Njengoko imfuno yezisombululo zamandla azinzileyo iqhubeka nokunyuka, iinkqubo zamandla elanga ezingaphandle kwegrid ziye zafumana ukuthandwa okukhulu.Ezi nkqubo zixhomekeke kumacandelo ayimfuneko afana neepaneli zelanga kunye nee-inverters ukudibanisa nokuguqula amandla elanga abe ngumbane osebenzisekayo.Nangona kunjalo, enye into ebalulekileyo ehlala ingaqatshelwa yibhetri esetyenziswa kwi-inverter yelanga.Kweli nqaku, siza kuphonononga iipropati ezithile ezifunekayo kwiibhetri ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide kwi-off-grid ufakelo lwelanga, kunye nokucebisa iibhetri ezingcono kakhulu kule njongo.
IiMfuno eziPhambili kwiibhetri zeSolar Inverter
1. Ukwazi ukutshaja ngokukhawuleza:
I-off-grid inverters yelanga ifuna iibhetri ezinokutshaja ngokukhawuleza nangokufanelekileyo.Oku kubalulekile ukuqinisekisa unikezelo lombane oluzingileyo, ngakumbi ngamaxesha okukhanya kwelanga okuphantsi.Iibhetri eziqhelekileyo zesiqhelo azenzelwanga ukutshaja ngokukhawuleza, nto leyo eyenza ukuba ingafanelanga ukusetyenziswa kwiinkqubo zamandla elanga.
2. Umthamo wokukhupha ubunzulu:
Iinkqubo zebhetri ze-off-grid inverters zelanga kufuneka zikwazi ukumelana nemijikelo enzulu yokukhupha ngaphandle komonakalo.Njengoko ukuveliswa kwamandla elanga kunokwahluka kakhulu imini yonke, iibhetri kufuneka zikhutshwe ngamaxesha athile ngokupheleleyo.Nangona kunjalo, iibhetri eziqhelekileyo azenzelwanga ukumelana nemijikelo enzulu ngolo hlobo, izenza zingathembeki kwaye zinciphise ubomi benkqubo yonke.
3. UBomi boMjikelo wokuTyala okuPhezulu:
Ubomi bomjikelo wentlawulo bubhekiselele kwinani lentlawulo epheleleyo kunye nemijikelo yokukhupha ibhetri enokumelana nayo ngaphambi kokuba ukusebenza kwayo kuthotywe.Ukunikezelwa kobume bexesha elide leenkqubo zamandla elanga, iibhetri ezisetyenziswa kwii-inverters zelanga kufuneka zibe nomjikelo wentlawulo ephezulu ukuze kuqinisekiswe ubomi obude kunye nokusebenza kakuhle kweendleko.Ngelishwa, iibhetri eziqhelekileyo zihlala zinobomi bomjikelo wentlawulo ephantsi ukuya ephakathi, nto leyo ezenza ukuba zingalungeli kakhulu usetyenziso lwelanga olungekho kwigridi.
Iibhetri ezigqwesileyo ze-off-grid inverters zelanga:
1. Iibhetri zeLithium Iron Phosphate (LiFePO4):
Iibhetri ze-LiFePO4 ziye zaba lolona khetho luphezulu lofakelo lwelanga ngaphandle kwegrid ngenxa yokusebenza kwazo okubalaseleyo kunye nokuphila ixesha elide.Ezi bhetri zinokuhlawuliswa kumazinga aphezulu, zinokukhutshwa nzulu ngaphandle komonakalo kwaye zibe nobomi bokujikeleza okuphawulekayo.Ukongeza, iibhetri ze-LiFePO4 zikhaphukhaphu, zihlangene kwaye zifuna ukugcinwa okuncinci, okuzenza zibe lukhetho olufanelekileyo kwiinkqubo zamandla avuselelekayo.
2. Iibhetri zeNickel Iron (Ni-Fe):
Iibhetri ze-Ni-Fe zisetyenzisiwe kwi-off-grid solar applications amashumi eminyaka, ngenxa yobunzima kunye nokuqina kwazo.Banokumelana nokukhutshwa okunzulu ngaphandle kokubeka esichengeni ukusebenza kwaye babe nobomi obude kakhulu bomjikelo wentlawulo kuneebhetri eziqhelekileyo.Nangona iibhetri ze-Ni-Fe zinexabiso elincinci lokuhlawulisa, ukuthembeka kwazo kwexesha elide kuzenza zibe lukhetho oludumileyo kwii-inverters zelanga ze-off-grid.
3. Iibhetri zeLithium-ion (Li-ion):
Ngelixa iibhetri ze-Li-ion ziqhelekile ngokusetyenziswa kwazo kubathengi be-elektroniki, iimpawu zabo zokusebenza ezikhethekileyo zikwabenza bafanelekele usetyenziso lwelanga ngaphandle kwegrid.Iibhetri ze-Li-Ion zibonelela ngezakhono zokutshaja ngokukhawuleza, zikwazi ukumelana nokukhutshwa okunzulu kwaye zibe nobomi obufanelekileyo bomjikelezo.Nangona kunjalo, xa kuthelekiswa neebhetri ze-LiFePO4, iibhetri ze-Li-Ion zinobomi obufutshane obufutshane kwaye zinokufuna ukugcinwa okongeziweyo kunye nokubeka iliso.
Ukuqukumbela
Iziguquli zelanga ezingaphandle kwegridi zifuna iibhetri ezikhethekileyo ezinokuhlangabezana neemfuno ezifunekayo zokutshaja ngokukhawuleza, ukukhutshwa okunzulu, kunye nobomi bomjikelo wentlawulo ephezulu.Iibhetri zemveli ziwela mfutshane kule miba kwaye, ngoko ke, azifanelekanga kwizicelo zamandla ezizinzileyo.Iibhetri ze-LiFePO4, i-Ni-Fe, kunye ne-Li-Ion zibonakalise ukuba lolona khetho lungcono kwi-off-grid yezityalo zamandla elanga, ezinikezela ukusebenza okuphezulu, ixesha elide, kunye nokuthembeka.Ngokukhetha itekhnoloji yebhetri eyiyeyona ilungileyo, abasebenzisi banokuqinisekisa ukuba ufakelo lwelanga olungekho kwigridi lusebenza kakuhle, luyabiza, kwaye luyakwazi ukuhambisa amandla acocekileyo kwiminyaka ezayo.
