Mbiri:
Malinga ndi ndondomeko zomwe zilipo panopa zokhudzana ndi gridi ya dziko, malo opangira magetsi omwe amalumikizidwa ndi gridi imodzi nthawi zambiri sadutsa ma kilowati 8, kapena magawo atatu olumikizidwa ndi grid amafunikira. Kuphatikiza apo, madera ena akumidzi ku China alibe mphamvu zamagawo atatu, ndipo amatha kukhazikitsa gawo limodzi akavomereza ntchitoyi (pamene akufuna kugwiritsa ntchito mphamvu zamagawo atatu, ayenera kulipira ma yuan masauzande ambiri pomanga. mtengo). Okhazikitsa ndi omaliza akuyenera kuganizira za mtengo wandalama. Chofunika kwambiri chidzaperekedwanso pakuyika machitidwe a gawo limodzi.
Mu 2018 ndi mtsogolo, Boma lidzafotokozera momveka bwino kukhazikitsidwa kwa subsidy ya chithandizo chamagetsi cha photovoltaic. Kuwonetsetsa kuchuluka kwa ndalama zopangira magetsi komanso phindu lamakasitomala, kuti muwonjezere mphamvu zomwe zakhazikitsidwa, makina agawo limodzi a 8KW adzakhala chisankho chabwino kwambiri kwamakampani akuluakulu oyika.
Pakadali pano, mphamvu yayikulu ya ma inverters agawo limodzi omwe amayambitsidwa ndi opanga ma inverter akuluakulu ku China ndi 6-7KW. Mukayika magetsi a 8KW, wopanga aliyense amalimbikitsa kugwiritsa ntchito ma inverters awiri a 5KW + 3KW kapena 4KW + 4KW. Pulogalamu. Ndondomeko yotereyi idzabweretsa mavuto ambiri kwa oyikapo potengera ndalama zomanga, kuyang'anira, ndikugwira ntchito ndi kukonza pambuyo pake. The 8KW single-phase inverter NCA8K-DS ya Naton Energy, mphamvu yotulutsa imatha kufika 8KW, imatha kuthana ndi zowawa zingapo za wosuta.
Zotsatira zotsatirazi za Xiaobian ku makina opangira magetsi a 8KW monga chitsanzo, tengerani aliyense kuti amvetsetse mwayi wosinthira gawo limodzi wa 8KW. Magawo makumi atatu ndi asanu ndi limodzi a polycrystalline 265Wp apamwamba kwambiri amasankhidwa kwa makasitomala. The luso magawo a zigawo zikuluzikulu ndi motere:
Malinga ndi mtundu wachikhalidwe wa 5KW + 3KW, ma inverters awiri amafunikira, pomwe makina a 3KW amalumikizidwa ndi ma module a 10, makina a 5KW amalumikizidwa ndi zingwe ziwiri, ndipo gawo lililonse limalumikizidwa ndi ma module a 10.
Onani magawo amagetsi a Nathon Energy's 8KW kamera imodzi NAC8K-DS (monga zikuwonekera patebulo lotsatira). Zigawo 30 zimagawidwa m'zingwe zitatu kuti mupeze inverter:
MPPT1: 10 zingwe, 2 zingwe kupeza
MPPT2: zingwe 10, 1 chingwe chofikira
Natong 8KW single-phase inverter NAC8K-DS primary magetsi chithunzi:
Poyerekeza, zidapezeka kuti kugwiritsa ntchito Nato Energy NAC8K-DS inverter kuli ndi zabwino zambiri.
1. Mtengo wamtengo womanga:
A seti ya 8KW dongosolo ngati ntchito 5KW + 3KW kapena 4KW + 4KW mode inverter mtengo adzakhala mozungulira 5000 +, pamene ntchito Natomic NAC8K-DS single-gawo inverter, mtengo ndi kuzungulira 4000 +. Kuphatikizidwa ndi chingwe cha AC, chingwe cha DC, bokosi lophatikizira ndikuyika ndalama zogwirira ntchito, makina a 8KW amagwiritsa ntchito inverter ya Natto energy NAC8K-DC 8KW, makina angapo amatha kupulumutsa pafupifupi yuan 1,500 pamtengo.
2. Ubwino wowunika ndi kugulitsa pambuyo pake:
Pogwiritsa ntchito ma inverters awiri, ogwiritsa ntchito ambiri omwe si akatswiri sakudziwa momwe angapangire deta yopangira mphamvu, ndipo sadziwa momwe mphamvu imapangidwira, ndipo deta ya inverter iwiriyi imayambitsanso zovuta kuti woyikirayo awerengere mphamvu yamagetsi. Ndi inverter ya Natco NAC8K-DS, deta yopangira mphamvu ndi yomveka komanso yosavuta kumva.
Natong Energy 8KW single-phase smart PV inverter ilinso ndi njira yamphamvu yowunikira. Wogwiritsa ntchito akalembetsa, kuchititsa mwanzeru kumatha kuchitika. Ogwiritsa safunikira kuyang'ana momwe inverter ilili pawokha. Pambuyo pa inverter ikunena cholakwika, kasitomala atha kulandira chidziwitso chodziwikiratu pagawo la foni yam'manja. Nthawi yomweyo, ogwira ntchito ku Natong pambuyo pogulitsa alandilanso koyamba. Kuti mudziwe zolephera, yesetsani kulankhulana ndi kasitomala kuti muthetse mavuto, kuthetsa vutoli ndikuteteza phindu la kasitomala.
3. Ubwino wopangira mphamvu zamagetsi:
1) .Kuthamanga kwamagetsi ndi mafupipafupi a ma grids ofooka akumidzi sali okhazikika. Kulumikizana kofananira kwa ma inverters angapo kumatha kuyambitsa ma resonance, kukwera kwamagetsi, ndi zovuta zina zolemetsa. Kufanana kofanana kwa makina angapo pansi pazikhalidwe zofooka za netiweki kumapangitsa kuti inverter ituluke, ndipo phokoso losazolowereka la inductor lidzasintha; mawonekedwe otulutsa adzasokonekera, ndipo inverter idzakhala yopitilira muyeso ndikuchotsa kwambiri pa intaneti, zomwe zidzapangitsa kuti inverter ayimitse ndikukhudza phindu la kasitomala. Dongosolo la 8KW litatenga Natto NAC8K-DS, izi zisintha bwino.
2) .Poyerekeza ndi zitsanzo za 5KW + 3KW kapena 4KW + 4KW, dongosolo la KW limagwiritsa ntchito chingwe chimodzi chokha cha AC kwa inverter ya NAC8K-DS, yomwe imachepetsa kutayika ndikuwonjezera mphamvu zamagetsi.
Kuyerekeza kwamphamvu kwa 8KW system (ku Jinan, Province la Shandong monga chitsanzo):
Zida makumi atatu ndi zisanu ndi chimodzi za 265Wp zogwira mtima kwambiri zidayikidwa, zokhala ndi mphamvu zokwanira 7.95 KW. Kuchita bwino kwadongosolo = 85%. Deta yopepuka yochokera ku NASA ikuwonetsedwa patebulo lotsatirali. Kuwala kwa dzuwa tsiku lililonse ku Jinan ndi 4.28*365=1562.2 maola.
Gawoli limatsika ndi 2.5% mchaka choyamba kenako limatsika ndi 0.6% chaka chilichonse. Dongosolo la 8KW litha kuwerengedwa pogwiritsa ntchito inverter ya 8KW single-motor, NAC8K-DC, yokhala ndi mphamvu zochulukirapo pafupifupi 240,000 kWh m'zaka 25.
powombetsa mkota :
Mukayika makina a 8KW, kugwiritsa ntchito inverter ya 8KW imodzi-gawo poyerekeza ndi njira yanthawi zonse ya 5KW + 3KW kapena 4KW + 4KW ili ndi zabwino zambiri pamtengo woyambira womanga, kuwunika pambuyo pakugulitsa, komanso kutulutsa mphamvu. .
