太(tai)(tai)陽能(neng)(neng)并(bing)網(wang)逆(ni)變器(qi)是(shi)(shi)將電(dian)(dian)能(neng)(neng)反饋(kui)到電(dian)(dian)網(wang)，若電(dian)(dian)網(wang)斷(duan)電(dian)(dian)時，需快速的(de)(de)(de)(de)切斷(duan)供電(dian)(dian)給電(dian)(dian)網(wang)的(de)(de)(de)(de)線路，這是(shi)(shi)美國(guo)國(guo)家電(dian)(dian)氣(qi)規范（NEC）的(de)(de)(de)(de)要求(qiu)，以確保在斷(duan)電(dian)(dian)時，并(bing)網(wang)逆(ni)變器(qi)也會關閉，避免傷害維修電(dian)(dian)網(wang)的(de)(de)(de)(de)人員(yuan)。并(bing)網(wang)逆(ni)變器(qi)（Grid-tie inverters）：逆(ni)變器(qi)的(de)(de)(de)(de)輸出電(dian)(dian)壓(ya)(ya)可以回送到商用交流(liu)電(dian)(dian)源，因此輸出弦(xian)波需要和(he)電(dian)(dian)源的(de)(de)(de)(de)相位、頻率及(ji)電(dian)(dian)壓(ya)(ya)相同。太(tai)(tai)陽能(neng)(neng)逆(ni)變器(qi)是(shi)(shi)光(guang)伏電(dian)(dian)站的(de)(de)(de)(de)發電(dian)(dian)組件(jian)，家用光(guang)伏逆(ni)變器(qi)，其地位。這也決定了只要存在太(tai)(tai)陽能(neng)(neng)市(shi)場，太(tai)(tai)陽能(neng)(neng)逆(ni)變器(qi)市(shi)場就不(bu)會消(xiao)亡。

目前市(shi)面上的(de)(de)(de)并網(wang)逆變(bian)(bian)器(qi)有(you)使用(yong)許多不同(tong)的(de)(de)(de)技術，包括使用(yong)較新的(de)(de)(de)高頻變(bian)(bian)壓(ya)(ya)器(qi)、傳統的(de)(de)(de)工頻變(bian)(bian)壓(ya)(ya)器(qi)，光伏(fu)發(fa)電逆變(bian)(bian)器(qi)生產(chan)(chan)廠家，或是無變(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)(de)架構。大功(gong)率點的(de)(de)(de)目的(de)(de)(de)就是在各環境下(xia)，針對太陽能模組(zu)的(de)(de)(de)輸(shu)出(chu)取(qu)様，產(chan)(chan)生一個(ge)（太陽能模組(zu)的(de)(de)(de)）負載電阻來獲得大的(de)(de)(de)功(gong)率。一般光伏(fu)逆變(bian)(bian)器(qi)產(chan)(chan)品都給出(chu)了當直(zhi)流輸(shu)入電壓(ya)(ya)在允許波動(dong)(dong)范圍(wei)變(bian)(bian)動(dong)(dong)時，該光伏(fu)逆變(bian)(bian)器(qi)輸(shu)出(chu)電壓(ya)(ya)的(de)(de)(de)波動(dong)(dong)偏差的(de)(de)(de)百分率，通常稱為電壓(ya)(ya)調整率。
