Popeza cholinga cha "dual carbon" chinakhazikitsidwa, photovoltaic yogawidwa yakhala ikukondedwa chifukwa cha ubwino wake wochepetsera mpweya wa carbon, zochitika zosiyanasiyana zogwiritsira ntchito komanso kubwerera mosavuta pazachuma.Komabe, ndi kuwonjezeka kwachangu kwa mphamvu yoyikapo, palinso zowawa zambiri pamsika, monga DC high voltage, mbiya mphamvu, ntchito ndi kukonza zovuta ...... Izi zimabweretsa nkhawa za chitetezo ndi kusowa kofunikira kubwerera ku ndalama kwa ogwiritsa ntchito mapeto.
Pazifukwa zowawa pamwambapa, Wo Mai micro inverter imatha kuthetsedwa mosavuta.Tsopano, tikuphatikiza vuto la msika wamakono, kusanthula mozama kwa Wo Mai micro inverse solution, kuti tidziwe.

Kupweteka kwa msika # 1: Chitetezo
M'zaka zaposachedwa, moto wapanyumba wa photovoltaic umachitika pafupipafupi, 80% womwe umayamba chifukwa cha DC arc chifukwa chamagetsi amtundu wa DC.Komanso, ma photovoltaic systems nthawi zambiri amaikidwa padenga la nyumba kapena mafakitale.Moto kapena kuphulika zikachitika, zimabweretsa kuwonongeka kwa katundu kosaneneka komanso kuyika miyoyo pachiswe.
Kuphatikiza apo, pali mazana kapena masauzande a ma volt a DC munjira yoyaka moto.Ngati ozimitsa moto athamangira kukapulumutsa, zingakhale ndi zotsatira zomvetsa chisoni.Zotsatira zake, oyankha koyamba nthawi zambiri amayenera kudikirira kuti mbewuyo iwotchere kwathunthu asanayambe ntchito yawo, zomwe nthawi zambiri zimabweretsa kuchedwa kwakukulu kwa ntchito zozimitsa moto.

Chitetezo chochepa chamagetsi, palibe chowopsa chamoto komanso chiwopsezo chamagetsi
Hemai yaying'ono inverter yolumikizidwa ndi dongosolo la photovoltaic mofananira, kupangitsa mbali ya DC ya dongosolo kukhala yokhazikika pafupifupi 40V otsika voteji, kuchokera muzu kuti athetse zoopsa zamoto ndi kuwopsa kwamagetsi.Sitiyenera kuda nkhawa ndi moto wa DC arc pamalo opangira magetsi ocheperako.
Ngakhale makina a inverter ang'onoang'ono ali ndi vuto ladzidzidzi chifukwa cha zinthu zakunja, atatha kutseka dongosolo, oyankha oyambirira sangakumane ndi chiopsezo cha magetsi chifukwa palibe DC high voltage mu PV plant.

Kupweteka kwa msika 2: zotsatira za mbiya
Gulu lililonse la photovoltaic lili ndi mawonekedwe osiyanasiyana, monga panopa, magetsi ndi malo abwino ogwiritsira ntchito.Kusagwirizana kumeneku kudzawonekera kwambiri pamene makina a photovoltaic amagwiritsidwa ntchito panja kwa nthawi yaitali ndi zaka mwachibadwa.Makhalidwe opangira mphamvu zamagetsi amtundu wa photovoltaic amagwirizana kwambiri ndi "mgolo wamatabwa" : dongosolo la photovoltaic lachikhalidwe limapangidwa motsatizana, ndipo kutulutsa mphamvu zonse zamagulu angapo a photovoltaic kumadalira kwambiri kutulutsa kwa photovoltaic yofooka kwambiri. gulu mu mndandanda, kutanthauza kuti "ofooka" ndithudi kukoka gulu pansi ndi zimakhudza mphamvu kupanga mphamvu.

Ukadaulo wamtundu wa MPPT umachotsa mbiya
Poona "cask effect", Wo Mai micro reverse mankhwala.Wowongolera wake wa MPPT amatsata mphamvu yayikulu kwambiri pagawo lililonse la PV padera.Ngakhale gawo limodzi la PV silikuyenda bwino, silingakhudze ma module ena a PV.Mwachitsanzo, mu dongosolo lonse la photovoltaic, ngati chigawocho chawonongeka kapena kutsekedwa, wolamulira wamkulu wotsatira mphamvu ya zigawo zina adzapitirizabe kusunga mphamvu zawo zogwira ntchito.
