Victron Energy Quattro 12/5000/220-100/100 230V VE.Bus Inverter Charger – QUA125020000

Product Description

The Victron Energy Quattro 12/5000/220-100/100 230V VE.Bus is a powerful inverter/charger designed for demanding 12V battery-based electrical systems. Combining a pure sine wave inverter, a high-output 220A battery charger and an integrated automatic transfer switch, the Quattro provides a versatile solution for marine, mobile, backup-power and off-grid installations.

With a 5,000VA inverter rating and up to 4,000W continuous active output at 25°C, this unit can supply a wide range of compatible 230V AC equipment. Its high-capacity charger supports rapid charging of suitable battery banks when connected to an appropriate AC supply.

Dual AC Inputs for Flexible Power Management

A key advantage of the Quattro is its ability to connect to two independent AC power sources, such as shore power and a generator. The unit automatically selects the available source according to its configuration, reducing the need for a separate external changeover switch in appropriately designed systems.

The integrated transfer switching and inverter functions help maintain AC power when an external source becomes unavailable.

PowerControl and PowerAssist

PowerControl allows the maximum AC input current to be configured to suit the available supply. The Quattro can reduce its battery charging demand to help prevent overloading a limited mains or generator connection.

PowerAssist supplements a limited external AC supply with power from the battery through the inverter when connected loads temporarily demand more power than the source can provide.

These features are particularly useful in installations where generator capacity or shore-power availability is limited.

Two AC Outputs

The main AC output supplies connected loads during normal external-power operation and inverter operation. The second output is intended for loads that should only operate when external AC power is available. This can help separate essential equipment from non-essential loads and preserve battery capacity when operating from the inverter.

Typical Applications

The Victron Energy Quattro 12/5000/220-100/100 is suitable for correctly engineered systems requiring substantial inverter output and flexible AC source management, including:

• Large boats and marine electrical systems

• Motorhomes and specialist vehicles with high electrical demand

• Off-grid properties and remote buildings

• Battery-based backup power installations

• Systems using both shore power and generator input

• Renewable energy installations with compatible battery storage

• Commercial and industrial mobile power systems

• Installations requiring automatic switching between two AC sources

Installation and Compatibility

The Quattro is designed for use with a suitable 12V battery bank and appropriately rated AC and DC infrastructure. Its high inverter output and 220A charging capability mean that battery discharge capability, charging limits, cable sizing and protective devices must be carefully assessed.

At high loads, a 12V inverter system can draw several hundred amps from the battery. The battery bank, DC cabling, fusing, isolators and connections must therefore be rated for the expected current and installation conditions.

Both AC inputs must be wired and configured correctly for the intended sources. AC distribution, earthing, residual-current protection and generator compatibility should be considered as part of the complete system design.

VE.Bus communications support integration with compatible Victron monitoring and control equipment. Parallel or three-phase configurations require compatible units and correct commissioning.

Installation and commissioning should be carried out by a suitably qualified professional in accordance with Victron Energy's instructions and applicable electrical regulations.

Important product identification: QUA125020000 is the 12V Quattro rated at 5,000VA, with a 220A battery charger and two 100A AC inputs. Do not confuse it with the 24V or 48V Quattro models, which have different battery-voltage requirements and specifications.
