Uma uhlala endaweni enesimo sezulu esibi kakhulu noma ukucima kukagesi okuvamile, kungumqondo omuhle ukuba nomthombo wamandla ongeziwe wekhaya lakho. Kunezinhlobo ezahlukene zezinhlelo zamandla ongeziwe emakethe, kodwa ngayinye inenhloso efanayo eyinhloko: ukugcina izibani zakho nezinto zikagesi zivuliwe lapho ugesi ucimile.

Kungaba unyaka omuhle ukubheka amandla okusekelayo: Ingxenye enkulu yeNyakatho Melika isengozini enkulu yokucima kukagesi kuleli hlobo ngenxa yesomiso esiqhubekayo futhi kulindeleke ukuthi amazinga okushisa aphezulu kunesilinganiso, kusho iNorth American Electric Reliability Corporation ngoLwesithathu. Izingxenye ze-United States, kusukela eMichigan kuya eGulf Coast, zisengozini enkulu yokwenza ukucima kukagesi kube nokwenzeka kakhulu.

Esikhathini esidlule, amajeneretha asebenza ngophethiloli (aziwa nangokuthi amajeneretha endlu yonke) ayebusa imakethe yokuphakelwa kwamandla okusekelayo, kodwa imibiko yengozi yobuthi be-carbon monoxide iholele abaningi ekufuneni ezinye izindlela. Ama-backup ebhethri avele njengenketho enobungani nemvelo futhi engaba iphephe kakhulu kunezijeneretha ezivamile.

Naphezu kokwenza umsebenzi ofanayo, ama-backup nama-generator ebhethri angamadivayisi ahlukene. Ngayinye iyisethi ekhethekile yezinzuzo nokungalungi, esizoyixoxa kumhlahlandlela wokuqhathanisa olandelayo. Qhubeka ufunda ukuze uthole ngomehluko omkhulu phakathi kwama-backup ebhethri nama-generator bese unquma ukuthi iyiphi inketho engcono kakhulu kuwe.

Amakhophi agciniwe ebhethri
Izinhlelo zokulondoloza amabhethri asekhaya, njenge-Tesla Powerwall noma i-LG Chem RESU, zigcina amandla, ongawasebenzisa ukuze unike amandla indlu yakho ngesikhathi sokungasebenzi. Amabhethri okulondoloza asebenza ngogesi, kungaba ngohlelo lwakho lwelanga lwasekhaya noma kugridi kagesi. Ngenxa yalokho, angcono kakhulu endaweni ezungezile kunezinjini eziphehla uphethiloli. Angcono futhi esikhwameni sakho semali.

Ngokwehlukile, uma unohlelo lokusetshenziswa kwesikhathi, ungadinga uhlelo lokusekela ibhethri ukuze wonge imali ezindlekweni zakho zamandla. Esikhundleni sokukhokha amanani aphezulu kagesi ngesikhathi samahora okusetshenziswa okuphezulu, ungasebenzisa amandla avela kubhethri lakho lokusekela ukuze unike amandla ikhaya lakho. Ngamahora angekho aphezulu, ungasebenzisa ugesi wakho njengenjwayelo - kodwa ngentengo eshibhile.

Ngakolunye uhlangothi, amajeneretha ahlala elindile axhuma kuphaneli kagesi yendlu yakho bese evula ngokuzenzakalelayo lapho ugesi ucimile. Amajeneretha asebenza ngophethiloli ukuze agcine ugesi wakho uvuliwe ngesikhathi sokucima — ngokuvamile igesi yemvelo, i-propane ewuketshezi noma idizili. Amajeneretha engeziwe anesici "sophethiloli oluphindwe kabili", okusho ukuthi angasebenza kugesi yemvelo noma i-propane ewuketshezi.

Amanye amajeneretha egesi yemvelo kanye ne-propane angaxhuma kumugqa wegesi wekhaya lakho noma ethangini le-propane, ngakho-ke asikho isidingo sokuwagcwalisa ngesandla. Nokho, amajeneretha edizili kuzodingeka agcwaliswe ukuze aqhubeke esebenza.

Isipele sebhethri vs. ijeneretha: Ziqhathaniswa kanjani?
Intengo
Ngokuphathelene nezindleko,izipele zebhethriyizona zinketho ezibiza kakhulu kusengaphambili. Kodwa abakhiqizi badinga uphethiloli ukuze basebenze, okusho ukuthi uzochitha isikhathi esiningi ukuze ugcine uphethiloli uzinzile.

Ngama-backup ebhethri, kuzodingeka ukhokhele uhlelo lwebhethri oluyisipele kusengaphambili, kanye nezindleko zokufaka (ngalinye lazo liyizinkulungwane). Amanani aqondile azohluka ngokuya ngokuthi ukhetha yiphi imodeli yebhethri nokuthi zingaki ozidingayo ukuze unike amandla ikhaya lakho. Kodwa-ke, kuvamile ukuthi uhlelo oluyisipele lwebhethri lasekhaya olujwayelekile lusebenze phakathi kuka-$10,000 no-$20,000.

Kumajeneretha, izindleko zokuqala ziphansi kancane. Ngokwesilinganiso, intengo yokuthenga nokufaka ijeneretha ebekwe eceleni ingasukela ku-$7,000 kuya ku-$15,000. Kodwa-ke, khumbula ukuthi amajeneretha adinga uphethiloli ukuze asebenze, okuzokwandisa izindleko zakho zokusebenza. Izindleko ezithile zizoncika ezintweni ezimbalwa, okuhlanganisa usayizi wejeneretha yakho, uhlobo luni lukaphethiloli olusebenzisayo kanye nenani likaphethiloli elisetshenziswayo ukuze lisebenze.

Ukufakwa
Ama-backup ebhethri athola inzuzo encane kulesi sigaba ngoba angafakwa odongeni noma phansi, kanti ukufakwa kwejeneretha kudinga umsebenzi owengeziwe. Noma kunjalo, kuzodingeka uqashe uchwepheshe wanoma yiluphi uhlobo lokufakwa, kokubili okuzodinga usuku lonke lomsebenzi futhi kungabiza izinkulungwane zamaRandi.

Ngaphandle kokusetha idivayisi ngokwayo, ukufaka ijenereyitha kudinga nokuthulula i-slab yekhonkrithi, ukuxhuma ijenereyitha nomthombo kaphethiloli okhethekile kanye nokufaka iswishi yokudlulisa.

Ukulungiswa
Ama-backup ebhethri yiwona aphumelelayo kulesi sigaba. Athule, asebenza ngokuzimela, awakhiqizi ukukhishwa kwegesi futhi awadingi ukulungiswa okuqhubekayo.

Ngakolunye uhlangothi, amajeneretha angaba nomsindo kakhulu futhi aphazamise uma esetshenziswa. Aphinde akhiphe umoya noma intuthu, kuye ngokuthi asebenzisa luphi uhlobo lukaphethiloli — okungase kukucasule wena noma omakhelwane bakho.

Ukugcina ikhaya lakho lisebenza kahle

Ngokuphathelene nokuthi bangagcina isikhathi esingakanani besebenzisa ikhaya lakho, amajeneretha asebenza kahle adlula kalula amabhethri asekelayo. Uma nje unephethiloli eyanele, amajeneretha angasebenza ngokuqhubekayo kuze kube amasonto amathathu ngesikhathi (uma kudingeka).

Akunjalo ngamabhethri asekelayo. Ake sisebenzise i-Tesla Powerwall njengesibonelo. Inesitoreji esingama-kilowatt-hours angu-13.5, esinganikeza amandla amahora ambalwa sodwa. Ungathola amandla engeziwe kuzo uma ziyingxenye yesistimu yephaneli yelanga noma uma usebenzisa amabhethri amaningi ohlelweni olulodwa.

Isikhathi sokuphila esilindelekile kanye newaranti
Ezimweni eziningi, ama-backup ebhethri aneziqinisekiso ezinde kunezinjini ezisebenza zilindile. Kodwa-ke, lezi ziqinisekiso zilinganiswa ngezindlela ezahlukene.

Ngokuhamba kwesikhathi, izinhlelo zokulondoloza ibhethri zilahlekelwa ikhono lokubamba ukushaja, njengamafoni nama-laptop. Ngaleso sizathu, ukulondoloza ibhethri kuhlanganisa isilinganiso somthamo wokuphela kwewaranti, esilinganisa ukuthi ibhethri lizobamba ukushaja ngempumelelo kangakanani ekupheleni kwesikhathi salo sewaranti. Endabeni kaTesla, inkampani iqinisekisa ukuthi ibhethri le-Powerwall kufanele ligcine u-70% wamandla alo ekupheleni kwewaranti yalo yeminyaka eyi-10.

Abanye abakhiqizi bamabhethri asekelayo banikeza newaranti "yokusebenzisa amandla amaningi". Lena inani lemijikelezo, amahora noma amandla akhishwayo (okwaziwa ngokuthi "ukusebenzisa amandla amaningi") inkampani eqinisekisa ngalo ibhethri layo.

Ngamajeneretha asebenza isikhathi eside, kulula ukuqagela isikhathi sokuphila. Amajeneretha asezingeni elihle angasebenza amahora angu-3,000, uma nje enakekelwa kahle. Ngakho-ke, uma usebenzisa ijeneretha yakho amahora angu-150 ngonyaka, khona-ke kufanele ihlale iminyaka engaba ngu-20.

Yikuphi okufanele wena?
Kuzo zonke izigaba eziningi,isipele sebhethriIzinhlelo ziphuma phambili. Ngamafuphi, zingcono endaweni ezungezile, kulula ukuzifaka futhi zishibhile ukuzisebenzisa isikhathi eside. Ngaphezu kwalokho, zinewaranti ende kunezinjini ezisebenza zilindile.

Nokho, amajeneretha endabuko angaba inketho enhle kwezinye izimo. Ngokungafani nama-backup ebhethri, udinga ijeneretha eyodwa kuphela ukuze ubuyisele ugesi uma ucimile, okwehlisa izindleko zangaphambilini. Ngaphezu kwalokho, amajeneretha alindile angahlala isikhathi eside kunezinhlelo zokulondoloza ibhethri ngesikhathi esisodwa. Ngenxa yalokho, azoba ukubheja okuphephile uma ugesi ucimile izinsuku eziningi.
