Ixabiso eliphantsi! IiNkqubo zeGrid-Tied yasekhaya zinokuphuculwa zibe ziiNkqubo zokuGcinwa kwaMandla eKhaya

Q1: Yintoni ainkqubo yokugcina amandla ekhaya?

Inkqubo yokugcina amandla ekhaya yenzelwe abasebenzisi beendawo zokuhlala kwaye ngokuqhelekileyo idibaniswe nenkqubo ye-photovoltaic yasekhaya (PV) ukubonelela ngamandla ombane kumakhaya.

I-Q2: Kutheni abasebenzisi bongeza ukugcinwa kwamandla?

Inkuthazo ephambili yokongeza ukugcinwa kwamandla kukugcina iindleko zombane. Umbane wendawo yokuhlala usebenzisa iincopho ebusuku, ngelixa ukuveliswa kwePV kwenzeka emini, okukhokelela ekungahambelani phakathi kwemveliso kunye namaxesha okusebenzisa. Ugcino lwamandla lunceda abasebenzisi ukugcina umbane ogqithileyo emini ukuze bawusebenzise ebusuku. Ukongeza, iireyithi zombane ziyahluka imini yonke kunye nexabiso eliphezulu kunye nexabiso eliphantsi. Iinkqubo zokugcina amandla zinokuhlawulisa ngexesha le-off-peak ngokusebenzisa igridi okanye iipaneli ze-PV kunye nokukhupha ngexesha lamaxesha aphezulu, ngaloo ndlela ugweme iindleko eziphezulu zombane kwigridi kunye nokunciphisa ngokufanelekileyo amatyala ombane.

I-Q3: Yintoni inkqubo yegridi yendlu?

Ngokubanzi, iisistim ezibotshelelwe kwigridi yendlu zinokuhlelwa ngokweendlela ezimbini:

• Imowudi yokuFikelela ngokupheleleyo:Amandla e-PV afakwe kwigridi, kwaye ingeniso isekelwe kwisixa sombane esondliwe kwigridi.
• UkuziSetyenzisa NgeMowudi yokuNxibelela:Amandla e-PV asetyenziswa ikakhulu kusetyenziso lwasekhaya, nawo nawuphi na umbane ogqithileyo ofakwe kwigridi yengeniso.

I-Q4: Luluphi uhlobo lwenkqubo yegridi yendlu efanelekileyo yokuguqulwa kwindlela yokugcina amandla?Iinkqubo ezisebenzisa ukuzisebenzisa kunye nemowudi yokutya okugqithisileyo zifaneleke ngakumbi ukuguqulwa kwinkqubo yokugcina amandla. Izizathu zezi:

• Iinkqubo zemowudi yesondlo esipheleleyo zinexabiso elimiselweyo lokuthengisa umbane, ezinikezela ngembuyekezo ezinzileyo, ngoko ke uguqulo aluyomfuneko.
• Kwimodi yokutya epheleleyo, imveliso ye-PV inverter iqhagamshelwe ngokuthe ngqo kwigridi ngaphandle kokudlula kwimithwalo yasekhaya. Nangona ukongezwa kokugcinwa, ngaphandle kokutshintsha i-AC wiring, inokugcina kuphela amandla e-PV kwaye ayondle kwigridi ngamanye amaxesha, ngaphandle kokuvumela ukuzisebenzisa.

I-PV yasekhaya edibeneyo + neNkqubo yokuGcina amandla

Okwangoku, ukuguqula iisistim ezidityaniswe negridi yendlu kwiinkqubo zokugcina amandla ikakhulu zisebenza kwiinkqubo zePV zisebenzisa ukuzisebenzisela ngokugqithisileyo kwimowudi yokutya. Inkqubo eguquliweyo ibizwa ngokuba yi-PV yendlu edibeneyo + yenkqubo yokugcina amandla. Inkuthazo ephambili yokuguqulwa kukuncitshiswa kwenkxaso yombane okanye izithintelo zokuthengisa amandla abekwe ziinkampani zegridi. Abasebenzisi abaneenkqubo ze-PV zendlu esele zikhona banokucinga ngokungongeza ugcino lwamandla ukunciphisa ukuthengiswa kwamandla emini kunye nokuthengwa kweegridi zasebusuku.

Umzobo wePV yeKhaya eliBambiseneyo + neNkqubo yokuGcina amandla

01 Intshayelelo yeNkquboInkqubo yokugcina amandla edibeneyo ye-PV +, eyaziwa ngokuba yi-AC-coupled PV + inkqubo yokugcina amandla, ngokubanzi iqulethe iimodyuli ze-PV, i-inverter eboshwe ngegridi, iibhetri ze-lithium, i-AC-coupled storage inverter, imitha ehlakaniphile, i-CTs, igridi, imithwalo ebotshelelwe kwigridi, kunye nemithwalo engaphandle kwegridi. Le nkqubo ivumela amandla angaphezulu kwe-PV ukuba aguqulelwe kwi-AC nge-inverter eboshwe ngegridi kwaye emva koko kwi-DC yokugcinwa kwibhetri yi-inverter yokugcina edibeneyo ye-AC.

02 Ingqiqo yokusebenzaEmini, amandla e-PV anikezela kuqala umthwalo, emva koko ahlawule ibhetri, kwaye nayiphi na i-excess ifakwe kwigridi. Ebusuku, ibhetri ikhupha ukubonelela ngomthwalo, kunye naluphi na ukusilela okongezwa yigridi. Kwimeko yokuphuma kwegridi, ibhetri ye-lithium inika amandla kuphela imithwalo yegridi, kwaye imithwalo eboshwe ngegridi ayikwazi ukusetyenziswa. Ukongeza, inkqubo ivumela abasebenzisi ukuba babeke amaxesha abo okutshaja kunye nokukhupha umbane ukuhlangabezana neemfuno zabo zombane.

03 Iimpawu zeNkqubo

1. Iinkqubo ezikhoyo ze-PV ezifakwe kwigridi zingaguqulelwa kwiinkqubo zokugcina amandla kunye neendleko zotyalo-mali eziphantsi.
2. Ibonelela ngokhuseleko lwamandla oluthembekileyo ngexesha lokuphela kwegridi.
3. Iyahambelana neenkqubo zePV eziboshwe ngegridi ezivela kubavelisi abohlukeneyo.
