合(he)肥光伏(fu)逆變器(qi)-合(he)肥烈陽(yang)l售后(hou)無憂(you)-光伏(fu)逆變器(qi)多少(shao)錢

很大功率(lv)點（MPPT）的(de)(de)技術來從太陽(yang)能(neng)板抽(chou)取大可能(neng)的(de)(de)功率(lv)。太陽(yang)能(neng)電(dian)(dian)(dian)(dian)池的(de)(de)太陽(yang)輻照度、溫度及(ji)總電(dian)(dian)(dian)(dian)阻之間有(you)復雜的(de)(de)關系(xi)(xi)，因此輸出效率(lv)會有(you)非(fei)線性的(de)(de)變(bian)化，稱(cheng)為電(dian)(dian)(dian)(dian)流-電(dian)(dian)(dian)(dian)壓曲線（I-V curve）。太陽(yang)能(neng)并網(wang)逆變(bian)器(qi)是將電(dian)(dian)(dian)(dian)能(neng)反(fan)饋到電(dian)(dian)(dian)(dian)網(wang)，若電(dian)(dian)(dian)(dian)網(wang)斷(duan)電(dian)(dian)(dian)(dian)時(shi)，需快速的(de)(de)切斷(duan)供電(dian)(dian)(dian)(dian)給電(dian)(dian)(dian)(dian)網(wang)的(de)(de)線路，這(zhe)是美(mei)國(guo)國(guo)家電(dian)(dian)(dian)(dian)氣規范（NEC）的(de)(de)要求(qiu)，以(yi)確保在斷(duan)電(dian)(dian)(dian)(dian)時(shi)，并網(wang)逆變(bian)器(qi)也會關閉(bi)，避免傷害維修電(dian)(dian)(dian)(dian)網(wang)的(de)(de)人(ren)員。逆變(bian)器(qi)為光伏(fu)系(xi)(xi)統必不可少的(de)(de)一部(bu)分，又被叫做電(dian)(dian)(dian)(dian)源調整(zheng)器(qi)、功率(lv)調節器(qi)。

逆變(bian)器作為(wei)光伏發電(dian)(dian)(dian)系(xi)(xi)統內部重(zhong)要的(de)電(dian)(dian)(dian)氣設備，其設備本身所配備的(de)各(ge)類保(bao)(bao)護(hu)(hu)(hu)功能(neng)較為(wei)完(wan)善(shan)，具體有直流(liu)母線過(guo)(guo)電(dian)(dian)(dian)壓保(bao)(bao)護(hu)(hu)(hu)、交(jiao)流(liu)過(guo)(guo)欠(qian)壓保(bao)(bao)護(hu)(hu)(hu)、交(jiao)流(liu)頻率(lv)保(bao)(bao)護(hu)(hu)(hu)、極性反接保(bao)(bao)護(hu)(hu)(hu)、短(duan)路保(bao)(bao)護(hu)(hu)(hu)、孤島效應保(bao)(bao)護(hu)(hu)(hu)、過(guo)(guo)溫保(bao)(bao)護(hu)(hu)(hu)、直流(liu)過(guo)(guo)載保(bao)(bao)護(hu)(hu)(hu)等保(bao)(bao)護(hu)(hu)(hu)功能(neng)。許多獨(du)立逆變(bian)器也(ye)整合了(le)電(dian)(dian)(dian)池充電(dian)(dian)(dian)器，可以用交(jiao)流(liu)電(dian)(dian)(dian)源為(wei)電(dian)(dian)(dian)池充電(dian)(dian)(dian)。一(yi)般這種(zhong)逆變(bian)器不會接觸到電(dian)(dian)(dian)網，因(yin)此也(ye)不需要孤島效應保(bao)(bao)護(hu)(hu)(hu)機(ji)能(neng)。很大功率(lv)點（MPPT）的(de)技術(shu)來從太陽能(neng)板(ban)抽(chou)取大可能(neng)的(de)功率(lv)。太陽能(neng)電(dian)(dian)(dian)池的(de)太陽輻(fu)照(zhao)度(du)、溫度(du)及總電(dian)(dian)(dian)阻(zu)之間有復(fu)雜的(de)關系(xi)(xi)，因(yin)此輸出(chu)效率(lv)會有非線性的(de)變(bian)化，稱為(wei)電(dian)(dian)(dian)流(liu)-電(dian)(dian)(dian)壓曲線（I-V curve）。

太(tai)(tai)陽能逆變(bian)(bian)器既(ji)環保又(you)清潔(jie)，畢竟，這(zhe)是(shi)一(yi)(yi)種利用太(tai)(tai)陽能的(de)(de)產品，對(dui)環境的(de)(de)污染自然很(hen)小。以(yi)往對(dui)于無變(bian)(bian)壓器，又(you)要供電(dian)(dian)到電(dian)(dian)網的(de)(de)系統(tong)會有(you)一(yi)(yi)些疑(yi)慮，主要是(shi)因為在直(zhi)流(liu)電(dian)(dian)路(lu)和交流(liu)電(dian)(dian)路(lu)之間沒有(you)電(dian)(dian)隔(ge)離（galvanic isolation），若直(zhi)流(liu)端故障，會有(you)大電(dian)(dian)流(liu)流(liu)到交流(liu)端。微式(shi)光伏逆變(bian)(bian)器是(shi)只(zhi)配(pei)合單一(yi)(yi)太(tai)(tai)陽能模(mo)(mo)組(zu)運(yun)作的(de)(de)光伏逆變(bian)(bian)器，將太(tai)(tai)陽能模(mo)(mo)組(zu)的(de)(de)直(zhi)流(liu)電(dian)(dian)源轉換為交流(liu)電(dian)(dian)源。其設計允(yun)許以(yi)模(mo)(mo)組(zu)的(de)(de)方式(shi)由多臺微式(shi)光伏逆變(bian)(bian)器獨(du)立并聯(lian)運(yun)轉。
