Kodi mukukonzekera kukhazikitsa makina osungira mphamvu kunyumba koma mukumva kuti mwathedwa nzeru ndi zambiri zaukadaulo? Kuchokera ku ma inverters ndi ma cell a batri kupita ku ma wiring ndi ma board oteteza, gawo lililonse limagwira ntchito yofunika kwambiri pakuwonetsetsa kuti magwiridwe antchito ndi chitetezo. Tiyeni tidutse zinthu zofunika kuziganizira posankha dongosolo lanu.
Gawo 1: Yambani ndi Inverter
Inverter ndiye mtima wamakina anu osungira mphamvu, kutembenuza magetsi a DC kuchokera ku mabatire kupita ku magetsi a AC kuti mugwiritse ntchito kunyumba. Zakemphamvuzimakhudza mwachindunji ntchito ndi mtengo. Kuti mudziwe kukula koyenera, werengerani zanukufunika kwamphamvu kwambiri.
Chitsanzo:
Ngati kugwiritsa ntchito kwanu pachimake kumaphatikizapo chophikira cha 2000W ndi ketulo yamagetsi ya 800W, mphamvu yonse yofunikira ndi 2800W. Kuwerengera za kuchulukitsitsa komwe kungachitike pamatchulidwe azinthu, sankhani inverter ndi osachepera3 kW mphamvu(kapena apamwamba pa malire achitetezo).
Kuyika kwa Voltage Matters:
Ma inverters amagwira ntchito pamagetsi ena (mwachitsanzo, 12V, 24V, 48V), omwe amalamula mphamvu ya banki yanu. Ma voliyumu apamwamba (monga 48V) amachepetsa kutayika kwa mphamvu pakutembenuka, kuwongolera magwiridwe antchito. Sankhani kutengera kukula kwa dongosolo lanu ndi bajeti.
Khwerero 2: werengerani Zofunikira za Banki ya Battery
Inverter ikasankhidwa, pangani banki yanu ya batri. Kwa dongosolo la 48V, mabatire a lithiamu iron phosphate (LiFePO4) ndi chisankho chodziwika bwino chifukwa cha chitetezo chawo komanso moyo wautali. Batire ya 48V LiFePO4 imakhala ndi16 ma cell angapo(3.2V pa selo).
Ndondomeko Yofunika Kwambiri pa Mawerengedwe Amakono:
Pofuna kupewa kutenthedwa, kuwerengerapazipita ntchito panopakugwiritsa ntchito njira ziwiri:
1.Kuwerengera motengera Inverter:
Current=Mphamvu ya Inverter (W)Input Voltage (V)×1.2 (safety factor)Current=Input Voltage (V)Inverter Power (W)×1.2(safety factor)
Kwa 5000W inverter pa 48V:
500048×1.2≈125A485000×1.2≈125A
2.Kuwerengera Motengera Maselo (More Conservative):
Current=Mphamvu ya Inverter (W)(Kuwerengera Maselo × Kuchepa Kwamagetsi Otulutsa)×1.2Current=(Kuwerengera Maselo × Kuchepa Kwamagetsi Otulutsa)Mphamvu ya Inverter (W)×1.2
Kwa ma cell 16 pakutulutsa kwa 2.5V:
5000(16×2.5)×1.2≈150A(16×2.5)5000×1.2≈150A
Malangizo:Gwiritsani ntchito njira yachiwiri yopezera malire apamwamba.
Gawo 3: Sankhani Wiring ndi Chitetezo Zigawo
Zingwe ndi Mabasi:
- Zingwe Zotulutsa:Kwa 150A yapano, gwiritsani ntchito waya wamkuwa 18 sq.mm (yomwe idavotera 8A/mm²).
- Ma Inter-cell Connectors:Sankhani 25 sq.mm copper-aluminium composite busbars (yomwe ili pa 6A/mm²).
Bungwe la Chitetezo (BMS):
Sankhani a150A-ovotera batire dongosolo kasamalidwe (BMS). Onetsetsani kuti ikufotokozamphamvu yapano mosalekeza, osati nsonga yapamwamba. Pakukhazikitsa mabatire ambiri, sankhani BMS yokhala nayontchito zofananira zapanokapena onjezani gawo lakunja lofananira kuti muchepetse katundu.
Khwerero 4: Ma Battery Ofanana
Kusungirako mphamvu kunyumba nthawi zambiri kumafuna mabanki angapo a batri mofanana. Gwiritsani ntchitocertified parallel moduleskapena BMS yokhala ndi kusanja kokhazikika kuti mupewe kuyitanitsa / kutulutsa kosagwirizana. Pewani kulumikiza mabatire osagwirizana kuti mutalikitse moyo.
Malangizo Omaliza
- Ikani patsogoloMaselo a LiFePO4kwa chitetezo ndi moyo wozungulira.
- Tsimikizirani ziphaso (mwachitsanzo, UL, CE) pazigawo zonse.
- Funsani akatswiri pazoyika zovuta.
Mukagwirizanitsa inverter yanu, banki ya batri, ndi zida zachitetezo, mupanga makina odalirika osungira mphamvu kunyumba. Kuti mutsike mozama, onani kalozera wathu watsatanetsatane wamakanema pakukhathamiritsa makhazikitsidwe a batri la lithiamu!
