Product Description

The EcoFlow FlowMaster Generator Rectifier is a purpose built solution for converting generator based AC power into stable and efficient DC power for charging EcoFlow DELTA Pro Ultra X systems. Designed to support demanding whole home and backup energy applications, this rectifier allows seamless integration between traditional portable generators and modern battery based power systems. By delivering clean DC output, it helps protect connected equipment while maintaining consistent charging performance.

At the core of the EcoFlow FlowMaster Generator Rectifier is its ability to accept AC input from most portable gasoline generators rated up to 12 kilowatts. Instead of relying on fluctuating AC signals, the unit converts incoming power into regulated DC output optimized for the DELTA Pro Ultra X. This design removes the need for soft starters or additional power conditioning equipment, simplifying system design and improving overall reliability.

Designed for High Power Backup Systems

Modern backup power systems require both flexibility and stability. The EcoFlow FlowMaster Generator Rectifier is engineered to meet these needs by delivering continuous output suitable for extended operation. Its 12 kilowatt continuous DC output supports large scale energy storage charging, making it ideal for homes, workshops, and professional installations where reliable power availability is essential.

Compatibility is a major advantage of this rectifier. It works with a wide range of portable gasoline generators, allowing users to select equipment based on availability and fuel preferences rather than restrictive electrical requirements. When paired with EcoFlow DELTA Pro Ultra X components, the rectifier ensures efficient energy transfer without unnecessary losses or interruptions.

Performance and Reliability

Consistency is critical when charging high capacity battery systems. The EcoFlow FlowMaster Generator Rectifier provides stable DC conversion that helps maintain battery health and charging efficiency. By smoothing out voltage fluctuations commonly associated with generator output, it reduces stress on connected systems and contributes to longer service life.

The plug and play design makes installation straightforward. Users can integrate the rectifier into their power setup without complex wiring or configuration. This simplicity is especially valuable during emergency situations where rapid deployment is required. Once connected, the rectifier operates automatically, allowing the generator and battery system to work together seamlessly.

Whole Home and Emergency Power Use

For homeowners building a resilient energy solution, the EcoFlow FlowMaster Generator Rectifier plays a critical role. It bridges the gap between fuel powered generators and advanced battery systems, allowing both to work together efficiently. During extended outages, users can run a generator as needed while maintaining clean DC charging for their battery storage, reducing fuel consumption and improving overall system control.

In professional or remote environments, the rectifier enables flexible energy planning. Generators can be used as a primary or supplemental power source, while the DELTA Pro Ultra X handles load management and distribution. This combination provides reliable power without the instability often associated with direct generator connections.
