Industrial and commercial roof ESS

• 日用电负荷波动比较大的工商企业，如大型商场、写字楼、工厂、充电站等场所

• 具有峰谷电价差的场所，用电量大• 用电负荷增大，原有配电容量不足的场合• 具有不同负荷等级或消防应急供电场合

适用场景

• Large power consumption application such as in factories, shopping malls, office buildings, charging stations, sports centers, etc.

• peak-valley price application• large load fluctuation application• different load level and EPS application

Application

• 储能系统在用电尖峰时刻放电，削减负荷的变化率，达到平滑负荷的目的

• Energy storages during off-peak period and releases in peak hours. Commercial and industrial customers are able to save on their electricity bills by reducing peak demand, to realize "Peak Shaving" values

平滑负荷High Efficiency and High Profit

• 在原有配电网中接入储能系统，在用电低谷期存储电能，将储能的电在峰值电价期间使用，实现削峰填谷

方案Solution

• 当用户需增大用电负荷时，原有配电容量不足，增加储能系统，可达到扩容作用

• Load Leveling is used to smooth out the peaks and dips in energy demand—by reducing consumption at peak times increasing it during off-peak times ("valley filling"), or shifting the load from peak to off-peak periods—to maximize use of efficient baseload generation and reduce the need for spinning reserves

配电系统扩容Low Investment, East Installation

• 在市电停电时，储能系统离网运行，可选择性卸掉次要负荷，保障重要负荷供电可靠

• When the power outage occurs, the energy storage system runs in off-grid mode, and the secondary load can be selectively removed to guarantee the uninterrupted supply of critical loads
