Sungrow builds the hardware and software that turns sunlight and wind into grid power at massive scale. Founded in 1997 and headquartered in Hefei, China, the company manufactures PV inverters, energy storage systems, EV chargers, and floating solar arrays. Its iSolarCloud platform handles fleet monitoring and energy management across those deployments. With 740 GW of power electronic converters installed globally as of December 2024, Sungrow operates the world's largest inverter manufacturing footprint.
For security engineers, the threat surface here is industrial control systems talking to the internet. The attack model spans firmware integrity on edge-deployed inverters, API security on iSolarCloud, supply chain assurance across global manufacturing, and OT/IT network segmentation at utility-scale installations. The company's stated mission - "Clean Power for All" - implies a target set that includes residential rooftops and utility substations alike, each with different risk profiles and regulatory requirements.
The technical stack crosses embedded systems, cloud platforms, and energy-sector SCADA environments. Security roles likely touch firmware signing pipelines, vulnerability management across a fleet of millions of connected devices, and compliance with energy-sector standards. With over 10,000 employees worldwide and operations spanning solar, wind, storage, EV charging, and hydrogen, the company is dealing with the kind of converged OT/IT problem set that makes energy infrastructure one of the more consequential domains in cybersecurity.
