Kev suav lub zog:
Lub hnub ci hluav taws xob AC lub zog tsim hluav taws xob yog tsim los ntawm cov hnub ci vaj huam sib luag, cov tswj hwm, inverters thiab roj teeb;lub hnub ci DC lub zog tsim hluav taws xob tsis suav nrog lub inverter.Txhawm rau ua kom lub hnub ci hluav taws xob tsim hluav taws xob los muab lub zog txaus rau lub nra, nws yog ib qho tsim nyog yuav tsum xaiv txhua yam raws li lub zog ntawm cov khoom siv hluav taws xob.Siv 100W tso zis hluav taws xob thiab siv nws li 6 teev hauv ib hnub ua piv txwv los qhia txog txoj kev suav:
1. Ua ntej xam cov watt-teev noj ib hnub (nrog rau qhov poob ntawm inverter):
Yog hais tias qhov hloov dua siab tshiab ntawm lub inverter yog 90%, thaum lub hwj chim tso zis yog 100W, lub zog tsim nyog yuav tsum yog 100W / 90% = 111W;Yog tias siv 5 teev hauv ib hnub, kev siv hluav taws xob yog 111W * 5 teev = 555Wh.
2. xam lub hnub ci vaj huam sib luag:
Raws li lub hnub ci zoo hnub ci lub sij hawm ntawm 6 teev, thiab txiav txim siab qhov kev them nqi thiab qhov poob thaum lub sij hawm them nqi, cov zis hluav taws xob ntawm lub hnub ci vaj huam sib luag yuav tsum yog 555Wh / 6h / 70% = 130W.Ntawm lawv, 70% yog lub zog tiag tiag siv los ntawm lub hnub ci vaj huam sib luag thaum lub sijhawm them nyiaj.
