The Quattro 12/3000/120-50/50 hybrid inverter — is the true flagship among Victron Energy's hybrid inverters. Designed for professional industrial applications, it is capable of delivering up to 3,000 VA of power with a built-in 120 A charger, two independent AC inputs, and full support for standalone, hybrid, and grid-connected energy storage systems (ESS).
This device is a key component in projects where critical uninterruptible power supply, scalability, and safety when working with LiFePO₄ batteries are of paramount importance.
Three-phase configurations are often used, consisting of three 400V 45kVA / 36 kW, or systems with 6, 9, and 12 inverters to achieve a total power of 90 kVA/72 kW, 135 kVA/108 kW, and 180 kVA/144 kW, respectively.
Key advantages of the Quattro 12/3000/120-50/50 inverter
- Power: 3,000 VA / 2,400 W, peak — up to 6,000 W.
- Two independent AC inputs with built-in intelligent ATS — automatic switching between the grid and the generator.
- Each AC input supports its own PowerControl and PowerAssist — ideal when operating with a generator of lower power than the grid.
- Two AC outputs – AC-1 is guaranteed with power from the battery/FEM, AC-2 is secondary with power only from the grid/generator/FEM.
- 50 A or 11 kW transfer power – when operating from the grid, the inverter has a power rating of 11 kW, allowing you to connect any combination of loads on the line without worrying about overloading the inverter.
- High efficiency up to 93%, stable operation under heavy load.
- True sine wave — power any equipment without compromise.
- 120 A charger — supports all common types of 24V rechargeable batteries and is adjustable over a wide range from 9.5 to 17 volts, ideally suited for LiFePO4 packs with 15 or 16 cells.
- Support for LiFePO₄ batteries with VE.Bus or VE.Can data exchange — safe and reliable integration.
- Industrial housing, IP20 protection, aluminum, operating range from –20 to +60°C.
- Scalability up to 28.8 kW / 36 kVA — up to 12 units in a three-phase system.
Technical Features
Two AC inputs with integrated automatic transfer switch (ATS)
- The Quattro can be connected to two AC sources simultaneously: for example, grid + generator, two generators, or grid + grid.
- Automatically switches to the active source based on priority
- Extremely fast switching (less than 4–20 ms)
- Operates as an intelligent ATS, fully integrated into the inverter
- Each input has its own current limit settings (PowerControl)
- PowerAssist allows you to compensate for power shortages with a battery
Ideal for solar systems
- Solar energy — Quattro’s natural element. Works in:
- Off-grid systems
- ESS with MPPT or grid-connected PV inverters
- Standby or real-time solar consumption modes
- Thanks to the VE.Bus interface, it is easily configurable via Cerbo GX or VE.Configure and adapts to any type of solar system.
Professional ESS logic
Supports:
- self-consumption from PV
- backup in case of a power outage
- charge at night – discharge during the day (by timer or tariff)
- flexible scenarios via Victron Assistants or VRM
LiFePO₄ support – data exchange with BMS
The Quattro 24/3000/120-50/50 is designed with modern lithium batteries (LiFePO₄) in mind, which transmit data via: VE.Bus, VE.Can, BMS-Can, providing:
- Intelligent charge/discharge control
- Protection against overheating, overcharging, and overvoltage
- Accurate SOC and temperature monitoring
- Maximum safety and system lifespan
Use Cases
- Industrial facilities – where power and continuity are required.
- Business centers, medical facilities – backup for critical areas.
- Large hybrid and standalone solar power stations.
- High-consumption private estates – stable energy.
- Mobile service stations and containers – reliability on the move.
- Telecom and data centers – uninterrupted power supply for infrastructure.
Complies with the ECE R10-5 electromagnetic compatibility (EMC) standard
ECE R10-5 – is an electromagnetic compatibility (EMC) standard applicable to electronic equipment used in vehicles. It regulates requirements for electromagnetic interference emissions and immunity to external electromagnetic influences.
What does ECE R10-5 certification mean for Victron Energy inverters?
Low level of electromagnetic emissions
- The inverters do not generate radio frequency interference that could affect radio communications, GPS, mobile networks, or other electronic systems in cars, yachts, or industrial equipment.
High resistance to electromagnetic interference
- The inverters operate reliably even under challenging conditions where sudden voltage fluctuations or strong electromagnetic fields may occur (e.g., in trucks, buses, and heavy equipment).
Safe integration into transportation systems
- Complies with the requirements of the United Nations Economic Commission for Europe (ECE), allowing the inverters to be used in cars, campers, marine vessels, and other vehicles without the risk of negatively affecting the head unit’s electronic systems or vehicle safety systems such as ABS.
Quality assurance and compliance with international standards
- Compliance with ECE R10-5 confirms that Victron Energy products have undergone rigorous testing and meet international safety requirements for use in transportation.
What does this mean for users of Inverter Smart inverters?
- Legal use in vehicles without the need for additional certification.
- Compatibility with other electronic systems – the inverter does not interfere with radio, navigation, autopilot, GPS, or other electrical devices.
- Stable operation in challenging conditions – marine vessels, RVs, commercial vehicles, and special-purpose equipment.
- Protection against electromagnetic interference – the inverter does not fail during sudden voltage fluctuations.
Communication interfaces
- VE.Bus – Parallel/three-phase operation, connection to GX controllers, configuration
- USB / RS232 (via MK3-USB) – Configuration via VE.Configure / VictronConnect
- VE.Bus Smart Dongle – Monitoring and control via Bluetooth
- GX Controller – Extends the inverter’s functionality with VE.Can and VE.Direct ports, Ethernet, Bluetooth, WiFi, and USB, allowing the system to connect to the internet, the VRM cloud service, including all other system modules (MPPT controllers, current shunts, LiFePO4 batteries with BMS), and all of this is very convenient to configure, control, and monitor directly from your phone anywhere in the world).
