Abanikazi bezindlu embulungeni yonke baya ngokuya bebhanqa amaphaneli elanga nesitoreji sebhethri ukuze banqamule izikweletu zikagesi futhi bathole isivikelo ekunqameni kwegridi. Kodwa-ke, ukufaka isistimu yendawo yokugcina amandla ebhethri kuhilela okungaphezu nje kokuthenga iyunithi eshalofini. Kusukela ekulinganisweni kwesistimu nokuhambisana kukagesi kuya kuzitifiketi zokuphepha kanye nemithetho yokuxhumana yensiza, izici ezimbalwa ezibalulekile zinquma ukuthi BESS yokuhlala iletha ukonga okuthenjisiwe noma iba umthombo wokukhungatheka. Ukuqonda lokhu okucatshangelwayo okubalulekile ngaphambi kokusayina inkontileka kusiza abanikazi bezindlu bagweme amaphutha abizayo futhi kuqinisekise ukuthi uhlelo lusebenza ngendlela okulindeleke ukuba luphile ngayo iminyaka eyi-10 kuya kwengu-15.

Ukulinganisa Kwesokudla Ibhethri Lezidingo Zasekhaya

Iphutha elivame kakhulu lapho ukhetha amasistimu okugcina amandla okuhlala ukulinganisa okungalungile. Ibhethri elincane kakhulu ngeke likwazi ukumboza imithwalo ephezulu kakhulu yakusihlwa, okushiya umninikhaya esadonsa amandla egridi abizayo. Uhlelo olukhulu kakhulu lwengeza izindleko zekhephithali ezingadingekile ezinenzuzo encane eyengeziwe. Qala ngokuhlaziya amaphethini okusebenzisa ugesi wansuku zonke wekhaya, ikakhulukazi ukusetshenziswa kwakusihlwa lapho ugesi welanga ungekho. Emndenini one-solar ekhona, indawo yokuhlala efanelekile ye-BESS kufanele ilinganiswe ukuze kugcinwe inani elanele lasemini ukuze lihlanganise isikhathi esiphakathi kokushona kwelanga nesikhathi sokulala. Ukufakwa okuningi kwehla phakathi kuka-5 kWh no-20 kWh wamandla asebenzisekayo. Futhi cabangela ukuthi umninikhaya ufuna amandla ayisipele ngesikhathi sokucima—uma kunjalo, isistimu yokugcina amandla okuhlala kufanele ibe nomthamo owanele kanye namasekhethi ayisipele azinikele emithwalo ebalulekile efana nesiqandisi, izibani, nemishini yezokwelapha.

Ukuqonda Ukuhambisana Kwe-Inverter kanye Nezidingo Zokufaka

Akuwona wonke amayunithi e-BESS okuhlala asebenza ngaphandle komthungo ngokusetha ugesi okukhona kuwo wonke umuzi. Amasistimu ahlanganiswe ne-AC axhumeka ngemuva kwemitha futhi angengezwa kunoma yikuphi ukufakwa kwelanga okukhona, okuwenza kube ukukhetha okuvamile kokubuyisela emuva. Amasistimu ahlanganiswe ne-DC asebenza kahle kakhulu ekufakweni okusha kodwa adinga ama-inverter ahambisanayo ayi-hybrid. Abanikazi bezindlu kufanele futhi baqinisekise ukuthi insiza yabo yasendaweni idinga yini izitifiketi ezithile ezifana ne-UL 9540 (ukuphepha kwesistimu), UL 1973 (ibhethri), kanye ne-UL 1741 (uxhumano lwegridi). Ukufakwa kochwepheshe nguchwepheshe kagesi oqinisekisiwe akuxoxiswana ngakho, njengoba izintambo ezingafanele zingadala izingozi zomlilo noma iziqinisekiso eziyize. Ukwengeza, hlola amakhodi okwakha endawo mayelana nokubekwa kwebhethri—izindawo eziningi zokulawula zidinga ukuthi amasistimu okugcina amandla okuhlala afakwe emagaraji noma ezindongeni zangaphandle, hhayi ezindaweni zokuhlala noma amagaraji anamathiselwe ngaphandle kwezindawo ezivalekile ezilinganiselwe umlilo.

Ukwandisa Ukubuyiselwa Kwezomnotho Ngokusebenza Okuhlakaniphile

Icala lezezimali le-BESS yendawo yokuhlala lincike kakhulu kusakhiwo sezinga lokusebenziseka komnikazi wendlu. Kulabo abasezindlekweni zesikhathi sokusetshenziswa ezinomehluko omkhulu phakathi kwamazinga aphezulu kanye namazinga aphezulu, amasistimu okugcina amandla ezindawo zokuhlala angashintsha amandla elanga noma ukushajwa kwegridi ukuze kukhave izikhathi eziphezulu ezibizayo. Abanikazi bezindlu abangenazo izilinganiso zesikhathi sokusebenzisa kodwa ababhekene nezindleko zokufunwa okuphezulu noma ukulinganiselwa kwensalela okulinganiselwe basengazuza ekuzisebenziseni kwakho okwengeziwe. Amayunithi okuhlala angcono kakhulu e-BESS ahlanganisa isofthiwe yokuphatha amandla ehlakaniphile elungiselela ngokuzenzakalelayo ukushaja nokukhipha ngokusekelwe kumanani esikhathi sangempela, izibikezelo zelanga, kanye nezingozi zokucima. Amanye amasistimu futhi avumela ukubamba iqhaza ezinhlelweni zemishini yamandla abonakalayo, lapho izinsiza zikhokhela abanikazi bezindlu ngokusebenzisa amabhethri abo ukuze basekele igridi phakathi nemicimbi ephakeme kakhulu—zengeze enye futhi imali engenayo.

Ukutshalwa Kwezimali Okucatshangelwayo Ekuzimele Kwamandla Asekhaya

Ukufaka isistimu yendawo yokugcina amandla ebhethri kuyisinqumo esikhokha izinzuzo eminyakeni eminingi, kodwa kuphela uma senziwe kahle. Ukulinganisa okufanele, ukufakwa okuphrofeshinali, nokusebenza okuhlakaniphile kuguqula ibhethri lisuke kudivayisi eliyisipele elilula libe ithuluzi lezezimali elinamandla. Kwa-Wenergy, amasistimu ethu okugcina amandla okuhlala aletha amandla athembekile, ahlakaniphile, futhi angalawuleki ezindlini zesimanje. Izixazululo zethu zihlanganisa ubuchwepheshe bebhethri obuthuthukisiwe namasistimu elanga, okuvumela abanikazi bezindlu ukuthi bagcine amandla engeziwe emini ukuze bawasebenzise ebusuku noma phakathi nenani eliphakeme kakhulu. Ngokwandisa ukusetshenziswa kwakho, ukunciphisa izikweletu zikagesi, nokuqinisekisa amandla okulondoloza ngesikhathi sokuhamba-ngesikhathi sokushintshwa kwe-10ms esingenamthungo-I-Wenergy isiza abanikazi bezindlu ukuba bathole ukuzimela okukhulu kwamandla nokonga isikhathi eside. Ukuthi umgomo uwukuzisebenzisela amandla elanga, ukushefa okuphezulu, noma ukuphila ngaphandle kwegridi ngamandla okukala ukusuka ku-5 kWh kuya ku-30 kWh, Wenergy inikeza i-BESS yokuhlala eyakhelwe izindlu zangempela nokuthula kwengqondo kwangempela.
