Ngelixa abantu abaninzi kwihlabathi liphela bekhuthazwa ukuba bafake iinkqubo zamandla elanga kuphahla lwezindlu zabo okanye kwenye indawo kwindawo yabo, akunjaloiinkqubo zebhetri zelanga zasekhayayokugcina. Nangona kunjalo, indima yabo kulwakhiwo lwalo naluphi na ufakelo ibalulekile, ikakhulu kuba baneendlela ezi-4 ezibalaseleyo zokusebenza: Ukonyuka kwePV Ukuzityela / ukuPheka Ukutya okuPhambili Backup Power Iinkqubo ze-Off-grid Ukunyusa iPV Self-consumption / Peak Regulation Sonke siyazi ukuba iinkqubo zamandla elanga azikwazi ukuhlangabezana neemfuno zombane ebusuku, xa uninzi lokusetyenziswa kombane ebusuku, ngoko enye yeenjongo zokufakela inkqubo yebhetri yelanga kwi-PV yakho kukwandisa ukusetyenziswa kwakho kwePV. izinga. Xa usebenza kule modi, i-inverter iya kugcina ubuninzi bamandla e-PV avelisiweyo ngokusemandleni. Oku kuthetha ukuba wonke umbane ongasetyenziswanga (ofunwayo) yindlu emini uya kugcinwa kwibhanki yebhetri ye-lithium. Ukuba awunayo ibhanki yebhetri ye-lithium efakwe, ngoko amandla aseleyo aya kuthunyelwa kwi-utility kule modi. Le ndlela ifanelekile kubantu abafuna ukusebenzisa amandla abo ePV ebusuku xa amandla egridi ebiza kakhulu. Sibiza le ngcamango "i-arbitrage yamandla" okanye "ukuphakama", kwaye ngokunyuka kwamaxabiso amandla namhlanje, sikholelwa ukuba abantu abaninzi banokukhetha ukusebenzisa le modi kwezinye iindlela. Ukutya okuPhambili Xa le ndlela ivuliwe, inkqubo iya kubeka phambili ukunika amandla kwigridi. Oku kuthetha ukuba ibhetri ayisayi Kutshajwa okanye ikhutshwe ngaphandle kokuba ixesha lokuTshaja livuliwe kwaye lilungiswe kakuhle. Imowudi yokuNxibelela ngokuFundisa yeyona ilungileyo kubantu abaneenkqubo ezinkulu zePV ngokunxulumene nokusetyenziswa kwamandla kunye nobungakanani bebhetri. Umba wolu seto kukuthengisa amandla amaninzi kangangoko kunokwenzeka kwigridi kwaye usebenzise kuphela ibhetri kwiifestile ezincinci zexesha okanye xa amandla egridi elahlekile. Backup Power Kwiindawo ezihlala zihlaselwa yientlekele zemvelo, iigridi zabo zamandla zihlala zilahlekelwa amandla ngenxa yeentlekele zemvelo, ngoko kubaluleke kakhulu ukugcina ikhaya lakho Kwiindawo ezihlala zihlaselwa ziintlekele zendalo, iigridi zabo zamandla zihlala zilahlekelwa amandla ngenxa yeentlekele zemvelo. , ngoko ke kubaluleke kakhulu ukugcina izixhobo zakho zasekhaya zisebenza ngexesha lokuphela kombane, ngoko ke iinkqubo zebhetri zelanga zasekhaya zinokuba luncedo kakhulu kwiimeko ezinjalo. Xa usebenza kwimowudi yamandla egcina amandla, inkqubo iya kukhupha kuphela kwisixokelelwano sebhetri yelanga yasekhaya xa kukho ukucima kombane. Ngokomzekelo, ukuba i-SOC yokugcina i-80%, i-lithium ibhetri yebhanki akufanele idlule i-80%. Nokuba kusetyenziso lwabucala kushishino, amashishini kunye namakhaya, izakhono zeESS ibhetrizibonelela ngeenzuzo ezinkulu kunokubonelela nje ngamandla xa kukho ukungaphumeleli kwenethiwekhi. Nangona kusetyenziswa ngasese kwishishini, amashishini kunye namakhaya, amandla ebhetri ye-ESS anika inzuzo enkulu kunokubonelela nje ngamandla xa kukho ukungaphumeleli kwenethiwekhi. Owona mahluko ubalaseleyo apha kukuba, xa kuthelekiswa nezixhobo zamandla ezingxamisekileyo zedizili, ibhanki yelanga ibhetri ye-lithium enikwe amandla ogcino lwamandla Omnye weyona ntlukwano ibalaseleyo apha kukuba, xa kuthelekiswa nezixhobo zamandla ezingxamisekileyo zedizili, ibhanki yelanga yebhetri ye-lithium enikwe amandla okugcina amandla. Iisistim zinamandla okuphendula kwangoko ukunqanda ukuphela kombane omncinci, okunokubangela ukuphuma kombane:
- Ukusilela koomatshini beenkampani
- Ukuyeka imigca yemveliso, okukhokelela ekulahlekeni kwemveliso.
- Ilahleko yezoqoqosho
Iinkqubo ze-Off-grid Kukho amazwe kunye nemimandla engathandi umbane ovela kwigridi ngenxa yendawo ekude, nangona banokufaka iipaneli zelanga ukuvelisa amandla, kodwa oku kufutshane kakhulu, xa kungekho mandla elanga, kusafuneka bahlale kuwo. ebumnyameni, ngoko ukusetyenziswa kwebhetri yelanga yendlu kunokwenza izinga labo lokusetyenziswa kwamandla elanga angama-80% okanye ngaphezulu, kunye nejeneretha okanye ezinye izixhobo zokuvelisa umbane, eli nani linokufikelela kwi-100%. Xa usebenza kule modi, i-inverter iya kunika amandla kumthwalo wokulondoloza kwi-PV kunye ne-lithium ibhetri yebhanki, kuxhomekeke kumthombo wamandla okhoyo. Isebenza njani inkqubo yebhetri yeSolar yaseKhaya? Iinkqubo zebhetri zelanga zasekhaya, kubandakanywa iimodyuli zelanga, abalawuli, i-inverters, iibhanki ze-lithium ibhetri, imithwalo, kunye nezinye izixhobo, zineendlela ezininzi zobugcisa. Ngokwendlela amandla adityanisiweyo ngayo, ngoku kukho ii-topology ezimbini eziphambili: "i-DC Coupling" kunye ne "AC Coupling". Ngokusisiseko, iiphaneli zelanga zithatha amandla avela elangeni kwaye la mandla ahlawuliswa kwi-aikhaya lithium ibhetri(enokugcina amandla asuka kwigridi). I-inverter ke inxalenye eguqula amandla abanjwe abe ngumbane ofanelekileyo wokusetyenziswa. Ukusuka apho, umbane usiwa kwipaneli yombane yekhaya. Ukudibanisa kwe-DC:Umbane we-DC ovela kwimodyuli ye-PV ugcinwe kwiipakethi zebhetri zelanga zasekhaya ngokusebenzisa isilawuli, kwaye igridi inokuhlawulisa iipakethi zebhetri yelanga yasekhaya nge-bi-directional DC-AC converter. Indawo yokuhlangana kwamandla ikwisiphelo sebhetri yelanga yeDC. Udibaniso lwe-AC:Amandla e-DC ukusuka kwimodyuli ye-PV itshintshelwe kumandla e-AC ngokusebenzisa i-inverter kwaye yondliwe ngokuthe ngqo kumthwalo okanye kwigridi, kwaye igridi inokuhlawulisa iipakethi zebhetri zelanga zasekhaya nge-bidirectional DC-AC converter. Indawo yokudibanisa amandla ikwisiphelo se-AC. Ukudibanisa kwe-DC kunye nokudibanisa kwe-AC zombini izisombululo ezivuthiweyo, nganye ineenzuzo zayo kunye nokungonakali, ngokuxhomekeke kwisicelo, khetha isisombululo esifanelekileyo. Ngokwendleko, i-DC coupling scheme ixabisa kancinci kune-AC coupling scheme. Ukuba ufuna ukongeza inkqubo yebhetri yelanga kwi-PV esele ifakiwe, kungcono ukusebenzisa i-AC coupling, nje ukuba ibhanki ye-lithium yebhetri kunye ne-bi-directional converter yongezwa, ngaphandle kokuchaphazela inkqubo ye-PV yokuqala. Ukuba yinkqubo esanda kufakwa kunye ne-off-grid, i-PV, i-lithium ibhetri yebhanki, kunye ne-inverter kufuneka iyilwe ngokuhambelana nomthwalo womthwalo womsebenzisi kunye nokusetyenziswa kwamandla, kwaye ifaneleke ngakumbi ukusebenzisa inkqubo yokudibanisa i-DC. Ukuba umsebenzisi unomthwalo omninzi emini nangaphantsi ebusuku, kungcono ukusebenzisa i-AC coupling, imodyuli ye-PV inokubonelela amandla kumthwalo ngokuthe ngqo kwi-inverter edibeneyo yegridi, kwaye ukusebenza kakuhle kunokufikelela ngaphezu kwe-96%. Ukuba umsebenzisi unomthwalo omncinci emini nangaphezulu ebusuku, kwaye amandla e-PV kufuneka agcinwe emini kwaye asetyenziswe ebusuku, ukudibanisa kwe-DC kubhetele, kwaye imodyuli ye-PV igcina amandla kwibhanki yebhetri ye-lithium ngokusebenzisa umlawuli. , kunye nokusebenza kakuhle kunokufikelela ngaphezu kwe-95%. Ngoku ukuba uyazi izibonelelo zeenkqubo zebhetri zelanga zasekhaya kuwe, unokugqiba ukuba isisombululo asivumeli kuphela ukuguqulwa kwamandla kwi-100% yamandla avuselelekayo kodwa nokugcina imali kwiibhilidi zombane kwikhaya, urhwebo okanye ukusetyenziswa kwezoshishino. Iinkqubo zebhetri zelanga zasekhaya ziyisisombululo kule ngxaki. Sondela kwi-BSLBATT, umenzi okhokelayo weiinkqubo zokugcina amandla ebhetri ye-lithium-ioneTshayina.
