雙向(xiang)(xiang)計(ji)量(liang)電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)就(jiu)是能(neng)夠計(ji)量(liang)用電(dian)(dian)(dian)(dian)(dian)和(he)發(fa)電(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)，功(gong)率和(he)電(dian)(dian)(dian)(dian)(dian)能(neng)都是有方向(xiang)(xiang)的，從用電(dian)(dian)(dian)(dian)(dian)的角(jiao)度看，耗電(dian)(dian)(dian)(dian)(dian)的算(suan)為正(zheng)功(gong)率或正(zheng)電(dian)(dian)(dian)(dian)(dian)能(neng)，發(fa)電(dian)(dian)(dian)(dian)(dian)的算(suan)為負功(gong)率或負電(dian)(dian)(dian)(dian)(dian)能(neng)，該電(dian)(dian)(dian)(dian)(dian)表(biao)可(ke)以通過(guo)顯示屏分別讀出正(zheng)向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)量(liang)和(he)反向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)量(liang)并將電(dian)(dian)(dian)(dian)(dian)量(liang)數據存儲(chu)起來。

安(an)裝雙(shuang)(shuang)向(xiang)電(dian)表(biao)的(de)原因是由于光伏(fu)(fu)發出的(de)電(dian)存在(zai)不能(neng)(neng)(neng)全部被用(yong)戶(hu)消耗的(de)情(qing)況，而余下的(de)電(dian)能(neng)(neng)(neng)則需要(yao)輸送給電(dian)網(wang)，電(dian)表(biao)需要(yao)計(ji)量(liang)(liang)一個數(shu)字，在(zai)光伏(fu)(fu)發電(dian)不能(neng)(neng)(neng)滿足用(yong)戶(hu)需求時，這(zhe)又需要(yao)計(ji)量(liang)(liang)另一個數(shu)字，普通單(dan)塊表(biao)不能(neng)(neng)(neng)達到這(zhe)一要(yao)求，所以需要(yao)使用(yong)具有雙(shuang)(shuang)向(xiang)電(dian)表(biao)計(ji)量(liang)(liang)功能(neng)(neng)(neng)的(de)智能(neng)(neng)(neng)電(dian)表(biao)。
