Ngophuhliso lwetekhnoloji yemodyuli yeCell kunye ne-PV, itekhnoloji ezahlukeneyo ezifana ne-half cut cell, imodyuli ye-shingling, imodyuli yobuso be-bi-facial, i-PERC, njl njl.Amandla okuphuma kunye nokukhoyo kwimodyuli enye anyuke kakhulu.Oku kuzisa iimfuno eziphezulu kwii-inverters.
I-1.Iimodyuli zamandla aphezulu afuna ukuguquguquka okuPhezulu kwangoku kwee-Inverters
I-Imp yeemodyuli ze-PV yayijikeleze i-8A kwixesha elidlulileyo, ngoko ke igalelo eliphezulu langoku le-inverter lalihlala lijikeleze i-9-10A.Okwangoku, i-Imp ye-350-400W iimodyuli zamandla aphezulu idlulile i-10A efunekayo ukukhetha i-inverter kunye ne-12A igalelo eliphezulu ngoku okanye ngaphezulu ukuhlangabezana nemodyuli ye-PV yamandla aphezulu.
Le theyibhile ilandelayo ibonisa iiparameters zeentlobo ezininzi zeemodyuli zamandla aphezulu ezisetyenziswa kwimarike.Siyabona ukuba i-Imp yemodyuli ye-370W ifikelela kwi-10.86A.Kufuneka siqinisekise ubuninzi begalelo langoku le-inverter ukudlula i-Imp yemodyuli ye-PV.
2.Njengoko amandla emodyuli enye inyuka, inani leentambo zokufaka i-inverter lingancitshiswa ngokufanelekileyo.
Ngokunyuka kwamandla eemodyuli zePV, amandla omtya ngamnye nawo aya kwanda.Ngaphantsi komlinganiselo ofanayo womthamo, inani leMitya yokuNgena ngeMPPT liya kuncipha.
Igalelo eliphezulu langoku leRenac R3 Note Series 4-15K inverter yesigaba sesithathu yi-12.5A, enokuthi ihlangabezane neemfuno zeemodyuli ze-PV eziphezulu.
Ukuthatha iimodyuli ze-370W njengomzekelo ukulungiselela iinkqubo ze-4kW, 5kW, 6kW, 8kW, 10kW ngokulandelanayo.Iiparamitha eziphambili zee-inverters zezi zilandelayo:
Xa siqwalasela inkqubo yelanga, sinokuqwalasela i-DC oversize.Ingqikelelo ye-DC oversize yamkelwa ngokubanzi kuyilo lwesixokelelwano selanga.Okwangoku, amaziko ombane e-PV kwihlabathi jikelele sele edlulile kumndilili ophakathi kwe-120% kunye ne-150%.Esinye sezizathu eziphambili zokugqithisa i-jenereyitha ye-DC kukuba amandla eemodyuli zethiyori zihlala zingafezeki ngokwenyani.Kwezinye iindawo apho i-irradiance enganelanga, ukugqithisa okulungileyo (ukwandisa umthamo we-PV ukwandisa inkqubo ye-AC iiyure zomthwalo ogcweleyo) lukhetho oluhle.Uyilo olulungileyo olugqithisileyo lunokunceda zombini inkqubo isondele ekusebenzeni ngokupheleleyo kwaye igcine inkqubo iphantsi kwemeko esempilweni, eyenza utyalo-mali lwakho luxabiseke.
Ubumbeko olucetyiswayo luloluhlobo lulandelayo:
Ngethuba nje umbane ophezulu wesiphaluka ovulekileyo womtya kunye nobuninzi be-DC yangoku ngaphakathi kokunyamezela komatshini, i-inverter inokusebenza ngokudibanisa negridi.
I-1.Ubuninzi be-DC okwangoku yomtya yi-10.86A, engaphantsi kwe-12.5A.
I-2.I-voltage yesiphaluka esiphezulu esivulekileyo somtya ngaphakathi koluhlu lwe-MPPT ye-inverter.
Isishwankathelo
Ngophuculo oluqhubekayo lwamandla emodyuli, abavelisi be-inverter kufuneka baqwalasele ukuhambelana kwee-inverters kunye neemodyuli.Kwixesha elizayo elingekude, iimodyuli ze-500W + PV ezinomgangatho ophezulu wangoku zinokuthi zibe yeyona nto iphambili kwimarike.I-Renac ifezekisa inkqubela phambili ngokuqamba izinto ezintsha kunye netekhnoloji kwaye iya kusungula iimveliso zamva nje ukuhambelana nemodyuli ephezulu yePV yaMandla.
