Watts yog amps x volts. Yog li ntawd yog koj muaj hais tias 600CCA (txias cranking amps) tsheb roj teeb , ces nws tuaj yeem muab txog 600 x 12 = 7200 watts rau ob peb vib nas this xav tau los pib tsheb.

Ib yam li ntawd, muaj pes tsawg watts yog lub tsheb roj teeb?

Coj tus qauv tsheb roj teeb . Nws yog ntsuas ntawm 45 amp / teev. Qhov ntawd txhais tau tias nws tuaj yeem crank tawm 2.25 amps rau 20 teev. Tsis tas li ntawd nws yuav pib tawm ntawm 12.9 volts thiab poob mus txog 11 volts, nruab nrab ntawm 12 volts thaum lub sijhawm.

Ib tus kuj yuav nug, pes tsawg lub roj teeb kuv xav tau rau 2000 watt inverter? Yog tias koj tshaj tawm qhov inverter ntawm 2000 watts, koj tab tom rub 2000 watts / 12 volts = np 166.6 DC amps ib teev. Yog tias koj siv 200 amp 12 roj teeb volt koj yuav faib 200 amp roj teeb / 166.6 amps = 1.2 teev sijhawm ua haujlwm.

Ib sab saum toj no, pes tsawg watts yog 12 volt roj teeb?

Yog tias lub zog tso zis tsis nyob ntawm 12v, ces peb yuav thim rov qab qhov sib npaug zog ua 12 * 40 = 480WH. Qhov no txhais tau tias lub roj teeb tuaj yeem muab tau 480 kwv rau 1 teev. 40AH (Amp Teev Sijhawm) /4.16Amps = 9.6 teev, lossis 9 teev thiab 36 feeb. lossis 480WH (Watt Teev Sijhawm)/ 50 (Watts) = 9.6 teev, lossis 9 teev thiab 36 feeb.

Muaj pes tsawg watts yog 12v 100ah roj teeb?

Tus neeg siv lub zog me me yog 1.2 watt LED teeb khiav ntawm a 12v zog Lub zog siv hluav taws xob yuav siv 1.2W / 12 v = 0.1 hli. Yog li a 100 aw (amp teev) roj teeb yuav kav ntev li 1000 teev. Ib qho piv txwv me ntsis txawv yog 60 watt fridge khiav ntawm ib 12 volt fais fab mov siv 60/12 = 5 amps, tab sis tsuas yog thaum lub cav khiav.
