M'mayankho amakono amagetsi, ma solar off-grid system akukhala chisankho kwa mabanja ndi mabizinesi ochulukirachulukira, kupatsa ogwiritsa ntchito ufulu wathunthu wamagetsi ndikuwamasula ku malire ndi kusinthasintha kwa gridi ya anthu. Batire imagwira ntchito ngati phata lofunikira lomwe limagwira ntchito mosasunthika pomwe limapereka magetsi osasokoneza.
Nkhaniyi idzaterokambirananizofunika luso magawo amabatire opanda gridndikufotokozera chifukwa chake mayunitsi a LiFePO4 akuyimira mabatire abwino kwambiri amagetsi oyendera dzuwa.
Zizindikiro Zofunikira za Mabatire a Solar Opanda Grid
Posankha batire lopanda gridi, sikokwanira kuyang'ana gawo limodzi. Kuwunika kokwanira kwa ma metric ofunikira awa kuyenera kuchitidwa.
1.Chitetezo
Chitetezo ndicho chofunikira kwambiri. Mabatire a dzuwa a LiFePO4 amadziwika chifukwa cha kukhazikika kwawo kwapadera komanso kukhazikika kwamankhwala, kuthamangitsa kuthawa kwawoko kuposa ambiri.lithiamu-ionzitsanzo.
Ndi kutentha kwapamwamba kwambiri kwa kutentha kumayambira - nthawi zambiri pafupifupi 250°C poyerekeza ndi pafupifupi150-200 °C paNCM ndi NCAmabatire—amapereka kukana kokulirapo kwa kutenthedwa ndi kuyaka. Khola lawoolivinikapangidwe kake kamalepheretsa kutulutsa mpweya ngakhale kutentha kwambiri, kumachepetsanso chiopsezo cha moto kapena kuphulika. Kuphatikiza apo, mabatire a LiFePO₄ amasunga umphumphu panthawi yamalipiro ndi kutulutsa—palibe kusintha kwapangidwe pansi pa 400℃-kuwonetsetsa kudalirika kwanthawi yayitali komanso mtendere wamumtima m'malo ovuta. Kuphatikiza apo, omanga mapaketi amatha kutsimikizira ndi IEC 62619 ndi UL 9540A kuti akhale ndi kufalitsa.
2.Kutaya Kwambiri Kutulutsa(DoD）
Ponena za DoD, mabatire a dzuwa a LiFePO4 amawonetsa ubwino woonekeratu, womwe ungathe kukwaniritsa DoD yokhazikika ya 80% -95% popanda kuvulaza. DoD ya mabatire a lead-acid nthawi zambiri amangokhala 50% kuti apewe kuwonongeka kwa mphamvu kosatha chifukwa cha sulfation ya mbale.
Chifukwa chake, 10kWhdongosolo yosungirako mphamvupogwiritsa ntchito teknoloji ya LiFePO4 ikhoza kupereka 8-9.5kWh ya mphamvu yogwiritsira ntchito, pamene dongosolo la asidi-lead lingapereke pafupifupi 5kWh.
3.Kutalika kwa Moyo ndi Kutha Kwa Ma Cycle
Mtengo wa ukadaulo wa LiFePO4 udzabweretsa phindu kudzera mu nthawi yayitali yazinthu. Omwe ali ndi asidi otsogolera nthawi zambiri amakhala ndi kuchepa kofulumira kwa magwiridwe antchito pambuyo pa mizungu 300-500 yokha yogwiritsa ntchito kwambiri.
Koma mabatire a LiFePO4 amapereka moyo wozungulira kwambiri wopitilira 6,000 (pa 80% DoD). Ngakhale ndi kuzungulira kutulutsa kamodzi patsiku, amatha kugwira ntchito mokhazikikampaka15 zaka.
4.Kuchuluka kwa Mphamvu
Kuchuluka kwa mphamvu dinendi kuchuluka kwa mphamvu zomwe batire lingasunge pa voliyumu kapena kulemera kwake. Kuchulukana kwamphamvu kwa mabatire a dzuwa a LiFePO4 ndikokwera kwambiri. Kwa mphamvu yofanana, ali ndi kukula kochepa komanso kulemera kwake, kupulumutsadi malo osungiramo komanso kuphweka mayendedwe.
5.Kulipira Mwachangu
Kuyenda bwino kwa batire ya solar ya LiFePO4 ndi 92-97%. Mabatire a acid-lead sachita bwino kwambiri, ndipo maulendo obwerera ndi 70-85%. Pa 10 kWh iliyonse ya mphamvu ya dzuwa yomwe yagwidwa, makina a asidi a lead amasintha 15-25% ya mphamvu ya dzuwa kukhala zinyalala za kutentha. Ndipo kutayika kwa batri ya LFP ndi 0.3-0.8 kWh yokha.
6.Zofunika Kusamalira
Fkapena mabatire osefukira a lead-acid, kukonza chimakwirirakuwunika pafupipafupi kwa milingo ya electrolyte komanso kupewa dzimbiri.
Mabatire a dzuwa a LiFePO4 ndiwopanda kukonza, zomwe sizifunaakusungirako madzi kapena kuyeretsa ma terminal, kapena kukonza ndalama zofananira.
7.Mtengo Woyamba motsutsana ndi Mtengo wa Lifecycle
Mtengo wakutsogolo wa mabatire a LiFePO4 ndiwokweradi. The LiFePO4 off-grid PV system ikuwonetsa mtengo wokwanira wa umwini. Iwo akhozasungani moyo wautali wogwirira ntchito ndipo zimafunikira kusamalidwa pang'ono pamene mukupeza mphamvu zowonjezera mphamvu. Zotsatira zanthawi yayitali zamabizinesiwa zimapangitsa kuti pakhale mtengo wokwera kwambiri.
8.Wide Temperature Range
Mabatire a lead-acid amawonongeka akamagwira ntchito kumalo ozizira. Mabatire a dzuwa a LiFePO4 ali ndi kutentha kwakukulu kogwiritsa ntchitokuchokera-20 ° C mpaka 60 ° C.
9 .Ubwenzi Wachilengedwe ndi Kukhazikika
Mabatire a dzuwa a LiFePO4 amaphatikizanso zitsulo zolemera ngati lead, zomwendi zowopsa kwachilengedwe ndipo amafuna njira zapadera ndi zovuta zobwezeretsanso. Electrolyte yomwe imagwiritsidwa ntchito m'mabatire a lead-acid ndi sulfuric acid, yomwe imawononga ndipo imatha kupsa kwambiri. Kutayikira kapena kutayikira kumatha kupangitsa nthaka ndi madzi kukhala acidic, kuwononga zomera ndi zamoyo zam'madzi.
Ndi Mabatire angati a LiFePO4 a Solar omwe Mukufuna
Kuzindikira kuchuluka kwa batri ndi gawo lofunikira kwambiri pakupanga makina oyendera dzuwa. Tiyeni tidutse chitsanzo kuti tiwone momwe zimachitikira:
(1) Zongoganizira:
l Kugwiritsa Ntchito Mphamvu Patsiku: 5 kWh
l Masiku a Kudzilamulira: 2 masiku
l Battery Yogwiritsidwa Ntchito DoD: 90% (0.9)
l Mphamvu Yadongosolo: 95% (0.95)
l Mphamvu yamagetsi: 48V
l Batri Limodzi Lasankhidwa: 5.12 kWh ROYPOW LiFePO4 Batiri la Solar
(2) Ndondomeko Yowerengera:
l Chofunikira Chosungira Zonse = 5 kWh/tsiku × 2 masiku = 10 kWh
l Kuchuluka Kwa Battery Bank = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Chiwerengero cha Mabatire = 11.7 kWh÷ 5.12 kWh = 2.28 mabatire
Kutsiliza: Popeza mabatire sangagulidwe payekhapayekha, muyenera 3 mwa mabatirewa, omwe amaperekanso malire achitetezo ochulukirapo kuposa zomwe mumafunikira 10 kWh.
Mfundo Zina Posankha LiFeO4 Solar Battery
üKugwirizana Kwadongosolo:Fananizani mphamvu ya batri yakunja kwa gridi ndi inverter / charger yanu, ndikugwiritsa ntchito chowongolera chokhala ndi mbiri ya LFP. Osalipira pansi pa 0 °C, komanso yang'anani kuchuluka kwa batire ndikutulutsa komwe kumayenderana ndi kukula kwa inverter yanu.
üFuture Scalability ndi Modular Design:Konzani kuwonjezera mphamvu ndi ma module ofanana. Waya kudzera pa mabasi kuti chingwe chilichonse chiwone kutalika kwa njira yomweyo, ndikufananiza ma voltages musanafanane kuti mupewe kusalingana. Tsatirani mndandanda wa opanga ndi malire ofanana.
üBrand ndi chitsimikizo:Muyenera kufunafuna mawu osavuta, monga zaka zophimbidwa, malire amagetsi / mphamvu zodutsa, komanso mphamvu yomaliza ya chitsimikizo. Kupitilira apo, ma brand omwe ali ndi ziphaso zachitetezo (IEC 62619 ndi UL 1973) ndi chithandizo chapanthawi yake ayenera kukondedwa.
ROYPOW Mabatire a Lithium-iron Solar
Mabatire athu a ROYPOW lithiamu-iron solar amapereka moyo wautali komanso zosankha zosinthika, ndikuchepetsa ndalama zogwirira ntchito., omwe ndi mayankho abwino a rmakabati a emotetoma solar a off-grid a nyumba. Tengani wathu11.7kWh Battery Yopangidwa Pakhomamwachitsanzo:
- Imayendera ma cell a Grade A LiFePO4, ndikuwonetsetsa kuti ikugwira ntchito bwino ndi magwiridwe antchito apamwamba.
- Zokhala ndi zozungulira zopitilira 6,000, zimasunga magwiridwe antchito odalirika kwa zaka khumi.
- Batire imalola ogwiritsa ntchito kulumikiza mpaka mayunitsi a 16 molumikizana kuti azitha kutulutsa mphamvu.
- It's yogwirizana ndi ma inverter otsogola kuti awonetsetse kuti ali ndi mwayi wothandizira mphamvu.
- Imathandizira kasinthidwe ka adilesi ya DIP yodziwikiratu kuti isinthe kukhazikitsidwa.
- Batire imathandizira kuwunika kwakutali komanso kukweza kwa OTA kudzera pa ROYPOW App.
- Kuthandizidwa ndi zaka 10 za chitsimikizo cha mtendere wamalingaliro.
Kuti tigwirizane ndi malo osiyanasiyana oyika ndi zofunikira zamagetsi, timaperekanso5kWh yokhala ndi khoma, 16kWhchoyimirira pansi,ndi5kw pamabatire a solar okwera pamakina anu opanda gridi.
Okonzekaachiwetrueenergyikudziyimira pawokha ndi ROYPOW? Lumikizanani ndi akatswiri athu kuti mulumikizane naye.
