As renewable energy becomes a core pillar of the future, DASSTECH, a company based in Cheongju, South Korea, has proven itself as a key player in the green energy economy by driving technological innovation and providing exceptional customer service.

DASSTECH specializes in manufacturing solar inverters—essential devices that convert electricity generated by solar panels into usable power for daily life. In 2007, the company revolutionized the domestic market by introducing South Korea’s first transformerless inverter, which offered a more compact size and greater stability.

Innovation hasn’t stopped there. The company has since developed its technology through seven generations of inverter models, maintaining a strong focus on research and development.

“We were the ones who ushered in the transformerless inverter era in South Korea,”
– Jung Kwang-young, President of DASSTECH

DASSTECH was the first in the industry to implement real-time monitoring of system errors, malfunctions, and operational data. It also directly operates four service centers nationwide, reinforcing its customer care strategy.

In 2019, just over a decade after its founding, the company surpassed KRW 100 billion in sales, becoming South Korea’s largest solar inverter manufacturer.

“We used to focus mainly on the Southeast Asian market, but we’re now handling a major project in Peru,”
– Keum Man-hee, CEO of DASSTECH

The company is also expanding into electric vehicles and energy storage systems (ESS), signaling a new chapter of growth.

With a strong foundation in technology and customer service, DASSTECH is poised to become a global leader in clean energy solutions.
