Whether you’re embracing an off-grid lifestyle, preparing for emergencies, or seeking greater energy independence, the Quattro is your trusted companion for consistent and efficient power supply.

Reliable and Efficient Power Management

  • True Sine Wave Inverter: Enjoy clean and stable power for your sensitive electronics, ensuring their smooth operation and longevity.
  • Adaptive Charging: The Quattro optimizes battery charging, intelligently adjusting the charging process based on the battery’s condition and state of charge.
  • Hybrid PowerAssist Technology: With this innovative technology, the Quattro can supplement limited AC sources, such as generators or shore power connections, by utilizing power from the battery bank. This prevents overloading and ensures a consistent power supply.

Unmatched Flexibility and Integration

  • Dual AC Inputs: Connect your Victron Quattro 48V 5kVA Inverter to two independent AC sources, such as shore-side power and a generator, or two generators. The Quattro automatically connects to the active source, providing you with a seamless and uninterrupted power supply.
  • No-Break Functionality: In the event of a grid failure or disconnection of shore or generator power, the Quattro swiftly takes over the supply to your connected loads. This ensures that critical devices like computers and electronics continue to operate without any disruption.
  • Additional Output for Specific Loads: The Quattro features a second output that is live only when AC power is available on one of its inputs. This output is ideal for devices that should not discharge the battery, such as air-conditioning units or water heaters.

Expandable Power with Parallel Operation

Both three-phase and split-phase opperation are supported by the Victron Quattro 48V 5kVA Inverter. Still need more power? You can also connect up to six Quattros in parallel, enabling you to achieve higher power output.

Advanced Monitoring and Control

  • GX Device Compatibility: When combined with a GX device like the Cerbo GX, you gain comprehensive control and monitoring capabilities. Whether you’re on-site (LAN) or remotely accessing the system via the internet, the free VRM app and VRM portal website allow you to manage and monitor your Quattro from anywhere in the world.
  • Total System Control: Adjust settings, monitor energy usage, and even automate backup generator startup through a phone, tablet, laptop, or PC. With the Victron Quattro 48V 5kVA Inverter and the GX device, the level of control is limitless.

Please login to post questions


Does PV to battery charging function work while unit is in "search mode" drawing only 15w?



The PV function is not handled by this Quattro inverter, rather it would be handled by the solar controller that operates independently of the inverter entirely. This means that the inverter can be completely powered off or in the power-save mode and solar would still be able to charge the batteries.


Can a single SOK 48V 100Ah battery power this inverter or will i need to create a parallel connection with 2 or more?



One battery is meeting the absolute bare minimum, however, if you use the surge capacity of the inverter, it will likely cause the battery to go into overload.
