Ngaba uyafuna ukudibanisa iiphaneli zelanga ezimbini kwibhetri enye?Ufike kwindawo elungileyo, kuba siya kukunika amanyathelo okuyenza ngokufanelekileyo.
Indlela yokudibanisa iiphaneli ezimbini zelanga kwirust yebhetri enye?
Xa udibanisa ulandelelwano lweepaneli zelanga, udibanisa iphaneli enye ukuya kwelandelayo.Ngokudibanisa iipaneli zelanga, isiphaluka somtya siyakhiwa.Ucingo oludibanisa i-terminal enye yepaneli yelanga kunye ne-positive terminal yepaneli elandelayo, njalo njalo.Kuthotho yenye yeendlela ezilula zokudibanisa iinkqubo zakho zamandla elanga.
Inyathelo lokuqala kukudibanisa ibhetri yakho kwisilawuli sokutshaja (MPPT okanye PWM).Lo ngumsebenzi wokuqala ekufuneka ugqitywe.Usengozini yokwenzakalisa umlawuli wentlawulo ukuba uqhagamshela iipaneli zelanga kuyo.
Umsinga othunyelwa ngumlawuli wakho wentlawulo kwiibhetri umisela ukuxinana kweengcingo.Ngokomzekelo, i-Renogy Rover 20A inikezela ngee-amps ezingama-20 kwibhetri.Iingcingo ezinobuncinci be-20Amp umthamo wokuthwala ziyimfuneko, njengoko kusetyenziswa i-20Amp fuse kumgca.Olona cingo kufuneka ludityaniswe lulo olu-positive.Ukuba usebenzisa ucingo lobhedu olubhetyebhetye, uya kufuna olucingo lwe-AWG12.Faka i-fuse ngokusondeleyo kangangoko kunokwenzeka kuqhagamshelwano lwebhetri.
Emva koko, qhagamshela iiphaneli zakho zelanga.Kweli nqanaba, uya kudibanisa iiphaneli zakho ezimbini zelanga.
Oku kunokwenziwa ngokulandelelana okanye ngokuhambelanayo.Xa ujoyina iiphaneli zakho ezimbini kuthotho, i-voltage iyanda, ngelixa ukudibanisa ngokuhambelanayo kwandisa okwangoku.Ubungakanani bentambo encinci buyimfuneko xa i-wiring kwi-series kunokuba i-wiring in parallel.
Iingcingo ezisuka kwipaneli yelanga ziya kuba mfutshane kakhulu ukufikelela kwisilawuli sakho sokutshaja.Ungayiqhagamshela kwisilawuli sakho sokutshaja usebenzisa le ntambo.Uqhagamshelo lothotho luya kusetyenziswa uninzi lwexesha.Ngenxa yoko, siya kuqhubekeka kwaye senze unxibelelwano lothotho.Beka itshaja kufutshane neebhetri kangangoko.Beka isilawuli sakho sokutshaja kufutshane neephaneli zesola ezimbini kangangoko unakho ukunciphisa ilahleko yocingo.Ukunciphisa ilahleko, susa naluphi na uxhulumaniso oluseleyo oludibanisa iipaneli zelanga kwisilawuli sentlawulo.
Emva koko, qhagamshela nayiphi na imithwalo emincinci ye-DC kwi-terminal yomthwalo wesilawuli.Ukuba ufuna ukusebenzisa isiguquli-guquli, sincamathele kwizihlanganisi zebhetri.Qwalasela lo mzobo ungezantsi njengomzekelo.
Umsinga ohamba ngapha kweengcingo umisela ubungakanani bayo.Ukuba i-inverter yakho itsala ii-amps ezili-100, intambo yakho kunye nokudibanisa kufuneka kulinganiswe ngokufanelekileyo.
Uzisebenzisa njani iipaneli zelanga ezimbini kwibhetri enye?
Ukwenza njalo, kufuneka uqhagamshele iiphaneli ngokunxuseneyo ukunika amandla isistim yebhetri engamawele.Xhuma i-negatives kwi-negatives kunye ne-positives kwi-positives ukudibanisa iipaneli ezimbini zelanga ngokufanayo.Zombini iipaneli kufuneka zibe namandla ombane alinganayo ukuze ufumane imveliso ephezulu.Umzekelo, iphaneli yelanga ye-115W SunPower inezi nkcukacha zilandelayo:
Amandla ombane aphezulu kwi-19.8 V.
Inqanaba eliphezulu elikhoyo = 5.8 A.
Awona mandla alinganisiweyo aphezulu = IiVolts x Ekhoyo = 19.8 x 5.8 = 114.8 W
Xa ezimbini kwezi ngubo ziqhagamshelwe ngokunxuseneyo, awona mandla amakhulu alinganisiweyo yi-2 x 19.8 x 5.8 = 229.6 W.
Ukuba iipaneli ezimbini zinamanqaku ahlukeneyo aphumayo, indawo yolawulo enelona voltheji isezantsi ifanelekileyo imisela owona mbane ubalaseleyo wenkqubo.Ngaba udidekile?Makhe sibone ukuba kwenzeka ntoni xa iphaneli yethu yelanga kunye nengubo yelanga ziqhagamshelwe.
I-18.0 V yeyona ndawo ifanelekileyo yombane.
Olona luhlu luphezulu lwangoku luyi-11.1 A.
I-19.8 volts ngowona mandla ombane aphezulu.
Umlinganiselo wangoku ophezulu ngu-5.8 A.
Ukuzidibanisa kwimveliso ehambelanayo:
(304.2 W) = ubuninzi bomlinganiselo wamandla (18.0 x 11.1) Plus (18.0 x 5.8)
Ngenxa yoko, imveliso yeengubo zelanga iya kuthotywa nge-10% ukuya (18.0 x 5.8 =-RRB-104.4 W).
Yeyiphi eyona ndlela yokudibanisa iiphaneli zesola ezi-2?
Kukho iindlela ezimbini ezahlukeneyo zokuzidibanisa, kwaye siza kuzixubusha zombini apha.
Njengeebhetri, iiphaneli zelanga zineetheminali ezimbini: enye intle kunye nenye enegethivu.
Xa i-terminal evumayo yepaneli enye idityaniswe kwi-terminal engafanelekanga yenye, uxhulumaniso lwechungechunge luyaveliswa.Isiphaluka somthombo we-PV sisekwe xa iipaneli zelanga ezimbini okanye ngaphezulu zixhunyiwe ngolu hlobo.
Xa iipaneli zelanga zidityanisiwe kuthotho, i-voltage iyanda ngelixa i-amperage ihlala ingatshintshi.Xa iipaneli ezimbini zelanga ezinemilinganiselo ye-40 volts kunye ne-5 amps zixhunyiwe kwichungechunge, i-voltage ye-series i-voltage ye-80 kunye ne-amperage ihlala kwi-5 amps.
I-voltage ye-array inyuswa ngokudibanisa iipaneli kwiichungechunge.Oku kubalulekile kuba i-inverter kwinkqubo yamandla elanga kufuneka isebenze kumbane ochaziweyo ukuze isebenze ngokufanelekileyo.
Ke uqhagamshela iiphaneli zakho zelanga kuthotho ukuhlangabezana neemfuno zefestile zombane osebenzayo we-inverter yakho.
Xa iipaneli zelanga zifakwe kwi-parallel, i-terminal evumayo yepaneli enye idibanisa kwi-terminal evumayo yenye, kunye ne-negative terminals zombini iipaneli zidibanisa.
Imigca emihle idibanisa uxhulumaniso olulungileyo ngaphakathi kwebhokisi yokudibanisa, ngelixa iingcingo ezingalunganga zidibanisa kwikhonkco elibi.Xa iipaneli ezininzi zidibaniswe ngokufanayo, isiphaluka se-PV sokuphuma siyakhiwa.
Xa iipaneli zelanga zidibaniswe kuthotho, i-amperage iphakama ngelixa i-voltage ihlala ingatshintshi.Ngenxa yoko, ukufakwa kweengcingo kwiipaneli ezifanayo ngokunxuseneyo njengangaphambili kugcinwe amandla ombane we-voltage kuma-40 volts kodwa konyusa i-amperage ukuya kwi-amps ezili-10.
Unokongeza iipaneli zelanga ezongezelelweyo ezivelisa amandla ngaphandle kokugqithisa izithintelo zombane osebenzayo we-inverter ngokuqhagamshela ngokuhambelana.Ii-inverters zikwanqunyelwe yi-amperage, enokuthi yoyiswe ngokudibanisa iipaneli zakho zelanga ngokunxuseneyo.
