Victron Energy Quattro 48/5000/70 120V VE.Bus UL-Listed Inverter and Charger

Quattro 48/5000/70 100/100 120V VE.Bus UL-Listed

Multifunctional

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 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 will automatically connect to the active source. The main output has no-break functionality. In the event of a grid failure, or shore or generator power being disconnected, the Quattro takes over the supply to the connected loads. 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, such as air-conditioning or a water heater can be connected to this output.

Unique PowerAssist Feature

The Quattro will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.

Virutually Unlimited Power Thanks to Parallel Operation

Up to 6 Quattros can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible. Please check our datasheets to see which models have paralleling, three phase and split phase capabilities.

Remote Monitoring Control

When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Quattro and system or systems locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Quattro to auto starting a backupgenerator and more.

The Victron Energy Quattro 48/5000/70 120V VE.Bus UL-Listed is a versatile and high-performance inverter and charger designed for demanding power systems. This model combines true sine wave inverter technology with advanced adaptive charging capabilities, ensuring reliable power delivery and efficient battery management. Its innovative hybrid PowerAssist technology helps prevent overloads by intelligently boosting power from the battery, making it ideal for applications with limited AC sources or fluctuating loads.
Designed with dual AC inputs, the Quattro can automatically connect to two independent power sources, such as shore power and a generator, or two generators. The system seamlessly switches to the active source, providing no-break power to connected loads with switching times of less than 20 milliseconds. The main output is capable of supplying continuous power, while a secondary output, only live when AC is available, is suitable for loads that should not discharge the batteries, such as water heaters or air conditioning units. This setup enhances system stability and ensures critical loads remain powered during grid or source interruptions.
The Quattro supports parallel operation of up to six units, enabling higher power outputs and the possibility of three-phase or split-phase configurations. This scalability makes it suitable for larger installations and complex power systems. Additionally, when paired with a GX device like the Cerbo GX, users can remotely monitor and control the system via the VRM platform, accessible from any device with an internet connection. This level of control allows for system adjustments, auto-starting backup generators, and comprehensive system management from anywhere in the world.
Constructed for durability and compliance, the Victron Quattro is UL-listed and built to meet rigorous safety standards. Its compact design, combined with advanced features, makes it an excellent choice for both residential and commercial power backup solutions, off-grid installations, and renewable energy systems. For detailed installation and operation instructions, refer to the official owner’s manual available online. Whether you need reliable backup power or scalable power systems, the Victron Quattro delivers performance, flexibility, and peace of mind.
