太(tai)陽能并(bing)網(wang)(wang)(wang)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)是(shi)(shi)將電(dian)(dian)(dian)能反饋(kui)到(dao)電(dian)(dian)(dian)網(wang)(wang)(wang)，若(ruo)電(dian)(dian)(dian)網(wang)(wang)(wang)斷電(dian)(dian)(dian)時，需快速的(de)(de)切斷供電(dian)(dian)(dian)給(gei)電(dian)(dian)(dian)網(wang)(wang)(wang)的(de)(de)線路(lu)，逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)批發，這是(shi)(shi)美國(guo)(guo)國(guo)(guo)家電(dian)(dian)(dian)氣(qi)規范（NEC）的(de)(de)要(yao)求，以確保(bao)在斷電(dian)(dian)(dian)時，并(bing)網(wang)(wang)(wang)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)也會(hui)關閉，蚌埠逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)，避免傷害維(wei)修電(dian)(dian)(dian)網(wang)(wang)(wang)的(de)(de)人員。目前(qian)市面上的(de)(de)并(bing)網(wang)(wang)(wang)逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)有使用(yong)許多不(bu)同的(de)(de)技術，儲能逆(ni)(ni)變(bian)(bian)器(qi)(qi)(qi)報價，包括使用(yong)較新的(de)(de)高頻(pin)(pin)變(bian)(bian)壓器(qi)(qi)(qi)、傳(chuan)統的(de)(de)工頻(pin)(pin)變(bian)(bian)壓器(qi)(qi)(qi)，或是(shi)(shi)無變(bian)(bian)壓器(qi)(qi)(qi)的(de)(de)架構。高頻(pin)(pin)變(bian)(bian)壓器(qi)(qi)(qi)不(bu)是(shi)(shi)直(zhi)接提供120V或240V的(de)(de)AC電(dian)(dian)(dian)源，而是(shi)(shi)有電(dian)(dian)(dian)腦控(kong)制的(de)(de)多步程序，讓電(dian)(dian)(dian)源轉(zhuan)換(huan)為(wei)高頻(pin)(pin)的(de)(de)交流(liu)電(dian)(dian)(dian)，再轉(zhuan)換(huan)為(wei)直(zhi)流(liu)電(dian)(dian)(dian)，后再轉(zhuan)換(huan)為(wei)電(dian)(dian)(dian)源需要(yao)的(de)(de)電(dian)(dian)(dian)壓及頻(pin)(pin)率。

光伏逆(ni)(ni)變(bian)器(qi)(qi)的(de)(de)好處有哪些呢？太陽能逆(ni)(ni)變(bian)器(qi)(qi)中的(de)(de)太陽能系統主要由電(dian)池板(ban)，充電(dian)控制器(qi)(qi)，逆(ni)(ni)變(bian)器(qi)(qi)和電(dian)池組成(cheng)。大多(duo)數人都(dou)知道這一點。但是(shi)，逆(ni)(ni)變(bian)器(qi)(qi)可(ke)能會碰到更少的(de)(de)人，而逆(ni)(ni)變(bian)器(qi)(qi)實際(ji)上(shang)是(shi)一臺。可(ke)以將用(yong)于功率轉換的(de)(de)設備說成(cheng)是(shi)將電(dian)池中的(de)(de)直流電(dian)轉換成(cheng)交(jiao)流電(dian)的(de)(de)設備。可(ke)以根據勵(li)磁方式對逆(ni)(ni)變(bian)器(qi)(qi)進行分類，主要是(shi)自激式逆(ni)(ni)變(bian)器(qi)(qi)和其他(ta)勵(li)磁振蕩式逆(ni)(ni)變(bian)器(qi)(qi)。

光(guang)伏(fu)逆(ni)(ni)(ni)(ni)變器配置選型有(you)哪些？整(zheng)機效(xiao)率(lv)(lv)(lv)整(zheng)機效(xiao)率(lv)(lv)(lv)表示光(guang)伏(fu)逆(ni)(ni)(ni)(ni)變器自身功率(lv)(lv)(lv)損耗的(de)(de)大(da)小。容量較(jiao)大(da)的(de)(de)光(guang)伏(fu)逆(ni)(ni)(ni)(ni)變器還(huan)要(yao)給出(chu)滿負(fu)荷(he)工作和低負(fu)荷(he)工作下(xia)的(de)(de)效(xiao)率(lv)(lv)(lv)值。一(yi)般KW級以下(xia)的(de)(de)逆(ni)(ni)(ni)(ni)變器的(de)(de)效(xiao)率(lv)(lv)(lv)應為80%~85%;10KW級的(de)(de)效(xiao)率(lv)(lv)(lv)應為85%~90%;更大(da)功率(lv)(lv)(lv)的(de)(de)效(xiao)率(lv)(lv)(lv)必須(xu)在90%~95%以上。逆(ni)(ni)(ni)(ni)變器低對光(guang)伏(fu)發電(dian)系統提高有(you)效(xiao)發電(dian)量和降低發電(dian)成本有(you)重要(yao)影響，因此選用光(guang)伏(fu)逆(ni)(ni)(ni)(ni)變器要(yao)盡量進行比(bi)較(jiao)，選擇整(zheng)機一(yi)些的(de)(de)產品。
