太陽能(neng)(neng)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)可(ke)(ke)以分為以下(xia)幾類：獨立(li)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)（Stand-aloneinverters）：用在獨立(li)系統，光(guang)(guang)(guang)伏(fu)并(bing)網(wang)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)，光(guang)(guang)(guang)伏(fu)陣列為電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)，佛(fo)山逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)，逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)以電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)直流(liu)(liu)電(dian)(dian)(dian)(dian)壓為能(neng)(neng)量(liang)來(lai)源(yuan)(yuan)(yuan)。許(xu)多獨立(li)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)也整合了電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)(qi)，可(ke)(ke)以用交流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)為電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)。一般這種(zhong)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)不會(hui)接(jie)(jie)觸到電(dian)(dian)(dian)(dian)網(wang)，因此也不需(xu)要(yao)孤島效應保護機(ji)(ji)能(neng)(neng)。并(bing)網(wang)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)（Grid-tieinverters）：逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓可(ke)(ke)以回送到商用交流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，太陽能(neng)(neng)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)，因此輸(shu)出(chu)(chu)弦波需(xu)要(yao)和電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)相位(wei)、頻(pin)率及電(dian)(dian)(dian)(dian)壓相同(tong)。并(bing)網(wang)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)會(hui)有安全設計，若(ruo)未連接(jie)(jie)到電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，會(hui)自動關閉(bi)輸(shu)出(chu)(chu)。若(ruo)電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)跳電(dian)(dian)(dian)(dian)，光(guang)(guang)(guang)伏(fu)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)生(sheng)產廠家(jia)，并(bing)網(wang)逆(ni)變(bian)(bian)(bian)器(qi)(qi)(qi)(qi)(qi)(qi)沒有備存供電(dian)(dian)(dian)(dian)的(de)機(ji)(ji)能(neng)(neng)。

并(bing)(bing)網逆變(bian)(bian)器(qi)以(yi)(yi)往對于無變(bian)(bian)壓器(qi)，又要(yao)供電(dian)(dian)(dian)(dian)(dian)到(dao)電(dian)(dian)(dian)(dian)(dian)網的(de)(de)系統會(hui)有一些疑(yi)慮，主要(yao)是因(yin)為在直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)路和交(jiao)(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)路之間(jian)(jian)沒有電(dian)(dian)(dian)(dian)(dian)隔離（galvanicisolation），若直(zhi)流(liu)(liu)端(duan)故障，會(hui)有大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)流(liu)(liu)到(dao)交(jiao)(jiao)流(liu)(liu)端(duan)。不過自2005年起，美(mei)國消防協會(hui)（NFPA）的(de)(de)國家(jia)電(dian)(dian)(dian)(dian)(dian)氣規范允許無變(bian)(bian)壓器(qi)的(de)(de)逆變(bian)(bian)器(qi)。VDE0126-1-1及(ji)IEC6210也(ye)已(yi)允許及(ji)定義這類系統需要(yao)的(de)(de)安全機制。首先，需要(yao)有殘留電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)或(huo)是接(jie)地電(dian)(dian)(dian)(dian)(dian)路以(yi)(yi)檢測異常(chang)短路的(de)(de)情形，并(bing)(bing)且也(ye)要(yao)進(jin)行絕緣測試以(yi)(yi)確認直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)路與交(jiao)(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)路之間(jian)(jian)的(de)(de)分(fen)離。

逆變(bian)器的(de)主要用(yong)(yong)途在哪里？。逆變(bian)器是把直(zhi)流(liu)(liu)電(dian)能（電(dian)池、蓄電(dian)瓶）轉變(bian)成(cheng)交(jiao)流(liu)(liu)電(dian)（一般為220v50HZ正弦或(huo)方(fang)波）。通俗的(de)講，逆變(bian)器是一種將(jiang)直(zhi)流(liu)(liu)電(dian)（DC）轉化為交(jiao)流(liu)(liu)電(dian)（AC）的(de)裝(zhuang)置。它由逆變(bian)橋(qiao)、控制邏輯和濾波電(dian)路組成(cheng)。廣泛適用(yong)(yong)于空調、家庭影院、電(dian)動砂輪(lun)、電(dian)動工具、縫紉(ren)機、DVD、VCD、電(dian)腦(nao)、電(dian)視(shi)、洗衣機、抽油(you)煙機、冰箱，錄(lu)像機、器、風扇、照(zhao)明等。
