What happened to Huawei inverters in 2022?
Huawei accounted for 29% of the inverters that were sold in the world in 2022. While it left the U.S. market in 2019, its equipment is used in many places. European utilities are also reconsidering dependence on Chinese parts because of fears of mass outages that could be initiated remotely.
Is Huawei still a global inverter company?
Huawei alone accounted for 29% of global shipments in 2022. While it exited the U.S. inverter market in 2019, it continues to supply other countries at scale. Philipp Schroeder, CEO of German solar developer 1Komma5, said his firm avoids Huawei products due to security risks.
What are the types of batteries for energy storage power stations
