The Victron Quattro 24/3000/70-50/50 VE.Bus is a high-quality 3-in-1 inverter designed specifically for professional energy applications.
It combines a powerful pure sine wave inverter, an intelligent battery charger, and an automatic AC transfer switch in one compact unit—with two AC inputs for mains and generator operation.
With a continuous output of 3 kVA (approx. 2400 W), the Quattro delivers a pure and stable 230 V AC output voltage, ideal for sensitive electronics, tools, pumps, or household appliances.
The integrated charger provides up to 70 A charging current and ensures efficient and safe battery charging via a multi-stage, adaptive characteristic curve – regardless of the power source.
The dual AC inputs allow automatic prioritization between mains and generator operation. The Quattro switches seamlessly (< 20 ms) to battery operation when no external power source is available – perfect for systems that require uninterrupted power supply.
With Victron's intelligent PowerAssist and PowerControl functions, the Quattro can limit mains or generator loads and add battery power to support them when the total power demand briefly exceeds the available limit.
Thanks to VE.Bus communication, it can be fully integrated into Victron systems for monitoring, control, and remote access via GX devices or the VRM portal.
Multiple Quattro devices can be operated in parallel or in a 3-phase configuration to achieve higher power ratings or complex systems.
Its robust design, high efficiency, and universal applicability make it the ideal choice for boats, off-grid installations, and professional energy systems.
