太(tai)(tai)陽能逆(ni)(ni)變(bian)(bian)器(qi)(qi)可(ke)以(yi)(yi)分為(wei)：備用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池逆(ni)(ni)變(bian)(bian)器(qi)(qi)（Batterybackupinverters）是一(yi)種特殊的(de)逆(ni)(ni)變(bian)(bian)器(qi)(qi)，由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池作(zuo)為(wei)其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，配合其(qi)中(zhong)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，若(ruo)有過(guo)多的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力，會(hui)回灌(guan)到(dao)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源端。逆(ni)(ni)變(bian)(bian)器(qi)(qi)作(zuo)為(wei)光伏發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統內(nei)部重要(yao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣設備，其(qi)設備本身所配備的(de)各類保(bao)(bao)(bao)護功(gong)能較(jiao)為(wei)完善，具體有直(zhi)流(liu)(liu)母線過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓保(bao)(bao)(bao)護、交(jiao)流(liu)(liu)過(guo)欠壓保(bao)(bao)(bao)護、交(jiao)流(liu)(liu)頻率保(bao)(bao)(bao)護、極性反接保(bao)(bao)(bao)護、短路保(bao)(bao)(bao)護、孤(gu)島(dao)效應(ying)保(bao)(bao)(bao)護、過(guo)溫(wen)保(bao)(bao)(bao)護、直(zhi)流(liu)(liu)過(guo)載保(bao)(bao)(bao)護等保(bao)(bao)(bao)護功(gong)能。太(tai)(tai)陽能泵(beng)變(bian)(bian)頻器(qi)(qi)一(yi)般會(hui)有數(shu)個(ge)接口(kou)，逆(ni)(ni)變(bian)(bian)器(qi)(qi)生(sheng)產廠家(jia)，可(ke)以(yi)(yi)允許太(tai)(tai)陽能模組陣列(lie)提供(gong)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，逆(ni)(ni)變(bian)(bian)器(qi)(qi)多少錢，會(hui)有一(yi)個(ge)接口(kou)輸出交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，光伏逆(ni)(ni)變(bian)(bian)器(qi)(qi)生(sheng)產廠家(jia)，也(ye)可(ke)能會(hui)有接水位感測器(qi)(qi)輸入的(de)接口(kou)。

逆變(bian)(bian)(bian)器的主要用(yong)途在哪里？。逆變(bian)(bian)(bian)器是把直(zhi)流(liu)電(dian)能（電(dian)池、蓄(xu)電(dian)瓶(ping)）轉(zhuan)變(bian)(bian)(bian)成交(jiao)流(liu)電(dian)（一般為(wei)(wei)220v50HZ正弦或方波(bo)）。通俗的講，逆變(bian)(bian)(bian)器是一種將直(zhi)流(liu)電(dian)（DC）轉(zhuan)化為(wei)(wei)交(jiao)流(liu)電(dian)（AC）的裝置(zhi)。它由逆變(bian)(bian)(bian)橋(qiao)、控制邏輯和(he)濾波(bo)電(dian)路組成。廣泛(fan)適(shi)用(yong)于空調、家庭影院、電(dian)動砂(sha)輪、電(dian)動工具、縫紉機(ji)(ji)、DVD、VCD、電(dian)腦、電(dian)視(shi)、洗衣機(ji)(ji)、抽油煙(yan)機(ji)(ji)、冰箱，錄像機(ji)(ji)、器、風扇、照明等。

許多(duo)獨立逆(ni)變(bian)(bian)器也(ye)整合了電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)器，可以用(yong)交流電(dian)(dian)(dian)源為電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)。一般這種逆(ni)變(bian)(bian)器不會接觸到電(dian)(dian)(dian)網，安徽逆(ni)變(bian)(bian)器，因此(ci)(ci)也(ye)不需要(yao)孤島(dao)效(xiao)應保(bao)護機能。逆(ni)變(bian)(bian)器低(di)對光伏發(fa)(fa)電(dian)(dian)(dian)系統提高有效(xiao)發(fa)(fa)電(dian)(dian)(dian)量和(he)降低(di)發(fa)(fa)電(dian)(dian)(dian)成(cheng)本有重要(yao)影響(xiang)，因此(ci)(ci)選用(yong)光伏逆(ni)變(bian)(bian)器要(yao)盡量進(jin)行比(bi)較(jiao)，選擇整機一些的產(chan)品。太陽(yang)能逆(ni)變(bian)(bian)器在電(dian)(dian)(dian)網電(dian)(dian)(dian)源跳電(dian)(dian)(dian)時，可以提供(gong)交流電(dian)(dian)(dian)源給的負(fu)載，因此(ci)(ci)需要(yao)有孤島(dao)效(xiao)應保(bao)護機能。
