Uma uklama uhlelo lwamandla elanga olungaphandle kwegridi, omunye wemibuzo ebaluleke kakhulu yile:Udinga amandla ebhethri angakanani?Amabhethri adlala indima ebalulekile ezinhlelweni ezingaphandle kwegridi ngoba agcina ugesi okhiqizwa amaphaneli elanga emini futhi ahlinzeka ngamandla ebusuku noma ngesikhathi sezulu esinamafu.
Ukukhetha umthamo webhethri ofanele kuqinisekisa ukuthi uhlelo lwakho lungaletha ugesi othembekile ngaphandle kokuphazamiseka. Uma ibhange lebhethri lincane kakhulu, amandla agciniwe angaphela ngokushesha. Uma likhulu kakhulu, izindleko zesistimu zingase zikhuphuke ngokungadingekile. Lo mhlahlandlela uchaza indlela yokunquma umthamo webhethri ofanele wesistimu yelanga engaphandle kwegridi.
Kungani Ukugcinwa Kwebhethri Kubalulekile Ezinhlelweni Ezingekho Kugridi
Ngokungafani nezinhlelo zelanga ezixhunywe kugridi, izinhlelo ezingaphandle kwegridi zisebenza ngokuzimela ngokuphelele kugridi yokusetshenziswa. Lokhu kusho ukuthi wonke ugesi odingekayo ebusuku noma ngezikhathi zokukhanya kwelanga okuphansi kumele uvele emandleni agciniwe.
Uhlelo olujwayelekile olungaphandle kwegridi luqukethe izingxenye eziningana ezibalulekile:
- Amaphaneli elanga akhiqiza ugesi emini
- I-inverter eguqula ugesi we-DC ube amandla e-AC
- Amabhethri agcina amandla ukuze asetshenziswe kamuva
- Isilawuli sokushaja esilawula ukushaja nokuvikela ibhethri
Amaphaneli elanga akhiqiza amandla uma ukukhanya kwelanga kutholakala, futhi ugesi owengeziwe ugcinwa emabhethri ukuze usetshenziswe kamuva. Amandla agciniwe abe eseguqulwa yi-inverter abe ugesi ongasetshenziswa ezintweni zasekhaya nemishini.
Isinyathelo 1: Bala Ukusetshenziswa Kwakho Kwamandla Kwansuku Zonke
Isinyathelo sokuqala ekunqumeni umthamo webhethri ukubala ukuthi usebenzisa ugesi ongakanani usuku ngalunye. Lokhu kuvame ukukalwa nge-amahora e-kilowatt (kWh).
Isibonelo, indlu encane engasebenzisi ugesi ingasebenzisa ugesi ku:
- Ukukhanyisa
- Amafriji
- Amafeni noma ama-air conditioner
- Ama-TV namakhompyutha
- Amaphampu amanzi noma izinto ezincane zikagesi
Umndeni ojwayelekile ongaphandle kwegridi ungadla5–15 kWh kagesi ngosuku, kuye ngenani lezinto zikagesi kanye nendlela yokuphila.
Uma usuwazi ukuthi usebenzisa malini nsuku zonke, ungalinganisa umthamo webhethri odingekayo ukuze ugcine amandla anele okusetshenziswa ebusuku.
Isinyathelo 2: Nquma ukuthi Zingaki Izinsuku Zokwenza Isipele Ozidingayo
Izinhlelo eziningi ezingaphandle kwegridi zakhiwe ngeisitoreji esiyisipele sezinsuku ezingu-1 kuya kwezingu-3Lokhu kuqinisekisa ukuthi uhlelo lungaqhubeka nokunikeza ugesi ngisho noma ukukhanya kwelanga kulinganiselwe ngenxa yesimo sezulu esinamafu noma imvula.
Ngokwesibonelo:
Ukusetshenziswa kwamandla nsuku zonke:10 kWh
Izinsuku zokugcina:Izinsuku ezi-2
Isitoreji sebhethri siyadingeka:
10 kWh × 2 =Umthamo webhethri ongu-20 kWh
Lokhu kusho ukuthi ibhange lakho lebhethri kufanele likwazi ukugcina yonke indawoAmandla angasetshenziswa angu-20 kWh.
Isinyathelo 3: Cabanga Ngokujula Kokukhishwa Kwebhethri
Akuwona wonke amandla agcinwe ebhethri angasetshenziswa ngokuphephile. Amabhethri anepharamitha ebizwa ngokuthiUkujula Kokukhishwa (DoD), okunquma ukuthi ingakanani yamandla agciniwe angasetshenziswa ngaphandle kokulimaza ibhethri.
Amanani ajwayelekile afaka:
- Amabhethri e-lead-acid: cisheAmandla angasetshenziswa angu-50%
- Amabhethri e-lithium: cisheAmandla angasetshenziswa angu-80–90%
Isibonelo, uma udingaAmandla angasetshenziswa angu-20 kWh, uhlelo lwebhethri le-lead-acid lungadinga nxazonkeUmthamo ophelele ongu-40 kWh, kuyilapho uhlelo lwebhethri le-lithium lungadinga kuphela cishe25 kWh.
Isibonelo Sokulungiselelwa Kwebhethri Kwezinhlelo Ezingekho Kugridi
Osayizi abahlukene besistimu yelanga badinga amandla ahlukene ebhethri. Nazi ezinye izibonelo ezivamile ezisekelwe ekucushweni kwesistimu okuvamile.
Uhlelo Lwelanga Olungekho Kugridi Oluyi-2KW
Uhlelo oluncane olungaphandle kwegridi lungafaka:
- Amaphaneli elanga angu-4 × 400W
- I-inverter engu-2KW
- Amabhethri ejeli angu-4 × 12V 150Ah
Lokhu kulungiselelwa kunikeza cishe5 kWh yesitoreji sebhethri esiphelele, efanelekela amakhaya amancane, amakhabhini, noma izinhlelo zokukhanyisa eziyisisekelo.
Uhlelo Lwelanga Olungekho Kugridi Oluyi-3KW
Uhlelo lwezindlu oluphakathi nendawo lungasebenzisa:
- Amaphaneli elanga angu-5 × 550W
- I-inverter engu-3.5KW
- Amabhethri angu-4 × 12V angu-250Ah
Lokhu kulungiselelwa kunikeza cisheAmandla ebhethri angu-8.4 kWh, okwanele emindenini emincane ephethe izibani, iziqandisi, kanye nezinto zikagesi eziyisisekelo.
Uhlelo Lwelanga Olungekho Kugridi Oluyi-5KW
Uhlelo olukhulu lwasekhaya luvame ukufaka:
- Amaphaneli elanga angu-8 × 550W
- I-inverter engu-5KW
- Ibhange lebhethri le-48V 200Ah
Uhlelo olunjalo lungakhiqiza cishe20 kWh kagesi ngosuku, enesitoreji esanele sokusekela izinto zasekhaya ubusuku bonke.
Izici Ezithonya Amandla Ebhethri
Ezinye izinto eziningana zingathinta ukuthi uhlelo lwakho lwebhethri kufanele lube lukhulu kangakanani.
Amaphethini Okusetshenziswa Kwamandla
Izindlu ezisebenzisa amandla amaningi, njengeziphephetha-moya noma amaphampu amanzi, zidinga amabhethri amakhulu.
Izimo Zezulu
Izifunda ezinesimo sezulu esinamafu esivame ukuba khona zingadinga indawo yokugcina izinto ukuze kuqinisekiswe ukuthi amandla athembekile.
I-Voltage Yesistimu
Izinhlelo ezingaphandle kwegridi zivame ukusebenzisaAmabhange ebhethri angu-24V noma angu-48V, okuthuthukisa ukusebenza kahle kwesistimu ekufakweni okukhulu.
Ukwanda Kwesikhathi Esizayo
Abanye abasebenzisi bafaka umthamo webhethri omkhulu kancane ukuze uhlelo lukwazi ukusekela izinto ezengeziwe kamuva.
Ukukhetha Uhlobo Lwebhethri Olufanele
Kunezindlela eziningana zobuchwepheshe bebhethri ezisetshenziswa ezinhlelweni zelanga ezingaphandle kwegridi:
Amabhethri e-Lead-Acid
- Izindleko eziphansi kusengaphambili
- Isikhathi sokuphila esifushane
- Kudinga ukulungiswa njalo
Amabhethri e-Gel
- Akukho ukulungiswa
- Ukuthembeka okuhle kwezinhlelo ezingaphandle kwegridi
Amabhethri e-Lithium
- Ukusebenza kahle okuphezulu
- Isikhathi eside sokuphila
- Ukutshalwa kwezimali kokuqala okuphezulu
Amabhethri e-lithium aya ngokuya ethandwa kakhulu ngoba anikeza amandla asebenziseka kakhulu kanye nokuphila isikhathi eside komjikelezo.
Umthamo webhethri ungenye yezinto ezibaluleke kakhulu ekuklameni uhlelo lwamandla elanga olungaphandle kwegridi. Usayizi webhethri ofanele uncike kulokho onakhoukusetshenziswa kwamandla kwansuku zonke, izidingo zesipele, kanye nohlobo lwebhethri.
Ngenjwayelo:
- Izinhlelo ezincane zingadinga5–10 kWh yesitoreji
- Izinhlelo zokuhlala zingadinga10–30 kWh
- Izinhlelo ezinkulu zezentengiselwano zingadinga50 kWh noma ngaphezulu
Ngokubala ngokucophelela izidingo zakho zamandla nokukhetha ubuchwepheshe bebhethri obufanele, ungakha uhlelo lwelanga oluthembekile olungaphandle kwegridi oluhlinzeka ngogesi ozinzile imini nobusuku.
Ukusebenza nabaphakeli belanga abanolwazi kungasiza ekuqinisekiseni ukuthi uhlelo lunosayizi ofanele futhi lulungiselelwe ukusebenza kwesikhathi eside.
