什么是光伏組串：
在光伏發(fā)電系統(tǒng)中，將若干個光伏組件串聯(lián)后，形成具有一定直流輸出的電路單元，簡稱組件串或組串。
組串電流檢測有幾個典型的特點：
1.檢測電流的路數(shù)一般較多，典型的有8路16路等（匯流箱），逆變器則根據(jù)其MPPT設(shè)計各有不同。
2.對其檢測電流的精度有一定要求，但不做計量或計算需求。更大的意義在于實時監(jiān)控組件發(fā)電的狀態(tài)。
組串電流檢測的應(yīng)用：
匯流箱
是指用戶可以將一定數(shù)量、規(guī)格相同的光伏電池串聯(lián)起來，組成一個個光伏串列，然后再將若干個光伏串列并聯(lián)接入光伏匯流箱，起到匯流和監(jiān)控的裝置。匯流箱是作為組串電流的典型應(yīng)用代表。
逆變器
隨著分布式電站及商用家庭光伏發(fā)電的興起。尤其是國內(nèi)，組串式電流傳感器作為檢測光伏面板的*道監(jiān)控，發(fā)揮著*的作用。
電流檢測原件的迭代升級
原理篇
因為需要對光伏面板發(fā)出的電流進(jìn)行實時監(jiān)控，其關(guān)注電流一般在7A~10A的直流電流（雙面組件的電流會更大些）。要檢測這個檔位的直流電方案有很多。有比如電阻，光耦霍爾等檢測方案。這里可以講講光伏匯流箱里電流檢測方案的跟新迭代。
電阻方案：
在低頻率小幅值電流測量中，表現(xiàn)出高的精度和較快的響應(yīng)速度。工業(yè)領(lǐng)域中，在不涉及到測量回路與被測電流之間電隔離的場合，分流器是將電流信號轉(zhuǎn)變?yōu)殡妷盒盘柕牡牡统杀痉桨浮?/span>
