This Meg Solid solid-liquid energy storage cabinet adopts an AI early warning system and a comprehensive three-dimensional fire protection system integrating detection, prevention, ventilation and fire suppression to build multiple safety barriers and achieve intrinsic safety. The system delivers efficient energy conversion with a maximum efficiency of 88%. It is plug-and-play and easy to install, and up to 10 units can operate in parallel. Reserved diverse ports for handling and installation enable efficient and flexible deployment. Equipped with advanced self-evolving algorithms, it keeps the system temperature difference within ±5°C, enabling stable operation in extreme environments such as severe cold and scenarios requiring high protection levels, and it is resistant to high temperatures, strong winds and sand and dust. In addition, it supports real-time monitoring via cloud-based Web and APP as well as AI algorithm optimization strategies, realizing short-range and remote wireless control, one-click upgrade and on-demand scheduling. It is applicable to a wide range of scenarios including industrial facilities, commercial premises, microgrids, data centers, peak regulation and peak-valley arbitrage.
