Abathengi abaningi bazobuza, "Ngidinga ibhethri elikhulu kangakanani lelanga?"lapho ukhetha okulungileibhethri elikhulu 48Vezindlini zabo ezinkulu. Ezindlini zesimanje, aibhethri elikhulu lelangaebangeni lika-10-20 kWh manje isiyinketho ekahle yokukhulisa amandla okuzimela kanye namandla ayisipele. Intuthuko kubuchwepheshe bebhethri ye-lithium yenze amandla amakhulu, afana no-15 kWh noma 20 kWh, womabili afinyeleleka futhi angabizi kakhulu. Ngezansi, sihlukanisa indlela yokukhetha usayizi ofanele wezidingo zakho.
1. Ibhethri Elikhulu Lasekhaya: Ukuqondanisa Amandla Nezidingo Zamandla
Ikhaya elijwayelekile lase-US lisebenzisa u-25-35 kWh nsuku zonke, futhi ibhethri elikhulu lamaphaneli elanga (10-20 kWh) lingagcina u-30-60% walesi sidingo.
Ngokwesibonelo, aibhange elikhulu lebhethri lelanga (15 kWh)inika amandla okubalulekile njengeziqandisi, izibani, ne-Wi-Fi amahora angu-18-24. Uma umgomo wakho kuwukuzimela ngokwengxenye kwamandla, qala ngesistimu yelanga yebhethri enkulu ekugcineni engezansi (10-12 kWh).
Kubasebenzisi abasindayo noma abanikazi bezimoto zikagesi, kala ufike ku-20 kWh ukuze uhlanganise ukusetshenziswa okuphezulu.
2. Amabhethri Amakhulu Elanga: Ukulinganisa Amandla Ayisipele Nokusimama Kokucisha
Inani lebhethri elikhulu lelanga liyakhuphuka phakathi nokuphela kukagesi. A20 kWh ibhethriingakwazi ukuthwala umthwalo ongu-2,000W (isb., ifriji ye-HVAC+) amahora angu-10 noma umthwalo omncane ongu-500W amahora angu-40+.
Ukumatanisa amabhethri amakhulu elanga namaphaneli kuqinisekisa ukushajwa kwasemini, kunciphisa ukuthembelaibhethri elikhulu lelanga(30+ kWh) ngaphandle uma ungekho kugridi ngokugcwele. Beka kuqala amasekhethi abalulekile (imishini yezokwelapha, izinhlelo zokuphepha) ukuvimbela ukusebenzisa imali ngokweqile kumthamo ongadingekile.
3. Amasistimu Ebhethri Amakhulu Elanga: Ubuchwepheshe, Ukuhambisana, Nokuqinisekisa Ikusasa
Okwesimanjeamabhethri elanga amakhulu e-lithium-ion(isb,Ibhethri lentsha AMANDLA) inikeza ukujula okungu-100% kokukhishwa kanye neminyaka eyi-10+ yokuphila, okwenza amayunithi angu-10-20 kWh asebenze kahle ukutshalwa kwezimali kwesikhathi eside.
Qinisekisa ukuthi usayizi webhethri lakho elikhulu lelanga lihambisana ne-solar yakho: Isistimu engu-8-10 kW ingakwazi ukukhiqiza u-30-40 kWh nsuku zonke, ishaje kalula20 kWh ibhange elikhulu lebhethri lelanga. Ukuze ukwandise ukusebenza kahle, gwema ukuhlanganisa usayizi owedlulele ngale kokukhiqizwa kwakho kwelanga. Ukushaja ngokweqile kunganciphisa ukusebenza kahle.
Isincomo Sokugcina
Ibhethri elikhulu lelanga elingu-10-20 kWh lingabhalansisa ukusetshenziswa kwansuku zonke, izidingo eziyisipele, kanye nezindleko. Qala ngo-15 kWh ezindlini eziningi futhi unwebe ube kumabhethri amakhulu amamojula amaphaneli elanga uma kudingeka.
Amathuluzi afanaI-NREL PVWatts Calculatoringakwazi ukwenza ngcono ukusetha kwakho—asikho isidingo sokufafaza ibhethri elikhulu lelanga ngaphandle uma kudingekile.
