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.

Application
A dc-coupled battery storage system—built around high-performance energy storage system lithium ion battery modules—mitigates the rapid power swings from photovoltaic and wind farms. By absorbing surplus generation during peaks and dispatching stored energy during troughs, the Solar and Battery Storage System smooths output profiles, minimizes resource waste, and sharply reduces solar and wind curtailment—offering best-in-class energy storage solutions for business.
These integrated ESS platforms execute precise load leveling—shaving demand peaks and filling valleys—to optimize grid dispatchability and alleviate infrastructure stress. With sub-second response times for grid frequency regulation, they bolster both utility-scale networks and islanded microgrids, ensuring voltage stability for mission-critical loads and delivering turnkey energy storage solutions for business continuity.
Leveraging off-peak charging, operators capitalize on tariff differentials to reduce electricity costs. In backup mode, the Solar and Battery Storage System seamlessly transitions to stored energy, curbing peak utility demand charges and guaranteeing uninterrupted power for essential services—an indispensable facet of modern energy storage solutions for business.
