Two AC inputs and two AC outputs

The Quattro-II can be connected to two independent AC sources, for example a shore supply and a generator, or two generators.
The Quattro-II automatically connects to the active source. The main output has an uninterruptible power supply function. In the event of a grid failure, or when the shore supply or a generator is disconnected, the Quattro-II takes over the supply to the connected loads. This transfer is so fast (less than 20 milliseconds) that the operation of computers or other electronic equipment is not disrupted.
The second output is only live when AC power is available on one of the Quattro-II inputs. Loads that should not discharge the battery, such as an air-conditioning unit or a water heater for example, can be connected to this output.

Victron Energy Quattro-II: a Quattro with ESS (Energy Storage System) functionality

The Quattro-II is a multifunctional inverter/charger with all the features of the Quattro, plus an optional external current transformer that extends the PowerControl and PowerAssist functions to 50 A and 100 A respectively.
The Quattro-II is ideal for professional marine installations, sailing yachts, vehicles and off-grid systems.
It also features built-in anti-islanding and an ever-growing list of country certifications for the ESS application. Several system configurations are possible.

Automatic and uninterrupted switchover

In the event of a power failure, or when the generator is switched off, the Quattro-II switches to inverter mode and takes over the supply to the connected appliances. This transfer is so fast that the operation of computers and other electronic equipment is not disrupted (uninterruptible power supply, or UPS, function). This makes the Quattro-II a back-up power system perfectly suited to industrial and telecommunications applications. The maximum switched power is 50 A.

Auxiliary AC output

In addition to the usual uninterrupted output, an auxiliary output is available which disconnects its load when running on battery. For example: an electric boiler that may only operate when the genset is running or when shore power is available.

Virtually unlimited power thanks to parallel operation

Up to 6 Quattro-II units can operate in parallel to obtain more output power. For example, six 48/5000/70 units will deliver 25 kW / 30 kVA of output power and 420 A of charging capacity.
In addition to parallel connection, three units of the same model can be configured for a three-phase output. But that is not all: up to 6 sets of three units can be connected in parallel for an inverter of 75 kW / 90 kVA and more than 1200 A of charging capacity.

PowerControl – making the most of a limited shore supply

The Quattro-II can deliver enormous charging power, which places a heavy demand on shore power or the generator. A maximum power level can therefore be set. The Quattro-II then takes the other power users into account and uses only the « surplus » current to charge the batteries.

PowerAssist – extended use of your generator and shore supply: the Quattro-II co-supply function

This function adds a further dimension to the PowerControl principle by allowing the Quattro-II to supplement the capacity of the alternative source. Because peak power is usually required only for a short time, the Quattro-II ensures that any shortfall of shore or generator power is immediately compensated by the batteries. When demand drops, the surplus power is used to recharge the batteries. This unique function offers a definitive solution to shore-power limitations: high-power electrical appliances, dishwashers, washing machines, electric cookers, etc. can all run from a 16 A shore connection, or less. A smaller generator can also be installed.

Stand-alone operation during a grid failure

Homes or buildings fitted with solar panels, or with a micro power plant for electricity and heating, or other sustainable energy sources, thus have an independent electricity supply that can be used to power essential equipment (central-heating pumps, refrigerators, freezers, internet connections, etc.) during a power cut. There is one problem, however: these grid-connected renewable sources are cut off as soon as the grid fails. With a Quattro-II and batteries, this problem is easily solved: the Quattro-II can replace the grid during an outage. When the renewable sources produce more power than is needed, the Quattro-II uses the surplus to charge the batteries; and during a power cut, the Quattro-II supplies extra power from the batteries.

Programmable relay

The Quattro-II is fitted with a programmable relay, configured by default as an alarm relay. This relay can be programmed for all kinds of applications, for example as a start relay for a generator.

Solar energy

The Quattro-II is perfectly suited to solar energy applications. It can be used in stand-alone systems as well as in grid-connected systems.

Remote monitoring and control

When combined with a GX device (for example a Cerbo GX), you can monitor and control your Quattro and your system or systems either locally (LAN) or remotely over the internet from anywhere in the world, through the free VRM app and the free VRM web portal. You can access it from a phone, tablet, laptop or PC running various operating systems. The level of control over your system is unlimited, whether to adjust settings on your Multi or to start your back-up generator automatically, and much more.
