3KW/5KWH并离网储能一体机（NESS3048S）
Hybrid Energy Storage System
系统组成（System composition）
3KW/5KWH并离网储能一体机主要包括输出功率3KW的逆变器设备，容量5KWH的储能电池及智能监测控制系统。储能一体机可以与光伏发电系统、城市电网联网运行，保证为客户不间断提供电源。系统拓扑如下图所示。
3KW/5KWH Hybrid Energy Storage System integrated machine mainly includes one inverter equipment whose output power is 3KW, one storage battery whose capacity is 5KWH and intelligent monitoring and control system. The energy storage integrated machine can be connected with the photovoltaic power generation system and the urban power grid to ensure uninterrupted supply of power for the customers. The system topology is shown below。
工作模式(Working mode)
● 后备UPS模式：城市电网在为负载供电的同时也为电池充电进行储能，当电网断电时，储能一体机作为后备电源为用户供电。
Backup UPS mode: City power grid not only supplies power to the load , but also charges storage battery. If the city power grid is disconnected, the energy storage machine will be a backup power .
● 自发自用模式：储能一体机工作在并网状态，光伏发电在为负载提供电能的同时多余的电能输送到电网，不足部分由电网补充。
Spontaneous use mode: When the energy storage integrated machine connects with the city power grid, on the one hand, photovoltaic power generation supplies power to the load. At the same time, excess power is transported to the city power grid, inadequate part of the grid supplement. On the other hand, when the photovoltaic power generation can not supply enough power, the city power will supplement.
● 混合模式：储能一体机还可以与发电机一起构筑光伏油电混合系统。
Hybrid mode: the energy storage integrated machine can also be used to construct photovoltaic oil and electricity hybrid system with the generator. It can be configured flexibly according to customer requirements.
