UYilwa Njani Awona Mandla aGqibeleleyo eBattery eKhaya?

Ngokuphuhliswa kobuchwepheshe obutsha bamandla kunye neengxaki ezikhulayo zokusingqongileyo kwihlabathi jikelele, ukwandisa ukusetyenziswa kwamandla acocekileyo afana namandla elanga kunye namandla omoya kuba ngomnye wemixholo yexesha lethu. Kweli nqaku, siza kugxila kwiindlela zokusetyenziswa kwamandla elanga kwaye sikuxelele indlela yokuyila ngokwesayensi okona kulungileyoamandla backup amandla ekhaya. Iingcamango ezingezizo eziqhelekileyo xa uyila iNkqubo yokuGcina amandla eKhaya 1. Gxila kuphela kumthamo webhetri 2. Ukulungelelaniswa komlinganiselo we-kW/kWh kuzo zonke izicelo (akukho mlinganiselo omiselweyo kuzo zonke iimeko) Ukuze ufezekise injongo yokunciphisa ixabiso eliqhelekileyo lombane (LCOE) kunye nokunyusa ukusetyenziswa kwenkqubo, iinqununu ezimbini ezingundoqo kufuneka ziqwalaselwe xa kuyilwa inkqubo yokugcina amandla ekhaya kwizicelo ezahlukeneyo: inkqubo yePV kunyeinkqubo yokugcina ibhetri yasekhaya. UKUKHETHA OKUCHANEKILEYO KWENKQUBO YE-PV KUNYE NENKQUBO YOKUBEKA IBHETRI YASEKHAYA KUFUNEKA UQAPHELE NGENXA YEZI ngongoma ZILANDELAYO. 1. INqanaba loMbane weSolar Ubunzulu bokukhanya kwelanga bendawo bunempembelelo enkulu ekukhetheni inkqubo yePV. Kwaye ngokwembono yosetyenziso lwamandla, amandla okuvelisa amandla enkqubo yePV kufanele ukuba anele ukugubungela usetyenziso lwamandla lwemihla ngemihla ekhaya. Idatha enxulumene nobukhulu bokukhanya kwelanga kwindawo inokufumaneka kwi-intanethi. 2. Ukusebenza kweNkqubo Ngokuqhelekileyo, inkqubo yokugcina amandla e-PV ilahlekelwe ngamandla malunga ne-12%, ebandakanya ubukhulu becala. ● Ilahleko yempumelelo yokuguqulwa kwe-DC/DC ● Intlawulo yebhetri / ukukhutshwa komjikelo welahleko yokusebenza kakuhle ● Ilahleko yokusebenza kakuhle kwe-DC/AC yokuguqulwa ● Ukutshaja kwe-AC ilahleko yokusebenza kakuhle Kukho neelahleko ezahlukeneyo ezingenakuphepheka ngexesha lokusebenza kwenkqubo, njengelahleko yokudluliselwa, ukulahleka komgca, ilahleko yokulawula, njl. Ngoko ke, xa uyila inkqubo yokugcina amandla e-PV, kufuneka siqinisekise ukuba umthamo webhetri owenziweyo unokuhlangabezana nemfuno yangempela njengoko kangangoko kunokwenzeka. Ukuqwalasela ilahleko yamandla yenkqubo iyonke, elona xabiso lifunekayo lebhetri kufuneka libe Umthamo webhetri ofunekayo = umthamo webhetri oyiliweyo / ukusebenza kakuhle kwenkqubo 3. ISistim yeBattery yeKhaya yeBattery ekhoyo ekhoyo "Umthamo webhetri" kunye "nomthamo okhoyo" kwitheyibhile yepharamitha yebhetri zizibonakaliso ezibalulekileyo zokuyila inkqubo yokugcina amandla ekhaya. Ukuba umthamo okhoyo awuboniswanga kwiiparamitha zebhetri, unokubalwa ngemveliso yobunzulu bebhetri yokukhupha (DOD) kunye nomthamo webhetri.

Xa usebenzisa ibhanki yebhetri ye-lithium kunye ne-inverter yokugcina amandla, kubalulekile ukuba ubeke ingqalelo kubunzulu bokukhutshwa ngaphezu komthamo okhoyo, kuba ubunzulu be-preset yokukhupha abunakufana nobunzulu bokukhutshwa kwebhetri ngokwayo. xa isetyenziswe kunye ne-inverter ethile yokugcina amandla. 4. Ukuhambelana kweParameter Xa uyila ainkqubo yokugcina amandla ekhaya, kubaluleke kakhulu ukuba iiparitha ezifanayo ze-inverter kunye ne-lithium ibhetri yebhanki ihambelana. Ukuba iiparameters azihambelani, inkqubo iya kulandela ixabiso elincinci ukusebenza. Ngokukodwa kwimowudi yamandla elindileyo, umyili kufuneka abale intlawulo yebhetri kunye nesantya sokukhupha kunye nomthamo wombane ngokusekelwe kwixabiso eliphantsi. Umzekelo, ukuba i-inverter eboniswe ngezantsi ihambelana nebhetri, ubuninzi bentlawulo / ukukhutshwa kwangoku kwenkqubo kuya kuba yi-50A.

5. Iimeko zesicelo Iimeko zesicelo nazo ziyingqwalasela ebalulekileyo xa uyila inkqubo yokugcina amandla ekhaya. Kwiimeko ezininzi, ukugcinwa kwamandla okuhlala kungasetyenziselwa ukunyusa izinga lokusebenzisa amandla amatsha kunye nokunciphisa umbane othengwe yigridi, okanye ukugcina umbane oveliswa yi-PV njengenkqubo yokugcina ibhetri yasekhaya. Ixesha-lokusebenzisa Amandla okuxhasa ibhetri ekhaya Ukuzalisa kunye nokuzisebenzisela Imeko nganye inengqiqo yoyilo eyahlukileyo. Kodwa yonke ingqiqo yoyilo nayo isekelwe kwimeko ethile yokusetyenziswa kombane wasekhaya. Ixesha lokuSebenzisa iRhafu Ukuba injongo yamandla okugcina ibhetri yekhaya kukuhlawula imfuno yomthwalo ngexesha leeyure eziphakamileyo ukuphepha amaxabiso ombane aphezulu, la manqaku alandelayo kufuneka aqatshelwe. A. Isicwangciso sokwabelana ngexesha (iincopho neentlambo zamaxabiso ombane) B. Usetyenziso lwamandla ngamaxesha obunzima (kWh) C. Itotali yokusetyenziswa kwamandla emihla ngemihla (kW) Ngokufanelekileyo, umthamo okhoyo webhetri ye-lithium yasekhaya kufuneka ube phezulu kunemfuno yamandla (kWh) ngexesha leeyure eziphakamileyo. Kwaye umthamo wonikezelo lwamandla wenkqubo kufuneka ube phezulu kunokusetyenziswa kombane kwansuku zonke (kW). Amandla ogcino lwebhetri yeKhaya Kwimeko yenkqubo yokugcina ibhetri yasekhaya, iikhaya lithium ibhetriihlawuliswa yinkqubo ye-PV kunye negridi, kwaye ikhutshwe ukuhlangabezana nemfuno yomthwalo ngexesha lokucima kwegridi. Ukuze kuqinisekiswe ukuba unikezelo lombane aluyi kuphazamiseka ngexesha lokucima kombane, kuyimfuneko ukuyila inkqubo efanelekileyo yokugcina amandla ngokuqikelela ixesha lokuhamba kombane kwangaphambili kunye nokuqonda isixa esipheleleyo sombane osetyenziswa ngamakhaya, ngakumbi imfuno yombane. imithwalo ephezulu yamandla. Ukuzalisa kunye nokuZisebenzisa Le meko yesicelo ijolise ekuphuculeni i-self-generation kunye nesantya sokusebenzisa inkqubo ye-PV: xa inkqubo ye-PV ivelisa amandla aneleyo, amandla avelisiweyo aya kunikwa umthwalo kuqala, kwaye ukugqithisa kuya kugcinwa kwibhetri ukuhlangabezana nayo. imfuno yomthwalo ngokukhupha ibhetri xa inkqubo yePV ivelisa amandla angonelanga. Xa uyila inkqubo yokugcina amandla asekhaya kule njongo, inani elipheleleyo lombane elisetyenziswa yindlu yonke imihla lithathelwa ingqalelo ukuze kuqinisekiswe ukuba umbane owenziwe yi-PV unokuhlangabezana nemfuno yombane. Uyilo lweenkqubo zokugcina amandla e-PV zihlala zifuna ukuqwalaselwa kweemeko ezininzi zesicelo ukuhlangabezana neemfuno zombane wekhaya phantsi kweemeko ezahlukeneyo. Ukuba ufuna ukuphonononga iindawo ezineenkcukacha zoyilo lwenkqubo, udinga iingcali zobugcisa okanye abafaki benkqubo ukubonelela ngenkxaso yobugcisa obungakumbi. Ngexesha elifanayo, uqoqosho lweenkqubo zokugcina amandla ekhaya nazo ziyinkxalabo ephambili. Indlela yokufumana imbuyekezo ephezulu kutyalo-mali (ROI) okanye ukuba kukho inkxaso yomgaqo-nkqubo wenkxaso-mali efanayo, ibe nempembelelo enkulu ekukhethweni koyilo lwenkqubo yokugcina amandla e-PV. Okokugqibela, ngokuqwalasela ukukhula okunokwenzeka kwexesha elizayo kwemfuno yombane kunye neziphumo zokuncipha komthamo osebenzayo ngenxa yokubola kobomi behardware, sincoma ukwandisa umthamo wenkqubo xa uyilwa.amandla elilalela ibhetri izisombululo ekhaya.
