太陽能(neng)逆(ni)變(bian)器(qi)可以(yi)分為：備用電(dian)(dian)(dian)(dian)池(chi)逆(ni)變(bian)器(qi)（Batterybackupinverters）是一種特殊的(de)(de)(de)逆(ni)變(bian)器(qi)，光伏逆(ni)變(bian)器(qi)生產廠家，由電(dian)(dian)(dian)(dian)池(chi)作(zuo)為其(qi)電(dian)(dian)(dian)(dian)源，配合(he)其(qi)中的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)器(qi)為電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)，若有(you)(you)(you)過(guo)多的(de)(de)(de)電(dian)(dian)(dian)(dian)力，會(hui)回灌到交(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源端(duan)。逆(ni)變(bian)器(qi)作(zuo)為光伏發電(dian)(dian)(dian)(dian)系統(tong)內部重要(yao)的(de)(de)(de)電(dian)(dian)(dian)(dian)氣設備，其(qi)設備本身所配備的(de)(de)(de)各類保(bao)(bao)(bao)(bao)護(hu)(hu)功能(neng)較為完善，具體有(you)(you)(you)直(zhi)流(liu)(liu)(liu)母(mu)線過(guo)電(dian)(dian)(dian)(dian)壓保(bao)(bao)(bao)(bao)護(hu)(hu)、交(jiao)(jiao)流(liu)(liu)(liu)過(guo)欠壓保(bao)(bao)(bao)(bao)護(hu)(hu)、交(jiao)(jiao)流(liu)(liu)(liu)頻(pin)率(lv)保(bao)(bao)(bao)(bao)護(hu)(hu)、極性(xing)反接保(bao)(bao)(bao)(bao)護(hu)(hu)、短(duan)路保(bao)(bao)(bao)(bao)護(hu)(hu)、孤島效應保(bao)(bao)(bao)(bao)護(hu)(hu)、過(guo)溫(wen)保(bao)(bao)(bao)(bao)護(hu)(hu)、直(zhi)流(liu)(liu)(liu)過(guo)載(zai)保(bao)(bao)(bao)(bao)護(hu)(hu)等保(bao)(bao)(bao)(bao)護(hu)(hu)功能(neng)。太陽能(neng)泵變(bian)頻(pin)器(qi)一般會(hui)有(you)(you)(you)數個接口，可以(yi)允(yun)許(xu)太陽能(neng)模組(zu)陣列(lie)提供直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，安慶逆(ni)變(bian)器(qi)，會(hui)有(you)(you)(you)一個接口輸(shu)出(chu)交(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓，也可能(neng)會(hui)有(you)(you)(you)接水(shui)位感測器(qi)輸(shu)入(ru)的(de)(de)(de)接口。

逆(ni)變器(qi)就是一(yi)種(zhong)將(jiang)低壓(12或(huo)(huo)24伏(fu)或(huo)(huo)48伏(fu))直流(liu)(liu)電(dian)(dian)(dian)轉變為(wei)220伏(fu)交(jiao)流(liu)(liu)電(dian)(dian)(dian)的(de)電(dian)(dian)(dian)子設備。因(yin)為(wei)我(wo)們通(tong)常(chang)是將(jiang)220伏(fu)交(jiao)流(liu)(liu)電(dian)(dian)(dian)整流(liu)(liu)變成直流(liu)(liu)電(dian)(dian)(dian)來使(shi)用，而逆(ni)變器(qi)的(de)作用與此(ci)(ci)相反，因(yin)此(ci)(ci)而得(de)名。我(wo)們處在(zai)一(yi)個“移(yi)動”的(de)時代，移(yi)動辦公，移(yi)動通(tong)訊，移(yi)動休閑和娛(yu)樂。在(zai)移(yi)動的(de)狀態中，儲能逆(ni)變器(qi)，人們不但需要由電(dian)(dian)(dian)池或(huo)(huo)電(dian)(dian)(dian)瓶供(gong)給(gei)的(de)低壓直流(liu)(liu)電(dian)(dian)(dian)，同時更需要我(wo)們在(zai)日(ri)常(chang)環境中不可或(huo)(huo)缺(que)的(de)220伏(fu)交(jiao)流(liu)(liu)電(dian)(dian)(dian)，逆(ni)變器(qi)就可以滿足我(wo)們的(de)這種(zhong)需求。

太陽(yang)能(neng)逆(ni)變(bian)器可以(yi)(yi)(yi)分為以(yi)(yi)(yi)下幾類(lei)：獨(du)立逆(ni)變(bian)器（Stand-aloneinverters）：用在獨(du)立系統，光伏陣列為電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，逆(ni)變(bian)器以(yi)(yi)(yi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的直流(liu)電(dian)(dian)(dian)(dian)(dian)壓為能(neng)量來源(yuan)(yuan)。許多(duo)獨(du)立逆(ni)變(bian)器也(ye)(ye)整合(he)了電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)器，逆(ni)變(bian)器生產工廠(chang)，可以(yi)(yi)(yi)用交流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)為電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)。一般這種(zhong)逆(ni)變(bian)器不(bu)(bu)會接(jie)觸到電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)，因(yin)此也(ye)(ye)不(bu)(bu)需要孤島(dao)效應保護機(ji)能(neng)。并(bing)網(wang)(wang)(wang)逆(ni)變(bian)器（Grid-tieinverters）：逆(ni)變(bian)器的輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓可以(yi)(yi)(yi)回送(song)到商用交流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，因(yin)此輸(shu)出弦(xian)波需要和電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的相位、頻(pin)率(lv)及電(dian)(dian)(dian)(dian)(dian)壓相同。并(bing)網(wang)(wang)(wang)逆(ni)變(bian)器會有安(an)全設計，若未(wei)連接(jie)到電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，會自動關(guan)閉輸(shu)出。若電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)跳電(dian)(dian)(dian)(dian)(dian)，并(bing)網(wang)(wang)(wang)逆(ni)變(bian)器沒有備(bei)存供電(dian)(dian)(dian)(dian)(dian)的機(ji)能(neng)。
