Output Frequency 50 Hz 60 Hz DC DC Switching Controllers Supporting Permissible Grid Voltage Range 300 460 Volt Power Systems

Product Description:

The GREEF ENERGY multi-functional converter combines several essential functions into a single device. It performs AC-to-DC rectification specifically for permanent magnet (PM) generators, manages battery charging, and supports DC-to-AC inversion. Additionally, it includes a comprehensive energy management system to optimize power usage.

Equipped with a configurable dual LCD touchscreen, this converter employs advanced converter technology to deliver precise and stable control of voltage and frequency for Permanent Magnet Synchronous Generators (PMSGs). This ensures a continuous and reliable power supply to connected loads without interruption.

Moreover, the converter provides flexibility by allowing configuration for grid-tied operation. In this mode, it can synchronize with the utility grid to feed power back or charge batteries using grid energy, enhancing overall system efficiency and versatility.

Features:

The EMS smart energy management system offers multiple configurable operating modes to suit various energy needs. Users can select from off-grid, grid-tied, and grid charging modes, providing flexibility and adaptability for different power environments.

This system features a double LCD smart touch screen display, allowing for intuitive and user-friendly interaction. It also incorporates generator power curve tracking technology to optimize performance and efficiency.

For enhanced reliability, the EMS system supports AC/DC dual backup to provide auxiliary power supply. Additionally, it offers advanced control technology specifically designed to handle unbalanced loads effectively.

The system is equipped with a standard RS485 Modbus RTU protocol for seamless integration and communication with other devices. Optional features include PWM dump load protection against over-voltage and over-speed conditions, water gate motor control, and support for customized sensor control functions.

Remote monitoring and control is made easy with the availability of WiFi and LAN app connectivity (optional). Users can also integrate a static transfer switch (STS) for grid-tie and off-grid applications, enhancing the system's versatility and functionality.

Technical Parameters:

The ACPCS series includes multiple models designed to meet various power requirements, ranging from 100 kW to 500 kW. These models include ACPCS-100kt, ACPCS-150kt, ACPCS-200kt, ACPCS-250kt, ACPCS-300kt, and ACPCS-500kt. Each model is engineered with specific parameters for generator AC input, battery input, and output side characteristics to ensure optimal performance.

The rated power of the units ranges from 100 kW to 500 kW depending on the model. The rated AC input voltage is specified as at least 240 Vac, while the optimal generator rated voltage is around 450 Vac. Starting voltage should be equal to or greater than 180 Vac. The operational AC voltage range extends from 150 Vac to 550 Vac, allowing flexibility in varying input conditions. Maximum AC current values depend on the model, starting from 241 A for the 100 kW model and reaching up to 1203 A for the 500 kW variant.

All models utilize lithium-ion batteries with customizable voltage ranges to fit specific system needs. The rated battery voltage varies from 400 Vdc up to 900 Vdc, offering flexibility in design. Maximum charging and discharging currents also vary per model, with the smallest unit supporting up to 250 A and the largest handling currents as high as 750 A or 651 A, depending on the specific model configuration.

The rated charging and discharging power aligns closely with the rated power of the models, spanning from 100 kW to 500 kW. Maximum charge and discharge power capabilities can exceed rated levels, providing additional overhead - for example, the 100 kW model can handle up to 120 kW whereas the 500 kW model supports up to 600 kW. Rated currents on the output side range between 144 A and 433 A for charging/discharging, with maximum currents extending higher to handle transient conditions.

The grid voltage is standardized at 400 V with an allowable working range between 300 V and 460 V. The system supports both 50 Hz and 60 Hz frequencies, ensuring compatibility with various grid standards. Performance characteristics include a current total harmonic distortion rate below 3% at rated power, a power factor exceeding 0.99, and a power factor range spanning from -1 to 1. The devices are capable of handling an overload capacity of 1.2 times the rated power continuously for 1 minute.
