Locations of Delta Inverter Manufacturing Facilities: A Complete Overview

1. Overview of Delta Electronics and Its Inverter Manufacturing Network

Founded in 1971 by Mr. Cheng Chonghua, Delta Electronics has grown from a key component manufacturer into a global provider of power management, thermal management, and energy-saving solutions. Headquartered in Taipei, Taiwan, China, the company entered the Chinese mainland market in 1992, establishing its first factory in Dongguan, Guangdong, and setting up Delta Greentech (China) Co., Ltd. in Shanghai to manage marketing and service network construction. Today, Delta operates across four core business segments: power and components, transportation, automation, and infrastructure, with inverters serving as a critical product line within its industrial automation portfolio.

As of 2026, Delta maintains a comprehensive manufacturing network for inverters and other industrial products across the Chinese mainland. The company currently operates four major established production bases in Dongguan (Guangdong), Wujiang (Jiangsu), Wuhu (Anhui), and Chenzhou (Hunan), with a fifth western manufacturing base under construction in Chongqing. This geographically distributed network allows Delta to efficiently serve domestic and global markets, leveraging local supply chain advantages and skilled labor pools to maintain product quality and delivery timelines. With over 40,000 employees, 25 R&D centers, and 45 operational outlets across the Chinese mainland, Delta's inverter manufacturing ecosystem integrates research, development, production, sales, and after-sales service to meet diverse customer demands.

Delta has long prioritized sustainable development, aligning its manufacturing strategy with its corporate mission of "Environmental Protection, Energy Conservation, and Love for the Earth." The company has joined the RE100 initiative, setting a target to achieve 100% renewable energy use and carbon neutrality across all its operations by 2030. This commitment extends to every inverter manufacturing facility, where energy-efficient production processes, green building standards, and circular economy practices are implemented to minimize environmental impact. Such efforts have earned Delta numerous recognitions, including being named a "Leading Enterprise in China's Industrial Carbon Peaking" in 2024 and maintaining 14 consecutive years of inclusion in the Dow Jones Best-in-Class World Index.
