Ngaba uceba ukuseta isixokelelwano sogcino lwamandla ekhaya kodwa uzive udityaniswa neenkcukacha zobugcisa? Ukusuka kwii-inverters kunye neeseli zebhetri ukuya kwiibhodi zocingo kunye nokukhusela, icandelo ngalinye lidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kunye nokhuseleko. Masicalule izinto eziphambili ekufuneka siziqwalasele xa ukhetha inkqubo yakho.
Inyathelo 1: Qala nge-Inverter
I-inverter yintliziyo yesixokelelwano sakho sogcino lwamandla, iguqula amandla eDC ukusuka kwiibhetri ukuya kumandla e-AC kusetyenziso lwasekhaya. Yaloukukala amandlaichaphazela ngokuthe ngqo ukusebenza kunye neendleko. Ukumisela ubungakanani obufanelekileyo, bala yakhoincopho yemfuno yamandla.
Umzekelo:
Ukuba usetyenziso lwakho oluphezulu lubandakanya i-2000W yokupheka yokungenisa kunye ne-800W yeketile yombane, amandla ewonke afunekayo yi-2800W. Ubalo-mali lokugqithisa okunokubakho kwiinkcukacha zemveliso, khetha i-inverter okungenani3kW amandla(okanye ngaphezulu kumda wokhuseleko).
IMiba yoNgeniso lweVoltage:
Ii-inverters zisebenza kumbane othile (umzekelo, i-12V, i-24V, i-48V), elawula amandla ombane ebhanki yakho. Amandla ombane aphezulu (afana ne-48V) anciphisa ukulahlekelwa kwamandla ngexesha lokuguqulwa, ukuphucula ukusebenza kakuhle. Khetha ngokusekelwe kwisikali senkqubo yakho kunye nohlahlo lwabiwo-mali.
Inyathelo 2: Bala IiMfuno zeBhanki yeBattery
Nje ukuba i-inverter ikhethiwe, yila ibhanki yakho yebhetri. Kwinkqubo ye-48V, iibhetri ze-lithium iron phosphate (LiFePO4) zithandwa kakhulu ngenxa yokhuseleko kunye nokuphila ixesha elide. Ibhetri ye-48V LiFePO4 ibandakanyaIiseli ezili-16 kuthotho(3.2V ngeseli nganye).
Ifomula engundoqo yokulinganisa kwangoku:
Ukuze ugweme ukushisa, balaubuninzi bokusebenza okwangokuusebenzisa iindlela ezimbini:
1.Ubalo oluSekwe kwi-Inverter:
Current=Amandla oMguquli (W)Igalelo lamandla ombane (V)×1.2 (imeko yokhuseleko)Current=Umbane woNgeniso (V)Amandla oMguquli (W)×1.2(imeko yokhuseleko)
Kwi-inverter ye-5000W kwi-48V:
500048×1.2≈125A485000×1.2≈125A
2.Ubalo oluSekwe kwiSeli (I-Conservative ngakumbi):
Okwangoku=Amandla oMguquli (W)(Ubalo lweeSeli × Ubuncinci boMbane wokuPhuma)×1.2Yangoku=(UBalo lweSeli × Ubuncinane boMbane wokuPhuma)Amandla oMguquli (W)×1.2
Kwiiseli ezili-16 kwi-2.5V yokukhupha:
5000(16×2.5)×1.2≈150A(16×2.5)5000×1.2≈150A
Ingcebiso:Sebenzisa indlela yesibini kwimida yokhuseleko ephezulu.
Inyathelo lesi-3: Khetha i-Wiring kunye ne-Protection Components
Iintambo kunye neebhasi:
- Iintambo eziphumayo:Kwi-150A yangoku, sebenzisa i-18 sq.mm ucingo lobhedu (olulinganiswe kwi-8A/mm²).
- Ii-Inter-cell Connectors:Khetha i-25 sq.mm ye-copper-aluminium composite busbars (ilinganiswe kwi-6A/mm²).
Ibhodi yoKhuselo (BMS):
Khetha aInkqubo yolawulo lwebhetri elinganiswe yi-150A (BMS). Qinisekisa ukuba iyachazaumthamo wangoku oqhubekayo, hayi incopho yangoku. Ukuseta iibhetri ezininzi, khetha iBMS ngeimisebenzi ehambelanayo yangoku yokunciphisaokanye ukongeza imodyuli ehambelanayo yangaphandle ukulinganisa imithwalo.
Inyathelo 4: Iinkqubo zebhetri ezinxuseneyo
Ugcino lwamandla asekhaya luhlala lufuna iibhanki ezininzi zeebhetri ngokunxuseneyo. Sebenzisaiimodyuli ezingqinelanayo eziqinisekisiweyookanye i-BMS ene-bancing eyakhelwe-ngaphakathi ukuthintela ukutshaja okungalinganiyo/ukukhupha. Kuphephe ukudibanisa iibhetri ezingahambelaniyo ukwandisa ubomi.
Iingcebiso zokugqibela
- Beka izinto ezibalulekileyo kwindawo yokuqalaIiseli ze-LiFePO4kukhuseleko kunye nobomi bomjikelezo.
- Qinisekisa iziqinisekiso (umzekelo, UL, CE) kuwo onke amacandelo.
- Dibana neengcali zofakelo oluntsonkothileyo.
Ngokulungelelanisa i-inverter yakho, ibhanki yebhetri, kunye nezixhobo zokukhusela, uya kwakha inkqubo yogcino lwamandla ethembekileyo nesebenzayo ekhaya. Ukuntywila nzulu, jonga isikhokelo sethu sevidiyo esineenkcukacha malunga nokuseta ibhetri ye-lithium!
