Imiba ephambili ekumiseleni ubungakanani beCable yeSolar

Ubudlelwane phakathi kweWatts, iVoltage, kunye neAmperage

Ukuqonda unxibelelwano phakathi kwee-watts, i-voltage, kunye ne-amperage kubalulekile xa ukhetha intambo yelanga elungileyo. IiWatts zilinganisa amandla ewonke avelisiweyo sisixokelelwano sakho selanga. I-Voltage ibhekisa kumandla ombane wenkqubo yakho, ngelixa i-amperage ibonisa ukuqukuqela kwangoku kwintambo. Ukubala okwangoku, yahlula i-watts iyonke nge-voltage yenkqubo. Ngokomzekelo, iphaneli yelanga ye-200-watt esebenza kwi-volts ye-12 ivelisa malunga ne-16.7 amps (200 ÷ 12 = 16.7). Olu balo lukunceda ukuba ubone ubuncinci bangoku intambo yakho kufuneka iphathe ngokukhuselekileyo.

Iinkqubo zamandla ombane aphezulu ngokuqhelekileyo zifuna umsinga omncinci kwimveliso yamandla efanayo. Oku kukuvumela ukuba usebenzise iintambo ezincinci, ezinokugcina iindleko. Nangona kunjalo, hlala uqinisekisa ukuba ubungakanani bentambo buhambelana ne-amperage ukuthintela ukufudumeza okanye ukulahleka kwamandla. Ngokuqonda olu budlelwane, unokwenza izigqibo ezinolwazi malunga neemfuno zakho zentambo yelanga.

Impembelelo yoBubude beCable kunye neVoltage Drop

Ubude bekhebula buchaphazela kakhulu ukusebenza kwesixokelelwano sakho selanga. Iintambo ezinde zonyusa ukunganyangeki, okukhokelela ekuweni kombane. Ukuhla kwe-voltage kunciphisa ukusebenza kwenkqubo yakho ngokuthoba umthamo wamandla anikezelwe kwizixhobo zakho. Ukunciphisa oku, kufuneka ukhethe ubungakanani bentambo obuhlawulela ukuhla kwamandla ombane ngaphezu kobude bentambo.

Unokuqikelela ukuhla kwamandla ombane usebenzisa le fomyula: I-Voltage Drop = (I-Amperage × Ubude beCable × Ukumelana noBubude beyunithi) ÷ 1000. Ngokomzekelo, ukuba inkqubo yakho isebenza kwii-amps ezili-10 ngaphezu kwentambo ye-50-foot, kwaye ukuxhathisa yi-0.1 ohms nganye unyawo, ukuhla kwamandla ombane kuya kuba yi-0.5 volts. Ukugcina i-voltage drop phantsi kwe-2-3% iqinisekisa ukusebenza kakuhle kwenkqubo. Ukukhetha intambo engqindilili kunciphisa ukuxhathisa kwaye inceda ukugcina ukusebenza kakuhle, ngakumbi ukubaleka ixesha elide.

Ukubaluleka kweMigangatho ye-American Wire Gauge (AWG).

Imigangatho ye-American Wire Gauge (AWG) inika indlela ethembekileyo yokumisela ubungakanani obufanelekileyoyentambo yelanga. I-AWG ilinganisa ubukhulu bentambo, ngamanani amancinci abonisa iingcingo ezityebileyo. Iintambo ezityebileyo zinokubamba imisinga ephezulu kwaye zinciphise ukuhla kwamandla ombane, zizenze zilungele iinkqubo ezinkulu okanye iintambo ezinde.

Ngokomzekelo, intambo ye-14 ye-AWG ifanelekile kwiinkqubo ezine-amperage ephantsi, njenge-100-watt panel yelanga. Ngokwahlukileyo, intambo ye-10 ye-AWG isebenza ngcono kwiinkqubo ezivelisa imisinga ephezulu, njengephaneli ye-300-watt. Ngalo lonke ixesha ubhekisele kwitshathi ye-AWG okanye ubungakanani bocingo lokubala ukutshatisa ubungakanani bentambo kwiimfuno zesixokelelwano sakho. Ukulandela imigangatho ye-AWG iqinisekisa ukuba inkqubo yakho yelanga isebenza ngokukhuselekileyo nangokufanelekileyo.

ISikhokelo seNyathelo ngeNyathelo sokuKhetha iCable yeSolar eLungileyo

Inyathelo loku-1: Bala i-Amperage iyonke yeSolar System yakho

Qala ngokumisela i-amperage epheleleyo eyenziwa yinkqubo yakho yelanga. Sebenzisa ifomula: Amps = Watts ÷ Voltage. Olu balo lukunceda ukuba uqonde umsinga oqukuqelayo ngentambo yakho yelanga. Umzekelo, ukuba i-solar panel yakho ivelisa i-300 watts kwaye isebenza kwii-volts ezili-12, okwangoku kuya kuba ngama-amps angama-25 (300 ÷ 12 = 25). Ukwazi eli xabiso liqinisekisa ukuba ukhetha ikhebula elinokusingatha umthwalo ngokukhuselekileyo.

Soloko ubandakanya umndilili wawo onke amalungu kwindlela yakho. Ukuba uneepaneli ezininzi eziqhagamshelwe ngokunxuseneyo, yongeza imisinga yazo kunye. Eli nyathelo libalulekile kuba ukujongela phantsi i-amperage kunokukhokelela ekushiseni kakhulu okanye kumonakalo kwinkqubo yakho.
