Explore our core engineering items designed for advanced energy conversion, high-power regulation, and decentralized power grids.
Established in 2004, Jinan Deming Power Equipment Co., Ltd. has developed into a nationally recognized high-tech enterprise, specializing in the research, development, manufacturing, and global service of advanced renewable energy power equipment. Our focus lies at the crucial intersection of clean energy production and reliable electrical distribution—providing the industrial and utility sectors with robust solar/wind controllers, bidirectional inverters, battery simulators, and custom microgrid solutions.
With an unwavering commitment to engineering excellence, Deming operates under strict ISO9001:2015 quality management parameters and has been repeatedly designated a national High-Tech Enterprise by the Chinese government (2015, 2018). Our technical edge is sustained by a dedicated R&D team of 16 senior engineers, including highly qualified doctoral supervisors and master’s degree holders. To ensure we remain at the forefront of power electronics, we reinvest no less than 20% of our annual sales revenue back into core technology research. In the last three years alone, Deming successfully executed 17 R&D projects, seamlessly transforming 16 scientific and technological breakthroughs directly into commercially viable products.
Today, our highly specialized hardware and software configurations are deployed in over 120 countries, including highly regulated energy markets such as Germany, Japan, the United States, the UK, Canada, Australia, and Brazil. Our engineering capacity and reliable product lifecycles have earned us trusted partnerships with several Fortune 500 enterprises, solidifying our role as a major exporter of energy storage and grid-tied systems.
The global transition from centralized fossil-based power plants to distributed wind and solar arrays has created a critical engineering challenge: grid instability. Due to the variable and stochastic nature of wind speed, wind turbines present significant challenges in power quality, transient frequency shifts, and voltage drops. In modern Commercial and Industrial (C&I) environments, companies require clean, highly stable AC power that matches strict grid-code requirements.
China has emerged as the global leader in both wind turbine manufacturing and advanced power control electronics. As modern turbines grow from kW-scale localized assemblies to massive multi-megawatt systems, the demand for sophisticated controllers (like Deming's FKJ-GT on-grid controllers) has risen. Developers and system integrators must prioritize system balance: matching high-capacity permanent magnet generators with high-precision grid-tie controllers, bidirectional AC-DC converters, and battery energy storage systems (BESS) to buffer power during peak production and discharge during lull periods.
At a macro level, successful decarbonization requires hybridizing multiple energy inputs. Deming offers unified solutions that coordinate wind turbines, photovoltaic arrays, hydro generators, and BESS into cohesive microgrids. By combining high-capacity MPPT solar charge controllers with low-RPM permanent magnet generators, C&I facility operators can optimize their power output regardless of season or weather conditions.
Monitored storage systems store excess wind energy at night and discharge during expensive daytime peak hours, avoiding high demand tariffs.
Deploying ultra-fast bidirectional DC-DC and AC-DC converters to inject or absorb power within milliseconds of a frequency anomaly.
Managing grid-tie systems to ensure zero power feedback to the local utility where reverse-power flow is prohibited.
In high-capacity wind turbine integration, power conversion electronics must endure extreme electrical and thermal stress. The generator voltage fluctuates in direct proportion to wind velocity, demanding robust stabilization. The Deming FKJ-GT on-grid wind controller (available from 2kW to 100kW capacities) manages these challenges via several protection and optimization vectors:
Furthermore, for industrial applications demanding absolute reliability, our 300KW 480V Three-Phase AC/DC Converters boast a 99% conversion efficiency, keeping thermal dissipation to a minimum and maximizing system lifespan inside remote enclosures.
Our ISO9001:2015 certified production processes utilize advanced automation and precise diagnostics. Every component—from copper busbar alignment to semiconductor soldering—undergoes comprehensive inspection protocols before leaves our factory floors. Below is a detailed view of our assembly line and laboratory testing equipment, which allows our 16-engineer R&D team to inspect and verify every electrical parameter.
Deming's technology solutions are customized to perform across diverse geological and climate zones:
At busy harbors, dockside diesel generators on large vessels cause heavy localized emissions. Our High Capacity Shore Power Systems (500kW to 5MW) convert the local high-voltage grid power to clean, stable, ship-compliant electricity (typically 60Hz for international vessels), allowing docked ships to turn off their main engines while powering onboard systems.
In locations like remote parts of South America or high-altitude fields in Central Asia, standard electronics face degradation from thin air and extreme thermal cycling. Our IP54/IP65 protected enclosures, equipped with forced-air cooling and thermal-regulated heat exchangers, keep 50kW to 150kW off-grid hybrid inverters running reliably without derating.
Deploying energy equipment internationally requires strict adherence to local compliance systems. Deming ensures all exported systems conform to international safety and network-operator guidelines:
The energy conversion landscape is moving toward higher power density and smarter diagnostics. Deming is currently investing in the following research domains to keep our systems at the leading edge:
