Whether it is peak shaving and valley filling, self-generation and self-use, dynamic capacity expansion, or planned curve response, it can be achieved with one click, meeting users' diversified energy management strategies. The linkage of local and cloud monitoring has elevated digital management to a new level. Users can view the operating status of the system and perform remote control and parameter adjustment anytime and anywhere through mobile phones or computers. The digital rapid diagnosis and intelligent automatic inspection functions can timely detect and deal with potential fault hazards, ensuring the long-term stable operation of the system and greatly reducing maintenance costs and workload.

## Grid-Friendly, Assisting Stable Grid Operation

In terms of grid connection, the GSO Air-Cooled Outdoor Cabinet—Hybrid Grid-Tied/Off-Grid Machine shows extremely high friendliness. It is equipped with active and reactive power four-quadrant regulation functions, which can flexibly adjust output power and power factor according to the needs of the power grid, effectively improve the power quality of the power grid, and enhance the operating efficiency and stability of the power grid. The LVRT and HVRT functions enable the equipment to maintain stable operation when the grid voltage fluctuates, providing strong support for the safe and stable operation of the power grid. In addition, the precise switching function of source, grid, and load realizes the precise matching of energy supply and load demand, further optimizing the energy utilization efficiency and reducing dependence on the power grid, providing a solid technical foundation for building distributed energy systems and microgrids.

## Widely Applied, Meeting Diversified Energy Storage Needs

The GSO Air-Cooled Outdoor Cabinet—Hybrid Grid-Tied/Off-Grid Machine has two models, GSO50-100V and GSO100-200V, with rated powers of 50kW and 100kW respectively, which can meet the needs of users of different scales. For small C&I users, the GSO50-100V model can effectively cope with the daily power demand fluctuations. Through peak shaving and valley filling and self-generation and self-use, it reduces electricity costs and improves energy utilization efficiency. In hospitals and other places with extremely high requirements for power supply stability, the high-power output and seamless switching capability of the GSO100-200V model can ensure the continuous operation of key equipment and ensure medical safety. For residential users, both models can provide reliable power backup. In the event of a power grid failure, they can provide a stable power supply for family life. At the same time, through PV access and intelligent management, they can achieve energy self-sufficiency, reduce electricity expenditure, and improve the quality of life.
