Ukusetshenziswa kwe izinhlelo zokugcina amandla ekhaya sekuzuze ukuthandwa okukhulu eminyakeni yamuva, ikakhulukazi ngenxa yokukhula kwamandla avuselelekayo afana nelanga. Yiba ne-a ibhethri elifanele akusizi nje kuphela yehlisa izindleko zesikweletu sakho sikagesi, kodwa futhi ithuthukisa ukuzimela kwamandla ekhaya futhi inikeza ikhophi yasenqolobaneni uma kwenzeka ukuphela kukagesi.
Ukukhetha ibhethri lasekhaya akusona isinqumo esincane.. Kunezinhlobo eziningi, ubuchwepheshe kanye nokucushwa, ngakunye kunezinzuzo kanye nokubi. Lesi sihloko sichaza konke odinga ukukwazi ukuze ukhethe isixazululo esikahle sokugcina, ngokusekelwe ekuhlaziyeni okuphelele kwezinhlelo ezisetshenziswa kakhulu namuhla.
Liyini ibhethri lokugcina amandla ekhaya?
Ibhethri yesitoreji sasekhaya iyunithi ekuvumela ukuthi ugcine amandla kagesi, okuvela emithonjeni evuselelekayo njengamaphaneli elanga noma ngokuqondile kugridi phakathi namahora okungasebenzi. Inhloso yawo enkulu wukuvumela ukusetshenziswa kwalawo mandla ngezikhathi lapho isidingo siphezulu noma kukhona ukucisha kukagesi.
Ngokuvamile ahlanganisa iseli elilodwa noma amaningi e-electrochemical, inverter eguqula amandla abe ifomu elifanele ukusetshenziswa ekhaya, kanye nesistimu yokuphatha (BMS) elawula ukusebenza kwawo ukuze kuqinisekiswe ukuphepha nokusebenza kahle.
Ubuchwepheshe bokugcina obuyinhloko buyatholakala
Okwamanje kunezinto ezihlukile ubuchwepheshe bebhethri ukusetshenziswa kwezindawo zokuhlala. Ngayinye isabela ezidingweni ezehlukene ngokwamandla, izindleko, ukugcinwa nokuqina.
Amabhethri e-lead-acid
Ziyizo zendabuko kakhulu futhi ukonga. Asetshenziswa iminyaka ekuqalisweni kwezimoto nasezinhlelweni ze-UPS (Uninterruptible Power Supply), asekhona ekufakweni kwasekhaya ngesabelomali esiphansi.
Ventajas:
- Intengo yokuqala ephansi, ilungele amakhaya anesabelomali esiqinile.
- Ubuchwepheshe obuvuthiwe futhi owaziwayo.
Izinkinga:
- Impilo yeshelufu emfushane, mayelana nemijikelezo yokushaja engu-300-500.
- Idinga ukunakekelwa, indlela yokuhlola amazinga e-electrolyte.
- I-Bulky futhi inzima, nge-low density yamandla.
Amabhethri e-lithium
Inketho esetshenziswa kakhulu njengamanje, ikakhulukazi ngenxa yayo ukusebenza kahle, usayizi omncane kanye nempilo ende yesevisi. Kunezinhlobo ezahlukene, kodwa ezivame kakhulu emkhakheni wezindawo zokuhlala i-Lithium-Ion futhi ikakhulukazi i-Lithium Iron Phosphate (LiFePO4). Uma ufuna ukwazi okwengeziwe mayelana nokusetshenziswa kwayo, thintana amabhethri e-lithium ama-inverters.
Ventajas:
- Ukuminyana kwamandla aphezulu, bathatha indawo encane.
- Impilo ende ewusizo, nemijikelezo engaphezu kuka-4.000.
- Ngaphandle kwesondlo futhi kuphephe kakhulu.
Izinkinga:
- Intengo yokuqala ephezulu mayelana ne-lead-acid.
Ngaphakathi kwamabhethri e-lithium, i I-LiFePO4 ibaluleke kakhulu ngenxa yokuzinza kwayo okukhulu kokushisa nokuphepha komlilo, kanye nokuguga okuncane phakathi neminyaka.
Amabhethri agelezayo
Iwubuchwepheshe obusafufusa, obungakasetshenziswa kabanzi ezindaweni zokuhlala. Basebenzisa i-circulating liquid electrolyte ukugcina nokukhulula amandla.
Ventajas:
- scalability enkulu, ilungele ukusetshenziswa kwezimboni.
- Umjikelezo wempilo ende.
Izinkinga:
- Badinga indawo enkulu futhi babe nezinhlelo eziyinkimbinkimbi.
- Izindleko eziphezulu.
Izinto ezibalulekile zokukhetha ibhethri elilungile
Ngale kohlobo lwebhethri, kunemibandela ebalulekile yobuchwepheshe nesebenzayo yokwenza ukukhetha okufanele. Isinqumo esihle siqala ngokwazi ikhaya lakho, imikhuba yakho kanye nesabelomali sakho esitholakalayo..
Amandla (kWh)
Ichaza inani lamandla ibhethri elingawagcina. Kunconywa ukuthi ubale ukusetshenziswa kwansuku zonke kwekhaya lakho futhi uqinisekise ukuthi ibhethri ingakhava ingxenye enkulu yalo. Kumndeni ojwayelekile, Amandla ka-5 kuya ku-10 kWh ngokuvamile anele., futhi inganwetshwa uma ukusetshenziswa okuphezulu kulindeleke noma ukuzimela okwengeziwe kufunwa. Ungase futhi ucwaninge mayelana amabhethri amandla omoya ukuqonda kangcono amakhono.
Amandla (kW)
Ikhombisa ukuthi mangakanani amandla ibhethri elingawaletha ngesikhathi esinikeziwe. Lokhu kubalulekile uma izinto eziningi zikagesi zixhunywe ngesikhathi esisodwa. Kufanele kube ngokwanele ukugcina okokusebenza okubalulekile kuvuliwe.:
- Ifriji
- Ukukhanyisa okuyisisekelo
- Irutha namakhompyutha
- Iphampu yamanzi noma yokushisisa
Imijikelezo yokushaja nempilo yesevisi
Ibhethri elinenani eliphezulu lemijikelezo (amashaji agcwele kanye nokuphumayo) line- impilo ende yesevisi. Amabhethri e-lithium adlula imijikelezo engu-4.000; Amabhethri e-lead-acid ahlala cishe ku-500 okungenani.
Modularity kanye scalability
Izigubhu eziningi zesimanje zinikeza ukucushwa kwe-modular. Lokho kusho ukuthi, Ungaqala ngekhono eliyisisekelo futhi ulikhulise ngokuzayo. ukwengeza amayunithi engeziwe, ngakho-ke kuyasiza ukucabangela amasistimu ahlangana namanye, njenge ukufakwa kwamaphaneli elanga. Lokhu kunikeza ukuguquguquka ukuzivumelanisa nokukhula kokusetshenziswa noma ukufakwa okukhudlwana kwe-solar esikhathini esizayo.
Ukuhambisana kwe-inverter
Akuwona wonke amabhethri ahambisana nayo yonke inverter. Uma unesistimu ye-photovoltaic esivele ifakiwe, qiniseka ukuthi ibhethri likhethiwe ingahlanganiswa ngempumelelo ne-inverter kanye nohlelo lokuphatha amandla.
Ukufakwa: odongeni noma phansi
Amanye amabhethri afakwe elenga odongeni, kanti amanye apakishwe phansi. Inketho yaphansi kulula ukuyifaka futhi ayidingi ukuqinisa izindonga, ikakhulukazi kumabhethri asindayo angaphezu kuka-100 kg.
Izibonelo zezinhlelo ezidumile
Phakathi kwamamodeli avelele emakethe sithola amabhethri afana ne I-Sottlot DPE-5K, esebenzisa ubuchwepheshe be-LiFePO4, inamandla angu-5 kWh futhi isekela ukunwetshwa okufika kumayunithi ayi-16 ngokuhambisana. Inketho eqinile ephinde ifake i-BMS ehlakaniphile yokuphatha okuphephile.
Enye indlela ethokozisayo yikhithi yesigubhu se-Dowell modular, ngamaseli e-CATL kanye nomklamo ostandekayo. Ubude bayo bempilo budlula imijikelezo engu-6.000 futhi inikeza phakathi kuka-5 no-20 kWh kuye ngamamojula afakiwe, okuhlanganisa ukusebenza nomklamo wobuhle okusikhumbuza into esetshenziswayo yasendlini yesimanje. Ungabona okwengeziwe mayelana nokuhlanganiswa kwayo ne amaphaneli elanga ekhaya lakho.
Sebenzisa amacala ngokuya ngephrofayili yasekhaya
Ngokuya ngendlela yokuphila kanye nokusetshenziswa kwamandla, idinga ushintsho:
- Imindeni esebenzisa isilinganiso: Ngomthamo ophakathi kuka-5 no-10 kWh kumabhethri e-LiFePO4, ukusebenza kahle kufinyelelwa.
- Imindeni enezimoto zikagesi noma amahora amaningi ekhaya: Amandla kagesi aphezulu noma amabhethri amakhulu (>10 kWh) angathwala imithwalo enzima kakhulu.
- Izindlu ezindaweni ezingazodwa: Zidinga ukuzimela okuphelele, ngakho-ke zihlanganiswa namasistimu elanga noma amajeneretha, ngakho-ke kuyasiza ukuthola i-hybrid solar kanye nezinhlelo zomoya.
Namuhla kungenzeka Thatha ithuba lamahora angasebenzi kakhulu kugridi yamandla ukuze ushaje ibhethri futhi sisebenzise lawo mandla aqoqiwe ngezikhathi zesidingo esiphezulu, sinciphise nakakhulu umthethosivivinywa.
Amabhethri okuhlala nawo angahlanganiswa ne Amasistimu we-EMS (Uhlelo Lokuphatha Amandla) okuthuthukisa ukuphathwa kwamandla kwekhaya lonke, ukuzivumelanisa nezimo ngesikhathi sangempela ekusetshenzisweni nasekukhiqizeni i-photovoltaic.
Ukukhetha isixazululo sesitoreji samandla sasekhaya akufanele kusekelwe kuphela enanini lokuqala. Kubalulekile ukucabangela zonke izici zobuchwepheshe, ukusetshenziswa, kanye nokukhula kwesikhathi esizayo. Amabhethri, ikakhulukazi i-LiFePO4, amele ibhalansi engcono kakhulu phakathi kwezindleko, ukuqina nokuphepha namuhla, ehlinzeka ngesisombululo esisebenzayo nesingenayo i-emission esivumelana nezidingo ezintsha zomhlaba wamandla.
