Into yindlela ebalulekileyo ekusebenzeni nezindlela zokuphatha amandla ngokuphezulu kuyiindawo zokugcinwa kwamandla fano nokuthi indlela ohlangabezana ngayo kakhulu ngokuhlangana kwakho kwezinhlayiya zakho nezinhlayiya zakho zasemvini. Ezimbili ziyisisekelo ziyi AC-coupled ne DC-coupled. Ukubona ukuthi ziyisiphi ososizo ukukhetha okungcono kakhulu kwezindawo zakho zokuhlalla noma kwezifiso zakho.
Ukubuka ngokujwayelekile: Yiziphi i-AC-Coupled ne DC-Coupled Systems?
Ukuze kwenzeke kakhulu ukuthi kubonakale, ukutholakala kuyindlela omandla ikhwekhana ngayo phakathi kwezinhlayiya zakho, izinhlayiya zakho zokugcinwa fano nezinhlayiya zakho zasemvini.
Indlela enye yabo yokuqondile yisistimu esihlanuweyo kuma-DC. I-photovoltaic panels iyakhiwa ngamandla we-DC (Direct Current). Le ndawo ye-DC iyathunyelwa ngqo kwi-battery bank ethile kwaye incedwa ngamandla ngu-DC. Xa kufuneka usebenzise le ndawo ukuze wenze imicimbi yakho yendawo, edinga i-Alternating Current (AC), i-inverter iyagcina amandla we-DC kuma-AC. Yimagina ukuba yindlela enye phakathi kwe-panels kunye ne-battery.
Indlela enye engcono yisistimu esihlanuweyo kuma-AC. I-inverter yakhe iyagcina i-DC electricity ye-solar panels ngqo kuma-AC electricity. Le ndawo ye-AC ingasebenziswe kuyo ndawo yakho. Yonke indawo engcono ingasebenziswe kwi-inverter evela phezulu, e-inverter enye engenakho ingxakelela kwi-battery. Le inverter iyagcina amandla we-AC ubube kuma-DC ethile kwaye incedwa. Xa siya kusebenzisa amandla we-AC ethile i-inverter ekhoyo kwi-battery iyagcina amandla ngokuphela kuma-AC.
Iindlela ebalulekileyo kwi-installation kunye nesakhelo sistimu
Ukuhlukana okulula kokuqondiswa kwabo kwelekthrisithi kubangela ukuhlukena okukhulu kwezinhlelo zokusebenza.
Ukuhlelwa kwezimali neSethemba le-Inverter: Isethemba se-DC-coupled inenye i-inverter ephambene nehhafu inokusebenzisa ngokuphambene nezinhloso zokuphatha nezokugcinwa kwebhatteri. Kungenzeka ukuthi kubangela isethemba esifanele kakhulu. Isethemba se-DC-coupled singcono kudinga amainverter amabili angaphambene, enye yokuqembela izinhloti zasematholeni neyoku yokuqembela bhatteri. Lokhu kungaba yinkimbinkimbi engezwa futhi isethemba esingenhla sokufaka.
Ukuhlanganiswa: Izinhlelo zokuhlanganiswa ne-AC kutholakale kakhulu ngokuhlanganiswa kwazo. Kungenzeka ukuthi kuzwakale kakhulu ngaphandle kwezinhlelo zasematholeni ezivelelwe. Ngokuba bhatteri ine AC circuit yayo, kungenzeka ukuthi kudisiwe kuzo ngokungenakanywa kakhulu. Isikweletu esithandwa kakhulu kwezinhlelo zokufaka nezinhlelo zase-DC-coupled siboniswa njenge-investment enye njengesihlahla esinye.
Ukuchitha nokuphepha: Ngamunye ohathwayo ube kube ngalokho, DC ku-AC noma uyisisekelo amandla athile ayahlela ekuphatheni, ngokwezindleko. Indawo egcwele DC kudinga ukuguqula okungenani kwezinye zokulayisha amagenge, ngokwesiqephu indawo enobungozi obungcono. Indawo egcwele AC iyahlela kakhulu futhi lokhu kungakho ukuthi ukusebenza kwenye kungaphansi. Indawo egcwele AC ungakho inani elikhulu lezinto ezingcono, ngoba inamanye amagqamisa (abakhethi babili).
Noma Bese Ukhetha Ukugcinwa kwe DC-Coupled Ukuze Ukuhlele?
Noma ngoba amathathu amabili awusebenza, indawo egcwele DC ngu-ye ngokuvamile engcono yokusebenzisa lapho kusebenza nokuchitha kuyindlela ephambene.
Ukuqoqwa kwe-DC kungenzeka ukutholwa kakhulu yezinsiza eziya emiseni ngokukodwa kuzindlela zokuphazamiseka ngaphandle kwe-grid. Kuyindlela yokusebenza okuphakathi okwenza i-paneli zakho zonke ukuthola kakhulu kwezinye zokulinda. Lokhu kubaluleke lapho kunezinye zokusebenza kwe-kilowatt-hour futhi akukho ukuxhumana nezinhloso zokuphazamiseka okuphezulu.
Lokhu kusebenza kakhulu kwenza i-DC-coupled systems kube yisicelo esifanele kuzindlela zokusebenza noma yisiphi isimo lapho isihloko siyokuthi kwehlise ukungena kwezinye futhi uthole kakhulu kwezinye. Ukunakekela kwezinye ngokukhulu ngepaneli eziyina zonke kungenzeka ukuthi kwenzeke ukuthola okuningi kuzinye zokudla.
