GREEF ENERGY's multi-functional converter combines several key capabilities into a single device. It performs AC-to-DC rectification specifically designed for permanent magnet generators (PM generators), supports battery charging, and handles DC-to-AC inversion efficiently. Additionally, it incorporates a comprehensive energy management system to optimize performance.

Equipped with a dual LCD touchscreen that can be customized according to user preferences, this converter leverages cutting-edge converter technology. This allows it to maintain stable voltage and frequency control when working with permanent magnet synchronous generators (PMSGs), ensuring a continuous and reliable power supply to connected loads.

Moreover, the converter offers flexibility by enabling configuration for grid-tied mode operation. In this mode, it can seamlessly switch to work in conjunction with the electrical grid, also supporting grid charging functionalities as needed. This makes it a versatile solution for diverse energy management scenarios.

The EMS smart energy management system offers multiple configurable operating modes to suit various energy needs. These modes include off-grid, grid-tied, and grid charging, providing flexible solutions for different power scenarios.

Equipped with a double LCD smart touch screen display, the system allows for easy monitoring and control. It features advanced generator power curve tracking technology to optimize performance and efficiency.

For enhanced reliability, the system supports AC/DC dual backup as an auxiliary power supply. It also incorporates control technology designed specifically for unbalanced loads, ensuring stable and consistent energy management.

Connectivity is enhanced with the standard RS-485 Modbus RTU protocol, facilitating seamless integration with other devices and systems. Optional functions include a PWM dump load protection mechanism for over voltage and over speed, as well as a water gate motor control feature.

Remote monitoring and control are made possible through an available WiFi/LAN app, offering convenient access from anywhere. Additionally, the system supports customized sensor control functions and the integration of a Static Transfer Switch (STS) for both grid-tie and off-grid applications, available as optional upgrades.

The rated power of the system is 100 kW. It operates at a rated voltage of at least 320 Vac, with an optimal generator rated voltage of 450 Vac. The acceptable AC voltage working range spans from 240 Vac up to 550 Vac. The maximum AC current supported is 180 A.

This system utilizes a lithium-ion battery type, with a voltage range from 350 Vdc to 450 Vdc. The rated battery voltage is set at 400 Vdc. The maximum charging and discharging current can reach up to 250 A.

When connected to the grid, the system has a rated charging and discharging power of 100 kW, with a maximum charge and discharge power of 120 kW. The rated charge and discharge current is 144 A, while the maximum charge-discharge current can be as high as 173 A.

The rated grid voltage is 400 V, with a permissible grid voltage range between 300 V and 460 V. The system supports grid frequencies of 50 or 60 Hz. The total harmonic distortion rate of the current at rated power is below 3%. Additionally, the power factor is greater than 0.99, with an adjustable range from -1 to 1. Overload capacity allows for 1.2 times the nominal power continuously for one minute.

In off-grid mode, the rated input voltage remains at 400 V, with an allowable voltage deviation of ±2%. The total harmonic distortion rate with linear loads is kept under 3%.

Protection features include optional overvoltage and speed protection, supported AC short-circuit protection, AC output overcurrent protection, and Level 2 surge protection.

The GREEF ENERGY multi-functional converter is a versatile and highly adaptable system designed to cater to a broad spectrum of applications, especially where dependable and intelligent power management is essential. Its design supports efficient integration and control, making it a reliable choice for various power-related needs.

One of the primary uses of this converter is in Renewable Energy Systems . It is particularly effective for incorporating Permanent Magnet Synchronous Generators (PMSGs) derived from renewable sources like wind turbines or hydro turbines. This allows the creation of off-grid or hybrid power systems that deliver stable alternating current (AC) power to connected loads.

In Off-Grid & Backup Power scenarios, the converter acts as the central hub for power conversion and management. It is ideal for standalone setups such as remote sites, cabins, or telecom stations. The device manages inputs from generators, battery charging processes, and inverter outputs, ensuring continuous and reliable power availability.

For Grid-Interactive Systems , the converter can be configured to operate in grid-tied mode. This enables the system to charge batteries from the grid and, where regulations and settings permit, feed surplus power back into the grid, enhancing energy efficiency and sustainability.

Moreover, in the context of Industrial & Commercial Power Management , the converter provides stable power supply solutions even under unbalanced load conditions. It supports remote monitoring through WIFI or LAN connections and can be integrated with building management systems via the Modbus protocol, facilitating comprehensive energy management.

The system also includes Specialized Control Functions tailored to particular applications. Examples include controlling water gate motors for micro-hydropower plants or embedding a Static Transfer Switch (STS) to ensure seamless switching between grid and off-grid power sources.

Overall, the GREEF ENERGY multi-functional converter serves as a fundamental platform that integrates power generation, storage, consumption management, and grid-tie capabilities. Its modular and configurable architecture allows flexible deployment across diverse and complex scenarios, from residential off-grid energy storage and commercial backup power to small-scale renewable energy power plants.
