Kwizisombululo zamandla zanamhlanje, iinkqubo zesolar off-grid ziba lukhetho kumakhaya amaninzi namashishini, ukunika abasebenzisi ukuzimela okupheleleyo kwamandla kunye nokubakhulula kwimida kunye nokuguquguquka kwegridi yoluntu. Ibhetri isebenza njengondoqo ogcina ukusebenza okuzinzileyo ngelixa ubonelela ngobonelelo lwamandla olungaphazanyiswa.
Eli nqaku lizaxoxaiiparamitha eziphambili zobugcisa zeiibhetri ezingaphandle kwegridikwaye uchaze ukuba kutheni iiyunithi ze-LiFePO4 okwangoku zimele ezona bhetri zibalaseleyo kwiinkqubo zelanga ezingaphandle kwegrid.
Izalathisi zokuSebenza eziPhambili zeebhetri zeSola eziNgasetyenziswa kwiGridi
Xa ukhetha ibhetri engaphandle kwegridi, akwanelanga ukujonga iparamitha enye. Uvavanyo olupheleleyo lwezi metrics ezibalulekileyo kufuneka lwenziwe.
1.Ukhuseleko
Ukhuseleko lolona qwalaselo luphambili. Iibhetri zelanga zeLiFePO4 zaziwa ngozinzo lwazo olukhethekileyo lwe-thermal kunye neekhemikhali, zigxotha ukubaleka kwe-thermal ngcono kunoninzi.lithium-ioniimodeli.
Ngobushushu obuphezulu kakhulu bokubaleka kwe-thermal-ngokuqhelekileyo malunga ne-250°C xa kuthelekiswa malunga150-200 °C ngenxaI-NCM kunye neNCAiibhetri-zinika ukuxhathisa okukhulu kakhulu ekutshiseni kunye nokutshisa. Isitali saboumnqumaisakhiwo sithintela ukukhutshwa kwe-oksijini naphantsi kobushushu obuphezulu, ngakumbi ukunciphisa umngcipheko womlilo okanye ukuqhuma. Ukongeza, iibhetri zeLiFePO₄ zigcina ingqibelelo yesakhiwo ngexesha lokutshaja kunye nokukhupha imijikelo—akukho lutshintsho lwesakhiwo ngaphantsi kwe-400℃-ukuqinisekisa ukuthembeka kwexesha elide kunye noxolo lwengqondo kwiindawo ezifunayo. Ngaphaya koko, abakhi bepakethe banokuqinisekisa nge-IEC 62619 kunye ne-UL 9540A ukuqulatha usasazo.
2.Ukukhupha ubunzulu beZakhono(I-DoD）
Ngokubhekiselele kwi-DoD, iibhetri zelanga ze-LiFePO4 zibonisa inzuzo ebonakalayo, enokufikelela kwi-DoD ezinzileyo ye-80% -95% ngaphandle kokulimala. I-DoD yeebhetri ze-lead-asidi idla ngokukhawulelwa kwi-50% ukunqanda ukuthotywa kwamandla okusisigxina ngenxa ye-plate sulfation.
Ngenxa yoko, i-a10kWhinkqubo yokugcina amandlausebenzisa iteknoloji yeLiFePO4 inokubonelela nge-8-9.5kWh yamandla asebenzisekayo, ngelixa inkqubo ye-lead-asidi inokubonelela kuphela malunga ne-5kWh.
3.Ubomi kunye nesakhono soMjikelo
Iindleko zotyalo-mali kubuchwepheshe be-LiFePO4 ziya kuvelisa imbuyekezo ngokusebenzisa ixesha elide lemveliso. I-lead-acid idla ngokuhla ngokukhawuleza ekusebenzeni emva kwemijikelezo ye-300-500 kuphela yokusetyenziswa okunzima.
Kodwa iibhetri ze-LiFePO4 zinika ubomi bomjikelezo obunzulu obudlula imijikelo ye-6,000 (ngaphezulu kwe-80% ye-DoD). Nokuba umjikelo omnye wokukhutshwa kwentlawulo ngosuku, banokusebenza ngokuzinzileyoixhomekeke kuIminyaka eyi-15.
4.Ukuxinana kwamandla
Ukuxinana kwamandla dkakuhles angakanani amandla anokugcinwa yibhetri kumthamo okanye ubunzima obunikiweyo. Ubuninzi bamandla e-LiFePO4 iibhetri zelanga ziphezulu kakhulu. Ngomthamo ofanayo, banobungakanani obuncinci kunye nobunzima obulula, ngokwenene bagcina indawo yokufakela kunye nokwenza lula ukuthutha.
5.Ukutshaja ngokuSebenzayo
Ukusebenza kokubuya nokubuya kwebhetri yelanga ye-LiFePO4 yi-92-97%. Iibhetri ze-lead-asidi zisebenza kancinci kakhulu, kunye nohambo lokuya nokubuya olujikelezayo malunga ne-70-85%. Nge-10 kWh nganye yamandla elanga ebanjwayo, iinkqubo ze-lead-asidi zijika i-15-25% yamandla elanga ibe yinkunkuma yobushushu. Kwaye ukulahleka kwebhetri ye-LFP yi-0.3-0.8 kWh kuphela.
6.IiMfuneko zoLondolozo
Fokanye iibhetri ze-lead-asidi ezizaliswe ngamanzi, ukugcinwa igubungela iukutshekishwa ngamaxesha athile amanqanaba e-electrolyte kunye nothintelo lwe-terminal corrosion.
Iibhetri zelanga zeLiFePO4 azinasondlo ngokwenene, ezingafunekiyoaunikezelo lwamanzi olucwangcisiweyo okanye ukucocwa kwetheminali, okanye ukulungiswa kwentlawulo yokulinganisa.
7.Iindleko zokuqala vs. Iindleko zoBomi
Iindleko zangaphambili zeebhetri zeLiFePO4 ziphezulu ngokwenene. ULiFePOInkqubo ye-PV engaphandle kwegrid e-4 ibonisa ixabiso elingcono lilonke lobunini. Bangagcina ubomi obude bokusebenza kwaye kufuna ukugcinwa okuncinci ngelixa ufezekisa ukusebenza kakuhle kwamandla. Iziphumo zexesha elide zolu tyalo-mali zikhokelela kunikezelo lwexabiso lilonke eliphezulu.
8.Uluhlu olubanzi lobushushu
Iibhetri ze-lead-asidi zifumana ukuthotywa kokusebenza xa zisebenza kwindawo ezibandayo zobushushu. Iibhetri zelanga ze-LiFePO4 zinoluhlu olubanzi lobushushu bokusebenzaukusuka-20°C ukuya kuma-60°C.
9.UBungane kokusiNgqongileyo kunye noZinzo
Iibhetri zelanga zeLiFePO4 zibandakanya akukho zintsimbi ezinzima njengelothe, ezithiziyingozi kwiimo engqongileyo kwaye ifuna iindlela ezikhethekileyo nezinzima zokurisayikilishwa. I-electrolyte esetyenziswa kwiibhetri ezineasidi yelothe yi-asidi ye-sulfuric, edlayo kwaye inokubangela ukutshisa okukhulu. Ukuchitheka okanye ukuvuza kunokwenza umhlaba kunye namanzi ukuba abe neasidi, oko kwenzakalise izityalo kunye nezinto eziphila emanzini.
Zingaphi iibhetri zeSolar zeLiFePO4 ozifunayo
Ukumisela umthamo webhetri linyathelo elibalulekileyo kuyilo lwesixokelelwano selanga esingekho kwigridi. Makhe sihambe ngomzekelo ukuze sibone ukuba kwenziwa njani:
(1) Iingqikelelo:
l Ukusetyenziswa kwaMandla ngeMihla: 5 kWh
l Iintsuku zokuzimela: iintsuku ezi-2
l Ibhetri Enokusetyenziswa I-DoD: 90% (0.9)
l Ukusebenza kweNkqubo: 95% (0.95)
l Umbane weNkqubo: 48V
l Ibhetri enye Ekhethiweyo: 5.12 kWh ROYPOW LiFePO4 Ibhetri yeSolar
(2) Inkqubo yokubala:
l Iyonke iMfuneko yokuGcina = 5 kWh/ngosuku × iintsuku ezi-2 = 10 kWh
l Umthamo weBhanki iyonke = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Inani leebhetri = 11.7 kWh÷ 5.12 kWh = 2.28 iibhetri
Ukuqukumbela: Kuba iibhetri zingenakuthengwa zodwa, udinga ezi-3 zezi bhetri, ezikwanikezela ngomda wokhuseleko olukhulu ngaphaya kwemfuneko yakho yokuqala ye-10 kWh.
Olunye Uqwalaselo Xa ukhetha i-LiFeO4 ibhetri yeSolar
üUkuhambelana kweNkqubo:Tshatisa amandla ombane ebhetri engaphandle kwegridi kwisiguquli/itshaja yakho, kwaye usebenzise isilawuli esineprofayile yentlawulo ye-LFP. Musa ukuhlawulisa ngaphantsi kwe-0 °C, kwaye ujonge ubuninzi bebhetri yentlawulo kunye nokukhupha okwangoku ngokuchasene nesayizi yakho ye-inverter.
üUkwaleka kwekamva kunye noYilo lweModyuli:Cwangcisa ukongeza umthamo kunye neemodyuli ezifanayo. Ucingo ngeebhasi zebhasi ukuze umtya ngamnye ubone ubude bendlela efanayo, kwaye ulinganise amandla ombane phambi kokungqamana ukunqanda ukungalingani. Landela uthotho lomenzi kunye nemida enxuseneyo.
üUphawu kunye neWaranti:Kuya kufuneka ufune amagama alula, anje ngeminyaka egqunyiweyo, umjikelo/imida yokuphuma kwamandla, kunye nomthamo wewaranti yokuphela. Ngaphandle kwayo, iimpawu ezinezatifikethi zokhuseleko (IEC 62619 kunye ne-UL 1973) kunye nenkxaso yenkonzo yendawo kufuneka ikhethwe.
