高(gao)頻變壓器(qi)不(bu)是(shi)(shi)直接(jie)提供120V或(huo)240V的(de)AC電(dian)(dian)(dian)(dian)源(yuan)，逆變器(qi)報價(jia)，而是(shi)(shi)有(you)電(dian)(dian)(dian)(dian)腦控制(zhi)的(de)多步程序，讓電(dian)(dian)(dian)(dian)源(yuan)轉(zhuan)換(huan)(huan)為(wei)高(gao)頻的(de)交流(liu)電(dian)(dian)(dian)(dian)，再轉(zhuan)換(huan)(huan)為(wei)直流(liu)電(dian)(dian)(dian)(dian)，后(hou)再轉(zhuan)換(huan)(huan)為(wei)電(dian)(dian)(dian)(dian)源(yuan)需要的(de)電(dian)(dian)(dian)(dian)壓及頻率(lv)(lv)(lv)。光伏(fu)逆變器(qi)不(bu)只具(ju)有(you)直交流(liu)變換(huan)(huan)功用，還具(ju)有(you)限制(zhi)地(di)發揚太陽電(dian)(dian)(dian)(dian)池功能的(de)功用和系統毛病維護(hu)功用。光伏(fu)逆變器(qi)應同時(shi)(shi)給出當負載由(you)零(ling)向100%變化時(shi)(shi)，該(gai)光伏(fu)逆變器(qi)輸出電(dian)(dian)(dian)(dian)壓的(de)偏差百分率(lv)(lv)(lv)，通常稱為(wei)負載調整(zheng)率(lv)(lv)(lv)。

微式(shi)光伏(fu)逆(ni)(ni)變(bian)(bian)器(qi)(qi)是只配合單一太陽能(neng)(neng)(neng)模(mo)(mo)組運作的(de)(de)光伏(fu)逆(ni)(ni)變(bian)(bian)器(qi)(qi)，將太陽能(neng)(neng)(neng)模(mo)(mo)組的(de)(de)直流(liu)電(dian)(dian)(dian)源(yuan)轉換為交流(liu)電(dian)(dian)(dian)源(yuan)。其(qi)設計允(yun)許以模(mo)(mo)組的(de)(de)方式(shi)由多臺微式(shi)光伏(fu)逆(ni)(ni)變(bian)(bian)器(qi)(qi)獨立(li)并聯運轉。并網逆(ni)(ni)變(bian)(bian)器(qi)(qi)（Grid-tieinverters）：逆(ni)(ni)變(bian)(bian)器(qi)(qi)的(de)(de)輸出電(dian)(dian)(dian)壓(ya)可以回送到(dao)商用交流(liu)電(dian)(dian)(dian)源(yuan)，馬(ma)鞍山逆(ni)(ni)變(bian)(bian)器(qi)(qi)，因此(ci)輸出弦波需要和電(dian)(dian)(dian)源(yuan)的(de)(de)相位(wei)、頻率(lv)及(ji)電(dian)(dian)(dian)壓(ya)相同。物理上(shang)把(ba)將直流(liu)電(dian)(dian)(dian)能(neng)(neng)(neng)變(bian)(bian)換成交流(liu)電(dian)(dian)(dian)能(neng)(neng)(neng)的(de)(de)過程(cheng)稱(cheng)為逆(ni)(ni)變(bian)(bian)，把(ba)實(shi)現(xian)逆(ni)(ni)變(bian)(bian)過程(cheng)的(de)(de)裝(zhuang)置稱(cheng)為逆(ni)(ni)變(bian)(bian)設備或逆(ni)(ni)變(bian)(bian)器(qi)(qi)，逆(ni)(ni)變(bian)(bian)器(qi)(qi)的(de)(de)名稱(cheng)由此(ci)而(er)來。

太(tai)陽能(neng)(neng)逆變器既環(huan)保又清潔，畢竟，這(zhe)是(shi)一(yi)種利用太(tai)陽能(neng)(neng)的(de)(de)(de)產品，對環(huan)境(jing)的(de)(de)(de)污染自然很小。一(yi)般光(guang)伏逆變器產品都給出(chu)了當直(zhi)流(liu)輸(shu)入(ru)電(dian)壓(ya)在允許波動(dong)范圍變動(dong)時，該光(guang)伏逆變器輸(shu)出(chu)電(dian)壓(ya)的(de)(de)(de)波動(dong)偏差的(de)(de)(de)百(bai)分率，通常(chang)稱為(wei)電(dian)壓(ya)調整率。太(tai)陽能(neng)(neng)泵變頻器可以將太(tai)陽能(neng)(neng)模組(zu)產生(sheng)的(de)(de)(de)直(zhi)流(liu)電(dian)轉換為(wei)交流(liu)電(dian)去驅動(dong)沈水泵，不(bu)需要(yao)電(dian)池或(huo)是(shi)其他的(de)(de)(de)能(neng)(neng)量(liang)儲存設備。
