Tsun raises €19m for 5x microinverter production boost
Tsun in China has raised RMB150m (€19m) in its second round of funding this year to increase production of its photovoltaic microinverters by 500%.
The Series B funding for Tsun was led by IDG Capital and follows an investment from Hidden Hill Capital in February and will be used to expand the automated production lines, production capacity, and technological advancements in core products. The funds will also support supply chain development and the expansion of domestic and international business channels.
Tsun is starting construction of its own factory this year with automated production lines, resulting in a 500% increase in production capacity when it opens in 2025. The 50,000 square meters facility is supported by Suzhou High-Speed Rail New City and will also house product development teams for a new generation of microinverter in 2024 for industrial and commercial applications.
Founded in 2019, Tsun develops microinverters and energy storage products. It introduced its TITAN series in 2020 as the world’s first high-power single-phase microinverter, alongside the Gen3 and Gen3 Plus series, covering power ranges from 300W to 3000W. In October 2023, the Gen3 was certified by VDE in Germany to the EN62920 EMC standard in October 2023, the first microinverter brand to receive the certification.
The company has also developed a plug-and-play balcony solar system designed for various installation scenarios including flat ground, railings and wall mounting, and is expanding its distribution channels in rapidly growing markets such as Europe, South America, and the Asia-Pacific region.
Cora Su, responsible for TSUN’s financing, emphasized the company’s commitment to a long-term strategy. Leveraging its strengths in technology research and development, integrated innovation, and industry resources, TSUN plans to enrich its product line, accelerate iteration, establish competitive advantages, and upgrade its intelligent core, contributing to the green transformation of low-carbon energy.
