China's Solar Giant Sungrow Refiles Hong Kong IPO Application

China's solar giant Sungrow Power Supply has filed a fresh application to list in Hong Kong, reviving plans initiated last year, as a wave of mainland companies seeks offshore funding to support overseas expansion.

The Shenzhen-listed solar inverter and energy storage system maker submitted its latest application proof to the Hong Kong stock exchange after an earlier filing in October lapsed, according to exchange disclosures late on Friday.

Sungrow, one of the world's largest suppliers of photovoltaic (PV) inverters, is positioning the Hong Kong listing as a platform to accelerate its globalisation strategy and broaden financing channels. Proceeds were expected to be used mainly for research and development as well as the construction of overseas production bases, according to market filings and company disclosures.

The refiled application came as a cluster of mainland companies – including Makesense Energy Technology, Befar Group and five others – submitted listing documents to Hong Kong on Friday, signalling a pickup in the city's initial public offering (IPO) pipeline.

Founded in 1997, Sungrow was listed on the Shenzhen bourse in 2011 and has grown into a global clean energy technology provider with operations spanning solar, wind, energy storage, electric vehicles and hydrogen. Its core products include PV inverters and energy storage systems, both of which rank among the global leaders by shipment volume.

The company's PV inverter shipments had held the top global position for a decade, with a market share of more than 25 per cent in 2024, while its cumulative energy storage system shipments exceeded 93 gigawatt-hours as of end-2025, according to the filing.
