Lub zog suav: Lub hnub ci AC lub zog hluav taws xob yog tsim los ntawm cov hnub ci ci, kab hluav taws xob vaj huam sib luag tswj hwm, inverter thiab cia roj teeb; hnub ci DC hluav taws xob tsim hluav taws xob tsis suav nrog lub zog. Txhawm rau kom lub hnub ci hluav taws xob tsim hluav taws xob muaj hluav taws xob txaus rau lub nra, lub hnub ci vaj huam sib luag nws yog qhov tsim nyog yuav tau xaiv ntau yam khoom siv kom tsim nyog raws li lub zog ntawm cov cuab yeej hluav taws xob. Siv 100W tso zis hluav taws xob thiab siv 6 teev nyob rau ib hnub ua piv txwv los qhia txog txoj kev suav kev xam: Ua ntej, hnub ci vaj huam sib luag laij lub hnub siv hluav taws xob teev ib hnub (suav nrog qhov poob ntawm lub inverter): Yog hais tias hloov dua siab tshiab ntawm lub inverter yog 90% , hnub ci vaj huam sib luag Tom qab ntawd thaum lub zog tsim hluav taws xob yog 100W, qhov yuav tsum tawm hluav taws xob tseeb yuav tsum yog 100W / 90%=111W; yog tias nws siv rau 5 teev hauv ib hnub, hnub ci vaj huam sib luag tawm lub zog hluav taws xob yog 111W * 5 teev=555Wh.
Txheeb xyuas cov hnub ci hnub ci: Xam raws li cov hnub zoo hnub ntawm 6 teev, hnub ci vaj huam sib luag coj mus rau hauv qhov kev pabcuam kev them nyiaj thiab kev them
