Explore our leading range of high-efficiency three-phase converters, off-grid industrial inverters, and heavy-duty MPPT charge controllers designed for utility-scale energy projects.
Established 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 prestigious ISO9001:2015 certification, the company has been recognized as a high-tech enterprise by the Chinese government multiple times (2015, 2018).
With a dedicated R&D team of 16 engineers including doctoral supervisors and master's degree holders, Deming invests no less than 20% of annual sales revenue into technology development. Over the last three years, the team has completed 17 R&D projects, with 16 scientific and technological achievements transformed into commercial products.
Our specialized portfolio ranges from 150kW to 500kW, covering high-power bidirectional DC test power supplies, battery simulators, frequency converters, wind/solar controllers, and grid-forming inverters. Deming's products are widely exported to over 120+ countries—including Germany, Japan, the United States, UK, Canada, Australia, and Brazil—establishing strategic cooperative relationships with Fortune 500 enterprises.
Empowered by senior academic R&D specialists, our design phase leverages advanced CAD engineering and simulations to assure rugged industrial lifespans under volatile operating conditions.
Serving high-profile markets in North America, Western Europe, and East Asia, complying with stringent localized grid codes and electrical safety certifications.
A history of technical synergy with international grid integrators and utilities to develop customized MW-scale energy storage and distribution hardware.
The global transition toward carbon neutrality is driving significant advancements in photovoltaic (PV) generation and grid integration. As solar energy moves from auxiliary generation to base-load power, the solar manufacturing and export sectors are adapting to key paradigm shifts:
Transitioning from traditional 1000V systems to 1500V topologies. Higher operating voltages reduce DC-side losses, minimize cabling costs, and optimize total system efficiency, necessitating robust and highly insulated PCS inverters and charge controllers.
Modern microgrids require energy systems to function both as sinks and sources. Deming’s bidirectional PCS converters enable seamless battery simulation, grid charge-back, and dynamic peak shaving for industrial facilities.
With massive amounts of fluctuating solar and wind energy feeding the grid, grid-forming inverters are critical. They active-stabilize voltage and frequency, offering virtual inertia and black-start capabilities in remote zones.
Enterprise buyers, grid operators, and EPC developers face distinct bottlenecks when sourcing power conversion hardware. Deming mitigates these challenges through tailored engineering and rigorous quality verification:
A minor 0.5% shift in conversion efficiency translates to thousands of dollars in lost power over a project's lifespan. Our 200kW AC/DC converters deliver a documented 99% conversion efficiency, ensuring rapid payback periods and low operational costs.
Solar and wind plants operate in high-temperature, humid, or high-altitude locations. Deming’s products feature optimized cooling systems, anti-corrosion enclosures, and thermal management circuits designed to operate reliably in desert, marine, or high-altitude microgrids.
Integrating non-compliant power hardware can lead to project delays or grid interconnection rejection. We design and test equipment in compliance with critical international standards, including CE, VDE, and UL guidelines, ensuring seamless integration.
Standard solutions often fall short of unique facility configurations. Deming provides customized input voltage windows (e.g., 700V/800V/850V DC lines) and specialized triple-output configurations to match specific wind, solar, or battery bank arrays.
Utility-scale and commercial & industrial (C&I) sectors require integrated, modular solutions rather than isolated components. Jinan Deming Power Equipment provides engineered systems that solve microgrid challenges globally:
Our bidirectional converters (PCS) serve as the vital link between massive battery arrays and the AC grid. Integrating an isolation transformer ensures complete galvanic protection, shielding expensive lithium or flow batteries from transient grid surges.
By combining solar arrays, wind turbines, and energy storage, our hybrid MPPT and PWM charge controllers ensure stable power output even during low irradiance or zero-wind conditions. This setup provides stable energy for remote mining, offshore operations, and rural electrification.
Our marine shore power converters facilitate static frequency conversion (e.g., 50Hz to 60Hz), matching harbor distribution grids with vessel electrical networks. This configuration eliminates diesel emissions in port zones and complies with marine environmental policies.
To maintain our industry-leading quality standards, every product undergoes a comprehensive quality control cycle. Below is a tour of our ISO9001-certified factory, depicting the production and high-precision testing phases.

International deployment requires local compliance and accessible technical support. At Jinan Deming, we back our high-power converters and controllers with strong service networks and strict conformity checks:
Our engineers partner with global installers to offer commissioning support, on-site diagnostics, and custom software adjustments for regional grid conditions.
Every product is certified to verify clean harmonics, precise voltage tracking, and immediate anti-islanding protection in line with international grid requirements.
By keeping core processes in-house—from PCB layout design to copper bar production—we maintain consistent lead times and trace all critical components.
As renewable energy needs grow, Jinan Deming is committed to next-generation power electronics. Our R&D team works to push the boundaries of high-power converters and energy management:
Silicon Carbide (SiC) Integration: We are transitioning to wide-bandgap SiC semiconductors in our high-power inverters. SiC enables faster switching speeds, reduced heat generation, and even smaller footprints, helping us achieve conversion efficiencies beyond 99.2%.
AI-Powered Intelligent Energy Control: Our upcoming line of microgrid controllers will include machine learning algorithms. By analyzing historical load profiles and weather forecasts, these controllers optimize battery charging cycles and minimize grid import costs automatically.
Expanding Modular Designs: Future models in our 150kW to 500kW range will focus on hot-swappable power blocks. This design simplifies servicing and makes it easy to scale up power capacity over time.
Optimize your off-grid and microgrid configurations with our high-power wind-solar controllers, marine power units, and heavy-duty hybrid string inverters.
