Victron Multiplus Pure Sine Wave Marine Inverter Charger

Victron Multiplus

The MultiPlus 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. Next to these primary functions, the MultiPlus has several advanced features, 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 one of the inputs 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 3kVA and more).

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.

Three phase 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 huge 75kW / 90 kVA inverter and more than 2000 Amps charging capacity.

PowerControl – Dealing with limited generator, shore side or grid power
The MultiPlus is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side supply (nearly 10A per 5kVA Multi at 230VAC).

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.

PowerAssist – Boosting the capacity of shore or generator power
This feature takes the principle of Power Control 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.

Four stage adaptive charger and dual bank battery charging
The main output provides a powerful charge to the battery system by means of advanced ‘adaptive charge’ software. The software fine-tunes the three stage automatic process to suit the condition of the battery, and adds a fourth stage for long periods of float charging.

The adaptive charge process is described in more detail on the Phoenix Charger datasheet and on our website, under Technical Information.
In addition to this, the MultiPlus will charge a second battery using an independent trickle charge output intended for a main engine or generator starter battery (trickle charge output available on 12V and 24V models only).

Victron Multiplus System configuring has never been easier

• 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, Ve.Net Blue Power Panel, Colour Control Panel, smartphone or tablet (Bluetooth Smart), laptop or computer (USB or RS232).

Remote Monitoring and control
Victron Ethernet Remote, Victron Global Remote and the Colour Control Panel. 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 Colour Control panel can be accessed remotely and settings can be change.
