to parallel connection, three units of the same model can be configured for three phase output. But that’s not  all: up to 6 sets of three units can be parallel connected for a 75 kW / 90 kVA inverter and more than 1200 Amps charging  capacity. 

The MultiPlus-II 8k, 10k, and 15k models can only be connected in parallel if an external AC transfer switch is used. For  more information see the MultiPlus-II External Transfer Switch application manual . 

On-site system configuring, monitoring and control 

Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3 -USB interface  needed). 

Several monitoring and control options are available: Cerbo GX, Ekrano GX, laptop, computer, Bluetooth (with the  optional VE.Bus Smart dongle), Battery Monitor, Digital Multi Control Panel. 

Remote configuring and monitoring 

Install a Cerbo GX or other GX product to connect to the internet. 

Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge. When connected to the internet, systems can be accessed remotely, and settings can be changed. 

Standard marine, mobile or off -grid application 

Loads that should shut down when AC input power is not available can  be connected to a second output (not shown). These loads will be taken  into account by the PowerControl and PowerAss ist function in order to  limit AC input current to a safe value when AC power is available. 

Grid parallel topology with MPPT solar charge controller The MultiPlus-II will use data from the external AC current sensor (must be ordered separately) or power meter to optimis e self consumption a nd, if required, to prevent grid feed. In case of a power outage, the MultiPlus-II will continue to supply the critical loads 

Ekrano GX or Cerbo GX  

Provides intuitive system control and monitoring and  enables access to our free remote monitoring website:  the VRM Online Portal. 

VRM Portal 

Our free remote monitoring website (VRM) will  display all system data in a comprehensive graphical  format. System settings can be changed remotely via  the portal. Alarms can be received by e -mail or push  notification. 

VRM app helps you monitor and manage  your Victron Energy  system from your smart  phone and tablet.  Available for both iOS  and Android.
