Product Description

Intelligent Air Cooling Power Curve Controller Funcion Suitable for Permissible Grid Voltage Range 300 460 in Energy Management 0

Product Description:

The GREEF ENERGY multi-functional converter combines several essential features into a single device. It supports AC-to-DC rectification specifically designed for Permanent Magnet (PM) generators, allowing efficient conversion of alternating current to direct current. In addition to this, the converter facilitates battery charging, ensuring that energy storage systems remain powered and ready for use.

This versatile converter also supports DC-to-AC inversion, enabling the transformation of direct current back into alternating current. This is particularly useful for supplying power to AC loads. Moreover, the integrated energy management system helps optimize the overall energy flow, improving efficiency and reliability in various applications.

Equipped with a configurable dual LCD touchscreen, the device offers an intuitive interface for monitoring and control. It employs cutting-edge converter technology to maintain stable voltage and frequency regulation for Permanent Magnet Synchronous Generators (PMSGs). This capability guarantees a consistent and uninterrupted power supply to connected loads.

Furthermore, the GREEF ENERGY converter can be easily reconfigured to operate in a grid-tied mode. This feature allows it to synchronize with the main electrical grid, enabling both operation and grid charging functions. Such flexibility makes the converter suitable for diverse energy systems and ensures smooth integration with existing infrastructure.


Features:

EMS Smart Energy Management System

The EMS smart energy management system offers multiple configurable operating modes, including off-grid, grid-tied, and grid charging options. This flexibility allows users to tailor the system to their specific energy requirements and operational preferences.

Equipped with a double LCD smart touch screen display, the system provides an intuitive and user-friendly interface. Users can easily monitor and control various parameters for optimal performance and convenience.

One of the advanced features of the system is the generator power curve tracking technology, which enhances the efficiency of power generation. Additionally, it supports AC/DC dual backup to ensure a reliable auxiliary power supply at all times.

The control technology is designed to handle unbalanced loads effectively, ensuring stability and safety across different usage scenarios. Communication is facilitated through a standard RS 485 Modbus RTU protocol, enabling seamless integration with other devices.

Optional features include a PWM dump load with protection against over voltage and over speed, as well as a water gate motor control function. For enhanced monitoring and control, a WiFi or LAN remote app is available.

Moreover, the system supports customized sensor control functions to meet various application needs. It can also integrate an optional Static Transfer Switch (STS) for both grid-tie and off-grid applications, providing additional flexibility and reliability.

Applications:

Wind Turbine, Solar, and Hydro Systems

Renewable energy technologies have become increasingly vital in today’s world as sustainable alternatives to fossil fuels. Among the prominent sources are wind turbines, solar panels, and hydroelectric systems, each harnessing natural forces to generate clean power.

Wind turbines convert the kinetic energy of wind into electricity. By capturing the wind’s movement through large blades, these systems provide a reliable source of energy, especially in windy regions. Their scalability allows them to power anything from small homes to large industrial complexes.

Solar energy systems make use of sunlight to produce electricity via photovoltaic cells. These systems are highly versatile and can be installed on rooftops, open fields, or integrated into building materials, making solar power accessible to a wide range of applications.

Hydroelectric systems utilize the flow of water to generate energy. By directing water through turbines, these systems transform potential and kinetic energy into electricity. Hydropower remains one of the oldest and most efficient forms of renewable energy, especially in areas with abundant water resources.

My farm is 30 kilometers from town, and connecting to the power grid would cost a fortune. Three years ago, I installed a solar panel system with a battery bank. It was sufficient during spring, summer, and fall, but in winter, we often had a week of consecutive overcast days—and the batteries would run out in just three days. Last year, I decided to add a variable-pitch wind turbine, connected it to the AC coupling port of the Deye inverter, and set up a hybrid solar-wind system. Throughout the entire winter, the battery level never dropped below 45%, and I never had to work in the dark again. The Deye app allows me to monitor both the solar and wind turbine data simultaneously, and the transition between them is so smooth it’s almost imperceptible. Relying solely on solar power during winter on a Nordic farm is a gamble. Only by combining a variable-pitch wind turbine with a Deye inverter—creating a wind-solar hybrid system—can you get through the winter with peace of mind.

I run a small dairy farm in northern Norway, far from the power grid. A few years ago, I installed solar panels and a Deye inverter, but the solar system basically stops working in winter, and the diesel generator was costing me a fortune. This year, I added this variable-pitch wind turbine and connected it to the Deye inverter for a hybrid solar-wind system, and we haven’t had a single power outage all winter. This wind turbine starts up at low wind speeds of just 2–3 on the Beaufort scale. During blizzards, the blades automatically pitch down to slow the turbine, preventing runaway speeds, and it’s much quieter than my neighbor’s fixed-pitch model. The Deye inverter’s switching logic is smart—it prioritizes solar power when available, and automatically switches to the wind turbine when solar output drops. It’s all clearly visible on the app. Now, the diesel generator is practically idle. Wind and solar backing each other up—that’s true off-grid freedom.

“I built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
