微(wei)式(shi)光伏(fu)(fu)逆(ni)變器(qi)(qi)微(wei)式(shi)光伏(fu)(fu)逆(ni)變器(qi)(qi)是只配合單(dan)一(yi)太陽(yang)能(neng)模組(zu)(zu)運(yun)(yun)作的(de)光伏(fu)(fu)逆(ni)變器(qi)(qi)，光伏(fu)(fu)發(fa)電逆(ni)變器(qi)(qi)，將太陽(yang)能(neng)模組(zu)(zu)的(de)直流電源轉換(huan)為交流電源。其設計允許以(yi)模組(zu)(zu)的(de)方式(shi)由(you)多臺微(wei)式(shi)光伏(fu)(fu)逆(ni)變器(qi)(qi)獨立并聯運(yun)(yun)轉。微(wei)式(shi)光伏(fu)(fu)逆(ni)變器(qi)(qi)的(de)優點包括可(ke)以(yi)針對單(dan)一(yi)太陽(yang)能(neng)模組(zu)(zu)進行功率化，各個模組(zu)(zu)可(ke)以(yi)獨立運(yun)(yun)作，光伏(fu)(fu)電站(zhan)逆(ni)變器(qi)(qi)，即即用(yong)的(de)安裝方式(shi)，蕪湖(hu)逆(ni)變器(qi)(qi)，安裝方式(shi)及防火安全上的(de)提升(sheng)，系統設計的(de)成本(ben)，以(yi)及在庫存(cun)上也可(ke)以(yi)降到。

光(guang)伏逆(ni)變(bian)(bian)器的(de)(de)(de)功(gong)(gong)能(neng)(neng)有哪(na)些(xie)呢？大(da)功(gong)(gong)率(lv)跟(gen)蹤控(kong)制功(gong)(gong)能(neng)(neng)太(tai)(tai)陽(yang)(yang)電(dian)池組(zu)(zu)件(jian)的(de)(de)(de)輸(shu)出(chu)是(shi)隨太(tai)(tai)陽(yang)(yang)輻射強(qiang)(qiang)度(du)(du)和太(tai)(tai)陽(yang)(yang)電(dian)池組(zu)(zu)件(jian)自身溫(wen)度(du)(du)（芯(xin)片溫(wen)度(du)(du)）而變(bian)(bian)化(hua)的(de)(de)(de)。另外由于(yu)太(tai)(tai)陽(yang)(yang)電(dian)池組(zu)(zu)件(jian)具(ju)有電(dian)壓隨電(dian)流增大(da)而下降(jiang)的(de)(de)(de)特(te)性，因此(ci)存在能(neng)(neng)獲取(qu)功(gong)(gong)率(lv)的(de)(de)(de)工作點(dian)。太(tai)(tai)陽(yang)(yang)輻射強(qiang)(qiang)度(du)(du)是(shi)變(bian)(bian)化(hua)著(zhu)的(de)(de)(de)，顯然(ran)工作點(dian)也(ye)是(shi)在變(bian)(bian)化(hua)的(de)(de)(de)。相對于(yu)這(zhe)(zhe)些(xie)變(bian)(bian)化(hua)，始終讓(rang)太(tai)(tai)陽(yang)(yang)電(dian)池組(zu)(zu)件(jian)的(de)(de)(de)工作點(dian)處于(yu)功(gong)(gong)率(lv)點(dian)，陽(yang)(yang)光(guang)逆(ni)變(bian)(bian)器，系統(tong)始終從(cong)太(tai)(tai)陽(yang)(yang)電(dian)池組(zu)(zu)件(jian)獲取(qu)功(gong)(gong)率(lv)輸(shu)出(chu)，這(zhe)(zhe)種(zhong)控(kong)制就是(shi)功(gong)(gong)率(lv)跟(gen)蹤控(kong)制。太(tai)(tai)陽(yang)(yang)能(neng)(neng)發電(dian)系統(tong)用的(de)(de)(de)逆(ni)變(bian)(bian)器的(de)(de)(de)特(te)點(dian)就是(shi)包(bao)括了(le)功(gong)(gong)率(lv)點(dian)跟(gen)蹤（MPPT）這(zhe)(zhe)一功(gong)(gong)能(neng)(neng)。

微式(shi)光伏逆(ni)變(bian)(bian)器(qi)(qi)是只配合單(dan)一太陽(yang)能模(mo)(mo)組運作的光伏逆(ni)變(bian)(bian)器(qi)(qi)，將太陽(yang)能模(mo)(mo)組的直流(liu)(liu)電(dian)(dian)(dian)源(yuan)轉(zhuan)換為(wei)交流(liu)(liu)電(dian)(dian)(dian)源(yuan)。其設計允許(xu)以(yi)模(mo)(mo)組的方式(shi)由(you)多臺微式(shi)光伏逆(ni)變(bian)(bian)器(qi)(qi)獨(du)立(li)并聯運轉(zhuan)。光伏逆(ni)變(bian)(bian)器(qi)(qi)應同時給出當負載由(you)零向100%變(bian)(bian)化時，該光伏逆(ni)變(bian)(bian)器(qi)(qi)輸出電(dian)(dian)(dian)壓的偏(pian)差(cha)百(bai)分率，通常稱為(wei)負載調(diao)整率。許(xu)多獨(du)立(li)逆(ni)變(bian)(bian)器(qi)(qi)也(ye)整合了電(dian)(dian)(dian)池充電(dian)(dian)(dian)器(qi)(qi)，可以(yi)用交流(liu)(liu)電(dian)(dian)(dian)源(yuan)為(wei)電(dian)(dian)(dian)池充電(dian)(dian)(dian)。一般這種逆(ni)變(bian)(bian)器(qi)(qi)不會接觸(chu)到電(dian)(dian)(dian)網(wang)，因此也(ye)不需(xu)要孤(gu)島效(xiao)應保護機能。
