Imvelaphi:
Ngokwemigaqo-nkqubo ekhoyo ngoku enxulumene nothungelwano lothungelwano lwesizwe, izikhululo zombane eziqhagamshelwe kwigridi yesigaba esinye ngokubanzi azidluli kwi-8 kilowatts, okanye uthungelwano lwegridi olunezigaba ezithathu luyafuneka.Ukongeza, ezinye iindawo zasemaphandleni e-China azinawo amandla amanqanaba amathathu, kwaye zinokufaka isigaba esinye kuphela xa zivuma iprojekthi (xa zifuna ukusebenzisa amandla amanqanaba amathathu, kufuneka zihlawule amashumi amawaka e-yuan ekwakheni. iindleko).Abafaki kunye nabasebenzisi bokugqibela kufuneka baqwalasele iindleko zotyalo-mali.Kuya kunikwa ingqwalaselo ephambili kwakhona ekufakeni iinkqubo zesigaba esinye.
Kwi-2018 nangaphezulu, uRhulumente uya kucacisa ukuphunyezwa kwenkxaso yenkxaso ye-photovoltaic yokuvelisa amandla.Ngelixa uqinisekisa umyinge wotyalo-mali lwezityalo zamandla kunye nenzuzo yabathengi, ukuze kwandiswe umthamo ofakiweyo, iinkqubo zenqanaba elinye le-8KW ziya kuba lolona khetho lulungileyo kwiinkampani ezinkulu zofakelo.
Okwangoku, amandla aphezulu e-inverters yesigaba esisodwa esenziwe ngabavelisi abakhulu be-inverter e-China yi-6-7KW.Xa ufaka izixhobo zamandla ze-8KW, umenzi ngamnye ucebisa ukusetyenziswa kwee-inverters ezimbini ze-5KW + 3KW okanye 4KW + 4KW.Inkqubo.Isicwangciso esinjalo siya kuzisa ingxaki enkulu kwi-installer ngokweendleko zokwakha, ukubeka iliso, kunye nokusebenza kamva kunye nokugcinwa.Elona nqanaba litsha le-8KW inverter yenqanaba elinye le-NCA8K-DS ye-Naton Energy, amandla aphumayo anokufikelela kwi-8KW, anokusombulula ngokuthe ngqo iindawo ezininzi zeentlungu zomsebenzisi.
Oku kulandelayo uXiaobian ukuya kumatshini wombane oqhelekileyo we-8KW njengomzekelo, thatha wonke umntu ukuba aqonde le 8KW yenqanaba elinye inverter inzuzo.Amashumi amathathu anesithandathu i-polycrystalline 265Wp amacandelo aphezulu akhethwa kubathengi.Iiparamitha zobugcisa zamacandelo zimi ngolu hlobo lulandelayo:
Ngokwemodeli yendabuko ye-5KW + 3KW, ii-inverters ezimbini ziyafuneka, apho oomatshini be-3KW baxhunywe kwiimodyuli ze-10, oomatshini be-5KW baxhunyiwe kwiintambo ezimbini, kwaye imodyuli nganye ixhunyiwe kwiimodyuli ze-10.
Jonga kwiiparamitha zombane ze-8KW yekhamera enye ye-Nathon Energy ye-NAC8K-DS (njengoko kubonisiwe kolu luhlu lulandelayo).Amacandelo angama-30 ahlulahlulwe abe yimitya emithathu ukufikelela kwi-inverter:
MPPT1: 10 umtya, 2 umtya ukufikelela
IMPPT2: Iintambo ezili-10, ukufikelela komtya omnye
I-Natong 8KW isiguquli sombane esinenqanaba elinye NAC8K-DS umzobo osisiseko wombane:
Ngokuthelekisa, kwafunyaniswa ukuba ukusebenzisa i-Nato Energy NAC8K-DS inverter kunenzuzo enkulu.
1. Uncedo lweendleko zokwakha:
Isethi yenkqubo ye-8KW ukuba ukusetyenziswa kwe-5KW + 3KW okanye 4KW + 4KW imowudi yokuguqula ixabiso liya kuba malunga ne-5000 +, ngelixa ukusetyenziswa kwe-Natomic NAC8K-DS inverter yesigaba esisodwa, ixabiso lijikeleze i-4000 +.Idityaniswe nentambo ye-AC, intambo ye-DC, ibhokisi yokudibanisa kunye neendleko zokufakela abasebenzi, inkqubo ye-8KW isebenzisa i-Natto energy i-NAC8K-DC 8KW inverter, iseti yeenkqubo inokugcina ubuncinane i-yuan eyi-1,500 kwiindleko.
2. Ukubeka iliso kunye neenzuzo emva kokuthengisa:
Ukusebenzisa ii-inverters ezimbini, abasebenzisi abaninzi abangezongcali abazi ukuba bavelisa njani idatha yokuvelisa amandla, kwaye abazi ngokuthe ngqo ukuba angakanani amandla aveliswayo, kunye nedatha ye-inverter emibini ibangela ubunzima kumfaki ukubala ukuveliswa kwamandla.Nge-inverter ye-Natco NAC8K-DS, idatha yokuvelisa amandla icacile kwaye kulula ukuyiqonda.
I-Natong Energy 8KW yesigaba esinye se-smart PV inverter ikwaxhotyiswe ngenkqubo yokuhlola enamandla.Emva kokubhalisa komsebenzisi, ukusingathwa okuhlakaniphile kunokufezekiswa.Abasebenzisi akufuneki bajonge ubume be-inverter ngokwabo.Emva kokuba i-inverter ibika impazamo, umthengi unokufumana i-othomathikhi ngokukhawuleza kwi-terminal yefowuni yeselula.Kwangelo xesha, abasebenzi benkonzo yasemva kwentengiso yaseNatong nabo baya kufumana okokuqala.Kulwazi olungaphumeleliyo, thatha inyathelo lokuqala lokuqhagamshelana nomthengi ukulungisa ingxaki, ukusombulula ingxaki kunye nokukhusela inzuzo yomthengi.
3. Iingenelo zokwenziwa kombane ngokufanelekileyo:
1) .I-voltage kunye nokuphindaphinda kweegridi ezibuthathaka zasemaphandleni azizinzile.Uqhagamshelo olunxuseneyo lwee-inverters ezininzi lunokubangela ngokulula i-resonance, ukunyuka kombane, kunye nezinye iimeko ezinzima zomthwalo.I-resonance ehambelanayo yoomatshini abaninzi phantsi kweemeko zenethiwekhi ezibuthathaka ziya kubangela ukuba imveliso yangoku ye-inverter i-oscillate, kwaye ingxolo engaqhelekanga ye-inductor iya kutshintsha;iimpawu zemveliso ziya kuchithwa, kwaye i-inverter iya kuba yi-overcurrent kwaye ikhutshwe kakhulu kwinethiwekhi, eya kubangela ukuba i-inverter imise kwaye ichaphazele inzuzo yomthengi.Emva kokuba inkqubo ye-8KW yamkele i-Natto NAC8K-DS, ezi meko ziya kuphuculwa ngokusebenzayo.
2) .Xa kuthelekiswa nemodeli ye-5KW + 3KW okanye i-4KW + 4KW, inkqubo ye-KW isebenzisa ikhebula le-AC enye kuphela kwi-inverter ye-NAC8K-DS, enciphisa ilahleko kunye nokwandisa ukuveliswa kwamandla.
Uqikelelo lwenkqubo yokuvelisa amandla e-8KW (eJinan, kwiPhondo laseShandong njengomzekelo):
Amashumi amathathu anesithandathu amacandelo e-265Wp asebenza ngokufanelekileyo afakwe, kunye nomthamo ofakiweyo we-7.95 KW.Ukusebenza kwenkqubo = 85%.Idatha yokukhanya evela kwi-NASA iboniswe kwitheyibhile elandelayo.Umndilili wokukhanya kwelanga kwiJinan yi-4.28*365=1562.2 iiyure.
Icandelo lehla nge-2.5% kunyaka wokuqala kwaye lehla nge-0.6% ngonyaka ngamnye.Inkqubo ye-8KW ingabalwa kusetyenziswa isiguquli semotor enye eyi-8KW, i-NAC8K-DC, enemveliso yamandla eyongezelekayo emalunga nama-240,000 kWh kwiminyaka engama-25.
ukushwankathela :
Xa ufaka inkqubo ye-8KW, ukusetyenziswa kwe-8KW-inverter yesigaba esinye xa kuthelekiswa nendlela yemveli ye-5KW + 3KW okanye i-4KW + 4KW imodeli ineenzuzo ezinkulu kwiindleko zokwakha kwangaphambili, ukubeka iliso emva kokuthengisa emva kokuthengisa, kunye nemveliso yokuvelisa amandla. .
