Qhov hluav taws xob ua tau zoo ntawm photovoltaic hlws ris lub thawv feem ntau suav nrog kev ua haujlwm voltage, ua haujlwm tam sim no, hnub ci hlaus ntim lub thawv tiv thaiv thiab lwm yam tsis suav. Txhawm rau ntsuas seb lub pob hlws tsim tau zoo li cas, hnub ci lub thawv hluav taws xob kev ua tau zoo yog qhov sib txuas tseem ceeb. Thaum rov qab qhov hluav taws xob siv rau ob qho kawg ntawm lub diode tau mus txog ib qho nqi, lub hnub ci lub thawv lub raj yuav tawg thiab poob nws txoj kev ua tsis tau coj mus muag. Txhawm rau kom muaj kev nyab xeeb ntawm kev siv, qhov siab tshaj qhov rov qab ua hauj lwm tus nqi hluav taws xob tau teev, lub hnub ci hlaws ris lub thawv uas yog qhov ntau qhov siab tshaj plaws uas cov khoom sib txuas ntawm photovoltaic hlws ris lub thawv tuaj yeem tiv taus thaum ua haujlwm tsis ua haujlwm. Tam sim no, hnub ci hlais ntim lub thawv ua hauj lwm ntawm lub thawv txuas yog 1000V (DC).
Kev xaiv ntawm txoj kev bypass diode feem ntau ua raws cov ntsiab lus hauv qab no: lub peev xwm voltage muaj ob zaug qhov siab tshaj plaws ua hauj lwm voltage; qhov kev sib tshuam kub yuav tsum siab tshaj qhov ntsuas kub tiag tiag; lub tshav pob tiv thaiv lub thawv thermal tiv thaiv yog me me; Me me poob;
