Iintlobo zee-inverters zokugcina amandla endlu
Ii-inverters zokugcina amandla okuhlala zingahlelwa zibe ziindlela ezimbini zobugcisa: ukudibanisa kwe-DC kunye nokudibanisa kwe-AC.Kwinkqubo yokugcina i-photovoltaic, amacandelo ahlukeneyo afana neepaneli zelanga kunye neglasi ye-PV, abalawuli, ii-inverters zelanga, iibhetri, imithwalo (izixhobo zombane), kunye nezinye izixhobo zokusebenza kunye.Ukudityaniswa kwe-AC okanye kwe-DC kubhekisa kwindlela iipaneli zelanga eziqhagamshelwe ngayo kugcino lwamandla okanye kwiinkqubo zebhetri.Ukudibanisa phakathi kweemodyuli zelanga kunye neebhetri ze-ESS zingaba yi-AC okanye i-DC.Ngelixa uninzi lweesekethe ze-elektroniki zisebenzisa umsinga othe ngqo (DC), iimodyuli zelanga zivelisa ngokuthe ngqo okwangoku, kwaye iibhetri zelanga zasekhaya zigcina umsinga othe ngqo, izixhobo ezininzi zifuna umbane otshintshayo (AC) ukuze usebenze.
Kwinkqubo yokugcinwa kwamandla elanga edibeneyo, i-current ngqo eyenziwa ngamapaneli elanga igcinwa kwi-bettery pack ngokusebenzisa umlawuli.Ukongeza, igridi inokutshaja ibhetri nge-bidirectional DC-AC converter.Indawo yokudibanisa amandla ikwisiphelo sebhetri ye-DC BESS.Emini, ukuveliswa kwamandla e-photovoltaic kuqala kunika umthwalo (imveliso yombane yasekhaya) kwaye ihlawulise ibhetri nge-MPPT isilawuli selanga.Inkqubo yokugcina amandla ixhunywe kwigridi karhulumente, evumela ukuba amandla angaphezulu afakwe kwigridi.Ebusuku, ibhetri ikhupha ukubonelela amandla kumthwalo, kunye naluphi na ukusilela okongezwa yigridi.Kuyafaneleka ukuba uqaphele ukuba iibhetri ze-lithium zibonelela kuphela amandla kwimithwalo ye-off-grid kwaye ayinakusetyenziselwa imithwalo edibeneyo yegridi xa igridi yamandla iphumile.Kwiimeko apho amandla omthwalo adlula amandla e-PV, zombini igridi kunye nenkqubo yokugcina ibhetri yelanga inokubonelela amandla kumthwalo ngaxeshanye.Ibhetri idlala indima ebalulekileyo ekulinganiseni amandla enkqubo ngenxa yendalo eguquguqukayo yokuvelisa amandla e-photovoltaic kunye nokusetyenziswa kwamandla okulayisha.Ngaphaya koko, inkqubo ivumela abasebenzisi ukuseta amaxesha okutshaja nawokukhupha ukukhawulelana neemfuno zabo zombane.
Indlela i-DC eDityanisiweyo yokuGcinwa kwaMandla eSebenza ngayo
I-Hybrid photovoltaic + inkqubo yokugcina amandla
I-inverter ye-solar hybrid inverter idibanisa kunye nokusebenza kwegridi ukunyusa ukusebenza kakuhle kokutshaja.Ngokungafaniyo ne-inverters ye-grid, ekhupha ngokuzenzekelayo inkqubo yepaneli yelanga ngexesha lokuphela kombane ngenxa yezizathu zokhuseleko, ii-inverters ze-hybrid zinika abasebenzisi amandla okusebenzisa amandla nangexesha lokucima, njengoko banokusebenza zombini ngaphandle kwegridi kwaye baqhagamshelwe kwigridi.I-advanteji yee-inverters ezixutyiweyo kukujongwa kwamandla okwenza lula ababonelela ngawo.Abasebenzisi banokufikelela ngokulula kwiidatha ezibalulekileyo ezifana nokusebenza kunye nokuveliswa kwamandla ngokusebenzisa ipaneli ye-inverter okanye izixhobo ezihlakaniphile ezixhunyiwe.Kwiimeko apho isistim ibandakanya ii-inverters ezimbini, nganye kufuneka ibekwe esweni ngokwahlukileyo.Ukudibanisa kwe-DC kuqeshwe kwii-inverters ezixubileyo ukunciphisa ilahleko kukuguqulwa kwe-AC-DC.Ukutshaja kwebhetri ngokufanelekileyo ngokudityaniswa kwe-DC kunokufikelela malunga ne-95-99%, xa kuthelekiswa ne-90% ngodibaniso lwe-AC.
Ngaphaya koko, ii-inverters ezixutyiweyo zinoqoqosho, zihlangene, kwaye kulula ukuzifaka.Ukufakela i-inverter entsha edibeneyo kunye neebhetri ezidityanisiweyo ze-DC kunokuba yindleko ngakumbi kunokubuyisela iibhetri ezidityanisiweyo ze-AC kwinkqubo ekhoyo.Izilawuli zelanga ezisetyenziswe kwii-inverters ezixubileyo zingabizi kakhulu kune-grid-tied inverters, ngelixa ukutshintshwa kokutshintshwa kuncinci kuneekhabhinethi zokuhambisa umbane.I-DC yokudibanisa i-solar inverter inokudibanisa imisebenzi yokulawula kunye ne-inverter kumatshini omnye, okukhokelela ekugcinweni okongeziweyo kwizixhobo kunye neendleko zokufakela.Ukusebenza kweendleko zesixokelelwano sokudityaniswa kwe-DC kubonakaliswa ngokukodwa kwiisistim ezincinci kunye neziphakathi kwigridi yokugcina amandla.Uyilo lwemodyuli yee-inverters ezixutyiweyo zivumela ukongezwa lula kwamacandelo kunye nabalawuli, kunye nokhetho lokubandakanya amacandelo ongezelelweyo usebenzisa isilawuli selanga se-DC esingabizi kakhulu.Ii-inverters ze-Hybrid nazo zenzelwe ukuququzelela ukuhlanganiswa kokugcinwa nanini na, ukwenza lula inkqubo yokongeza iipakethi zebhetri.Inkqubo ye-inverter ye-hybrid ibonakaliswe ngobungakanani bayo obudibeneyo, ukusetyenziswa kweebhetri eziphezulu zombane, kunye nokunciphisa ubungakanani bekhebula, okukhokelela kwilahleko ephantsi.
