系統配置蓄電池時，組成光伏儲能微網系統；不配置蓄電池時，可組成光伏微網系統，并在光伏和市電狀態下自動開機及運行。
無論在何種工作模式下(xia)，逆變器(qi)始(shi)終優先使用(yong)光(guang)伏(fu)能源(yuan)，光(guang)伏(fu)能量不夠時再由市(shi)電(dian)(dian)(dian)(dian)或蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)補充，光(guang)伏(fu)能量富余時，由蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)儲存；實現光(guang)伏(fu)發電(dian)(dian)(dian)(dian)化利(li)用(yong)，以達到節省電(dian)(dian)(dian)(dian)費的目的。
