Ukuba uceba ukufaka ibhetri yelanga okanye yelanga ekhayeni lakho, kukho umbuzo injineli enokuwubuza ngokuqinisekileyo, ingaba ikhaya lakho liza kuba linye okanye liza kuba nesigaba sesithathu?
Ngoko ke namhlanje, makhe sifumanise ukuba ithetha ukuthini kanye kanye nendlela esebenza ngayo xa kufakelwa ibhetri yelanga okanye yelanga.
Kuthetha ukuthini isigaba esinye kunye nesigaba sesithathu?
Akungathandabuzeki ukuba isigaba ebesisoloko sithetha ngaso sibhekisa ekusasazweni komthwalo. Isigaba esinye yintambo enye exhasa usapho lwakho lonke, ngelixa isigaba sesithathu yintambo ezintathu zokuxhasa.
Ngokwesiqhelo, i-single-phase yintambo enye esebenzayo kunye ne-neutral edibanisa nendlu, ngelixa i-three-phase iyintambo ezintathu ezisebenzayo kunye ne-neutral edibanisa nendlu. Ukusasazwa kunye nolwakhiwo lwale ntambo kubangelwa kukusasazwa kwemithwalo esisandula ukuthetha ngayo.
Ngaphambili, uninzi lwezindlu bezisebenzisa izibane, iifriji kunye neethelevishini ezinesigaba esinye. Kwaye kule mihla, njengoko sonke sisazi, akukho kuphela ukuthandwa kwezithuthi zombane, kodwa nakwikhaya apho uninzi lwezixhobo zixhonywa eludongeni kwaye kukho into evulekayo nanini na xa sithetha.
Ngoko ke, umbane onezigaba ezintathu waqala, kwaye izakhiwo ezintsha ezininzi zisebenzisa izigaba ezintathu. Kwaye iintsapho ezininzi zinomnqweno onamandla wokusebenzisa umbane onezigaba ezintathu ukwanelisa iimfuno zobomi bazo bemihla ngemihla, oku kungenxa yokuba izigaba ezintathu zinezigaba ezintathu okanye iingcingo zokulinganisela umthwalo, ngelixa izigaba esinye zinesinye kuphela.
Zifakwa njani ngebhetri yelanga okanye yelanga?
Ukufakelwa phakathi kwe-solar enezigaba ezintathu kunye ne-solar enezigaba enye kuyafana ukuba sele unayo amandla ezigaba ezintathu endlwini yakho. Kodwa ukuba akunjalo, inkqubo yokuphucula ukusuka kwi-solar enezigaba enye ukuya kwezintathu yeyona nto inzima ngexesha lokufakelwa.
Yintoni umahluko ophambili kufakelo lwamandla olunezigaba ezintathu? Impendulo luhlobo lwe-inverter. Ukuze kulungiswe umbane osetyenziswa ekhaya, inkqubo yebhetri yelanga + yesigaba esinye idla ngokusebenzisa i-inverter yesigaba esinye ukuguqula umbane we-DC ogcinwe kwiiseli zelanga kunye neebhetri zibe ngumbane we-AC. Kwelinye icala, i-inverter yesigaba sesithathu iya kusetyenziswa kwinkqubo yebhetri yelanga + yezigaba ezintathu ukuguqula umbane we-DC ube ngumbane we-AC kunye nezigaba ezintathu ezisasazwa ngokulinganayo.
Kwakhona abanye abantu abanokukhetha umthombo wamandla wesigaba sesithathu onomthwalo omkhulu banokufakelwa i-inverter yesigaba esinye. Kodwa ke umngcipheko uya kwanda emva koko kwaye kunzima ukulawula amandla avela kwizigaba ezahlukeneyo. Kwangaxeshanye iintambo kunye nee-circuit breakers ziyamangalisa ukuba ezi zixhobo zidibanise inkqubo.
Ukuya kuthi ga kwinqanaba elithile, iindleko zokufaka inkqubo yebhetri yelanga + yesigaba sesithathu zinokuba phezulu kunenkqubo yebhetri yelanga + yesigaba esinye. Oku kungenxa yokuba iinkqubo zebhetri yelanga + yesigaba sesithathu zinkulu, zibiza kakhulu, kwaye ziyinkimbinkimbi kwaye zithatha ixesha ukuzifaka.
Ungayikhetha njani amandla esigaba esinye okanye amathathu?
Ukuba ungathanda ukwenza ukhetho olufanelekileyo lokukhetha inkqubo yelanga enamanqanaba amathathu okanye enye, kuxhomekeke kwiinkcukacha zokusetyenziswa kombane. Xa imfuno yombane iphezulu, inkqubo yelanga enamanqanaba amathathu yeyona ilungileyo. Ngoko ke iluncedo kumandla orhwebo, amakhaya anezithuthi zamandla ezintsha okanye amadama okudada, amandla emizi-mveliso, kunye nezinye izakhiwo ezinkulu zeeflethi.
Inkqubo yelanga enamanqanaba amathathu ineengenelo ezininzi, kwaye ezona nzuzo zintathu ziphambili zezi: i-voltage ezinzileyo, ukusasazwa ngokulinganayo kunye neentambo ezingabizi kakhulu. Asisayi kuphinda sicaphuke kukusetyenziswa kombane okungazinzanga kuba i-voltage egudileyo iya kunciphisa umngcipheko wokonakala kwezixhobo, ngelixa amandla alinganayo aya kunciphisa umngcipheko weesekethe ezimfutshane. Ngale ndlela, nangona iinkqubo zelanga ezinamanqanaba amathathu zibiza kakhulu ukufakelwa, ixabiso lezinto ezisetyenziswa ekunikezeleni umbane liphantsi kakhulu.
Nangona kunjalo, ukuba awudingi mandla amaninzi, inkqubo yelanga enamanqanaba amathathu ayilokhetho olufanelekileyo. Umzekelo, iindleko zee-inverters zeenkqubo zelanga ezinamanqanaba amathathu ziphezulu kwezinye izinto, kwaye xa kukho umonakalo kwinkqubo, iindleko zokulungisa ziya kunyuka ngenxa yeendleko eziphezulu zenkqubo. Ngoko ke kubomi bethu bemihla ngemihla asifuni mandla amaninzi, inkqubo enesigaba esinye inokwanelisa ngokupheleleyo imfuno yethu, okufanayo nakuninzi lweentsapho.
