Uyafuna ukuxhuma amaphaneli elanga amabili ebhethrini elilodwa? Ufike endaweni efanele, ngoba sizokunikeza izinyathelo zokukwenza ngendlela efanele.
Ungawaxhuma kanjani ama-solar panel amabili kokugqwala kwebhethri elilodwa?
Uma uxhumanisa ukulandelana kwamaphaneli elanga, uxhuma iphaneli eyodwa kwelandelayo. Ngokuxhuma ama-solar panel, isifunda sezintambo sakhiwe. Intambo exhuma itheminali eyodwa yephaneli yelanga netheminali ephozithivu yephaneli elandelayo, nokunye. Ochungechungeni kungenye yezindlela ezilula zokuxhumanisa izinhlelo zakho zamandla elanga.
Isinyathelo sokuqala ukuxhuma ibhethri lakho kusilawuli sokushaja (MPPT noma i-PWM). Lona umsebenzi wokuqala okufanele wenziwe. Usengozini yokulimaza isilawuli sokushaja uma uxhuma amaphaneli elanga kuso.
Amanje isilawuli sakho sokushaja esisithumela kumabhethri sinquma ukuminyana kwezintambo. Isibonelo, i-Renogy Rover 20A inikeza ama-amps angu-20 ebhethri. Izintambo ezinomthamo okungenani ongu-20Amp ziyadingeka, kanjalo nokusetshenziswa kwefuse engu-20Amp kulayini. Okuwukuphela kwentambo okufanele ihlanganiswe yile ephozithivu. Uma usebenzisa intambo yethusi eguqukayo, uzodinga le ntambo ye-AWG12. Faka i-fuse eduze ngangokunokwenzeka ekuxhumekeni kwebhethri.
Bese, xhuma amaphaneli akho elanga. Kuleli qophelo, uzoxhuma amaphaneli akho elanga amabili.
Lokhu kungenziwa ngokulandelana noma ngokuhambisana. Uma uhlanganisa amaphaneli akho amabili ochungechungeni, i-voltage iyanda, kuyilapho ukuwaxhuma ngokuhambisana kukhulisa amandla amanje. Usayizi wentambo omncane uyadingeka uma ufaka izintambo ochungechungeni kunalapho izintambo zihambisana.
Izintambo ezivela kuphaneli yelanga zizoba zifushane kakhulu ukuthi zifinyelele isilawuli sakho sokushaja. Ungayixhuma kusilawuli sakho sokushaja usebenzisa le ntambo. Ukuxhumana kochungechunge kuzosetshenziswa isikhathi esiningi. Njengomphumela, sizoqhubeka futhi senze uxhumano lochungechunge. Beka ishaja eduze kwamabhethri ngangokunokwenzeka. Beka isilawuli sakho sokushaja eduze kwamaphaneli elanga amabili ngangokunokwenzeka ukuze unciphise ukulahleka kwezintambo. Ukuze unciphise ukulahlekelwa, susa noma yikuphi ukuxhumana okusele okuxhuma amaphaneli elanga kusilawuli sokushaja.
Bese, uxhuma noma yikuphi ukulayishwa kwe-DC okuncane kutheminali yesilawuli sokushaja. Uma ufuna ukusebenzisa i-inverter, yinamathisele kuzixhumi zebhethri. Cabangela umdwebo ongezansi njengesibonelo.
Umsinga onqamula izintambo unquma ubukhulu bawo. Uma i-inverter yakho idonsa ama-amps ayi-100, ikhebula lakho nezihlanganisi kufanele kulinganiswe ngokufanele.
Ungawasebenzisa kanjani ama-solar panel amabili ebhethri elilodwa?
Ukwenza kanjalo, kufanele uxhume amaphaneli ngokuhambisana ukuze unike amandla isistimu yebhethri engamawele. Xhuma ama-negative kuma-negative kanye nama-positives kuma-positives ukuze uxhume ama-solar panel amabili ngokuhambisana. Womabili amaphaneli kufanele abe ne-voltage efanayo efanelekile ukuze athole ukuphuma okuphezulu. Isibonelo, iphaneli yelanga ye-115W SunPower inezincazelo ezilandelayo:
I-voltage ephezulu elinganiselwe ngu-19.8 V.
Izinga eliphezulu elikhona = 5.8 A.
Amandla alinganiselwe aphezulu = Ama-Volts x Akhona = 19.8 x 5.8 = 114.8 W
Lapho ezimbili zalezi zingubo zokulala zixhunywe ngokuhambisana, amandla amakhulu alinganiselwe ngu-2 x 19.8 x 5.8 = 229.6 W.
Uma amaphaneli amabili enamaphuzu ahlukene okukhiphayo, iphaneli enevoltheji elinganiselwe efanelekile ephansi inquma i-voltage engcono kakhulu yesistimu. Udidekile? Ake sibone ukuthi kwenzekani lapho iphaneli yethu yelanga kanye nengubo yelanga kuxhunyiwe.
18.0 V iyona voltage esezingeni elifanele.
Isilinganiso esiphezulu samanje singu-11.1 A.
I-volts engu-19.8 yi-voltage elinganiselwe kakhulu.
Isilinganiso esiphezulu samanje singu-5.8 A.
Ukuwaxhuma ngezithelo ezifanayo:
(304.2 W) = amandla alinganiselwe aphezulu (18.0 x 11.1) Kanye (18.0 x 5.8)
Ngenxa yalokho, ukukhiqizwa kwezingubo zelanga kuzokwehliswa ngo-10% kuya ku-(18.0 x 5.8 =-RRB-104.4 W).
Iyiphi indlela engcono kakhulu yokuxhuma amaphaneli elanga angu-2?
Kunezindlela ezimbili ezihlukene zokuzixhuma, futhi sizoxoxa ngazo zombili lapha.
Njengamabhethri, amaphaneli elanga anamatheminali amabili: eyodwa iphozithivu nenye enegethivu.
Lapho i-terminal evumayo yephaneli eyodwa ixhunywe ku-terminal enegethivu yenye, uxhumano lochungechunge luyakhiqizwa. Isifunda somthombo we-PV siyasungulwa lapho amaphaneli elanga amabili noma ngaphezulu exhunywe ngale ndlela.
Lapho ama-solar panel exhunywe ochungechungeni, i-voltage iyanda ngenkathi i-amperage ihlala njalo. Lapho amaphaneli elanga amabili anezilinganiso zama-volts angu-40 nama-amps angu-5 exhunywe ochungechungeni, i-voltage yochungechunge ingama-volts angu-80 kanti i-amperage ihlala ku-5 amps.
I-voltage ye-array inyuswa ngokuxhuma amaphaneli ochungechungeni. Lokhu kubalulekile ngoba i-inverter ohlelweni lwamandla elanga kufanele isebenze ku-voltage ethile ukuze isebenze kahle.
Ngakho uxhuma amaphaneli akho elanga ochungechungeni ukuze uhlangabezane nezidingo zewindi le-voltage yokusebenza ye-inverter yakho.
Lapho amaphaneli elanga enezintambo ngokuhambisana, itheminali ephozithivu yephaneli eyodwa ixhumeka kutheminali ephozithivu yenye, futhi amatheminali anegethivu awo womabili amaphaneli ayaxhuma.
Imigqa ephozithivu ixhumeka kuxhumano oluhle ngaphakathi kwebhokisi lesihlanganisi, kuyilapho izintambo ezingezinhle zixhuma kusixhumi esinegethivu. Lapho amaphaneli amaningana exhunywe ngokuhambisana, isifunda sokuphuma se-PV siyakhiwa.
Lapho amaphaneli elanga exhunywe ochungechungeni, i-amperage iyakhuphuka ngenkathi i-voltage ihlala njalo. Ngenxa yalokhu, ukuhlanganisa amaphaneli afanayo ngokuhambisana njengangaphambili kwagcina i-voltage yesistimu iku-volts angu-40 kodwa kwenyusa i-amperage yaba ngu-10 amps.
Ungangeza amaphaneli elanga engeziwe akhiqiza amandla ngaphandle kokudlula imikhawulo ye-voltage yokusebenza ye-inverter ngokuxhuma ngokuhambisana. Ama-inverter nawo anqunyelwe yi-amperage, enganqotshwa ngokuxhuma amaphaneli akho elanga ngokuhambisana.
