Njengoko iimfuno zamandla zisanda kwaye ukuthembeka kwegridi kuncipha, izisombululo zebhetri yelanga engaphandle kwegridi ziyayitshintsha indlela iiprojekthi ezikude ezifikelela ngayo kumbane. Kubathengisi belanga abathengisa ngobuninzi, abafaki, abasasazi, kunye nabakhi be-EPC, ukuqonda indlela iinkqubo zokugcina amandla ebhetri (i-BESS) ezisebenza ngayo ngokuzimeleyo kwigridi kubalulekile ekwandiseni kwiimarike ezintsha. Esi sikhokelo siphendula imibuzo ephambili malunga ne-BESS engaphandle kwegridi kwaye sigxininisa oko abathengi be-B2B kufuneka bakuhlole.
Inkqubo yokugcina amandla ebhetri isebenza njani ngaphandle kwegridi?
I-BESS engaphandle kwegridi isebenza ngokuzimeleyo kwigridi yombane. Idibanisa uluhlu lwelanga kunye ne-Ibhetri yelanga yeLiFePO4kunye ne-inverter ukwenza i-microgrid ezixhasayo. Emini, iiphaneli zelanga zivelisa umbane ukuze zinike amandla imithwalo kwaye zitshaje ibhetri. Ebusuku okanye ngamaxesha amafu, i-BESS ikhupha amandla agciniweyo ukuze igcine amandla.
Kwabafaki, umahluko ophambili yindima ye-inverter. Ii-inverter ezingasebenzi kwigridi kufuneka zilawule i-frequency kunye ne-voltage ngokuzimeleyo, kwaye i-BMS eqinileyo (iNkqubo yoLawulo lweBhetri) ibalulekile ukuthintela ukukhupha i-over-discharge kunye nokuqinisekisa ukuba iiseli zebhetri zihlala zilungelelene.
Kutheni iLiFePO4 Solar Battery Tech ikhokela iiprojekthi ezingaphandle kwegridi
Kwizicelo zebhetri ezikude okanye zorhwebo, ikhemistri yeLiFePO4 yeyona isemgangathweni kushishino. Ngokungafaniyo nezinye iindlela ze-lead-acid, iibhetri zelanga zeLiFePO4 zibonelela ngezi zinto zilandelayo:
♠PhezuluUbunzulu bokukhupha(DoD): Ukusetyenziswa ngokukhuselekileyo okunomthamo ofikelela kwi-80-90%.
♠Ukhuseleko Oluphezulu: Uzinzo oluphezulu lobushushu, olubalulekileyo kwiindawo ezingenabantu okanye ezikude.
♠Ubomi boMjikelo Omde: Iibhayisekile ezingaphezu kwama-6,000, nto leyo enciphisa uhambo lokulungisa kwiindawo ezikude.
Xa kuvavanywa iiseli zebhetri, abathengi be-B2B kufuneka bacele isiqinisekiso (UL, IEC, UN38.3) baze baqinisekise ukuba iiseli zebhetri ziyahambelana nomthamo obhengeziweyo kunye no-q.ubunyani.
Ukuqonda Ugcino lweSolar Plus kwizicelo ezingaphandle kweGridi
Ingcamango yokubaindawo yokugcina amandla elanga kunye ne-solaribaluleke kakhulu kwiimeko ezingaphandle kwegridi. Ngaphandle kwegridi njengenkxaso-mali, amandla kufuneka alawulwe ngononophelo. Inkqubo yokugcina amandla elanga iqinisekisa ukuba ukuveliswa kwamandla elanga akuchithwa kodwa kugcinwe kwimithwalo ebalulekileyo efana nefriji, unxibelelwano, okanye ukupompa amanzi.
Kwabakhi be-EPC, ukuyila inkqubo engaphandle kwegridi kufuna uhlalutyo oluchanekileyo lomthwalo. Ukusebenzisa iiyunithi ze-ESS ezisebenzayo kakhulu kuzo zonke—ukudibanisa i-inverter,I-BMS, kunye nebhetri yelanga yeLiFePO4 kwi-enclosure enye—yenza kube lula ukufakela kwaye kunciphisa ubunzima beentambo kwiindawo ezikude.
Yintoni ekufuneka abathengi be-B2B bayijonge kwi-Off-Grid BESS?
Xa kuthengwa ibhetri yokugcina amandla elanga engaphandle kwegridi, amaqela okuthenga kufuneka agxile koku kulandelayo:
♣Ukuhlanganiswa kweNkqubo: Ngaba iprotocol yonxibelelwano lwe-BMS iyahambelana ne-inverter?
♣Isiqinisekiso: Ngaba inkqubo inesiqinisekiso sebhetri esisebenzayo sokhuseleko kunye nokuthuthwa?
♣Ukwanda: Ngaba inkqubo inokwandiswa njengoko iimfuno zamandla zikhula?
♣Ukuqina Kwendalo: Ngaba iiseli zebhetri ziyakwazi ukumelana namaqondo obushushu aphezulu kunye nokufuma?
FAQ:
Umbuzo 1: Ngaba i-BESS ingasebenza ngokupheleleyo ngaphandle kwegridi?
