Xaiv ntawm a51.2v 280ahthiab51.2v 300Lub roj teeb li dag zoo li kev txiav txim siab me me - Tab sis nws cuam tshuam rau cov chaw tsim nyog, runtime, txee, thiab nthuav yav tom ntej. Cov lus qhia no muab cov ntsiab lus meej rau koj, cov lej- thawj zaug sib piv yog li koj tuaj yeem xaiv qhov kev xaiv zoo tshaj plaws rau koj lub tsev lossis kev lag luam kev lag luam me me.
1) Ceev Specs & Lej
| Tus qauv | Nominal voltage | Nominal muaj peev xwm | Khaws cia lub zog (KWH) | Cov ntawv raug | Sau ntawv |
|---|---|---|---|---|---|
| 51.2v 280ah | 51.2V | 280AH | 14.36 kWh (51.2×280/1000) | Khib / Phab Ntsa Pob | Feem ntau ua los ntawm 280ah Prismatic hlwb |
| 51.2v 300 | 51.2V | 300ah | 15.360 kwh | Khib / Phab Ntsa Pob | ~ 7.1% muaj zog dua 280ah |
Siv lub zog (muaj tseeb):xav tias 90% dod thiab ~ 92% inverter efficiency → siv tau ≈Nominal kwh × 0.828
- 280AH →≈11.87 KWh siv tau
- 300ah →≈12.72 KWh siv tau
- Uas yog ≈7.1%Ntau lub zog siv tau nrog 300 tawm pob.
2) Runtime: Koj tau txais dab tsi?
| Thauj khoom profile | Piv txwv cov khoom siv | 280ah illable (≈11.87KWHWH) | 300ah usable (≈12.72kWhwh) |
|---|---|---|---|
| 500W puag Load | Teeb + Router + Fridge Cycling | ≈23.7 h | ≈25.4 h |
| 1,000w nruab nrab | Teeb + Fridge + TV / Tus kiv cua | ≈11.9 h | ≈12.7 h |
| 2,000w hnyav | ntxiv microwave / Tso tawm theem sib tshooj | ≈5.9 h | ≈6.4 h |
Yog tias koj lub peev xwm zoo nkauj yog ~ 6-8 kWH, ib pob 280Ah feem ntau yog txaus; Yog tias koj nquag haus 8 - {{{{}} Kå dhau ib hmo (AC, cov twj loj), tus 300 tsis muaj kev nyab xeeb dua.
3) Tus nqi rau ib kwh: ib txoj hauv kev yooj yim los txiav txim siab ntawm tus nqi
- Vim tias 300ah muab+7.1%Zog, nws tsim nyog themmus txog ~ 7%ntau rau tib $ / kWh.
- Yog tias tus nqi 300ah tus nqi hwm< 7%, nws yog tus nqi zoo dua rau kWh.
- Yog tias tus hwm> 7–10%, 280Ah feem ntau yeej ntawm kev lag luam.
Piv txwv li:
- 280Ah ntawm $ 1,600 →$ 111.6 / kWh (1600/14.336)
- 300ah ntawm $ 1,720 (+7.5%) →$ 112.0 / kWh(1720 / 15.36) → ntxug cov nqi sib npaug
4) Inverter Pairing & Coos Chaw (16S LifePo₄)
Ob leeg yog48v {- Chav Kawm (16S)Pob, yog li cov chaw tseem ceeb yog tib yam. Yuav tsum ua raws li koj lub roj teeb datasheet; Raug ntau li:
- Kev nqus cov roj teeb:56.8-58.4 V (Ntau tus xaiv xaiv57.6 VTxhawm rau txuas lub neej)
- Ntab:Tawm lossis qis heev (lifepo₄ tsis xav tau ntab zoo li cov txhuas - acid)
- Qis - voltage txiav - tawm (inverter):≈ 44-46 v (Khaws qee qhov tshwj tseg)
- Them / Tawm Tam Sim No:Teeb los ntawm BMS & Inverter; Dlhos nrog spec (piv txwv li, 80-120A nruam yog ib txwm muaj rau ib pob)
Tswv yim:Nrog siab - Cov twj siv ua kom zoo, tsim kom meej inverter ntxhov siab thiab ntim cov pob khoom tam sim no tuaj yeem npog pib.
5) Txav kom haum, qhov hnyav & xov
- Qhov loj me / Qhov hnyav:300 txog cov koog feem ntau yog me ntsis loj dua / hnyav dua. Paub meej tias Khib chaw qhov tob tob thiab sab kev pom zoo rau cov cable.
- Cables & Kev Tiv Thaiv:Siv tooj liab loj (piv txwv li, 25-35 mm² rau 100-150a khiav), DC breaker / fuse nyob ze lub roj teeb zoo, thiab tid nyob ze busebars yog tias nyob twj ywm.
- Kev tsim qauv cua sov:Cov Khoom Zoo SivE6 - phaj compression + steel - strap qhov kub kho kom kub; Tsis muaj tus kiv cua yuav tsum muaj nyob rau hauv ib txwm muaj cov xwm txheej ambient.
6) Kev sib tw nthuav dav & sib xyaw
Kev xyaum zoo tshaj plaws:Khaws txhua pobTib Tus Qauv / Lub Peev Xwm / Firmware.
Yog kojyuav tsumSib tov 280ah thiab 300ah:
- Sab saum toj -} Kev them nyiaj rau ob qho tib si rau 100%, so 30-60 Min, kom tau pob voltages nyob hauvTsawg dua los yog sib npaug rau 0.1 vua ntej nyiam.
- Fuse txhua pob thiab siv luv luv, sib npaug {{0} ntev cables rau ib lub tsheb npav ib txwm txhawb nqa txawm qhia tau.
- Cia siab tias covCov pob loj los muab me ntsis ntxiv tam sim no; Saib xyuas bms cav tom qab commissioning.
- Rau ntev -} sij hawm kev ntseeg tau, npaj ua kom pom tseeb ntawm ib lub peev xwm.
7) Qhov twg haum koj rooj plaub?
Xaiv 51.2V 280ah Yog Koj:
- Kev khiavTsawg dua los yog sib npaug rau 8 kwhHmo ntuj thauj khoom (lub teeb, fridge, kiv cua, electronics)
- Xav tau tusZoo tshaj $ / kWhthiab npaj yuav ntxiv ib pob thib ob tom qab
- Muaj txee / qhov hnyav txiav txom
Xaiv 51.2v 300Hah yog tias koj:
- Kev khiav8 - {10+ kwhHmo ntuj thauj khoom lossis ntau zaus2 kwkos duab
- Xav tauLub taub hau ntxivRau huab huab thiab npog rov qab hosponomy
- Xum cov voj voog tsawg dua ntawm cov dod high dod kom ua tiav lub neej
8) ob {- pob tshuab (rau cov ntsiab lus)
| Pob | 280ah System | 300 lij | Leej twg yog rau |
|---|---|---|---|
| 2 × hauv parallel | 28.67 k yuav nominal(~ 23.7 KWh siv tau) | 30.72 KWHT NOMAL(~ 25.4 KWH siv tau) | Tag nrho -} backup, me b & bs |
| 3 × hauv parallel | 43.01 k yuav nominal | 46.08 kw nominal | Cov nroog loj dua, kev lag luam me me |
