（1）運行原理：

    【離網發電(dian)(dian)(dian)】光(guang)伏(fu)組件在(zai)有光(guang)照的情況下將(jiang)太(tai)(tai)陽(yang)能(neng)轉換為(wei)電(dian)(dian)(dian)能(neng)，通(tong)過太(tai)(tai)陽(yang)能(neng)充放(fang)電(dian)(dian)(dian)控制器給負(fu)(fu)(fu)載供(gong)電(dian)(dian)(dian)，同(tong)時(shi)(shi)給蓄(xu)電(dian)(dian)(dian)池組充電(dian)(dian)(dian)；在(zai)無光(guang)照時(shi)(shi)，通(tong)過太(tai)(tai)陽(yang)能(neng)充放(fang)電(dian)(dian)(dian)控制器由蓄(xu)電(dian)(dian)(dian)池組給直流負(fu)(fu)(fu)載供(gong)電(dian)(dian)(dian)，同(tong)時(shi)(shi)蓄(xu)電(dian)(dian)(dian)池還要直接給獨(du)立逆變器供(gong)電(dian)(dian)(dian)，通(tong)過獨(du)立逆變器逆變成交(jiao)(jiao)流電(dian)(dian)(dian)，給交(jiao)(jiao)流負(fu)(fu)(fu)載供(gong)電(dian)(dian)(dian)。

（2）適用范圍：

離網型(xing)光伏(fu)發電系統廣(guang)泛應(ying)用于偏僻(pi)山區(qu)、無電區(qu)、海島、通(tong)訊基(ji)站和(he)路燈等應(ying)用場所。   ;

（3）系統特點：

太陽能隨處可見，可就(jiu)近供電，不必長(chang)距離輸送，避免了(le)長(chang)距離輸電線路(lu)的損失；

太陽能不用燃料，運(yun)行(xing)成本很低；
