Sungrow Accelerates 'Time-to-Grid' for Myanmar's Largest PV & BESS Project, Completing Commissioning in Seven Days

Mandalay, Myanmar — Sungrow, a leading global provider of photovoltaic (PV) inverters and energy storage systems, has announced that the integrated solar and energy storage project belonging to Hanzar Solar and Leader Power Energy in Myanmar has commenced commercial operations. With a capacity of 110 MW PV and 20 MW/40 MWh BESS, this is the largest photovoltaic power plant in Myanmar and is set to enhance power supply reliability while supporting national energy mix diversification.

Thanks to Sungrow’s integrated solar and energy storage solutions, the project reached commercial operation after a testing and commissioning process lasting only seven days, establishing a new standard for large-scale renewable energy implementation in Southeast Asia. Despite a very tight schedule, the project was completed through efficient coordination between Sungrow’s headquarters and local teams, alongside close collaboration in engineering, commissioning, and operations. Supported by Sungrow’s regional resources in Southeast Asia, the testing and commissioning process, originally scheduled for two weeks, was successfully completed in just two days without operational incidents.

Key factors in the accelerated timeline included the use of Sungrow’s 1+X Modular Inverter solution, which supports commissioning in off-grid mode, thereby reducing reliance on diesel generators and minimising on-site preparation. Furthermore, due to the vertically integrated architecture of the Energy Storage System (ESS), primary equipment underwent preliminary assembly and integrated commissioning before being dispatched to the site, reducing the workload in the field. Additionally, Sungrow’s experienced technical team provided 24-hour on-site support to ensure rapid response to technical needs.

Located in the Mandalay region, the project operates in an environment characterised by long dry seasons and temperatures exceeding 40 degrees Celsius. To address these challenges, the project utilises 1+X Modular Inverters, the PowerTitan 2.0 energy storage system, and an intelligent power generation management platform. The facility is equipped with grid-forming PCS technology and Black Start features, allowing for independent microgrid operation to supply local electricity needs and reactivate essential facilities when required. Although current grid conditions do not yet allow for full grid-forming technology utilisation, the system has demonstrated optimal operational flexibility in isolated mode and is prepared to support future grid modernisation and emergency supply needs.

“We greatly appreciate the professionalism, rapid response, and continuous support from Sungrow during the project execution,” said Tony Yang, Managing Director of Power Way International Limited. “Strong technical capability, efficient coordination, and reliable on-site services were critical factors in ensuring the commissioning process proceeded smoothly and was completed in such a short timeframe.”

This project demonstrates Sungrow’s ability to deliver local execution, rapid implementation, and integrated clean energy solutions to accelerate the energy transition in Southeast Asia.
