As the core component of the energy storage system that realizes bidirectional energy conversion and adapts to the power grid, PCS plays a very important role.
 
 
 
PCS can smoothly switch between grid-connected and off-grid, control the charging and discharging process, improve the quality of output power, and ensure the safe operation and service life of the energy storage battery pack.
 
 
 
Relevant organizations predict that the global installed capacity of energy storage will grow by 56% in the next five years, and will reach about 270GW by 2026, and the global energy storage market size will be more than 100 billion U.S. dollars.
 
 
 
The United States, as a large country with energy storage demand, has a huge PCS market and attaches great importance to the research and development of PCS technology.
 
 
 
In 2023, the U.S. annual energy storage installation is expected to reach 8.36GW, a year-on-year growth of 103%; in 2024, the U.S. plans to install 14.91GW of energy storage, a year-on-year growth of 78.4%.
 
 
 
PCS technology innovation will promote the performance of the entire energy storage system to improve, will more reduce the unit cost and loss of the U.S. energy storage installation, to expand more application scenarios.
 
 
 
Tide Power Intelligence summarizes the top 5 U.S. local self-developed PCS vendors here.
