TSUN Raises Over RMB 150M in Series B Funding

TSUN, a Suzhou, China-based photovoltaic (PV) manufacturing company, raised over RMB 150M in Series B funding.

The round was led by IDG Capital.

The company intends to use the funds to enhance its capabilities in 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.

Founded in 2019, TSUN is dedicated to the research and development of microinverters and energy storage products, contributing to a low-carbon and eco-friendly lifestyle. Its microinverter product lineup includes the Gen3, Gen3 Plus, and TITAN series, covering power ranges from 300W to 3000W. The company has also pioneered “household” applications of microinverters, exemplified by the Easy Solar Kit—a plug-and-play balcony solar system designed for various installation scenarios including flat ground, railings and wall mounting.

Having established collaborations with tier-one companies, TSUN has expanded distribution channels in markets such as Europe, South America, and the Asia-Pacific region. The company’s subsidiaries and offices worldwide contribute to a comprehensive market operations system, sales service network, and after-sales service system.
