A nationally recognized high-tech enterprise dedicated to advanced energy control and grid-tied systems.
Founded in 2004, Jinan Deming Power Equipment Co., Ltd. is a nationally recognized high-tech enterprise specializing in the research, development, production, and service of renewable energy power equipment and advanced power testing solutions. Holding the ISO9001:2015 certification, the company has consistently been recognized as a high-tech enterprise by the Chinese government (2015, 2018), serving as a benchmark for quality and engineering excellence in the clean energy industry.
Our dedicated R&D team consists of 16 highly skilled engineers, including doctoral supervisors and master's degree holders. We firmly believe that innovation is the core driver of growth. Consequently, we invest no less than 20% of our annual sales revenue into technology development. Over the last three years alone, Deming has successfully completed 17 R&D projects, turning 16 scientific and technological achievements into commercialized products. Our main products include advanced wind/solar controllers, high-performance inverters, frequency converters, and high-power bidirectional DC test power supplies ranging from 150kW to 500kW.
Deming's products have been exported to 120+ countries and regions, including Germany, Japan, the United States, UK, Canada, Australia, and Brazil. Our commitment to reliability and engineering capability has allowed us to establish solid cooperative relationships with Fortune 500 enterprises. As a primary wind power on grid wind turbine inverter exporter, we are positioned to support global partners in their green energy transitions.
Jinan Deming Power Equipment provides grid-tied wind controllers and hybrid systems that match strict international standards. By integrating MPPT technology, custom voltage stabilization, and reliable dump load protection, our systems ensure grid stability, minimized THD (Total Harmonic Distortion), and optimal conversion efficiency for onshore and offshore wind generation applications.
Advanced assembly lines, automated component verification, and comprehensive reliability testing facilities.
Every step of our manufacturing is subject to rigorous inspections, from initial copper bar layout to final calibration.
We leverage international test benches to ensure zero-defect shipment of high-capacity grid-tied wind controllers.
Our custom hardware configurations are developed via advanced software simulation to meet site-specific power parameters.
Deep-dive into the control topologies, safety algorithms, and grid compliance standards for modern wind generators.
Maximum Power Point Tracking (MPPT) optimizes the aerodynamic efficiency of wind blades by dynamically adjusting generator RPM relative to real-time wind speed. Pulse Width Modulation (PWM) offers stable voltage regulation, serving as an active brake and over-speed dump load system during high-velocity gusts.
Unlike solar panels, wind turbines cannot simply be open-circuited under grid failures. Deming's grid-tie wind controllers incorporate a heavy-duty, automatically engaged resistor dump load. This load prevents mechanical runaway and protects the electrical components from voltage surges if grid connection is lost.
Our inverters meet local utility specifications by supporting LVRT. They remain online during momentary grid disturbances, supplying reactive power to stabilize the distribution network rather than triggering immediate shutoff and compounding utility grid instability.
Grid integration of wind power requires managing fluctuating mechanical energy input and converting it into highly stable, synchronized AC electricity. Because wind speed varies continuously, a specialized wind turbine inverter must handle a highly variable rectifying DC input voltage. Deming's range of grid-tie wind generator controllers (FKJ-GT series from 2kW to 100kW+) manages this by combining a three-phase rectifier, dynamic PWM brake, and integrated dump load controller into a single unit. This integrated approach minimizes cable routing, cuts installation costs, and eliminates impedance mismatches between independent modules.
For hybrid installations, our solar-wind hybrid controllers process inputs from photovoltaic arrays and wind turbines simultaneously. In these systems, solar energy provides steady daytime power, while wind input delivers power during off-peak night hours. The controller coordinates both sources to optimize feed-in tariffs and local power self-consumption.

Sourcing from China-based manufacturers like Jinan Deming Power Equipment provides key advantages for project developers, utilities, and commercial distributors worldwide:
Key growth drivers, technical developments, and global compliance demands shaping wind energy distribution systems.
The global energy sector is shifting rapidly toward decentralization, highlighting the importance of distributed wind generation. In remote locations, island communities, and agricultural operations, standard utility grids can be unreliable or nonexistent. Utilizing a distributed wind system paired with an on-grid wind turbine inverter allows facilities to harvest wind energy locally, offset utility costs, and feed excess clean power back into the grid.
Procurement teams today demand complete systems that comply with global grid-tie certifications, such as IEEE 1547 in the Americas and VDE-AR-N 4105 in Europe. These standards demand strict control over harmonic currents, rapid anti-islanding protection (which automatically disconnects the inverter when the utility grid goes down to protect service crews), and reliable operation under harsh conditions. Jinan Deming Power Equipment works directly with global engineers to optimize these settings at the factory, ensuring smooth local commissioning and regulatory approvals.
