Mu njira zamakono zogwiritsira ntchito mphamvu, makina ogwiritsira ntchito mphamvu ya dzuwa omwe sali pa gridi yamagetsi akukhala chisankho cha mabanja ndi mabizinesi ambiri, zomwe zimapatsa ogwiritsa ntchito mphamvu zawo zonse ndikuwamasula ku zoletsa ndi kusinthasintha kwa gridi yamagetsi ya anthu onse. Batri imagwira ntchito ngati maziko ofunikira omwe amasunga magwiridwe antchito okhazikika pomwe amapereka magetsi osasokoneza.
Nkhaniyi idzachita izikambirananimagawo ofunikira aukadaulo amabatire opanda gridindipo fotokozani chifukwa chake mayunitsi a LiFePO4 pakadali pano akuyimira mabatire abwino kwambiri a makina a dzuwa omwe sali pa gridi.
Zizindikiro Zofunika Kwambiri za Mabatire a Dzuwa Osakhala pa Gridi
Posankha batire yopanda gridi, sikokwanira kuyang'ana pa parameter imodzi. Kuwunika kwathunthu kwa miyezo yofunikayi kuyenera kuchitidwa.
1.Chitetezo
Chitetezo ndiye chinthu chofunika kwambiri kuganizira. Mabatire a dzuwa a LiFePO4 amadziwika kuti ndi okhazikika kwambiri pa kutentha ndi mankhwala, ndipo amaletsa kutentha kwambiri kuposa ambiri.lithiamu-iyonizitsanzo.
Ndi kutentha kwakukulu koyambira komwe kumatuluka kutentha—nthawi zambiri pafupifupi madigiri 250°C poyerekeza ndi pafupifupi150–200 °C kwaNCM ndi NCAMabatire—amapereka chitetezo chachikulu ku kutentha kwambiri ndi kuyaka.olivineKapangidwe kake kamaletsa kutulutsa mpweya ngakhale kutentha kwambiri, zomwe zimachepetsa chiopsezo cha moto kapena kuphulika. Kuphatikiza apo, mabatire a LiFePO₄ amasunga umphumphu wa kapangidwe kake panthawi yoyatsira ndi kutulutsa—palibe kusintha kwa kapangidwe kake pansi pa 400℃—kutsimikizira kudalirika kwa nthawi yayitali komanso mtendere wamumtima m'malo ovuta. Kuphatikiza apo, opanga mapaketi angavomereze ndi IEC 62619 ndi UL 9540A kuti aletse kufalikira.
2.Kutulutsa Kwambiri Mphamvu()DoD）
Ponena za DoD, mabatire a dzuwa a LiFePO4 ali ndi ubwino woonekeratu, womwe ungapangitse DoD yokhazikika ya 80%-95% popanda kuvulaza. DoD ya mabatire a lead-acid nthawi zambiri imakhala yochepa pa 50% kuti apewe kuwonongeka kosatha chifukwa cha plate sulfation.
Chifukwa chake, a10kWhnjira yosungira mphamvuKugwiritsa ntchito ukadaulo wa LiFePO4 kungapereke mphamvu yogwiritsidwa ntchito ya 8-9.5kWh, pomwe dongosolo la lead-acid lingapereke mphamvu yokwana 5kWh yokha.
3.Moyo ndi Mphamvu ya Kuzungulira
Mtengo wa ndalama zomwe zimagwiritsidwa ntchito paukadaulo wa LiFePO4 udzabweretsa phindu kudzera mu moyo wautali wa chinthucho. Mafuta a lead-acid nthawi zambiri amachepa mofulumira patatha nthawi 300-500 yokha yogwiritsidwa ntchito kwambiri.
Koma mabatire a LiFePO4 amapereka moyo wautali wozungulira wopitilira ma cycle 6,000 (opitilira 80% DoD). Ngakhale ndi cycle imodzi yotulutsa chaji patsiku, amatha kugwira ntchito mokhazikika kwa nthawi yayitali.mpakaZaka 15.
4.Kuchuluka kwa Mphamvu
Kuchuluka kwa mphamvu definiKuchuluka kwa mphamvu zomwe batire ingasunge pa voliyumu kapena kulemera kwina. Mphamvu ya mabatire a dzuwa a LiFePO4 ndi yayikulu kwambiri. Pa mphamvu yomweyi, ali ndi kukula kochepa komanso kulemera kopepuka, zomwe zimasunga malo oyikamo komanso zimapangitsa kuti mayendedwe azikhala osavuta.
5.Kulipiritsa Mwachangu
Mphamvu ya batire ya solar ya LiFePO4 yoyendera ndi 92-97%. Mabatire a lead-acid sagwira ntchito bwino kwenikweni, ndipo mphamvu ya mayendedwe ndi 70-85%. Pa 10 kWh iliyonse ya mphamvu ya dzuwa yomwe yagwidwa, machitidwe a lead-acid amasintha 15-25% ya mphamvu ya dzuwa kukhala zinyalala zotentha. Ndipo kutayika kwa batire ya LFP ndi 0.3-0.8 kWh yokha.
6.Zofunikira pa Kukonza
Fkapena mabatire odzaza ndi asidi ya leadkukonza chimakwiriraKuwunika nthawi ndi nthawi kuchuluka kwa ma electrolyte ndi kupewa dzimbiri.
Mabatire a dzuwa a LiFePO4 ndi opanda kukonza kwenikweni, zomwe sizifunaaKuyeretsa madzi nthawi ndi nthawi kapena malo osungira madzi, kapena kukonza ndalama zolipirira.
7.Mtengo Woyamba vs Mtengo wa Moyo Wonse
Mtengo wa mabatire a LiFePO4 ndi wokwera kwambiri.FePOMakina anayi a PV omwe sali pa gridi yamagetsi akuwonetsa mtengo wabwino kwambiri wa umwini. AngatheZimakhala ndi nthawi yayitali yogwirira ntchito ndipo sizifuna kukonza kwambiri pamene zikugwiritsa ntchito mphamvu moyenera. Zotsatira za nthawi yayitali za ndalamazi zimapangitsa kuti phindu lonse likhale lalikulu.
8.Kutentha Kwambiri
Mabatire a lead-acid amawonongeka akamagwira ntchito pamalo ozizira. Mabatire a solar a LiFePO4 ali ndi kutentha kwakukulu komwe amagwira ntchitokuchokera-20°C mpaka 60°C.
9.Ubwino wa Zachilengedwe ndi Kukhazikika
Mabatire a dzuwa a LiFePO4 alibe zitsulo zolemera monga lead, zomwendizoopsa kwaMalo ozungulira ndipo amafuna njira zapadera komanso zovuta zobwezeretsanso. Electrolyte yomwe imagwiritsidwa ntchito m'mabatire a lead-acid ndi sulfuric acid, yomwe imawononga ndipo ingayambitse kutentha kwambiri. Kutaya kapena kutayikira kumatha kupangitsa nthaka ndi madzi kukhala acid, kuvulaza zomera ndi zamoyo zam'madzi.
Kodi Mukufuna Mabatire Angati a LiFePO4 a Solar
Kudziwa kuchuluka kwa batri ndi gawo lofunika kwambiri pakupanga makina a dzuwa omwe sali pa gridi. Tiyeni tione chitsanzo kuti tiwone momwe zimachitikira:
(1) Malingaliro:
Kugwiritsa Ntchito Mphamvu Tsiku ndi Tsiku: 5 kWh
Masiku Odziyimira Pawokha: Masiku awiri
l Batri Yogwiritsidwa Ntchito DoD: 90% (0.9)
l Kugwira Ntchito Mwadongosolo: 95% (0.95)
l Voltage Yadongosolo: 48V
Batire imodzi yosankhidwa: 5.12 kWh ROYPOW LiFePO4 Batire ya Solar
(2) Njira Yowerengera:
l Zonse Zofunika Kusungirako = 5 kWh/tsiku × Masiku 2 = 10 kWh
l Mphamvu Yonse ya Batri = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Chiwerengero cha Mabatire = 11.7 kWh÷ 5.12 kWh = mabatire 2.28
Pomaliza: Popeza mabatire sangagulidwe paokha, mukufunikira mabatire atatu mwa awa, omwe amaperekanso chitetezo chokwanira kuposa momwe mukufunira poyamba pa 10 kWh.
Zina Zofunika Kuziganizira Posankha Batire ya Solar ya LiFeO4
üKugwirizana kwa Dongosolo:Lumikizani mphamvu ya batri ya off-grid ndi inverter/chaja yanu, ndipo gwiritsani ntchito chowongolera chokhala ndi mbiri ya LFP charge. Musayike chaji pansi pa 0 °C, komanso onani mphamvu yayikulu ya batri ndi kutulutsa mphamvu poyerekeza ndi kukula kwa inverter yanu.
üKukula kwamtsogolo ndi kapangidwe ka modular:Konzani kuwonjezera mphamvu ndi ma module ofanana. Ikani mawaya kudzera mu mabasi kuti chingwe chilichonse chiwone kutalika kwa njira komweko, ndikulinganiza ma voltage musanayike kuti mupewe kusalinganika. Tsatirani mndandanda wa wopanga ndi malire ofanana.
üMtundu ndi Chitsimikizo:Muyenera kufunafuna mawu osavuta, monga zaka zomwe zakhudzidwa, malire a kuzungulira/mphamvu zomwe zimagwiritsidwa ntchito, komanso mphamvu zomwe zimagwiritsidwa ntchito kumapeto kwa chitsimikizo. Kupatula apo, makampani omwe ali ndi ziphaso zachitetezo (IEC 62619 ndi UL 1973) ndi chithandizo chautumiki chapafupi ayenera kukondedwa.
Mabatire a Solar a ROYPOW Lithium-iron
Mabatire athu a ROYPOW lithium-iron amapereka moyo wautali komanso njira zosinthika zopangira, komanso amachepetsa ndalama zogwirira ntchito., zomwe ndi njira zabwino zothetsera rnyumba za emotetomakina a dzuwa omwe sagwiritsidwa ntchito pa gridi yamagetsi a nyumba. Tengani makina athu amagetsi a dzuwaBatire Yokwezedwa Pakhoma ya 11.7kWhmwachitsanzo:
- Imagwira ntchito pa maselo a Giredi A LiFePO4, kutsimikizira kuti imagwira ntchito bwino komanso imagwira ntchito bwino kwambiri.
- Ili ndi ma cycle opitilira 6,000, imasunga magwiridwe antchito odalirika kwa zaka khumi.
- Batri imalola ogwiritsa ntchito kulumikiza mayunitsi 16 nthawi imodzi kuti apereke mphamvu mosavuta.
- It'imagwirizana ndi makampani otsogola a inverter kuti iwonetsetse kuti pali chithandizo champhamvu chopanda vuto.
- Imathandizira kukonza adilesi ya DIP switch yokha kuti isinthe momwe imakhalira.
- Batriyi imathandizira kuyang'anira patali nthawi yeniyeni komanso kukweza kwa OTA kudzera pa ROYPOW App.
- Chitsimikizo cha zaka 10 cha mtendere wamumtima chimathandizidwa ndi chitsimikizo.
