The GREEF ENERGY multi-functional converter combines several essential functions into one device. It performs AC-to-DC rectification specifically designed for permanent magnet (PM) generators, supports battery charging, and facilitates DC-to-AC inversion. Additionally, it includes an integrated energy management system to optimize overall performance.
Equipped with a dual LCD touchscreen that can be customized according to user requirements, the converter employs advanced technology to maintain stable voltage and frequency control for permanent magnet synchronous generators (PMSGs). This ensures a continuous and reliable power supply to connected loads without interruption.
Furthermore, the converter offers flexibility by allowing configuration for grid-tied operation. In this mode, it can seamlessly switch to connect with the electrical grid, enabling grid charging and synchronized performance with the utility supply.
The EMS Smart Energy Management System is designed to provide efficient and versatile control over energy use. It supports multiple configurable operating modes to suit different power needs, including off-grid, grid-tied, and grid charging options. This flexibility ensures that users can optimize their energy management based on their specific requirements.
The system features a double LCD smart touch screen display, offering an intuitive interface for easy monitoring and control. Additionally, it incorporates advanced generator power curve tracking technology to maximize generator efficiency and performance.
To enhance reliability, the EMS system includes AC/DC dual backup for auxiliary power supply. It also offers advanced control technology specifically designed to manage unbalanced loads effectively, ensuring stable and consistent power delivery across various applications.
Communication and integration are streamlined through the standard RS-485 Modbus RTU protocol, facilitating seamless connectivity with other devices and systems. Optional features include a PWM dump load protection function that safeguards against over-voltage and over-speed conditions, as well as a water gate motor control function to support specialized operational needs.
For enhanced convenience, the EMS system supports remote monitoring and control via WiFi or LAN through a dedicated app. Users can also benefit from customized sensor control functions tailored to specific applications. Additionally, the system allows for the integration of a Static Transfer Switch (STS), which provides seamless switching between grid-tied and off-grid configurations, improving overall system resilience and flexibility.
