MultiPlus-II 48/3000 - 35-50 - 120V - UL 458 UL 1741

The MultiPlus-II, an inverter/charger, 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 optimize self-consumption with external current sensing (max. 32A). It also has all the features of the MultiGrid with built-in anti-islanding and increasingly long list of country approvals.

PowerAssist

The MultiPlus-II will prevent the 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 would occur. The second level will boost the output of a generator or shoreside supply with power taken from the battery.

ESS: Energy Storage Systems

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.

Uninterrupted AC power (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.

Remote Monitoring and Control

When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backup generator and more.

MultiPlus 12/3000 - 120-50 - 230V - VE.Bus

The MultiPlus, as the name suggests, is a combined inverter and charger in one elegant package. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, and multiple system integration features.

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 (a second output is available on models rated at 3 kVA and more).

Virtually Unlimited Power Thanks to Parallel Operation

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

Three Phase Capability

In addition to parallel connections, 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 connected in parallel for a 75 kW / 90 kVA inverter and more than 2000 Amp 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 shoreside 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.

PowerAssist - Boosting the capacity of shore or generator power

This feature takes the principle of PowerControl to a further dimension. It allows MultiPlus to supplement the capacity of the alternative source. Where peak power is 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.

Solar energy: AC Power is Available Even During a Grid Failure

The 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 the 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 for GX or other GX devices, smartphone, 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.
