Applications
The GREEF ENERGY multi-functional converter provides a versatile and adaptable solution for diverse power management requirements. It excels in applications demanding reliable and intelligent energy system control, making it essential for modern energy infrastructures.
Primary applications include renewable energy systems integration with Permanent Magnet Synchronous Generators (PMSGs) for wind and hydro turbine setups, supporting off-grid or hybrid power frameworks with stable AC power delivery.
For off-grid and backup power applications, the converter serves as the central hub for power conversion and system management in remote locations, cabins, telecommunications sites, and standalone installations.
Grid-interactive operation enables battery charging from the grid and, where permitted, feeding surplus electricity back to the grid, enhancing power flow management flexibility.
Industrial and commercial environments benefit from reliable power under unbalanced load conditions, with remote monitoring via WIFI/LAN and Modbus protocol integration with building management systems.
Specialized control options include water gate motor control for micro-hydropower plants and Static Transfer Switch (STS) for smooth grid/off-grid transitions.
This comprehensive platform consolidates power generation, storage, consumption management, and grid integration capabilities for flexible deployment across residential off-grid systems, commercial backup solutions, and small-scale renewable energy plants.
