Product Description
Solar and Battery Storage System or solar system energy storage is a system that can store electric energy and supply power, with smooth transition, peak shaving and valley filling, frequency and voltage regulation and other functions. It can smooth the output of solar and wind power generation, and reduce the impact of its randomness, gap and fluctuation on the power grid and users; Charging in the valley price period and discharging in the peak price period can reduce the user's electricity expense; In case of power failure in the large power grid, it can operate independently to ensure uninterrupted power supply to users.
