在使用太陽能充電控制器的過程中，一定要了解幾個電壓。

1、高壓保(bao)護電(dian)壓，防止(zhi)蓄電(dian)池(chi)過(guo)充，一(yi)般在15.5V。有(you)些控制(zhi)器沒有(you)這(zhe)(zhe)個功能(neng)，或(huo)者這(zhe)(zhe)個功能(neng)失效，導致電(dian)池(chi)鼓包甚至失效。

2、低(di)壓(ya)保(bao)護電(dian)(dian)(dian)壓(ya)，是(shi)為防(fang)止蓄電(dian)(dian)(dian)池(chi)(chi)過放而(er)設定的電(dian)(dian)(dian)壓(ya)。一般(ban)在111。V。同樣(yang)，如果沒(mei)有這個功(gong)能，或者元(yuan)器件的精度(du)不夠，電(dian)(dian)(dian)池(chi)(chi)就會過度(du)放電(dian)(dian)(dian)，通(tong)常電(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)壓(ya)低(di)于5V，很難再充回來，會導致電(dian)(dian)(dian)池(chi)(chi)報廢(fei)。

3、恢(hui)復(fu)電(dian)(dian)壓(ya)(ya)，這是(shi)指控(kong)制(zhi)器低(di)壓(ya)(ya)保護后，需要(yao)恢(hui)復(fu)到一定的電(dian)(dian)壓(ya)(ya)值才能正常工(gong)作，通常電(dian)(dian)壓(ya)(ya)為12.5V，如(ru)果沒有(you)達到這個低(di)壓(ya)(ya)值，控(kong)制(zhi)器就無(wu)法(fa)自動恢(hui)復(fu)工(gong)作。

有些(xie)人通常(chang)更長時間使用(yong)(yong)電(dian)(dian)(dian)池(chi)，通常(chang)會(hui)(hui)咨詢(xun)我(wo)們(men)(men)，電(dian)(dian)(dian)池(chi)的(de)低(di)(di)壓(ya)保(bao)護電(dian)(dian)(dian)壓(ya)是(shi)11V，能(neng)(neng)不(bu)(bu)能(neng)(neng)幫(bang)我(wo)調(diao)低(di)(di)一點，比如(ru)9V，這樣(yang)我(wo)們(men)(men)的(de)電(dian)(dian)(dian)池(chi)就可以長時間使用(yong)(yong)了。我(wo)們(men)(men)給出的(de)答案是(shi)不(bu)(bu)能(neng)(neng)的(de)。因為111V電(dian)(dian)(dian)壓(ya)點是(shi)電(dian)(dian)(dian)池(chi)使用(yong)(yong)電(dian)(dian)(dian)量的(de)70%左右(you)。如(ru)果降低(di)(di)電(dian)(dian)(dian)壓(ya)，會(hui)(hui)導致電(dian)(dian)(dian)池(chi)長時間斷電(dian)(dian)(dian)，影(ying)響(xiang)電(dian)(dian)(dian)池(chi)壽(shou)命。我(wo)們(men)(men)所(suo)有的(de)低(di)(di)壓(ya)保(bao)護、高壓(ya)保(bao)護和恢(hui)復(fu)電(dian)(dian)(dian)壓(ya)值，我(wo)們(men)(men)通常(chang)不(bu)(bu)會(hui)(hui)按照客戶(hu)的(de)要求改(gai)變(bian)。
