The GREEF ENERGY multi-functional converter combines several key functionalities into a single unit. It supports AC-to-DC rectification for permanent magnet generators (PM generators), battery charging, and DC-to-AC inversion. Additionally, it incorporates a comprehensive energy management system to optimize power flow and usage.
Equipped with a configurable dual LCD touchscreen, this converter offers user-friendly control and monitoring. It employs advanced converter technology to maintain stable voltage and frequency regulation for permanent magnet synchronous generators (PMSGs), ensuring a continuous and reliable power supply to connected loads.
Moreover, the device can be configured to operate in a grid-tied mode, allowing it to synchronize with the utility grid. This feature enables both grid operation and grid charging, providing greater flexibility and efficiency in energy management.
The generator operates with a rated power of 100 kW and requires a minimum rated voltage of 320 Vac. The optimal rated voltage for the generator is 450 Vac, while the AC voltage working range spans from 240 to 550 Vac. The maximum allowable AC current is 180 A.
The system uses a Lithium-ion battery with a voltage range between 350 and 450 Vdc. The rated battery voltage is set at 400 Vdc. The battery supports a maximum charging and discharging current of 250 A.
For grid-connected operation, the rated charging and discharging power is 100 kW, with a maximum capacity of 120 kW. The rated charging and discharging current is 144 A, with a maximum current allowable of 173 A. The rated grid voltage is 400 V, and it can tolerate a voltage range from 300 to 460 V. The rated grid frequency supports both 50 Hz and 60 Hz.
The current total harmonic distortion at rated power is less than 3%, and the power factor is greater than 0.99, with a range from -1 to 1. The system can handle an overload capacity of 1.2 times the nominal power continuously for one minute.
When operating off-grid, the rated input voltage is 400 V with a voltage deviation of ± 2%. The total harmonic distortion rate under linear load conditions remains below 3%.
The system includes optional over-voltage and speed protection. It supports AC short-circuit protection and AC output overcurrent protection. Surge protection is provided at Level 2.
The generator reaches a maximum efficiency of 95%. Its topology consists of an AC-DC rectifier, a DC-DC buck-boost converter, and a DC-AC inverter, integrated with an Energy Management System (EMS). The operating ambient temperature ranges from -40℃ to 60℃, and the protection level is rated at IP54.
The display provides various pieces of information, including generator speed (rpm), input voltage (Vdc), input current (Vac), output power (kW), grid voltage (Vac), grid current (A), and energy generated today, this month, last month, this year, and last year. It also allows for power curve settings. Cooling is managed through an intelligent air cooling system.
The maximum operating altitude is 4,000 meters, with power derating applied when exceeding 3,000 meters. Standby power consumption is less than 50 W. The display is an LCD SMART Touch Screen, and communication modes include Ethernet, RS485, and WIFI.
The equipment measures 1500 mm in height, 1500 mm in width, and 1300 mm in depth. The weight, excluding any dump load, is less than or equal to 600 kg.
The GREEF ENERGY multi-functional converter is a versatile and highly adaptable system designed to meet the demands of various applications, especially those requiring reliable and intelligent power management. Its design emphasizes flexibility, making it suitable for a broad spectrum of uses.
One of the primary applications of this converter is in renewable energy systems. It is particularly effective for integrating Permanent Magnet Synchronous Generators (PMSGs), which are commonly used with wind turbines or hydro turbines. This integration enables stable AC power delivery for off-grid or hybrid power setups, ensuring a consistent energy supply for different loads.
In off-grid and backup power scenarios, the GREEF ENERGY converter functions as a central unit for power conversion and management. It is ideal for standalone systems such as remote locations, cabins, or telecom stations. The system manages input from generators, controls battery charging processes, and governs inverter output, providing a seamless power solution.
For grid-interactive applications, the converter can be configured to operate in a grid-tied mode. This allows batteries to be charged from the grid and, depending on local regulations and settings, may enable the feeding of surplus power back into the grid. This functionality enhances energy efficiency and supports sustainable energy practices.
In industrial and commercial environments, the device caters to the need for a stable power supply even under unbalanced load conditions. It offers remote monitoring capabilities through WIFI or LAN connections and supports integration with building management systems via the Modbus protocol, facilitating comprehensive power management.
Additionally, the GREEF ENERGY converter provides specialized control features tailored for unique requirements. Examples include water gate motor control for micro-hydropower plants and the option to incorporate a Static Transfer Switch (STS) to ensure smooth transitions between grid and off-grid power sources.
Overall, this product serves as a core platform that integrates power generation, energy storage, consumption management, and grid-tie functionalities. Its modular and configurable nature allows for flexible deployment across diverse and complex scenarios, ranging from residential off-grid energy storage systems and commercial backup power setups to small-scale renewable energy power plants.
