The Victron Quattro-II 24V 3kVA 2x120V Inverter 70A Charger

Unlock the full potential of your power supply with the Victron Quattro-II 24V 3kVA 2x120V Inverter/Charger, a state-of-the-art combined inverter and charger designed specifically for standard North American 50A 120/240VAC split-phase applications. Building upon the success of the MultiPlus-II 2x120V, the Quattro-II 24V takes power management to new heights, providing seamless integration of shore power and generator inputs with a host of cutting-edge features.

Seamless Dual AC Input Integration

Whether you’re connected to shore power or running on a generator, the Quattro-II 24V can handle it all. This advanced system accepts and passes through both lines of a 120/240V supply, allowing you to utilize the full 50A for charging and AC loads. When connected to a single-phase 120V supply, it intelligently combines the L1 and L2 outputs, ensuring that each line receives a steady single-phase 120V power.

Inverter Mode for Uninterrupted Power

In the absence of AC sources, the Victron Quattro-II 24V swiftly switches to inverter operation. Delivering a single-phase 120V output, it internally connects both lines (L1 and L2) to provide seamless power supply to loads on either output. This innovative feature ensures that your distribution panel receives uninterrupted 120V power, regardless of the connection circumstances.

Safeguarding Your System

The Quattro-II 24V can also prevent potential issues caused by heavy loads on the battery. While both sides of your distribution panel receive 120V power in all connection scenarios, 240VAC is only available when the Quattro is supplied by a split-phase 120/240VAC source. This safeguard prevents high-consumption appliances like water heaters or 240V air conditioners from discharging the battery.

Feature-Rich and Versatile

The Quattro-II 24V boasts an array of impressive features that cater to various power needs and scenarios. Some of the highlights include:

  • PowerControl and PowerAssist: Ensure maximum utilization of available power resources and seamless assistance from external sources when needed.
  • Input Current Limit: Safeguard your system against excessive loads from external AC sources.
  • Multiple AC Outputs: Enjoy the convenience of having two AC outputs for greater flexibility in your power distribution.
  • Parallel and 3-Phase Configuration: For larger capacity VE.Bus systems, the Victron Quattro-II 24V offers seamless parallel and 3-phase configuration options.
  • LiFePO4 Battery Compatibility: The Quattro-II 24V is suitable for LiFePO4 batteries and various other battery types.

Reliable and Rugged Design

The Victron Quattro-II 24V is engineered for both durability and performance, housed in an IP22 rated enclosure. With a wide operational temperature range from -40 to 150°F, it can withstand diverse environmental conditions.


Current Connected updates inverters with the latest firmware (as of order date) and custom programs them for LiFePO4 (US customers only). For any additional config customization please let us know in your order notes.
