Nrog rau cov nqi hluav taws xob nce thiab hluav taws xob hluav taws xob tau dhau los ua ntau zaus hauv ntau thaj chaw, lub zog cia hauv tsev tau dhau los ua ib qho yuav tsum muaj rau cov tsev neeg niaj hnub no. Lub roj teeb cia hauv tsev tso cai rau cov tswv tsev khaws cov hnub ci zog, txo cov nqi hluav taws xob, thiab tswj lub zog thaub qab thaum daim phiaj tsis ua haujlwm. Tab sis nrog ntau txoj kev xaiv ntawm kev ua lag luam, koj yuav xaiv qhov zoo li cas rau koj lub tsev?
Phau ntawv qhia no piav qhia txog cov ntsiab lus tseem ceeb uas koj yuav tsum xav txog ua ntej yuav khoom lub zog cia hauv tsev, nrog rau cov lus pom zoo raws li cov xwm txheej tiag tiag.
1. Lub Tsev Hluav Taws Xob Cia Hluav Taws Xob yog dab tsi?
Lub tsev cia khoom hluav taws xob hauv tsev (tseem hu ua ESS nyob hauv tsev) yog lub roj teeb rov qab uas khaws hluav taws xob los ntawm lub hnub ci vaj huam sib luag lossis daim phiaj. Nws feem ntau muaj xws li:
Lithium roj teeb pob (5-20 kWh lossis ntau dua)
Hybrid inverter los yog roj teeb inverter
Battery Management System (BMS)
Saib xyuas app lossis kev tswj hwm lub zog
Cov tswv tsev siv cov txheej txheem no kom ua tiav:
Txo cov nqi hluav taws xob txhua hli
Ua kom muaj zog ywj pheej
Thaub qab fais fab thaum tsis muaj zog
Kev siv lub hnub ci zoo dua (kev siv tus kheej-)
2. Koj Yuav Tsum Muaj Peev Xwm Ntau npaum li cas? (5 kWh, 10 kWh lossis 15 kWh?)
Lub peev xwm roj teeb nyob ntawm koj qhov kev siv txhua hnub thiab kev xav tau thaub qab.
Phau Ntawv Qhia Tsev Neeg
| Hom tsev | Pom muaj peev xwm | Haum rau |
|---|---|---|
| Tsev neeg me / Chav tsev | 5-7 kWh | Lub teeb, TV, fridge |
| Lub tsev nruab nrab | 10-15 kWh | Cov khoom siv hauv tsev feem ntau |
| Loj villa | 20-30 kWh | AC + hnyav loads |
Txoj cai ceev:
📌 Kev noj txhua hnub (kWh) × 0.4–0.6 ≈ pom zoo roj teeb loj
(Piv txwv li kev siv hnub ci ib nrab + ib nrab daim phiaj txhawb nqa)
Piv txwv:
Ib lub tsev siv 18 kWh/hnub → 18 × 0.5 ≈9 kWh roj teeb
3. Lifespan & Cycle Life: Vim Li Cas Nws Tseem Ceeb
Feem ntau siab - cov roj teeb zoo hauv tsev siv lithium hlau phosphate (LiFePO₄). Nws muaj:
🔋 6000+ cycleslub neej
🔥 Kev nyab xeeb dua
🌡 ruaj khov nyob rau hauv siab - cheeb tsam kub
📉 Tsawg degradation piv rau NCM roj teeb
Lub kaw lus siv txhua hnub tuaj yeem siv tau yooj yim10-15 xyoo.
4. Koj yuav tsum xaiv lub roj teeb Stackable lossis phab ntsa-Mounted?
Phab ntsa-Mounted Battery
Ntxuav thiab compact
Yooj yim rau cov chav tsev lossis qhov chaw me me
Qhov loj me: 5-10 kWh
Stackable / Modular Roj teeb
Kev nthuav dav (5-30 kWh)
Zoo tagnrho rau villas, ua liaj ua teb, lag luam me
Xaiv phab ntsa-mounted thaum koj xav kom zoo nkauj sab hauv tsev.
Xaiv stackable thaum xav tau kev nthuav dav tom qab.
5. Hybrid lossis AC-Coupled Inverter? Qhov txawv yog dab tsi?
Hybrid Inverter
Hands hnub ci input + roj teeb them
Tso cai rau hnub ci rau lub hwj chim loads thaum muaj hluav taws xob
Qhov zoo tshaj plaws rau kev teeb tsa PV + roj teeb tshiab
AC -Coupled Inverter
Haum rau cov tsev uas twb muaj hnub ci
Yooj yim ntxiv roj teeb yam tsis hloov PV inverter
📌 Hybrid=ua haujlwm zoo dua rau cov tshuab tshiab
📌 AC-coupled=zoo tshaj plaws rau retrofitting tsev uas twb muaj lawm
6. Lub hnub ci ntau npaum li cas rau lub tsev roj teeb?
Nov yog qhov pom zoo ua khub:
| Roj Teeb Muaj Peev Xwm | Pom zoo hnub ci zog |
|---|---|
| 5 kWh | 2-3 kW PV |
| 10 kWh | 4-6 kW PEB |
| 15 kWh | 6-8 kW PEB |
| 20 kWh | 8-10 kW PV |
Lub zog sib npaug ua kom them sai sai thiab ruaj khov thaum hmo ntuj.
7. Cov yam ntxwv ntawm kev nyab xeeb koj yuav tsum tsis txhob tsis quav ntsej
Lub roj teeb zoo hauv tsev yuav tsum muaj xws li:
Tshaj- tiv thaiv hluav taws xob
Luv- tiv thaiv Circuit Court
Tshaj -kub kaw
Cell ntsuas qhov system
Hluav taws kub-cov vaj tsev tsis zoo
Kev saib xyuas chaw taws teeb (WiFi / 4G)
Nrhiav cov ntawv pov thawj xws li:
CE • RoHS • UN38.3 • IEC62133 • MSDS
8. Lub Tsev Cia Lub Tsev Uas Lub Tshuab Cua Txias Hluav Taws Xob puas tuaj yeem ua tau?
Yog-yog tias lub zog inverter txaus.
Siv:
3.5 kW cua txias → xav tau 5-6 kW inverter
Tag nrho -lub tsev thaub qab → 8-12 kW inverter pom zoo
Thaum tsaus ntuj, lub roj teeb 10-15 kWh tuaj yeem txhawb nqa 1-2 lub tshuab cua txias nyob ntawm kev siv.
9. Koj puas xav tau lub zog thaub qab? Off-Grid lossis On-Grid?
Ntawm -Grid + Roj teeb (Ntau tshaj)
Siv hnub ci ua ntej
Khaws lub zog ntxiv
Daim phiaj muaj raws li thaub qab
Ntawm -Grid nrog Backup Mode
Cov khoom tseem ceeb (fridge, network, teeb) nyob twj ywm thaum muaj hluav taws xob
Tawm -Grid
Tsis muaj kab sib txuas kiag li
Yuav tsum muaj hnub ci txaus + roj teeb loj
Haum rau tej thaj chaw deb, Islands tuaj, cabins
Urayzero tuaj yeem muab tag nrho cov qauv tsim raws li koj qhov kev noj txhua hnub thiab cov kab sib chaws hauv zos.
10. Kev teeb tsa qhov chaw: Sab hauv lossis sab nraum zoov?
Cov roj teeb sab nraum zoov yuav tsum muaj:
IP65 waterproof ntsuam xyuas
UV-cov ntaub ntawv tiv thaiv
Dav kub ntau (-20℃rau +55 degree)
Kev teeb tsa sab hauv tsev yuav tsum xyuas kom meej:
Qhov cua
Tsis muaj hnub ci ncaj qha
Nyob deb ntawm cov pa roj lossis tshuaj lom neeg
11. Yuav kwv yees koj li ROI li cas? (Rov qab ntawm Investment)
Ib qhov dej zoo-zoo sib xws hauv tsev feem ntau them rov qab rau hauv3-6 xyoo, nyob ntawm:
Tus nqi hluav taws xob hauv zos
Hnub ci teev
Seb puas muaj pub- nyob rau hauv tariff
Roj teeb loj
Ntau tus neeg siv khoom qhia txog 60–80% txo cov nqi hluav taws xob tom qab txhim kho ESS hauv tsev.
