Indlela yokukhetha inverter ye-photovoltaic yasekhaya

Njengoko i-photovoltaics ingena kumakhaya amaninzi, abasebenzisi abaninzi basekhaya baya kuba nombuzo ngaphambi kokufaka i-photovoltaics: Luluphi uhlobo lwe-inverter olufanele lukhethe?

Xa ufaka i-photovoltaics yasekhaya, le miba ye-5 ilandelayo kufuneka uyiqwalasele:

01

ukwandisa ingeniso

Yintoni i-inverter? Sisixhobo esiguqula amandla e-DC aveliswa ziimodyuli zelanga zibe ngamandla e-AC anokusetyenziswa ngabahlali. Ke ngoko, ukusebenza kakuhle kokuguqulwa kokuveliswa kombane ngumba ophambili xa kuthengwa i-inverter. Okwangoku, sele iyinto eqhelekileyo kumakhaya asekhaya ukuba amkele amandla aphezulu kunye namacandelo aphezulu angoku .Ke ngoko, amakhaya kufuneka aqale athathele ingqalelo ii-inverters ezilungiselelwe amacandelo aphezulu angoku, ezinokuguqulwa okuphezulu kokuguqulwa kunye neendleko eziphantsi.

Ukongeza, kukho iiparamitha ezininzi ezibalulekileyo zokuthelekisa:

Ukusebenza kakuhle kwe-inverter

Ukuphumelela okuphezulu kunye nokusebenza kakuhle kwe-MPPT ye-inverter zizibonakaliso ezibalulekileyo zokuqwalasela ukuveliswa kwamandla kwe-inverter. Okukhona ukusebenza ngokufanelekileyo, kokukhona ukomelela kokuveliswa kwamandla.

Uluhlu lwamandla ombane osebenzayo weDC

Ububanzi bombane osebenzayo weDC, okuthetha ukuqala kwangoko kunye nokuyeka kade, ixesha lokuvelisa amandla lide, kokukhona ukuveliswa kwamandla aphezulu.

Ukuchaneka kobuchwepheshe bokulandelela iMPPT

Itekhnoloji yokulandelela i-MPPT inokuchaneka okuphezulu, impendulo eguqukayo ekhawulezayo, inokulungelelanisa utshintsho olukhawulezayo ekukhanyeni, kunye nokuphucula ukusebenza kakuhle kokuveliswa kwamandla.

02

Ukuziqhelanisa nokuguquguquka

Imekobume yezikhululo zamandla zasekhaya intsonkothile. Iingxaki ezinjengee-terminals zegridi zamandla asemaphandleni kunye nokusetyenziswa kwamandla kuya kubangela i-inverter AC overvoltage, i-undervoltage kunye nezinye i-alamu. I-inverter kufuneka ibe nenkxaso yegridi ebuthathaka, uluhlu olubanzi lokuguquguquka kwamandla ombane wegridi, kunye nokuncipha kwe-overvoltage. , imbuyekezo yamandla esebenzayo kunye neminye imisebenzi yokunciphisa i-alamu yempazamo. Inani leMPPT likwangomnye wezalathi ezibalulekileyo ekufuneka ziqwalaselwe:uqwalaselo lweMPPT lwamajelo amaninzi lunokwakheka ngokuguquguqukayo ngokwemiba efana neemeko ezahlukeneyo, uphahla olwahlukeneyo, kunye neenkcukacha ezahlukeneyo zamacandelo.

03

ukufakela lula

Iimodeli ezincinci kunye nezilula kulula ukuzifaka. Kwangaxeshanye, kufuneka ukhethe i-inverter esele ibekwe kumzi-mveliso ngaphambi kokuba ushiye umzi-mveliso. Emva kokuba ifakwe kwikhaya lomsebenzisi, ingasetyenziswa emva kokukhanyisa, egcina ixesha lokulungisa kwaye ilungele ngakumbi.

04

ikhuselekile kwaye izinzile

Ekubeni ii-inverters ezininzi zifakwe ngaphandle, i-IP engenamanzi kunye nenqanaba lothuli liyisalathisi sokukhusela esingenako ukuhoywa, esinokukhusela ngokufanelekileyo i-inverter kwimiphumo eyingozi kwiindawo zemozulu ezimbi.Khetha i-inverter ene-IP65 okanye ngaphezulu ukuyaqinisekisa ukuba i-inverter isebenza ngokuqhelekileyo.

Ngokubhekiselele kwimisebenzi yokhuseleko, ukongeza kwimisebenzi eyimfuneko efana nokutshintsha kwe-DC, ukukhuselwa kwe-input overvoltage, ukhuseleko lwesekethe emfutshane ye-AC, ukhuseleko lwe-AC lokhuseleko olugqithisiweyo, kunye nokhuseleko lokumelana nokukhusela, kukho eminye imisebenzi emithathu ebaluleke kakhulu:

#

DC arc ubhaqo obukrelekrele AFCI

Inokuchonga ngokuchanekileyo imiqondiso ye-arcing, ivale ngokukhawuleza, iphephe umlilo, kwaye ikhusele ukhuseleko lomsebenzisi.

#

Umsebenzi wokurekhoda impazamo

Jonga kwaye urekhode amandla ombane kunye neefomati zangoku kwicala le-AC le-inverter ngexesha lokwenyani ukufumana ngokukhawuleza iingxaki.

#

I-Smart IV Ukuskena kunye nokuxilongwa

Iyakwazi ukukhangela iimpazamo zomtya ngokuchanekileyo kwaye ibone iingxaki. Ngeziqinisekiso ezininzi, isikhululo samandla sinokusebenza ngokuzinzileyo, ukunika abasebenzisi uxolo lwengqondo.

05

Ulawulo oluhlakaniphile

Kwixesha lanamhlanje ledijithali, izixhobo ezikrelekrele zinokubonelela abasebenzisi ngokulula ngakumbi. Iimpawu ze-inverterixhotyiswe ngeqonga lolawulo olukrelekrelesinokuzisa uncedo olukhulu kubasebenzisi kulawulo lwesikhululo samandla: Okokuqala, ungasebenzisa i-smartphone yakho ukujonga isikhululo samandla, ukujonga idatha yokusebenza kwesikhululo samandla nanini na naphi na, kwaye uqonde imeko yesikhululo samandla ngexesha elifanelekileyo. Kwangaxeshanye, abavelisi banokufumanisa iingxaki ngokuxilongwa kude, bahlalutye izizathu zokungaphumeleli, banike izisombululo, kwaye basombulule iingxaki bekude ngexesha elifanelekileyo.
