Amasistimu ebhethri lasekhaya elanga angasetshenziswa kokubili njengengxenye yokugcina ugesi, akhiqizwa ngokweqile ngamaphaneli e-photovoltaic ngezikhathi zokufunwa kwamandla aphansi kanye nanjengokuhlinzekwa kwezimo eziphuthumayo. Nokho, esimweni sokugcina, umbuzo uphakama ngokuthi kuyoba isikhathi esingakanani ugesi owanele ku-isitoreji sebhethri yelanga lasekhayangesikhathi esiphuthumayo nokuthi lokhu kuncike kuphi. Ngakho sinqume ukusibhekisisa lesi sihloko. Isistimu yebhethri yasekhaya yelanga njengomthombo wamandla webhethri oyisipele Ukusetshenziswa kwesistimu yebhethri yasekhaya yelanga yokugcina amandla kanye nokunikezwa kwamandla ebhethri okuyisipele kuyisixazululo esisebenza kahle kumabhizinisi, amapulazi, kanye nemizi yangasese ngokufanayo. 
Esimweni sokuqala, ingakwazi ukufaka esikhundleni se-UPS ngokuphumelelayo, esekela ukusebenza kwamadivayisi abalulekile ngokombono wephrofayela yenkampani ngesikhathi sokunqanyulwa kwamandla okubangelwa ukwehluleka kugridi yamandla. Ngamagama alula, ukunikezwa kwamandla okungaphazamiseki (i-UPS) ezinkampanini kunganciphisa isikhathi sokuphumula kanye nokulahlekelwa okuwumphumela. Ngokuphathelene nabalimi, udaba lokugcinwa kwamandla ebhethri lubaluleke kakhulu, ikakhulukazi endabeni yamapulazi anemishini eminingi, lapho imishini eminingi kanye nezinto zokusebenza zithembele emandleni kagesi. Cabanga nje ngomonakalo ongenziwa wukuphazamiseka kokunikezwa kwamandla uma, isibonelo, uhlelo lokupholisa ubisi lungasasebenzi. Ngenxa yesistimu yebhethri yasekhaya yelanga, abalimi akusadingeki bakhathazeke ngesimo esinjalo. Futhi nakuba ukunqanyulwa kukagesi kungaphazamisi kangako ekhaya, ngokwesibonelo ngokuphathelene nokulahlekelwa okungakukhiqiza, nakho akujabulisi. Futhi abayona into emnandi. Ikakhulukazi uma ukwehluleka kuthatha izinsuku ezimbalwa noma kuwumphumela wezibhelu noma ukuhlasela kwamaphekula. Ngakho-ke, futhi kulawa mazwe ukuze uzimele kubahlinzeki bakagesi kazwelonke, kufanelekile ukubheja hhayi kuphela ekufakweni kokufakwa kwe-photovoltaic kodwa nasekugcinweni kwamandla. Masikhumbule ukuthi le makethe ikhula ngokushesha okukhulu, futhi abakhiqizi bamabhethri e-lithium benza amadivaysi angcono kakhulu. Ingabe ubude besikhathi sokunikezwa kwamandla okunikezwa isistimu yebhethri yasekhaya yelanga sincike kuphi? Njengoba ubona, ukusetshenziswa kwezinhlelo zebhethri lasekhaya lelanga nakho endimeni yokunikezwa kwamandla eziphuthumayo kuyisixazululo esingabizi kakhulu kuzo zombili izizathu zezomnotho kanye nezilula. Ukunquma ngazo, noma kunjalo, udinga ukuzikhetha ngokufanele ezidingweni zakho, ukuze isikhathi lapho amandla azogcinwa khona yisistimu yebhethri yasekhaya yelanga ihlangabezane nayo ngokugcwele. Futhi ukuhlola ukuthi ingabe ngokuqinisekile ifakwe ubuchwepheshe obufanele obuvumela ukuthi ungagcini nje ukugcina amandla avela emalini eningi futhi uwasebenzise ngezikhathi lapho ukufakwa kwe-photovoltaic kungasebenzi noma kungasebenzi kahle, njengasebusuku noma ebusika, kodwa futhi nebhethri yelanga. ikhophi yasenqolobaneni yamadivayisi asekhaya. Amandla nomthamo yimingcele ebalulekile Kungakanani okwanele, ngakolunye uhlangothi, kuncike kumingcele yayo emibili yamandla namandla. Idivayisi enamandla amakhulu kanye nesilinganiso samandla aphansi iyakwazi ukunika amandla inombolo encane yezinto zikagesi ezidingekayo zasendlini, njengesiqandisi noma isilawuli sokushisisa. Ngakolunye uhlangothi, labo abanomthamo omncane kodwa amandla aphezulu banganikeza ngempumelelo amandla okulondoloza kuwo wonke amadivaysi asendlini, kodwa okwesikhashana. Ngakho-ke, kubaluleke kakhulu ukukhetha le mingcele yezidingo zomuntu ngamunye. Ingakanani umthamo wesistimu yebhethri yasekhaya yelanga? Umthamo wesistimu yebhethri yasekhaya yelanga ichaza ukuthi angakanani amandla kagesi angagcinwa kuwo. Ngokuvamile kukalwa ngama-kilowatt-amahora (kWh) noma ama-ampere-amahora (Ah), afana namabhethri emoto. Ibalwa kusukela ku-voltage lapho idivayisi yokugcina amandla isebenza khona kanye nomthamo webhethri ovezwe ngo-Ah.Lokhu kusho ukuthi izitolo zamandla ezinebhethri engu-200 Ah esebenza ku-48 V zingagcina cishe u-10 kWh. Ingakanani amandla indawo yokugcina ibhethri yelanga yasekhaya? Amandla (isilinganiso) sendawo yokugcina ibhethri yelanga yasekhaya ikutshela ukuthi angakanani amandla ekwazi ukukunikeza nganoma yisiphi isikhathi. Ivezwa ngama-kilowatts (kW). Ngiwabala kanjani amandla nomthamo wendawo yokugcina ibhethri yelanga yasekhaya? Ukuze ubale ukuthi isitoreji sebhethri lelanga lasekhaya sizohlala isikhathi esingakanani, kufanele uqale unqume ukuthi yiziphi izinto zikagesi ofuna ukuzinika amandla bese ubala inani eliphelele eliphumayo kanye namandla azo asetshenziswa nsuku zonke ku-kWh. Ngale ndlela, kungabonakala ukuthi imodeli ethile yokugcina ibhethri yelanga yasekhaya ene-lead-acid noma amabhethri e-lithium-ion iyakwazi ukuhlinzeka zonke izinto zikagesi, noma ezikhethiwe kuphela, futhi isikhathi esingakanani. 
Umthamo wesistimu yebhethri yasekhaya yelanga kanye nesikhathi sokuhlinzeka Isibonelo, uma ngesamba esiphumayo samawathi angu-200 wamandla ezintweni zikagesi, ngokufaka i-photovoltaic, kanye namandla azo asetshenziswa ngu-1.5 kWh ngosuku, umthamo wokugcina amandla: ●2 kWh - izohlinzeka amandla cishe izinsuku eziyi-1.5, ●3 kWh ukunikeza amandla izinsuku ezi-2, ●6 kWh ukunikeza amandla izinsuku ezi-4, ●9 kWh izonikeza amandla izinsuku eziyi-8. Njengoba ubona, ukukhetha okufanele kwamandla namandla abo kuyakwazi ukunikeza amandla ayisipele ngisho nangezinsuku ezimbalwa zokuhluleka kwenethiwekhi. Izimo ezingeziwe zesikhungo sesistimu yebhethri lasekhaya lelanga elizosetshenziswa njengomthombo wamandla ongaphazamiseki Ukuze usebenzise isistimu yebhethri yasekhaya yelanga ngamandla aphuthumayo, kufanele ihlangabezane nezimo ezintathu eziyisisekelo ezithinta intengo yayo. Okokuqala ukuthi amadivaysi azosebenza lapho igridi ingasebenzi. Lokhu kungenxa yokuthi, ngenxa yezizathu zokuphepha, kokubili ukufakwa kwe-photovoltaic namabhethri emazweni amaningi anokuvikelwa kwe-anti-spike, okusho ukuthi uma igridi ingasebenzi, nayo ayisebenzi. Ngakho-ke, ukuze uwasebenzise ezimeni eziphuthumayo, udinga umsebenzi owengeziwe owenziwe ngogesi onqamula ukufakwa kugridi futhi uvumele ama-inverter ebhethri ukuthi adonse amandla kuwo ngaphandle kwamaphethini. Enye inkinga ukuthi amadivaysi asebenza ngesisekelo sei-lithium ion (li-ion) noma amabhethri e-lead acid, kufanele isebenze ngamandla aphelele ngisho nangaphandle kwegridi. Amamodeli ashibhile anakho ukuthi kwimodi ye-off-grid, amandla abo okuzisholo ehla futhi ngisho nangama-80%. Ngakho-ke, ukunikezwa kwamandla okusekela ibhethri ngokusetshenziswa kwawo akusebenzi noma kudala imikhawulo ebalulekile. Ukwengeza, isisombululo esithakazelisayo esivumela ukusetshenziswa okungenamkhawulo kwesistimu yebhethri yasekhaya yelanga yisistimu ye-elekthronikhi evumela ukuthi ukhokhise amabhethri e-lithium ion ngamandla akhiqizwa ukufakwa kwe-photovoltaic ngisho nasesimweni sokuhluleka kwegridi yamandla. Ngale ndlela, amadivaysi anganikwa amandla ngokuqhubekayo ngohlelo lwebhethri lasekhaya lelanga ngaphandle komkhawulo ngokwenani lezinsuku. Nokho, ukufakwa okunjalo kubiza kakhulu kunezixazululo ezijwayelekile. Ukufingqa, ukuthi amandla angakanani anele avela ezinhlelweni zebhethri lasekhaya lelanga kuncike kakhulu ekutheni yimaphi amadivaysi azowasebenzisa, yimaphi amabhethri afakwe ngawo, kanye namandla awo namandla, okubalulekile futhi ukusebenza kahle kwamabhethri, okuyiwo. kuthonywe inani lemijikelezo yokushaja. Ngaphezu kwalokho, unquma ukuwaxhuma ekufakweni kwe-photovoltaic, kufanelekile futhi ukunakekelwa ukuthi akuvumela ukuthi uwasebenzise ngokugcweleisipele ibhethri amandla.Ngakho-ke, ukufakwa kwabo ngeke kugweme kuphela izindawo zokuhlala ezingalungile nezinkampani zamandla kokubili amakhaya namabhizinisi, kodwa futhi kunikeza isiqinisekiso sokuzimela okuphelele uma kwenzeka ukwehluleka kwenethiwekhi.
