Similar to the MultiPlus, the Quattro is also a combined inverter and charger. Additionally it can accept two AC inputs and automatically connect to the active source. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology plus multiple system integration features such as three or split phase operation and parallel operation.Two AC inputs with integrated transfer switch
The Quattro can be connected to two independent AC sources, for example the public grid and a generator, or two
generators. The Quattro will automatically connect to the active source.
Two AC Outputs
The main output has no-break functionality. The Quattro 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 Quattro. Loads that should not discharge the
battery, like a water heater for example, can be connected to this output.
Split phase and three phase capability
Two units can be configured for split phase, and three units can be configured for three phase output. But that’s not all: up to
4 sets of three units can be parallel connected to provide 96W / 120kVA inverter power and more than 1600A charging
capacity

A MultiPlus-II with LCD and GX functionality
The MultiPlus-II GX integrates a MultiPlus-II inverter/charger and a GX device with a 2 x 16 character display.
Display and Wi-Fi
The display reads battery, inverter and solar charge controller parameters.
The same parameters can be accessed with a smartphone or other Wi-Fi enabled device.
GX device
The integrated GX device includes:
• A BMS-Can interface. This can be used to connect to a compatible CAN-bus managed battery. Note that this not a
VE.Can compatible port.
• A USB port.
• A Ethernet port.
• A VE.Direct port.
Applications
The MultiPlus-II GX is intended for applications where additional interfacing with other products and/or remote
monitoring is required, such as on-grid or off-grid energy storage systems and certain mobile applications.
Parallel and three phase operation
Only one GX unit is needed in case of Parallel and three phase operation.

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

Note: for a short period of time this product was called MultiGrid-II.

Models:
3000VA – 5000VA – 8000VA – 10000VA – 15000VA

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, plus multiple system integration features.

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 (second output 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 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 75 kW / 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 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 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.

Solar energy: AC power 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 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).
