Victron Quattro-II 2x120V Inverter Charger Description

Similar to the MultiPlus-II 2x120V, the Quattro-II 2x120V is a combined inverter and charger specifically designed for standard North American 50A 120/240VAC split-phase applications. Additionally, it can accept two AC inputs and automatically connects to the active source.

Whether it is supplied from shore power or a generator, the Quattro-II 2x120V can accept and pass through both lines of a 120/240V supply, with the capability to utilise the full 50A for charging and AC loads. When connecting to a single-phase 120V supply, the L1 input of the Quattro-II 2x120V will accept incoming power for charging and passthrough while combining the L1 and L2 outputs for single-phase 120V on each line.

The Quattro switches to inverter operation when no AC sources are available. The inverter output is also 120V single-phase. In inverter mode, the Quattro-II 2x120V internally connects both lines L1 and L2 together to provide 120VAC to loads on either output. Therefore, in all connection circumstances, both sides of a distribution panel will be supplied with 120V. However, 240VAC is only available when the Quattro is supplied by a split phase 120/240VAC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.

The Quattro-II 2x 120V has all of the expected features of our versatile inverter/charger range, including PowerControl, PowerAssist, Input Current Limit, two AC outputs, as well as parallel and 3-phase configuration for larger capacity VE.Bus systems. Suitable for LiFePO4 batteries and a variety of other battery technologies.

A Quattro, plus ESS (Energy Storage System) functionality
The Quattro-II can be connected to two independent AC sources, for example the public grid and a generator, or two generators. The Quattro-II will automatically connect to the active source.


PowerControl and PowerAssist - Boosting the capacity of the grid or a generator
A maximum grid or generator current can be set. The Quattro-II will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).
PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a limited period, the Quattro-II will compensate insufficient generator, shore or grid power with 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 Quattro-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is compatible
with both solar charger controllers and grid-tie inverters.
Two AC Outputs
The main output has no break functionality. The Quattro-II 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. Loads that should not discharge the battery, like a water heater for example, can be connected to this output.


On-site system configuring, monitoring and control
Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface
needed).
Several monitoring and control options are available: Cerbo GX, Color 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 configuring and monitoring
Install a Cerbo GX or other GX product to connect to the internet.
Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
When connected to the internet, systems can be accessed remotely, and settings can be changed.
