光(guang)(guang)伏(fu)(fu)逆變(bian)(bian)(bian)器配置(zhi)選(xuan)型有哪些(xie)？額(e)(e)(e)(e)定輸出(chu)功(gong)(gong)率(lv)(lv)額(e)(e)(e)(e)定輸出(chu)功(gong)(gong)率(lv)(lv)表示(shi)光(guang)(guang)伏(fu)(fu)逆變(bian)(bian)(bian)器向負(fu)載(zai)供電(dian)的(de)(de)能力。額(e)(e)(e)(e)定輸出(chu)功(gong)(gong)率(lv)(lv)高的(de)(de)光(guang)(guang)伏(fu)(fu)逆變(bian)(bian)(bian)器可以(yi)帶(dai)更多的(de)(de)用電(dian)負(fu)載(zai)。選(xuan)用光(guang)(guang)伏(fu)(fu)逆變(bian)(bian)(bian)器時(shi)應首先考慮具有足夠的(de)(de)額(e)(e)(e)(e)定功(gong)(gong)率(lv)(lv)，以(yi)滿足負(fu)荷(he)下設備對(dui)電(dian)功(gong)(gong)率(lv)(lv)的(de)(de)要求，以(yi)及系統的(de)(de)擴容及一些(xie)臨時(shi)負(fu)載(zai)的(de)(de)接入(ru)。當用電(dian)設備以(yi)純電(dian)阻(zu)性負(fu)載(zai)為生(sheng)或功(gong)(gong)率(lv)(lv)因(yin)數大于0。9時(shi)，一般選(xuan)取光(guang)(guang)伏(fu)(fu)逆變(bian)(bian)(bian)器的(de)(de)額(e)(e)(e)(e)定輸出(chu)功(gong)(gong)率(lv)(lv)比用電(dian)設備總功(gong)(gong)率(lv)(lv)大10%`15%。

太陽(yang)能(neng)(neng)并(bing)網(wang)(wang)(wang)逆變(bian)器(qi)是(shi)將電(dian)(dian)能(neng)(neng)反饋到電(dian)(dian)網(wang)(wang)(wang)，若電(dian)(dian)網(wang)(wang)(wang)斷電(dian)(dian)時，需快速的切斷供電(dian)(dian)給(gei)電(dian)(dian)網(wang)(wang)(wang)的線路，這(zhe)是(shi)美(mei)國國家電(dian)(dian)氣規范（NEC）的要求，以(yi)確保在(zai)斷電(dian)(dian)時，池州逆變(bian)器(qi)，并(bing)網(wang)(wang)(wang)逆變(bian)器(qi)也會關閉，避免傷害維修電(dian)(dian)網(wang)(wang)(wang)的人員(yuan)。目前市面(mian)上的并(bing)網(wang)(wang)(wang)逆變(bian)器(qi)有使(shi)用許多不(bu)同的技術，包括使(shi)用較新的高(gao)(gao)頻變(bian)壓(ya)器(qi)、傳統的工頻變(bian)壓(ya)器(qi)，或是(shi)無變(bian)壓(ya)器(qi)的架構(gou)。高(gao)(gao)頻變(bian)壓(ya)器(qi)不(bu)是(shi)直接提供120V或240V的AC電(dian)(dian)源(yuan)，而是(shi)有電(dian)(dian)腦控(kong)制(zhi)的多步程序，讓電(dian)(dian)源(yuan)轉換(huan)為(wei)(wei)高(gao)(gao)頻的交流電(dian)(dian)，再轉換(huan)為(wei)(wei)直流電(dian)(dian)，后(hou)再轉換(huan)為(wei)(wei)電(dian)(dian)源(yuan)需要的電(dian)(dian)壓(ya)及頻率。

光伏逆(ni)(ni)(ni)變器(qi)(qi)配置選(xuan)型(xing)有(you)哪些(xie)？整(zheng)(zheng)機(ji)(ji)效(xiao)(xiao)率(lv)整(zheng)(zheng)機(ji)(ji)效(xiao)(xiao)率(lv)表示光伏逆(ni)(ni)(ni)變器(qi)(qi)自身功率(lv)損耗的(de)(de)大小。容量較大的(de)(de)光伏逆(ni)(ni)(ni)變器(qi)(qi)還(huan)要(yao)給出滿負荷(he)(he)工作(zuo)和(he)低(di)負荷(he)(he)工作(zuo)下的(de)(de)效(xiao)(xiao)率(lv)值(zhi)。一(yi)般KW級以(yi)(yi)下的(de)(de)逆(ni)(ni)(ni)變器(qi)(qi)的(de)(de)效(xiao)(xiao)率(lv)應(ying)為(wei)80%~85%;10KW級的(de)(de)效(xiao)(xiao)率(lv)應(ying)為(wei)85%~90%;更大功率(lv)的(de)(de)效(xiao)(xiao)率(lv)必(bi)須在90%~95%以(yi)(yi)上。逆(ni)(ni)(ni)變器(qi)(qi)低(di)對光伏發電(dian)系統提高有(you)效(xiao)(xiao)發電(dian)量和(he)降低(di)發電(dian)成本有(you)重要(yao)影響，因此選(xuan)用光伏逆(ni)(ni)(ni)變器(qi)(qi)要(yao)盡(jin)量進行(xing)比較，選(xuan)擇整(zheng)(zheng)機(ji)(ji)一(yi)些(xie)的(de)(de)產品。
