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.
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.
120/240 V input and output, or 120 V input and output (always 120 V output when in inverter mode)
The two AC inputs can be supplied from a split-phase 120/240 V source or a single-phase 120 V source.
When one of the AC sources is available, the Quattro will feed through the AC to its output. The output will therefore mirror the AC input.
The inverter/charger connects to the neutral and the preferred input line (L1). The power needed to charge the batteries will therefore be drawn from L1.
The Quattro switches to inverter operation when no AC source is available. The inverter output is 120 V single-phase. In invert mode, the Quattro connects both output lines (L1 and L2) together to provide 120 VAC to loads on either line.
Any 240 V loads will therefore be supplied only when the Quattro is supplied by a split-phase AC source. This prevents heavy loads such as water heaters or 240 V air conditioners from discharging the battery.
PowerControl and PowerAssist - Boosting the capacity of the grid or a generator
A maximum grid or generator current can be set. The Quattro 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 will compensate for insufficient generator, shore or grid power with power from the battery.
When the load reduces, the spare power is used to recharge the battery (available on L1 input only).
Two AC inputs and two AC outputs
The Quattro can be connected to two independent AC sources, for example,shore-side power and a generator, or two generators. The Quattro-II will automatically connect to the active source.
The main output has a no-break functionality. The Quattro takes over the supply to the connected 120 V loads in the event of a grid failure or when shore/generator power is disconnected. The transfer time of the L1 output is less than 18 milliseconds so that computers and other electronic equipment will continue to operate without disruption.
The transfer time of the L2 output is longer: approximately 40 milliseconds.
The second (auxiliary) output is live only when AC is available on the input of the Quattro. Loads that should not discharge the battery can be connected to this output.
Virtually unlimited power thanks to parallel and three-phase operation
Up to 6 Quattros can operate in parallel to achieve higher power output.
In addition to parallel connection, three units of the same model can be configured for three-phase output.
In multi-phase setups, L2 is disabled on all units.
On-site system configuring, monitoring and control
Settings can be changed in a matter of minutes with the VictronConnect app or VEConfigure software (computer or laptop and MK3-USB interface needed).
Several monitoring and control options are available: Cerbo GX, Color Control GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, and 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.
