3KW/5KWH并離網(wǎng)儲能一體機(jī)（NESS3048S）
Hybrid Energy Storage System
系統(tǒng)組成（System composition）
3KW/5KWH并離網(wǎng)儲能一體機(jī)主要包括輸出功率3KW的逆變器設(shè)備，容量5KWH的儲能電池及智能監(jiān)測控制系統(tǒng)。儲能一體機(jī)可以與光伏發(fā)電系統(tǒng)、城市電網(wǎng)聯(lián)網(wǎng)運行，保證為客戶不間斷提供電源。系統(tǒng)拓?fù)淙缦聢D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)
● 后備UPS模式：城市電網(wǎng)在為負(fù)載供電的同時也為電池充電進(jìn)行儲能，當(dāng)電網(wǎng)斷電時，儲能一體機(jī)作為后備電源為用戶供電。
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 .
● 自發(fā)自用模式：儲能一體機(jī)工作在并網(wǎng)狀態(tài)，光伏發(fā)電在為負(fù)載提供電能的同時多余的電能輸送到電網(wǎng)，不足部分由電網(wǎng)補(bǔ)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：儲能一體機(jī)還可以與發(fā)電機(jī)一起構(gòu)筑光伏油電混合系統(tǒng)。
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.
