Selemong sena, ketsahalo ea El Niño e ka 'na ea etsahala, kapa lehlabula le chesang ka ho fetisisa historing le tla qala, e leng se tla tlisa mathata a matla ho limela tsa matla a photovoltaic.
1.1 Phello ea mocheso o phahameng ho likarolo
Mocheso o feteletseng o tla fokotsa ts'ebetso le bophelo ba likarolo, tse kang li-inductors, electrolytic capacitor, li-module tsa matla, joalo-joalo.
Inductance:Ka mocheso o phahameng, inductance e bonolo ho tlala, 'me inductance e tletseng e tla fokotseha, e leng se etsang hore ho be le keketseho ea tlhōrō ea tlhōrō ea ts'ebetso ea hona joale, le tšenyo ea sesebelisoa sa matla ka lebaka la ho feta hona joale.
Capacitor:Bakeng sa li-capacitor tsa electrolytic, tebello ea bophelo ea li-electrolytic capacitor e fokotsoa ka halofo ha mocheso oa tikoloho o nyoloha ka 10°C.Aluminium electrolytic capacitor ka kakaretso e sebelisa mocheso o fapaneng oa -25~+105°C, 'me li-capacitor tsa filimi ka kakaretso li sebelisa mocheso o fapaneng oa -40~+105°C.Ka hona, li-inverters tse nyane hangata li sebelisa li-capacitor tsa lifilimi ho ntlafatsa ho ikamahanya le maemo a li-inverters ho mocheso o phahameng.
Bophelo ba li-capacitor ka mocheso o fapaneng
Module ea matla:Ha mocheso o phahame, mocheso oa mateano oa chip o phahame ha mochine oa matla o sebetsa, o etsang hore mojule o be le khatello e phahameng ea mocheso le ho khutsufatsa haholo bophelo ba tšebeletso.Hang ha mocheso o feta moeli oa mocheso oa mateano, o tla baka ho senyeha ha mocheso oa mojule.
1.2 Mehato ea ho Fetola Mocheso oa Inverter
Inverter e ka sebetsa ka ntle ho 45 ° C kapa mocheso o phahameng.Moqapi oa ho senya mocheso oa inverter ke mokhoa oa bohlokoa oa ho netefatsa ts'ebetso e tsitsitseng, e sireletsehileng le e ka tšeptjoang ea karolo ka 'ngoe ea elektronike sehlahisoa ka har'a mocheso o sebetsang.Sebaka sa mahloriso a mocheso oa inverter ke inductor ea boost, inverter inductor, le module ea IGBT, 'me mocheso o qhaloa ka fan ea ka ntle le teba ea mocheso o ka morao.Se latelang ke mocheso o fokolang oa GW50KS-MT:
Ho phahama ha mocheso oa inverter le ho theoha ha moroalo
1.3 Leano la kaho le khahlanong le mocheso o phahameng
Marulelong a indasteri, hangata mocheso o phahame ho feta oa fatše.E le ho thibela inverter hore e se ke ea pepeseha letsatsing le tobileng, hangata inverter e kenngoa sebakeng se nang le moriti kapa ho eketsoa ka holim'a moferefere.Hoa lokela ho hlokomeloa hore sebaka sa ts'ebetso le tlhokomelo se lokela ho bolokoa sebakeng seo fan ea inverter e kenang ho sona le ho tsoa moeeng le fan ea ka ntle.Se latelang ke inverter e nang le moea o kenang le ho tsoa ka letsohong le letšehali le le letona.Hoa hlokahala ho boloka sebaka se lekaneng mahlakoreng ka bobeli a inverter, 'me u boloke sebaka se loketseng pakeng tsa visor ea letsatsi le top of the inverter.

Lipula tsa lialuma le lifefo lehlabula.
2.1 Mehato ea Tšireletso ea Lehalima le Pula ea Inverter
Mehato ea ts'ireletso ea lehalima ea inverter:Mahlakore a AC le DC a inverter a na le lisebelisoa tse phahameng tsa tšireletso ea lehalima, 'me mabitso a omileng a na le li-alarm tsa tšireletso ea lehalima, tse loketseng ka morao ho tseba boemo bo itseng ba tšireletso ea lehalima.
Mehato e thibelang pula ea inverter le e thibelang kutu:Inverter e amohela boemo bo phahameng ba ts'ireletso ea IP66 le boemo ba C4&C5 ba anti-corrosion ho etsa bonnete ba hore mochini o tsoela pele ho sebetsa tlas'a pula ea litloebelele.
Khokahano ea bohata ea sehokelo sa photovoltaic, ho kenella ha metsi ka mor'a hore thapo e senyehe, e leng se bakang potoloho e khuts'oane ka lehlakoreng la DC kapa ho lutla fatše, ho etsa hore inverter e emise.Ka hona, ts'ebetso ea ho lemoha arc ea DC ea inverter le eona e bohlokoa haholo.
2.2 Leano le akaretsang la tšireletso ea lehalima (kaho).
Etsa mosebetsi o motle oa tsamaiso ea lefatše, ho kenyelletsa le li-terminals tsa likarolo le li-inverters.
Mehato ea tšireletso ea lehalima holim'a phanele ea letsatsi le inverter
Lipula tsa lehlabula le tsona li ka etsa hore lehola le hole le ho etsa moriti oa likarolo.Ha metsi a pula a hlatsoa likaroloana, ho bonolo ho etsa hore lerōle le bokelle mathōkong a likaroloana, tse tla ama mosebetsi o latelang oa ho hloekisa.
Etsa mosebetsi o motle oa ho hlahloba tsamaiso, kamehla hlahloba maemo a ho kenya le ho thibela metsi a li-connectors tsa photovoltaic le lithapo, sheba hore na lithapo li kolobisitsoe ka mokhoa o itseng metsing a pula, le hore na ho na le botsofali le mapetsong a sheath ea cable insulation.
Ho hlahisa matla a photovoltaic ke ho hlahisa matla a leholimo a leholimo kaofela.Mocheso o phahameng le lialuma lehlabula li tlisitse mathata a maholo ts'ebetsong le tlhokomelong ea limela tsa matla a photovoltaic.Ka ho kopanya mochine o kenang motlakase le moralo oa kakaretso oa setsi sa motlakase, Xiaogu o fana ka litlhahiso mabapi le kaho, ts'ebetso le tlhokomelo, 'me o tšepa ho thusa bohle.
