MultiPlus 48/3000/35-50 VE.Bus

3000VA pure sine inverter 48V + internal 35A IUoU battery charger + 50A AC transfer switch

designed for Caravan, Boat, Motor home and Offgrid systems

MultiPlus Compact-functional
The MultiPlus Compact gets its name from the multiple functions it can perform. It is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact enclosure. Beside these primary functions, however, the MultiPlus Compact has several advanced features that provide a range of new applications as outlined below


Two AC Outputs
The main output has no break functionality. The MultiPlus 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 other electronic equipment will continue to operate without disruption.
The second output is live only when AC is available on the input of the MultiPlus. Loads that should not discharge the battery, like a water heater for example can be connected to this output (second output available on models rated at 3 kVA and more).

Dealing with limited generator, shore side or grid powerThe MultiPlus is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side supply (nearly 10 A per 5 kVA Multi at 230 VAC). With the Multi Control Panel a maximum generator or shore current can be set. The MultiPlus will then take account of other AC loads and use whatever is extra for charging, thus preventing the generator or shore supply from being overloaded.

Boosting the capacity of shore or generator powerThis feature takes the principle of PowerControl to a further dimension. It allows the MultiPlus to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, the MultiPlus will make sure that insufficient shore or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery.

Remote control: Digital Multi Controll (optionally available)
The Digital Multi Control is used to remotely view and adjust AC input currents, and turn on and off the Multi or Quattro. It is designed to integrate cleanly with your boat, vehicle or house system control panel.


Adaptive 4-stage charging characteristics: bulk – absorption – float – storage
The microprocessor-driven adaptive battery management system can be adjusted for various types of batteries. The adaptive function automatically adapts the charging process to battery use.

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

Programmable relay
The MultiPlus is equipped with a programmable relay that by default is set as an alarm relay. The relay can be programmed for all kinds of other applications however, for example as a starter relay for a generator.

Virtually unlimited power thanks to parallel operation
Up to 6 Multis can operate in parallel to achieve higher power output. Six 24/5000/120 units, for example, will provide 25 kW / 30 kVA output power with 720 Amps charging capacity.

Threephase capability
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 2000 Amps charging capacity.

Solar energy:
AC power available even during a grid failureThe MultiPlus can be used in off grid as well as grid connected PV and other alternative energy systems.Loss of mains detection software is available.

System configuring
-In case of a stand-alone application, if settings have to be changed, this can be done in a matter of minutes with a DIP switch setting procedure.
-Parallel and three phase applications can be configured with VE.Bus Quick Configure and VE.Bus System Configurator software.
-Off grid, grid interactive and self-consumption applications, involving grid-tie inverters and/or MPPT Solar Chargers can be configured with Assistants (dedicated software for specific applications).

On-site Monitoring and control
Several options are available: Battery Monitor, Multi Control Panel, Color Control GX or other GX devices, smartphone or tablet (Bluetooth Smart), laptop or computer (USB or RS232).

Remote Monitoring and control
Color Control GX or other GX devices.Data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.

Remote configuring
When connected to the Ethernet, systems with a Color Control GX or other GX device can be accessed and settings can be changed remotely.

The interface cable for configuration via PC or laptop can be found here: MK3-USB

The remote controls, in two optically different versions, can be found here: Digital MultiControl oder  Digital MultiControl GX
