Ezixazululweni zesimanje zamandla kagesi, amasistimu e-solar off-grid aseba yinketho kumakhaya namabhizinisi amaningi, anikeza abasebenzisi ukuzimela okuphelele nokuwakhulula emikhawulweni nasekuguquguqukeni kwegridi yomphakathi. Ibhethri lisebenza njengomongo obalulekile ogcina ukusebenza okuzinzile kuyilapho inikeza ukunikezwa kwamandla okungaphazamiseki.
Lesi sihloko sizokwenzaxoxaimingcele ebalulekile yezobuchwepheshe yeamabhethri angaphandle kwegridifuthi uchaze ukuthi kungani amayunithi e-LiFePO4 okwamanje emelela amabhethri angcono kakhulu amasistimu elanga angekho kugridi.
Izinkomba Zokusebenza Ezibalulekile Zamabhethri Elanga Angekho Kugridi
Uma ukhetha ibhethri elingaphandle kwegridi, akwanele ukubuka ipharamitha eyodwa. Ukuhlolwa okuphelele kwalawa mamethrikhi abalulekile kufanele kwenziwe.
1.Ukuphepha
Ukuphepha kuwukucatshangelwa okuyinhloko. Amabhethri elanga e-LiFePO4 adume ngokuzinza kwawo okukhethekile okushisayo namakhemikhali, axosha ukubaleka okushisayo kangcono kunamaningi.i-lithium-ionamamodeli.
Ngezinga lokushisa eliphakeme kakhulu le-thermal yokuqala - imvamisa ecishe ibe ngu-250°C uma kuqhathaniswa ne-cishe150-200 °C kweI-NCM ne-NCAamabhethri—anikeza ukumelana okukhulu kakhulu nokushisa ngokweqile nokusha. Isitebela saboumnqumoukwakheka kuvimbela ukukhululwa komoyampilo ngisho nangaphansi kwamazinga okushisa aphezulu, kuqhubeke kunciphisa ingozi yomlilo noma ukuqhuma. Ngaphezu kwalokho, amabhethri e-LiFePO₄ agcina ubuqotho besakhiwo ngesikhathi sokushaja nokukhipha imijikelezo—azikho izinguquko zesakhiwo ngaphansi kuka-400℃-ukuqinisekisa ukwethembeka kwesikhathi eside nokuthula kwengqondo ezindaweni ezinzima. Ngaphezu kwalokho, abakhi bamaphakethe bangase baqinisekise nge-IEC 62619 kanye ne-UL 9540A ukuqukatha ukusatshalaliswa.
2.Ikhono Lokukhipha Okujulile(I-DoD）
Ngokwe-DoD, amabhethri elanga e-LiFePO4 abonisa inzuzo esobala, engafinyelela i-DoD ezinzile ye-80% -95% ngaphandle kokulimala. I-DoD yamabhethri e-lead-acid ngokuvamile ilinganiselwe ku-50% ukuvimbela ukuwohloka kwamandla unomphela ngenxa yokucwenga kwamapuleti.
Ngenxa yalokho, i-a10kWhuhlelo lokugcina amandlausebenzisa ubuchwepheshe be-LiFePO4 inganikeza u-8-9.5kWh wamandla asebenzisekayo, kuyilapho isistimu ye-lead-acid inganikeza kuphela cishe u-5kWh.
3.Ubude bempilo kanye Nomthamo Womjikelezo
Izindleko zokutshalwa kwezimali kobuchwepheshe be-LiFePO4 zizoletha imbuyiselo ngokuhamba kwesikhathi eside komkhiqizo. Ama-lead-acid ngokuvamile abhekana nokwehla okusheshayo ekusebenzeni ngemva kwemijikelezo engu-300-500 kuphela yokusetshenziswa kanzima.
Kodwa amabhethri e-LiFePO4 anikeza impilo yomjikelezo ojulile odlula imijikelezo ye-6,000 (ngaphezu kuka-80% DoD). Ngisho nomjikelezo owodwa wokukhipha imali ngosuku, angasebenza ngokuzinzilekuya kuIminyaka engu-15.
4.Ukuminyana kwamandla
Ukuminyana kwamandla defines ukuthi angakanani amandla ibhethri elingawagcina kuvolumu noma isisindo esithile. Ukuminyana kwamandla amabhethri elanga e-LiFePO4 aphezulu kakhulu. Ngomthamo ofanayo, anosayizi omncane nesisindo esilula, okusindisa ngempela indawo yokufaka nokwenza lula izinto zokuhamba.
5.Ukushaja Ngempumelelo
Ukusebenza kahle kokuya nokubuya kwebhethri lelanga le-LiFePO4 ngu-92-97%. Amabhethri e-lead-acid awasebenzi kahle kangako, asebenza kahle ukuya nokubuya azungeze u-70-85%. Kuwo wonke ama-kWh ayi-10 wamandla elanga abanjwa, amasistimu e-lead-acid aguqula u-15-25% wamandla elanga abe imfucuza yokushisa. Futhi ukulahleka kwebhethri ye-LFP kungu-0.3-0.8 kWh kuphela.
6.Izidingo Zokunakekela
Fnoma amabhethri e-lead-acid agcwele amanzi, ukunakekela ihlanganisa iukuhlolwa ngezikhathi ezithile kwamazinga e-electrolyte kanye nokuvimbela ukugqwala kwetheminali.
Amabhethri elanga e-LiFePO4 awakhokhwa ngempela, okungadingiaukuhlinzekwa kwamanzi okuhleliwe noma ukuhlanzwa kwetheminali, noma ukulungiswa kwezindleko zokulinganisa.
7.Izindleko Zokuqala vs. Izindleko Zomjikelezo Wokuphila
Izindleko zangaphambili zamabhethri e-LiFePO4 ziphakeme ngempela. I-LiI-FePOIsistimu ye-PV engaphandle kwegridi engu-4 ibonisa izindleko ezingcono zobunikazi. Bangakwazigcina impilo ende yokusebenza futhi idinga ukunakekelwa okuncane ngenkathi ifinyelela ukusebenza kahle okukhulu kwamandla. Imiphumela yesikhathi eside yalokhu kutshalwa kwezimali iholela ekulethweni kwenani eliphelele.
8.Ibanga Lokushisa Elibanzi
Amabhethri e-lead-acid ahlangabezana nokuwohloka kokusebenza lapho esebenza ezindaweni ezibandayo. Amabhethri elanga e-LiFePO4 anebanga lokushisa elibanzi lokusebenzakusuka-20°C kuya ku-60°C.
9.Ubungane Bemvelo kanye Nokusimama
I-LiFePO4 amabhethri elanga ahlanganisa akukho izinsimbi ezisindayo njengomthofu, okuyintoziyingozi kuimvelo futhi idinga izindlela ezikhethekile neziyinkimbinkimbi zokugaywa kabusha. I-electrolyte esetshenziswa kumabhethri aneasidi yomthofu i-sulfuric acid, egqwala futhi engabangela ukusha okukhulu. Ukuchitheka noma ukuvuza kungenza inhlabathi namanzi yenze i-asidi, kulimaze izitshalo nempilo yasemanzini.
Mangaki Amabhethri eSolar e-LiFePO4 Owadingayo
Ukunquma umthamo webhethri kuyisinyathelo esibalulekile ekwakhiweni kwesistimu yelanga engaphandle kwegridi. Ake sihambe ngesibonelo ukuze sibone ukuthi kwenziwa kanjani:
(1) Okucatshangwayo:
l Ukusetshenziswa Kwamandla Kwansuku zonke: 5 kWh
l Izinsuku Zokuzimela: Izinsuku ezi-2
l I-DoD Esebenzisekayo Ibhethri: 90% (0.9)
l Ukusebenza Kwesistimu: 95% (0.95)
l Amandla kagesi wesistimu: 48V
l Ibhethri Elilodwa Elikhethiwe: 5.12 kWh ROYPOW LiFePO4 Ibhethri Lelanga
(2) Inqubo yokubala:
l Ingqikithi Yesidingo Sokugcina = 5 kWh/ngosuku × izinsuku ezi-2 = 10 kWh
l Ingqikithi Yamandla Ebhange Lebhethri = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Inombolo Yamabhethri = 11.7 kWh÷ 5.12 kWh = 2.28 amabhethri
Isiphetho: Njengoba amabhethri engenakuthengwa ngawodwa, udinga amabhethri angu-3, aphinde alethe imajini yokuphepha evulekile engaphezu kwemfuneko yakho yokuqala engu-10 kWh.
Okunye Ukucatshangelwa Lapho Ukhetha Ibhethri yeSolar LiFeO4
üUkuhambisana Kwesistimu:Qondanisa i-voltage yebhethri engaphandle kwegridi nesishintshi/ishaja yakho, futhi usebenzise isilawuli esinephrofayela yokushaja ye-LFP. Ungashaji ngaphansi kuka-0 °C, futhi hlola ukushajwa okuphezulu kwebhethri bese ukhipha amandla amanje ngosayizi wakho we-inverter.
üI-future Scalability kanye ne-Modular Design:Hlela ukwengeza umthamo ngamamojula afanayo. Intambo ngamabhasi ukuze iyunithi yezinhlamvu ngayinye ibone ubude bendlela efanayo, futhi ilinganise amandla kagesi ngaphambi kokuhambisana ukuze ugweme ukungalingani. Landela uchungechunge lomenzi kanye nemikhawulo ehambisanayo.
üIbhrendi kanye newaranti:Kufanele ufune amagama alula, njengeminyaka ehlanganisiwe, imikhawulo yomjikelezo/yamandla wokuphuma kwamandla, namandla okuphela kwewaranti. Ngale kwalokho, izinhlobo ezinezitifiketi zokuphepha (IEC 62619 ne-UL 1973) nokusekelwa kwesevisi yendawo kufanele kuncanywe.
I-ROYPOW Amabhethri e-Solar Lithium-iron
Amabhethri elanga ethu e-ROYPOW e-lithium-iron anikeza isikhathi eside sokuphila nezinketho zokuklama ezivumelana nezimo, kanye nezindleko zokusebenza ezincishisiwe., okuyizixazululo ezifanele ze-rama-emote cabinstoamasistimu elanga angaphandle kwegridi yezindlu. Thatha wethu11.7kWh Ibhethri Elifakwe Odongeninjengesibonelo:
- Isebenza kumaseli e-LiFePO4 eBanga A, eqinisekisa ukusebenza okuphephile namazinga aphezulu okusebenza.
- Ifaka imijikelezo engaphezu kuka-6,000, igcina ukusebenza okuthembekile iminyaka eyishumi.
- Ibhethri livumela abasebenzisi ukuthi baxhume amayunithi angama-16 ngokuhambisana ukuze anikeze amandla avumelana nezimo.
- It's iyahambisana namabhrendi e-inverter ahamba phambili ukuze kuqinisekiswe umuzwa wokusekelwa wamandla ongenamthungo.
- Isekela ukulungiswa kwekheli lokushintsha kwe-DIP ukuze kuqondiswe ukusetha.
- Ibhethri isekela ukuqapha okukude kwesikhathi sangempela kanye nokuthuthukiswa kwe-OTA ngohlelo lokusebenza lwe-ROYPOW.
- Ixhaswe yiwaranti yeminyaka eyi-10 yokuthula kwengqondo.
Ukuze uzivumelanise kahle nezikhala ezihlukene zokufaka nezidingo zamandla, sinikeza futhi5kWh odongeni, 16kWhukuma phansi,futhi5kwhamabhethri elanga afakwe kwi-rack yesistimu yakho ye-off-grid.
