Ingemuva:
Ngokusho kwezinqubomgomo ezihlobene negridi ezihlobene negridi, iziteshi zamandla ezixhunywe esigabeni esisodwa ngokuvamile azidluli ama-kilowatts ayi-8, noma amanethiwekhi axhumeke amagridi amathathu ayadingeka. Ngaphezu kwalokho, ezinye izindawo zasemakhaya eChina azinawo amandla ezigaba ezintathu, futhi zingafaka kuphela isigaba esisodwa lapho zivuma iphrojekthi (lapho zifuna ukusebenzisa amandla ezigaba ezintathu, kufanele zikhokhe amashumi ezinkulungwane zeYuan ezindlekweni zokwakha). Abasebenzisi nabasebenzisi bokugcina kufanele bacabangele izindleko zokutshala imali. Okusemqoka kuzophinde kunikezwe ekufaka amasistimu wesigaba esisodwa.
Ngo-2018 nangaphambili, uMbuso uzokwenza kwacaca ukwenziwa kwexhaswa koxhaso lwe-Photovoltaic amandla okusekelwa koxhaso. Ngenkathi uqinisekisa inani lokutshala imali yamandla kanye nenzuzo yamakhasimende, ukuze kwandise umthamo ofakiwe, izinhlelo ze-8kW eyodwa-Phase zizoba yisinqumo esihle kakhulu sezinkampani zokufaka ezinkulu.
Njengamanje, amandla aphezulu ama-inverters wesigaba esisodwa angeniswa ngabakhiqizi abakhulu be-Inverter eChina ngu-6-7kw. Lapho ufaka izitshalo zamandla ze-8kW, umenzi ngamunye utusa ukusetshenziswa kwama-inverters amabili we-5kW + 3KW noma i-4KW + 4KW. Uhlelo. Uhlelo olunjalo luzoletha izinkinga eziningi kulokhu okufakwa ngokwezindleko zokwakha, ukuqapha, kanye nokusebenza kwakamuva nokulungisa. I-Inverter entsha ye-8kW eyodwa yesigaba se-NCA8K-DS ye-Naton Energy, amandla okukhipha angafinyelela ama-8kw, angaxazulula ngqo amaphuzu ambalwa wezinhlungu zomsebenzisi.
Le xiaobian elandelayo esitshalweni esijwayelekile se-8kW Power isibonelo, thatha wonke umuntu ukuthi aqonde le nzuzo ye-8kW eyodwa ye-Inverter Inverter. Izingxenye ezingamashumi amathathu nesithupha polycrystalline 265WP akhethiwe akhethiwe kumakhasimende. Amapharamitha obuchwepheshe wezakhi anjengokulandelayo:
Ngokusho kwemodeli yendabuko ye-5KW + 3KW, ama-inverter amabili ayadingeka, lapho imishini ye-3KW ixhumeke kumamojula ayi-10, imishini engu-5KW ixhumeke ezintanjeni ezimbili, futhi imodyuli ngayinye ixhunywe kumamojula ayi-10.
Bheka amapharamitha kagesi weNathon Energy's 8kW Energy-camera-camera-camera-ds (njengoba kukhonjisiwe etafuleni elilandelayo). Izakhi ezingama-30 zihlukaniswe izintambo ezintathu ukufinyelela i-inverter:
I-MPPT1: String 10, ukufinyelela kwentambo 2
I-MPPT2: Izintambo eziyi-10, ukufinyelela okungu-1 string
I-Natong 8KW eyodwa-isigaba sodwa-isigaba se-NAC8K-DS Primary Electrical Diagam:
Ngokuqhathanisa, kwatholakala ukuthi ukusebenzisa i-Nato Energy Energy Nac8k-DS Inverter inezinzuzo ezinhle.
1. Inzuzo yezindleko zokwakha:
Iqoqo lesistimu ye-8kw uma ukusetshenziswa kwe-5kkw + 3kw noma imodi ye-4KW + 4KW yemodi ye-Inverter Inverter kuzoba cishe ngo-5000 +, ngenkathi kusetshenziswa i-National NATOMI CLASSIGNER Inverter, imali ecishe ibe ngu-4000 +. Kuhlanganiswe nekhebula le-AC, ikhebula le-DC, ibhokisi le-combiner nezindleko zabasebenzi, uhlelo lwe-8kw lusebenzisa i-natto energy nac8k-dc 8kw inverter, iqoqo lezinhlelo zingasindisa okungenani ama-1,500 yuan ngezindleko.
2. Ukuqapha nangemva kokuthengisa:
Kusetshenziswa ama-inverters amabili, abasebenzisi abaningi abangewona ama-oppolul abangazi ukuthi bayikhiphe kanjani idatha yokukhiqiza amandla, futhi abazi kahle ukuthi malini akhiqizwa, kanti nemininingwane emibili ye-inverter nayo ibangela ubunzima bokubalwa isifaki. Nge-NATCO NAC8K-DS inverter, idatha yesizukulwane samandla icacile futhi kulula ukuyiqonda.
I-Natong Energy 8KW eyodwa-isigaba sodwa-isigaba Smart PV inverter nayo ifakwe uhlelo lokuqapha olunamandla. Ngemuva kokubhalisa komsebenzisi, ukusingathwa okuhle kungabonakala. Abasebenzisi abadingi ukubheka isimo se-inverter ngokwabo. Ngemuva kokuthi i-Inverter ibike iphutha, ikhasimende lingathola ngokushesha okuzenzakalelayo kwi-terminal yefoni ephathekayo. Ngasikhathi sinye, abasebenzi baseNatong ngemuva kokuthengisa abathengisi bazothola okokuqala. Ulwazi lokwehluleka, thatha isinyathelo kuqala ukuxhumana nekhasimende ukuxazulula inkinga, ukuxazulula inkinga futhi uvikele inzuzo yekhasimende.
3. Izinzuzo zokusebenza kahle kwamandla:
1) Ukuxhumana okuhambisanayo kwama-inverterters amaningi kungadala kalula ukubabaza, ukukhuphuka kwamandla kagesi, nezinye izimo eziyinkimbinkimbi kakhulu zomthwalo. Ukubuyiselwa okuhambisanayo kwemishini eminingi ngaphansi kwezimo zenethiwekhi ezibuthakathaka kuzodala ukuthi umphumela wamanje we-inverter ku-oscillate, futhi umsindo ongafanele we-inductor uzoshintsha; Izici zokuphuma zizokonakala, futhi i-inverter izoba ngaphezulu futhi isuka kwinethiwekhi, ezokwenza inserter imeme futhi ihoxise inzuzo yekhasimende. Ngemuva kokuthi uhlelo lwe-8kw lusebenzisa i-Natto NAC8K-DS, lezi zimo zizothuthukiswa ngempumelelo.
2)
Isilinganiso sokukhiqiza amandla se-8kw (eJinan, esiFundazweni saseShandong njengesibonelo):
Kufakwe izingxenye ezingamashumi amathathu nesithupha Ukusebenza kahle kwesistimu = 85%. Imininingwane ekhanyayo ethathwe ku-NASA ikhonjiswe etafuleni elilandelayo. Isikhathi esijwayelekile sokukhanya kwelanga eJinan ngu-4.28 * 365 = 1562.2 amahora.
Ingxenye ihambisa ngo-2,5% ngonyaka wokuqala bese yehla ngo-0.6% unyaka ngamunye. Uhlelo lwe-8kw lungabalwa kusetshenziswa i-inverter ye-8kW eyodwa-motor, i-NAC8K-DC, ngesizukulwane samandla okuqongelayo saba cishe iminyaka engama-240,000 eminyakeni engama-25.
ngamafuphi :
Lapho ufaka uhlelo lwe-8kw, ukusetshenziswa kwe-8kW eyodwa yesigaba se-Inverter uma kuqhathaniswa nendlela yendabuko ye-5KW + 3KW + 4KW inezinzuzo ezinhle kakhulu kwizindleko zokwakha zangemva kokuthengisa, kanye nesivuno sokukhiqiza amandla.
