Hauv cov kev daws teeb meem niaj hnub no, lub hnub ci off-grid systems tau dhau los ua qhov kev xaiv rau ntau tsev neeg thiab kev lag luam, muab cov neeg siv ua tiav lub zog muaj zog thiab tso lawv tawm ntawm cov kev txwv thiab kev hloov pauv ntawm cov phiaj xwm pej xeem. Lub roj teeb ua haujlwm raws li lub hauv paus tseem ceeb uas ua haujlwm ruaj khov thaum muab lub zog tsis muaj kev cuam tshuam.
Kab lus no yuavsib thamqhov tseem ceeb technical parameters ntawmcov roj teeb tsis-gridthiab piav qhia vim li cas LiFePO4 units tam sim no sawv cev rau cov roj teeb zoo tshaj plaws rau lub hnub ci off-grid.
Qhov taw qhia ua haujlwm tseem ceeb ntawm Off-Grid Solar Batteries
Thaum xaiv lub roj teeb off-grid, nws tsis txaus los saib ntawm ib qho kev ntsuas. Yuav tsum ua kom tiav qhov kev ntsuam xyuas ntawm cov kev ntsuas tseem ceeb no.
1.Kev nyab xeeb
Kev nyab xeeb yog thawj qhov kev txiav txim siab. LiFePO4 roj teeb hnub ci muaj npe nrov rau lawv qhov tshwj xeeb thermal thiab tshuaj lom neeg ruaj khov, tiv thaiv thermal runaway zoo dua li feem ntaulithium-ionqauv.
Nrog rau ntau dua thermal runaway pib kub - feem ntau nyob ib ncig ntawm 250°C piv rau txog150–200 ° C rauNCM and NCAroj teeb-lawv muaj kev tiv thaiv ntau dua rau overheating thiab combustion. Lawv ruaj khovolivineqauv tiv thaiv cov pa tawm txawm tias nyob rau hauv qhov kub thiab txias, ntxiv txo qhov kev pheej hmoo ntawm hluav taws kub los yog tawg. Tsis tas li ntawd, LiFePO₄ roj teeb tswj kev ruaj ntseg thaum lub sij hawm them nqi thiab tawm mus-tsis muaj kev hloov pauv hauv qab 400℃- kom ntseeg tau ntev ntev thiab kev thaj yeeb ntawm lub siab nyob rau hauv kev xav tau ib puag ncig. Tsis tas li ntawd, cov neeg tsim khoom ntim tuaj yeem lees paub nrog IEC 62619 thiab UL 9540A kom muaj kev nthuav dav.
2.Sib Nqus Discharge Capacity(DoD)
Nyob rau hauv cov nqe lus ntawm DoD, LiFePO4 roj teeb hnub ci qhia pom qhov zoo dua, uas tuaj yeem ua tiav DoD ruaj khov ntawm 80% -95% yam tsis muaj teeb meem. Lub DoD ntawm cov roj ntsha lead-acid feem ntau yog txwv rau 50% txhawm rau tiv thaiv lub peev xwm mus tas li vim yog phaj sulfation.
Yog li ntawd, 10 kWhzog cia systemsiv LiFePO4 thev naus laus zis tuaj yeem muab 8-9.5kWh ntawm lub zog siv tau, thaum lub tshuab ua kua qaub tsuas tuaj yeem muab kwv yees li 5kWh.
3.Lifespan thiab Cycle Capacity
Tus nqi ntawm LiFePO4 thev naus laus zis kev nqis peev yuav tsim cov khoom xa rov qab los ntawm cov khoom lag luam txuas ntxiv. Cov hmoov lead-acid feem ntau muaj kev poob qis hauv kev ua haujlwm tom qab tsuas yog 300-500 lub voj voog ntawm kev siv hnyav.
Tab sis LiFePO4 roj teeb muaj lub neej sib sib zog nqus tshaj 6,000 cycles (ntawm ntau dua 80% DoD). Txawm tias muaj ib lub voj voog them nqi ib hnub, lawv tuaj yeem ua haujlwm ruaj khov raumus txog15 xyoo.
4.Zog Ceev
Zog ceev dua efines lub zog npaum li cas lub roj teeb tuaj yeem khaws cia rau lub ntim lossis qhov hnyav. Lub zog ceev ntawm LiFePO4 roj teeb hnub ci yog ntau dua. Rau tib lub peev xwm, lawv muaj qhov me me thiab hnyav dua, txuag qhov chaw nruab thiab yooj yim rau kev thauj mus los.
5.Charge Efficiency
Kev ua haujlwm ib puag ncig ntawm LiFePO4 hnub ci roj teeb yog 92-97%. Cov roj ntsha lead-acid tsis tshua muaj txiaj ntsig, nrog rau kev mus ncig ua haujlwm ncig ntawm 70-85%. Rau txhua 10 kWh ntawm lub hnub ci zog ntes, txhuas-acid systems tig 15-25% ntawm lub hnub ci zog rau hauv tshav kub khib nyiab. Thiab qhov poob ntawm LFP roj teeb tsuas yog 0.3-0.8 kWh.
6.Kev Kho Kom Zoo
Flos yog dej nyab lead-acid roj teeb, kev saib xyuas npog covLub sijhawm kuaj xyuas ntawm cov qib electrolyte thiab kev tiv thaiv corrosion ntawm lub davhlau ya nyob twg.
LiFePO4 roj teeb hnub ci yog tsis muaj txij nkawm tiag tiag, uas tsis tas yuav tsum muajateem caij muab dej los yog lub davhlau ya nyob twg tu, los yog vaj huam sib luag nqi tu.
7.Tus nqi pib vs. Tus nqi Lifecycle
Tus nqi ua ntej ntawm LiFePO4 roj teeb yog qhov tseeb dua. The LiFePO4 off-grid PV system qhia tau zoo dua tag nrho cov nqi ntawm cov tswv cuab. Lawv ua tautuav lub neej ua haujlwm ntev dua thiab yuav tsum tau saib xyuas tsawg kawg nkaus thaum ua tiav kev ua haujlwm siab tshaj plaws. Cov txiaj ntsig mus sij hawm ntev ntawm cov kev nqis peev no ua rau muaj kev xa khoom ntau dua.
8.Kev kub siab dav
Lead-acid roj teeb muaj kev ua haujlwm tsis zoo thaum lawv khiav hauv qhov chaw txias txias. LiFePO4 roj teeb hnub ci muaj qhov dav dav ua haujlwm kub ntaulos ntawm-20 ° C txog 60 ° C.
9.Environmental Friendliness thiab Sustainability
LiFePO4 roj teeb hnub ci suav nrog tsis muaj hlau hnyav xws li txhuas, uasmuaj teeb meem rau covib puag ncig thiab yuav tsum tau tshwj xeeb thiab cov txheej txheem rov ua dua tshiab. Cov electrolyte siv nyob rau hauv cov roj teeb lead-acid yog sulfuric acid, uas yog corrosive thiab tuaj yeem ua rau kub hnyiab heev. Kev nchuav los yog xau tuaj yeem ua rau cov av thiab dej, ua rau cov nroj tsuag thiab cov dej nyob hauv dej.
Koj xav tau pes tsawg LiFePO4 roj teeb hnub ci
Kev txiav txim siab lub peev xwm roj teeb yog ib kauj ruam tseem ceeb hauv kev tsim tawm lub hnub ci hluav taws xob. Cia peb taug kev los ntawm ib qho piv txwv kom pom tias nws ua li cas:
(1) Kev xav:
l Kev Siv Zog Txhua Hnub: 5 kWh
l Hnub ntawm Autonomy: 2 hnub
l Roj teeb siv tau DoD: 90% (0.9)
l Kev Ua Haujlwm Zoo: 95% (0.95)
l Qhov System Voltage: 48V
l Ib Leeg Roj Teeb Xaiv: 5.12 kWh ROYPOW LiFePO4 Hnub Ci Roj Teeb
(2) Txheej txheem suav:
l Tag Nrho Kev Cia Siab = 5 kWh / hnub × 2 hnub = 10 kWh
l Total Battery Bank Peev Xwm = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
l Cov roj teeb = 11.7 kWh÷ 5.12 kWh = 2.28 batteries
Xaus: Txij li cov roj teeb tsis tuaj yeem yuav ib tus zuj zus, koj xav tau 3 ntawm cov roj teeb no, uas tseem xa cov txiaj ntsig kev nyab xeeb tshaj li qhov koj xav tau 10 kWh thawj zaug.
Lwm yam kev txiav txim siab thaum xaiv LiFeO4 hnub ci roj teeb
uaSystem Compatibility:Sib piv cov roj teeb hluav taws xob off-grid rau koj lub inverter / charger, thiab siv tus maub los nrog LFP tus nqi profile. Tsis txhob them qis dua 0 ° C, nrog rau tshawb xyuas lub roj teeb lub roj teeb max thiab tso tawm tam sim no tawm tsam koj qhov inverter loj.
uaYav Tom Ntej Scalability thiab Modular Design:Npaj kom muaj peev xwm ntxiv nrog cov qauv zoo ib yam. Hlau los ntawm busbars kom txhua txoj hlua pom tib txoj kev ntev, thiab sib npaug voltages ua ntej paralleling kom tsis txhob muaj qhov tsis sib xws. Ua raws li tus tsim cov koob thiab cov kev txwv tsis sib xws.
uaHom thiab Warranty:Koj yuav tsum nrhiav cov ntsiab lus yooj yim, xws li xyoo them, lub voj voog / lub zog dhau los txwv, thiab qhov kawg ntawm qhov muaj peev xwm lav. Tshaj li nws, cov hom lag luam uas muaj ntawv pov thawj kev nyab xeeb (IEC 62619 thiab UL 1973) thiab cov kev pabcuam hauv zos yuav tsum nyiam.
