MultiPlus-II

A MultiPlus, plus ESS (Energy Storage System) function

The MultiPlus-II 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-II is ideally suited for professional shipping, yachts, vehicles and land-based, off-grid applications. The device also has a built-in anti-islanding function and is being approved for ESS applications in more and more countries. Several different system configurations are possible. Further information can be found in the ESS Design & Configuration manual.

PowerControl and PowerAssist - increasing grid or generator output

A maximum grid or generator current can be set. The MultiPlus-II then takes account of other connected AC consumers and only uses the current that is still "left over" to charge the battery. This prevents the generator or the 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-II immediately compensates for insufficient generator, shore power or mains power with energy from the battery. If the load is reduced, i.e. consumers are switched off, the available energy can then be used to recharge the batteries.

Solar power: alternating current even in the event of a power failure

The MultiPlus-II can be used with both off-grid 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-II takes over the supply to the connected loads. The switchover happens 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-II. Consumers that must not discharge the battery, such as a water heater, can be connected to this output.

Virtually unlimited power thanks to parallel and three-phase operation

Up to six Multis can be connected in parallel for high power requirements. With six 48/5000/70
units, for example, this results in 25 kW/30 kVA output power with 420 A charging capacity.
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: by connecting up to 6 sets of three units in parallel, you get 75 kW/90 kVA inverter power or 1200 A charging current.

System configuration, monitoring and control on site

The settings can be changed in a matter of minutes using the VEConfigure software (a computer or laptop and an MK3 USB interface are required).
Several monitoring and control options are available: Colour Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart Dongle), battery monitor, Digital Multi control panel.

Remote configuration and monitoring

Install a Color Control 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.
