一般(ban)光伏逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)產品都給出(chu)了當直(zhi)流(liu)輸入電(dian)壓(ya)在允(yun)許(xu)波動(dong)范圍變(bian)(bian)動(dong)時，該(gai)光伏逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)輸出(chu)電(dian)壓(ya)的波動(dong)偏差的百分率，通(tong)常稱(cheng)(cheng)為(wei)(wei)電(dian)壓(ya)調整(zheng)率。逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)低對光伏發(fa)電(dian)系統提(ti)高(gao)有效發(fa)電(dian)量和降低發(fa)電(dian)成本有重要影響，因(yin)此選用光伏逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)要盡(jin)量進行比較(jiao)，微型光伏逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)，選擇整(zheng)機一些的產品。物理上把(ba)將直(zhi)流(liu)電(dian)能(neng)(neng)變(bian)(bian)換成交流(liu)電(dian)能(neng)(neng)的過(guo)程(cheng)稱(cheng)(cheng)為(wei)(wei)逆(ni)(ni)(ni)(ni)變(bian)(bian)，把(ba)實(shi)現逆(ni)(ni)(ni)(ni)變(bian)(bian)過(guo)程(cheng)的裝置稱(cheng)(cheng)為(wei)(wei)逆(ni)(ni)(ni)(ni)變(bian)(bian)設備或逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)，逆(ni)(ni)(ni)(ni)變(bian)(bian)器(qi)(qi)的名稱(cheng)(cheng)由此而(er)來(lai)。

許多獨立逆變(bian)(bian)器(qi)也整合(he)了電(dian)(dian)池充電(dian)(dian)器(qi)，可以用交(jiao)流(liu)電(dian)(dian)源為電(dian)(dian)池充電(dian)(dian)。一般這(zhe)種逆變(bian)(bian)器(qi)不會接觸到電(dian)(dian)網，因此也不需要孤(gu)島效應保護機(ji)能。逆變(bian)(bian)器(qi)低對光伏(fu)發電(dian)(dian)系統提高有(you)效發電(dian)(dian)量和降低發電(dian)(dian)成本(ben)有(you)重要影響(xiang)，合(he)肥光伏(fu)逆變(bian)(bian)器(qi)，因此選用光伏(fu)逆變(bian)(bian)器(qi)要盡量進(jin)行比較，光伏(fu)逆變(bian)(bian)器(qi)回收，選擇整機(ji)一些(xie)的(de)產品。太(tai)陽能逆變(bian)(bian)器(qi)在(zai)電(dian)(dian)網電(dian)(dian)源跳(tiao)電(dian)(dian)時(shi)，可以提供交(jiao)流(liu)電(dian)(dian)源給的(de)負(fu)載，因此需要有(you)孤(gu)島效應保護機(ji)能。

許多(duo)獨立逆(ni)變(bian)(bian)(bian)器(qi)也整合了電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)器(qi)，光伏(fu)逆(ni)變(bian)(bian)(bian)器(qi)排名，可以(yi)用交流(liu)電(dian)(dian)(dian)源(yuan)為(wei)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)。一般這種逆(ni)變(bian)(bian)(bian)器(qi)不會接(jie)觸到電(dian)(dian)(dian)網(wang)，因此也不需要(yao)孤(gu)島效(xiao)應(ying)保護機(ji)能(neng)。并(bing)網(wang)逆(ni)變(bian)(bian)(bian)器(qi)會有(you)安全設(she)計(ji)，若未連接(jie)到電(dian)(dian)(dian)源(yuan)，會自動關閉輸出。若電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)源(yuan)跳電(dian)(dian)(dian)，并(bing)網(wang)逆(ni)變(bian)(bian)(bian)器(qi)沒有(you)備(bei)存供電(dian)(dian)(dian)的(de)(de)機(ji)能(neng)。物理上把(ba)(ba)將直流(liu)電(dian)(dian)(dian)能(neng)變(bian)(bian)(bian)換成交流(liu)電(dian)(dian)(dian)能(neng)的(de)(de)過程稱為(wei)逆(ni)變(bian)(bian)(bian)，把(ba)(ba)實現逆(ni)變(bian)(bian)(bian)過程的(de)(de)裝(zhuang)置稱為(wei)逆(ni)變(bian)(bian)(bian)設(she)備(bei)或逆(ni)變(bian)(bian)(bian)器(qi)，逆(ni)變(bian)(bian)(bian)器(qi)的(de)(de)名稱由(you)此而來。
