Ingabe uhlela ukusetha isistimu yokugcina amandla ekhaya kodwa uzizwe ukhungathekile ngemininingwane yobuchwepheshe? Kusukela kuma-inverter namaseli ebhethri kuya kumabhodi ezintambo nawokuvikela, ingxenye ngayinye idlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokuphepha. Ake sihlukanise izici ezibalulekile okufanele uzicabangele lapho ukhetha isistimu yakho.
Isinyathelo 1: Qala nge-Inverter
I-inverter iyinhliziyo yesistimu yakho yokugcina amandla, eguqula amandla e-DC ukusuka kumabhethri ukuya kumandla we-AC ukuze asetshenziswe ekhaya. Yakhoisilinganiso samandlakuthinta ngqo ukusebenza nezindleko. Ukuze unqume usayizi olungile, bala owakhoisidingo esikhulu samandla.
Isibonelo:
Uma ukusebenzisa kwakho okuphezulu kufaka phakathi i-cooktop yokungenisa engu-2000W kanye neketela likagesi elingu-800W, amandla aphelele adingekayo ngu-2800W. Ukubalwa kwezimali okungenzeka kube ukweqisa ekucacisweni komkhiqizo, khetha inverter okungenaniamandla 3kW(noma ngaphezulu kwemajini yokuphepha).
Izinto Zokufaka I-Voltage:
Iziguquli zisebenza ngama-voltage athile (isb, 12V, 24V, 48V), asho amandla ogesi ebhange lakho lebhethri. Ama-voltage aphezulu (afana no-48V) anciphisa ukulahleka kwamandla ngesikhathi sokuguqulwa, athuthukise ukusebenza kahle kukonke. Khetha ngokusekelwe esikalini sakho nesabelomali.
Isinyathelo sesi-2: Bala Izidingo Zebhange Lebhethri
Uma i-inverter isikhethiwe, klama ibhange lakho lebhethri. Ngohlelo lwe-48V, amabhethri e-lithium iron phosphate (LiFePO4) ayisinqumo esidumile ngenxa yokuphepha kwawo nokuphila isikhathi eside. Ibhethri elingu-48V LiFePO4 ngokuvamile liqukethe16 amaseli ochungechungeni(3.2V iseli ngalinye).
Ifomula Eyinhloko Yezilinganiso Zamanje:
Ukuze ugweme ukushisa ngokweqile, balaesiphezulu ukusebenza kwamanjeusebenzisa izindlela ezimbili:
1.Ukubalwa okusekelwe ku-inverter:
Current=Amandla Okuguqula (W)I-Voltage (V)×1.2 (isici sokuphepha)Current=Amandla Okufaka (V)Amandla Okuguqula (W)×1.2(isici sokuphepha)
Nge-inverter engu-5000W ku-48V:
500048×1.2≈125A485000×1.2≈125A
2.Ukubala Okususelwe Kuseli (Okulandela Imithetho Kakhudlwana):
Yamanje=Amandla Aguquguqukayo (W)(Inani Leseli × Ubuncane Bamandla Amandla Okukhipha Kagesi)×1.2Yamanje=(Isibalo Seseli × Isilinganiso Samandla Okukhipha Okuncane)I-Inverter Amandla (W)×1.2
Kumaseli angu-16 ekukhishweni okungu-2.5V:
5000(16×2.5)×1.2≈150A(16×2.5)5000×1.2≈150A
Isincomo:Sebenzisa indlela yesibili ukuthola amamajini okuphepha aphezulu.
Isinyathelo sesi-3: Khetha Izingxenye Zezintambo Nezokuvikela
Amakhebuli namabhasi:
- Amakhebuli Okukhiphayo:Ku-150A yamanje, sebenzisa intambo yethusi engu-18 sq.mm (ilinganiselwe kokuthi 8A/mm²).
- Izixhumi ze-Inter-cell:Khetha amabhasi ayinhlanganisela ye-copper-aluminium engu-25 sq.mm (alinganiselwe kokuthi 6A/mm²).
Ibhodi Lokuvikela (BMS):
Khetha aIsistimu yokuphatha ibhethri elinganiselwe ngo-150A (BMS). Qinisekisa ukuthi iyacacisaumthamo wamanje oqhubekayo, hhayi amandla aphezulu. Ngokusetha amabhethri amaningi, khetha i-BMS ngeimisebenzi yokukhawulela yamanje ehambisanayonoma engeza imojuli ehambisanayo yangaphandle ukuze ulinganise imithwalo.
Isinyathelo sesi-4: Amasistimu Ebhethri Ahambisanayo
Isitoreji samandla sasekhaya ngokuvamile sidinga amabhange amabhethri amaningi ngokuhambisana. Sebenzisaamamojula parallel aqinisekisiwenoma i-BMS enokulinganisa okwakhelwe ngaphakathi ukuze kuvinjelwe ukushaja/ukukhulula okungalingani. Gwema ukuxhuma amabhethri angafani ukuze welule ubude bempilo.
Amathiphu Okugcina
- Beka kuqalaAmaseli e-LiFePO4ukuphepha nokuphila komjikelezo.
- Qinisekisa izitifiketi (isb, UL, CE) zazo zonke izingxenye.
- Xhumana nochwepheshe ngokufaka okuyinkimbinkimbi.
Ngokuqondanisa i-inverter yakho, ibhange lebhethri, nezingxenye zokuvikela, uzokwakha isistimu yokugcina amandla yasekhaya ethembekile, ephumelelayo. Ukuze uthole ukujula okujulile, bheka umhlahlandlela wethu wevidiyo onemininingwane wokuthuthukisa ukusethwa kwebhethri ye-lithium!
