IiNdlela zePaneli yeSola kunye neziQhagamshelwano ziQhagamshela njani kwiModyuli yePV?

Uninzi lweepaneli zelanga ezinamandla aphezulu zenziwe ngeentambo zePV ezineziqhagamshelo zeMC4 eziphelweni.Kwiminyaka edlulileyo, iimodyuli ze-PV zelanga zinebhokisi ye-junction ngasemva kunye nezifakeli ezifunekayo ukudibanisa ngesandla iintambo kwii-terminals ezintle kunye nezibi.Le ndlela isasetyenziswa, kodwa ikhutshwa kancinci kancinci.Iimodyuli zelanga zanamhlanje zikholisa ukusebenzisaIiplagi zeMC4kuba benza iingcingo zoluhlu lwePV lube lula kwaye lukhawuleze.Iiplagi zeMC4 ziyafumaneka ngezitayile zamadoda nabasetyhini zokuqhawula kunye.Bahlangabezana neemfuno zeKhowudi yoMbane yeSizwe, i-UL idweliswe, kwaye yindlela ekhethiweyo yokudibanisa kubahloli bombane.Ngenxa yendlela yokutshixa iziqhagamshelo zeMC4, azinakutsalwa, zizenze zilungele imeko yangaphandle.Iziqhagamshelo zinokuqhawulwa kunye nekhethekileyoIsixhobo sokuqhawula i-MC4.

Ufakwa njani kwi-MC4 enePaneli zeSolar kuthotho?

Ukuba uneepaneli zelanga ezimbini okanye ngaphezulu ukuba ziqhagamshelwe kuthotho, usebenzisa i-MC4 PV isinxibelelanisi yenza uthotho lube lula.Jonga imodyuli yokuqala yePV kumfanekiso ongezantsi kwaye uya kubona ukuba ineentambo ezimbini zePV zelanga ezandisa ibhokisi yokuhlangana.Enye intambo ye-PV yi-DC positive (+) kwaye enye yi-DC negative (-).Ngokuqhelekileyo, i-MC4 ikhonkco yowesifazane idibaniswa nekhebula elihle kwaye ikhonkco lendoda lidibene nentambo engafanelekanga.Kodwa oku akusoloko kunjalo, ngoko ke kungcono ukujonga iimpawu kwibhokisi ye-PV yokuhlangana okanye usebenzise i-voltmeter yedijithali ukuvavanya i-polarity.Uqhagamshelo oluluthotho kuxa isikhokelo esilungileyo kwiphaneli enye yelanga iqhagamshelwe kwisikhokelo esingalunganga kwenye indawo yolawulo lwelanga, isidibanisi se-MC4 esiyindoda siya kungena ngqo kwisinxibelelanisi sowesifazane.Lo mzobo ungezantsi ubonisa indlela iimodyuli zeMC4 eziqhagamshelwe ngayo kuthotho:

Njengoko kubonisiwe, iipaneli ezimbini zelanga zidibaniswe ngokulandelelana ngamanyathelo amabini, okwandisa i-voltage yesiphaluka.Ngokomzekelo, ukuba iimodyuli zakho ze-PV zilinganiswe kwi-volts ye-18 kumandla aphezulu (Vmp), ngoko ezimbini kuzo zixhunywe kwichungechunge ziya kuba yi-36 Vmp.Ukuba udibanisa iimodyuli ezintathu kuchungechunge, i-Vmp iyonke iya kuba yi-54 volts.Xa isiphaluka sidibaniswe kwichungechunge, ubuninzi bamandla akhoyo (Imp) iya kuhlala ifana.

Ufakwa njani kwi-MC4 enePaneli zeSolar ngokuFanayo?

I-parallel wiring idinga ukudibanisa iingcingo ezilungileyo kunye kunye neengcingo ezimbi kunye.Le ndlela iya kwandisa i-current kumandla aphezulu (Imp) ngelixa igcina i-voltage rhoqo.Umzekelo, masithi iiphaneli zakho zesola zithelekelwe i-8 amps Imp, kunye ne-18 volts Vmp.Ukuba ezimbini zazo zixhunyiwe ngokufanayo, i-amperage iyonke iya kuba yi-16 amps Imp kwaye i-voltage iya kuhlala kwi-18 volts Vmp.Xa udibanisa iipaneli zelanga ezimbini okanye ngaphezulu ngokuhambelanayo, uya kufuna ezinye izixhobo ezongezelelweyo.Ukuba usebenzisa iipaneli zelanga ezimbini kuphela, eyona ndlela ilula kukusebenzisa iipaneli zelangaMC4 isidibanisi sesebe.Ngokucacileyo, awukwazi ukudibanisa izinxibelelanisi ezimbini zamadoda okanye izinxibelelanisi ezimbini zabasetyhini kunye, ke siza kuyenza loo nto ngesidibanisi sesebe lePV.Kukho izihlanganisi ezimbini ezahlukeneyo zesebe.Olunye uhlobo lwamkela iziqhagamshelo ezimbini ze-MC4 zamadoda kwicala lokufaka kwaye ine-MC4 enye isinxibelelanisi esiyindoda kwimveliso.Olunye uhlobo lwamkela iziqhagamshelo zabasetyhini be-MC4 kwaye ine-MC4 enye isinxibelelanisi sabasetyhini kwimveliso.Ngokusisiseko, ulehlise inani leentambo ukusuka kwi-positive kunye ne-negative ezimbini ukuya kwenye i-positive kunye ne-negative enye.Njengoko umzobo uboniswe ngezantsi:

Ukuba unxulunyaniswa neemodyuli zePV ezingaphezulu kweembini okanye imitya ehambelanayo yeemodyuli, udinga ibhokisi yokudibanisa yePV.Ibhokisi yokudibanisa inomsebenzi ofanayo kunye nokudibanisa kwesebe lelanga.Izixhumi zesebe lelanga zifanelekile kuphela ukudibanisa iipaneli ezimbini zelanga ngokuhambelanayo.Inani elipheleleyo leepaneli zelanga ezinokudibaniswa ziya kuxhomekeka kwimilinganiselo yombane kunye nobukhulu bomzimba webhokisi lokudibanisa.Nokuba uqhagamshela iiphaneli zakho zelanga kunye nezihlanganisi zesebe okanye iibhokisi zokuhlanganisa, kufuneka wazi ukuba ungakhetha njani kwaye usebenzise iintambo zokongezwa zeMC4.

Isetyenziswa njani iCable MC4 Extension Cable?

    MC4 iintambo zokwandisa ilangazifana kakhulu ngengqiqo kwiintambo zokwandisa amandla.Ikhebula lokwandisa ilanga lifana nekhebula lokwandisa amandla, kunye nesiphelo sendoda kwelinye icala kunye nesetyhini kwelinye icala.Ziza ngobude obuninzi obahlukeneyo, ukusuka kwi-8 ukuya kwi-100 yeenyawo.Emva kokudibanisa iipaneli ezimbini zelanga kuchungechunge, kuya kufuneka usebenzise intambo yokwandisa amandla elanga ukuhambisa amandla apho izixhobo zombane zikhoyo (ngokuqhelekileyo i-circuit breakers kunye nezilawuli zelanga).Iinkqubo ze-Photovoltaic ezisebenzisa iipaneli zelanga ezimbini zihlala zisetyenziswa kwii-RVs kunye neenqanawa, ngoko izikhokelo zokwandisa ilanga zihlala zisetyenziswa kumgama wonke.

Xa usebenzisa iiphaneli zesola eluphahleni, umgama ekufuneka ihanjwe yintambo udla ngokuba mde kangangokuba ukusebenzisa intambo yolwandiso lwepaneli yelanga ayisasebenzi.Kule meko, iintambo zokwandisa zisetyenziselwa ukudibanisa iipaneli zelanga kwibhokisi yokudibanisa.Oku kukuvumela ukuba usebenzise iintambo ezingabizi kakhulu ngaphakathi kwemibhobho yombane ukugubungela umgama omkhulu ngexabiso eliphantsi kakhulu kuneentambo zeMC4.

Cinga ukuba ubude bekhebula bubonke obufunekayo kwiiphaneli ezimbini zelanga ukuya kwisixhobo sakho sombane ziinyawo ezingama-20.Into oyifunayo yintambo yokwandisa.Sinikezela ngentambo yokwandisa i-solar ye-50 eyona nto ingcono kule meko.Iiphaneli ezimbini zelanga ozidibanise kunye zinesikhokelo esilungileyo esine-MC4 yesiqhagamshelo samadoda kunye nesikhokelo esingalunganga esine-MC4 yokudibanisa yabasetyhini.Ukufikelela kwisixhobo sakho ngaphakathi kweenyawo ezingama-20, uya kufuna iintambo ezimbini zePV eziziimitha ezingama-20, enye inendoda enye nebhinqa.Oku kufezwa ngokusika i-50-foot extension ye-solar lead kwisiqingatha.Oku kuya kukunika i-25ft ehamba phambili kunye ne-MC4 eyindoda yokudibanisa kunye ne-25ft ekhokelayo kunye nekhonkco le-MC4 yowesifazane.Oku kukuvumela ukuba uqhagamshele kuzo zombini iinkokeli zepaneli yelanga kwaye kukunika intambo eyaneleyo yokufika kwindawo oya kuyo.Ngamanye amaxesha ukusika intambo phakathi akusoloko kusona isisombululo.Ngokuxhomekeke kwindawo yebhokisi yokudibanisa yePV, umgama osuka kwelinye icala lomtya wepaneli yePV ukuya kwibhokisi yokudibanisa unokuba mkhulu kunomgama ukusuka kwelinye icala lomtya wePV wepaneli ukuya kwibhokisi yomhlanganisi.Kule meko, kuya kufuneka unqumle intambo yolwandiso lwe-PV kwindawo evumela ukuba iziphelo ezimbini ezisikiweyo zifikelele kwibhokisi yokudibanisa, enegumbi elincinci lokudambisa.Njengoko kubonisiwe ngezantsi komzobo:

Kwiinkqubo ezisebenzisa iibhokisi zokuhlanganisa iPV, ukhetha ngokulula ubude obude ngokwaneleyo ukuba bupheliswe kwibhokisi yomhlanganisi xa usikiwe.Emva koko unokukrazula i-insulation kwiiphelo ezisikiweyo kwaye uziphelise kwi-busbar okanye i-breaker circuit.
