Sungrow Power Supply Co. is expanding its focus on residential battery energy storage systems (BESS) to drive future growth as rising costs and intensifying competition weigh on profitability. The Chinese clean energy equipment manufacturer is targeting growing household and small business demand for energy storage amid rising electricity prices and concerns over power supply reliability.
The company expects global residential energy storage installations to reach 320 GWh by 2030, alongside another 80 GWh of capacity for small commercial and industrial (C&I) customers. According to Simon Liu, President of Distribution Sales and Marketing at Sungrow, the market is forecast to grow at an average compound annual rate of 25% over the next four years.
The expansion comes as Sungrow faces increasing pressure on its financial performance. The company’s net income declined 68% in the third quarter, while competitors focused on residential and commercial energy storage have reported stronger earnings growth amid rising overseas demand.
Sungrow Launches Integrated Residential Energy Storage Solution
As part of its residential energy storage strategy, Sungrow is introducing its PowerHarbor product, a 30 kW integrated system combining an inverter, battery storage and energy management functions.
The system is designed to help households manage electricity consumption, reduce exposure to fluctuating power prices and maintain power availability during grid outages.
Chuya Xu, Product Director at Sungrow’s Planning Department, said the company’s residential solutions aim to provide energy services while reducing consumers’ concerns about electricity prices, grid fluctuations and power interruptions.
Sungrow Targets Global Residential Storage Markets
Sungrow has already launched PowerHarbor in Europe and Australia and is exploring expansion into additional international markets. The company plans to organise approximately 300 product launch events across 50 countries next year to support its residential energy storage rollout.
Asia-Pacific and Europe remain key markets for Sungrow, while Latin America, the Middle East and Africa are emerging as growth regions for residential and commercial energy storage.
The company’s shift towards household battery storage reflects the growing role of distributed energy solutions in the global energy transition, particularly as consumers seek greater energy independence and reliable electricity supply.
