I-inverter yelanga iguqula umbane othe ngqo (i-DC) kumbane otshintshanayo (AC).I-inverter licandelo lenkqubo ebalulekileyo kuba iiphaneli zelanga zenzelwe ukuguqula ukukhanya kwelanga kumandla e-DC.Nangona kunjalo, ikhaya lakho lifuna i-AC ukunika amandla zonke izibane zakho kunye nezixhobo zombane.I-inverter yelanga iguqula umbane we-DC oveliswe ngamapaneli elanga kwi-240V AC yombane, onokuthi usetyenziswe yipropati / indlu, ukuthunyelwa ngaphandle kwegridi, okanye ugcinwe kwinkqubo yokugcina ibhetri yelanga.
1.Ilanga liqaqamba kwiiphaneli zelanga ezivelisa umbane we-Direct Current (DC).
2.Umbane we-DC wondliwa kwi-inverter yelanga eyiguqulela kumbane we-240V 50Hz AC.
3.Umbane we-240V AC usetyenziselwa umbane kwizixhobo zombane ekhayeni lakho.
4.I-surplus yombane ibuyiselwa kwigridi engundoqo.
Iibhetri zasekhaya kunye neenkqubo ezixutyiweyo ziya zithandwa ngakumbi, kodwa iibhetri zisakhula, kwaye uninzi lofakelo lwelanga lusafuna inverter ezinikeleyo yelanga.
Inzuzo enkulu yenkqubo ye-PV ebanzi ngakumbi yesolar kukuba kuya kuba lula ukongeza ibhetri yelanga, sebenzisa amandla akho e-solar inverter ukuya kwinqanaba elipheleleyo, kwaye uvelise amandla amaninzi emini ukuze ungaxhomekeki kwigridi. umbane.Unokuqala ukwenza uninzi lwenkqubo yakho yePV yelanga ngokufaka ibhetri yelanga, njengeTesla Powerwall 2.
Iimveliso ezininzi ze-solar inverter nazo zine-monitor ye-Wi-Fi, ekunika idatha yexesha langempela malunga nombane welanga owenziweyo.Kungcono nangakumbi xa une solar panel enamandla enokulinganisa amandla asetyenziswa ukuvelisa umbane.
Isetyenziselwa ntoni isiguquli?
Yonke inkqubo yamandla elanga kufuneka ibe neziguquli zelanga.Benza imisebenzi emibini ebalulekileyo:
Ukuguqulwa ukusuka kwi-DC ukuya kwi-AC
Zonke iiphaneli zelanga zivelisa i-Direct Current (DC), ekufuneka iguqulwe ibe yi-alternating current (AC), uhlobo lombane elinokusetyenziswa likhaya lakho ngesiguquli selanga.
Eyona ndawo iphezulu yokuJonga iPower Point (MPPT)
Ubungakanani bokukhanya kwelanga kunye nobushushu bephaneli yelanga obuchaphazela indlela iipaneli zelanga ezisebenza kakuhle ngayo ukutshintsha imini yonke.Oku kuthetha ukuba i-voltage kunye neyangoku enokuthi ivelise iphaneli yelanga nayo inokutshintsha rhoqo.I-inverter yelanga ikhetha ngokuguquguqukayo umxube wezo zimbini eziza kubonelela ngombane ophezulu usebenzisa inkqubo eyaziwa ngokuba yi-Maximum Power Point (MPP) yokulandelela.
Iikhrayitheriya ezisetyenziselwa ukukhetha ezona ziguquli-langa zibalaseleyo
Ukukhetha i-inverter yelanga kunokufezekiswa ngokuphonononga le migaqo ilandelayo.
1.Ukusebenza kakuhle, umgangatho kunye nokuthembeka

Abaguquli beentambo
Olona hlobo luqhelekileyo loguqulo lwelanga olusetyenziswa kwiinkqubo zephaneli yelanga yokuhlala yi-inverter yomtya kuba ufakelo ngalunye ludla ngokubiza enye.Iintambo ezininzi zeepaneli zelanga zidibanisa kwi-inverter enye.Emva koko, ukusetyenziswa kwasekhaya, iguqula i-DC ibe yi-AC.
Iziguquli ezincinci
Iphaneli nganye yelanga idinga inverter encinci ebizwa ngokuba yi-microinverter ukunyusa amandla ayo kwinqanaba lemodyuli.Nokuba kukho i-shading engaphelelanga, ipaneli nganye yelanga isavelisa umbane omninzi.Isiphumo sombane sephaneli nganye siphuculwe kusetyenziswa i-microinverter ukwandisa imveliso.Ekubeni i-micro-inverter nganye iqhagamshelwe kwenye, inkqubo igcina ukuguqula i-DC kwi-AC nokuba i-microinverter enye iyasilela.
Iziguquli eziphambili
Nangona zinkulu kwaye zikwazi ukugcina umtya ongaphezulu kwesinye endaweni nje enye, zifana ngokusondeleyo neziguquli zeentambo.
Ngokuchaseneyo ne-string inverters, iintambo zangaphakathi zidityaniswe kwi-bix, kunye namandla e-DC ahamba ukuya kwibhokisi ye-inverter ephakathi, apho iguqulwa ibe ngumbane we-AC.Ezi ikakhulu zisebenzela ishishini kuneenjongo zasekhaya.Ezi ziqhelekile kumaziko orhwebo kunye neefama zomgangatho oluncedo welanga.
I-inverter esekwe kwibhetri
Ibhanki yebhetri iyimfuneko ukuze ii-inverters zebhetri zisebenze.Iguqula umbane we-DC webhanki yebhetri ube ngamandla e-AC.Banokuhambisa umbane nangexesha lokucima kombane njenge-hybrid inverters.Iziguquli zebhetri zine-drawback yokuphazamisa ifowuni, irediyo, kunye nolwamkelo lukamabonakude ngenxa yengxolo yabo.Ukufakela amaza e-sine kuya kukunceda ukunciphisa ukuphazamiseka.
Isilungisi samandla
Izilungisi zamandla zinokufakwa kwiinkqubo ezineentambo zeepaneli kunye ne-inverter yomtya nangona zingezizo ii-inverters.Njengama-microinverters, baqinisekisa ukuba imveliso yeepaneli zelanga eziseleyo kumtya aziyi kuchaphazeleka ukuba enye yeepaneli inombala, imdaka, okanye iyasilela ngenye indlela.
Iinkqubo zeSolar PV kunye nee-inverters ezifunekayo
Ii-inverters eziboshwe ngegridi zenzelwe iinkqubo zelanga eziboshwe ngegridi, olona hlobo luqhelekileyo lwenkqubo.Xa kuyimfuneko, bangenisa umbane osetyenziswayo kwigridi kwaye bagcine ukusebenzisana kweendlela ezimbini kunye nayo, ukuthumela amandla elanga kuwo.
Ii-inverters zeHybrid zisebenza kunye neenkqubo zesolar ezixubeneyo, ezikwabizwa ngokuba zii-inverters zemowudi ezininzi, ii-inverters ezilungele ibhetri okanye iinkqubo zesolar-plus-storage.Bangakwazi ukuhlawula kunye nokutsala umbane kwilungiselelo lebhetri kwaye banomsebenzi ofanayo kunye ne-grid-tie inverter.
Iziguquli zegridi ezingasebenziyo zisetyenziswa kwiinkqubo zelanga ezingaphandle kwegrid, ezikwaziwa ngokuba ziinkqubo zamandla elanga ezizimeleyo, ukubonelela ngamandla okuxhasa ngexesha lokuphela kwegridi.
I-inverter ye-off-grid ayinakudityaniswa kwigridi kwaye kufuneka ibe ne-backup yebhetri ukuze isebenze.
