Ingemuva:
Ngokwezinqubomgomo zamanje ezihlobene negridi kazwelonke, iziteshi zamandla ezixhunywe kugridi yesigaba esisodwa ngokuvamile azidluli ama-kilowatts angu-8, noma kudingeka amanethiwekhi axhunywe kugridi ezigaba ezintathu.Ngaphezu kwalokho, ezinye izindawo zasemaphandleni e-China azinawo amandla ezigaba ezintathu, futhi zingafaka isigaba esisodwa kuphela lapho zigunyaza iphrojekthi (uma zifuna ukusebenzisa amandla ezigaba ezintathu, kufanele zikhokhe amashumi ezinkulungwane zama-yuan ekwakheni. izindleko).Abafaki nabasebenzisi bokugcina kufanele bacabangele izindleko zokutshala imali.Kuzobekwa phambili futhi ekufakeni amasistimu esigaba esisodwa.
Ku-2018 nangaphezulu, uMbuso uzocacisa ukuqaliswa koxhaso lwezibonelelo zokukhiqiza amandla e-photovoltaic.Ngenkathi kuqinisekiswa izinga lokutshalwa kwezimali kwezitshalo zikagesi kanye nenzuzo yamakhasimende, ukuze kwandiswe umthamo ofakiwe, amasistimu wesigaba esisodwa esingu-8KW azoba yisinqumo esingcono kakhulu ezinkampanini ezinkulu zokufaka.
Njengamanje, amandla aphezulu ama-inverter esigaba esisodwa esethulwe abakhiqizi abakhulu be-inverter e-China yi-6-7KW.Uma ufaka izitshalo zamandla angu-8KW, umenzi ngamunye uncoma ukusetshenziswa kwama-inverter amabili angu-5KW+3KW noma 4KW+4KW.Uhlelo.Uhlelo olunjalo luzoletha izinkinga eziningi kumfakisi ngokuphathelene nezindleko zokwakha, ukuqapha, nokusebenza nokugcinwa kamuva.I-inverter entsha ye-8KW yesigaba esisodwa ye-NCA8K-DS ye-Naton Energy, amandla okukhiphayo angafinyelela ku-8KW, ingaxazulula ngokuqondile amaphuzu ambalwa obuhlungu omsebenzisi.
I-Xiaobian elandelayo eya esikhungweni samandla esijwayelekile esingu-8KW njengesibonelo, thatha wonke umuntu ukuthi aqonde le nzuzo ye-inverter yesigaba esisodwa engu-8KW.Izingxenye ezingamashumi amathathu nesithupha ze-polycrystalline 265Wp ezisebenza kahle kakhulu zikhethelwa amakhasimende.Imingcele yezobuchwepheshe yezingxenye imi kanje:
Ngokwemodeli yendabuko ye-5KW + 3KW, ama-inverter amabili ayadingeka, lapho imishini engu-3KW ixhunywe inani lamamojula angu-10, imishini ye-5KW ixhunywe kuzintambo ezimbili, futhi imojula ngayinye ixhunywe kumamojula angu-10.
Bheka amapharamitha kagesi wekhamera eyodwa ye-Nathon Energy's 8KW NAC8K-DS (njengoba kukhonjisiwe kuthebula elilandelayo).Izingxenye ze-30 zihlukaniswe ngezintambo ezintathu ukuze zifinyelele i-inverter:
I-MPPT1: Iyunithi yezinhlamvu engu-10, ukufinyelela kwezintambo ezingu-2
I-MPPT2: Izintambo ezingu-10, ukufinyelela kweyunithi yezinhlamvu engu-1
I-Natong 8KW inverter yesigaba esisodwa se-NAC8K-DS umdwebo kagesi oyinhloko:
Ngokuqhathanisa, kutholwe ukuthi ukusebenzisa isiguquli se-Nato Energy NAC8K-DS kunezinzuzo ezinhle.
1. Inzuzo yezindleko zokwakha:
Isethi yesistimu engu-8KW uma ukusetshenziswa kwezindleko ze-inverter yemodi engu-5KW +3KW noma 4KW +4KW kuzoba cishe ku-5000 +, kuyilapho ukusetshenziswa kwesiguquli sesigaba esisodwa se-Natomic NAC8K-DS, izindleko zingaba ngu-4000 +.Ngokuhambisana nekhebula le-AC, ikhebula le-DC, ibhokisi lesihlanganisi nezindleko zokusebenza zokufaka, uhlelo lwe-8KW lusebenzisa inverter ye-Natto energy NAC8K-DC 8KW, isethi yamasistimu ingonga okungenani u-1,500 yuan ngezindleko.
2. Ukuqapha kanye nezinzuzo zangemuva kokuthengisa:
Ngokusebenzisa ama-inverter amabili, abasebenzisi abaningi okungebona abangochwepheshe abazi ukuthi bangakhiqiza kanjani idatha yokuphehla amandla, futhi abazi kahle ukuthi angakanani amandla akhiqizwayo, kanye nedatha ye-inverter emibili nayo ibangela ubunzima ukuze isifaki sibale ukukhiqizwa kwamandla.Nge-inverter ye-Natco NAC8K-DS, idatha yokukhiqiza amandla icacile futhi kulula ukuyiqonda.
I-Natong Energy 8KW i-smart PV inverter yesigaba esisodwa nayo ifakwe uhlelo olunamandla lokuqapha.Ngemuva kokubhalisa komsebenzisi, ukusingathwa okuhlakaniphile kungabonakala.Abasebenzisi abadingi ukuhlola isimo se-inverter bebodwa.Ngemuva kokuthi isiguquli sibike iphutha, ikhasimende lingathola ukwaziswa okuzenzakalelayo kutheminali yomakhalekhukhwini.Ngasikhathi sinye, abasebenzi baseNatong abasebenza ngemuva kokuthengisa bazothola okokuqala.Olwazini lokwehluleka, thatha isinyathelo sokuxhumana nekhasimende ukuze uxazulule inkinga, uxazulule inkinga futhi uvikele inzuzo yekhasimende.
3. Izinzuzo zokusebenza kahle kokukhiqizwa kwamandla:
1).I-voltage kanye nemvamisa yamagridi abuthaka asemaphandleni azinzile.Ukuxhumeka okuhambisanayo kwama-inverter amaningi kungabangela kalula i-resonance, ukunyuka kwe-voltage, nezinye izimo zokulayisha eziyinkimbinkimbi.I-resonance ehambisanayo yemishini eminingi ngaphansi kwezimo zenethiwekhi ezibuthakathaka izobangela ukukhishwa kwamanje kwe-inverter ku-oscillate, futhi umsindo ongavamile we-inductor uzoshintsha;izici zokukhipha zizowohloka, futhi i-inverter izoba ngokweqile futhi ivale kakhulu inethiwekhi, okuzokwenza ukuthi i-inverter ime futhi ithinte inzuzo yekhasimende.Ngemuva kokuthi uhlelo lwe-8KW lwamukele i-Natto NAC8K-DS, lezi zimo zizothuthukiswa ngempumelelo.
2).Uma kuqhathaniswa namamodeli angu-5KW+3KW noma 4KW+4KW, uhlelo lwe-KW lusebenzisa intambo eyodwa kuphela ye-AC ku-inverter ye-NAC8K-DS, enciphisa ukulahlekelwa futhi ikhulise ukukhiqizwa kwamandla.
Isilinganiso sokuphehla amandla ohlelo lwe-8KW (eJinan, esifundazweni saseShandong njengesibonelo):
Izingxenye ezingamashumi amathathu nesithupha ze-265Wp ezisebenza kahle kakhulu, ezinamandla afakiwe angu-7.95 KW.Ukusebenza kahle kwesistimu = 85%.Idatha ekhanyayo etholakala ku-NASA ikhonjiswe kuthebula elilandelayo.Isilinganiso sobude besikhathi sokukhanya kwelanga nsuku zonke eJinan singamahora angu-4.28*365=1562.2.
Ingxenye yehla ngo-2.5% ngonyaka wokuqala bese yehla ngo-0.6% unyaka ngamunye.Uhlelo lwe-8KW lungabalwa kusetshenziswa isiguquli semotho eyodwa esingu-8KW, i-NAC8K-DC, enamandla okukhiqiza amandla acishe abe ngu-240,000 kWh eminyakeni engama-25.
ngamafuphi :
Lapho ufaka uhlelo lwe-8KW, ukusetshenziswa kwesiguquli sesigaba esisodwa esingu-8KW uma kuqhathaniswa nendlela evamile yemodeli engu-5KW+3KW noma 4KW+4KW kunezinzuzo ezinhle ezindlekweni zokuqala zokwakha, ukuqapha ngemuva kokuthengisa ngemva kokuthengisa, kanye nesivuno sokukhiqiza amandla. .
