Muzhizha, photovoltaic simba zvidyarwa zvinokanganiswa nemamiriro ekunze akaoma senge tembiricha yepamusoro, mheni uye mvura inonaya.Nzira yekuvandudza sei kugadzikana kwe photovoltaic simba zvidyarwa kubva pakuona kwe inverter dhizaini, yakazara simba rekudyara dhizaini uye kuvaka?

Gore rino, chiitiko cheEl Niño chinogona kuitika, kana zhizha rinopisa zvikuru munhoroondo richaunza, izvo zvichaunza mamwe matambudziko akaoma kune photovoltaic magetsi emagetsi.
1.1 Mhedzisiro yekushisa kwepamusoro pane zvikamu
Tembiricha yakawandisa inoderedza kuita uye hupenyu hwezvikamu, senge inductors, electrolytic capacitors, magetsi module, nezvimwe.
Inductance:Pakupisa kwepamusoro, iyo inductance iri nyore kuzara, uye inductance yakazara ichaderera, zvichiita kuti kuwedzerwa kwepamusoro-soro yekushanda ikozvino, uye kukanganisa kwechigadziro chemagetsi nekuda kwepamusoro-ikozvino.
Capacitor:Kuma electrolytic capacitor, hupenyu hwema electrolytic capacitor hunodzikiswa nehafu apo tembiricha ye ambient inokwira ne10°C.Aluminium electrolytic capacitors kazhinji inoshandisa tembiricha ye -25~+105°C, uye mafirimu capacitor anowanzo shandisa tembiricha ye -40~+105°C.Naizvozvo, madiki inverters anowanzo shandisa firimu capacitors kuvandudza kuchinjika kwema inverters kune yakanyanya tembiricha.
Upenyu hwema capacitors pakupisa kwakasiyana
Power module:Iyo yakakwira tembiricha, iyo inokwidza tembiricha yekusangana kweiyo chip kana module yemagetsi iri kushanda, izvo zvinoita kuti module itakure kushushikana kwakanyanya kwekushisa uye kupfupisa zvakanyanya hupenyu hwesevhisi.Kamwe tembiricha yadarika iyo junction tembiricha muganho, zvinokonzeresa kuparara kweiyo module.
1.2 Inverter Heat Dissipation Matanho
Iyo inverter inogona kushanda kunze pa45 ° C kana kupfuura tembiricha.Iyo yekupisa kupisa dhizaini ye inverter inzira yakakosha yekuvimbisa kugadzikana, yakachengeteka uye yakavimbika kushanda kwega yega chikamu chemagetsi mune chigadzirwa mukati mekushisa kwekushanda.Iyo tembiricha yekumisikidza nzvimbo yeiyo inverter ndiyo inosimudzira inductor, inverter inductor, uye IGBT module, uye kupisa kunobviswa kuburikidza nekunze feni uye kumashure kupisa sink.Inotevera tembiricha inodzikira curve yeGW50KS-MT:
Inverter tembiricha inokwira uye inodonha mutoro curve
1.3 Kuvaka anti-yepamusoro tembiricha zano
Padenga remaindasitiri, tembiricha inowanzokwira kupfuura iri pasi.Kuti udzivise iyo inverter kuti isaonekwe kune yakananga zuva, iyo inverter inowanzoiswa munzvimbo ine mumvuri kana baffle inowedzerwa pamusoro peiyo inverter.Izvo zvinofanirwa kucherechedzwa kuti nzvimbo yekushanda nekugadzirisa inofanira kuchengetwa panzvimbo iyo inverter fan inopinda uye inobuda mumhepo uye kunze fan.Izvi zvinotevera inverter ine kuruboshwe uye kurudyi mhepo inotora uye kubuda.Izvo zvinodikanwa kuchengetedza nzvimbo yakakwana pamativi ese eiyo inverter, uye kuchengetedza chinhambwe chakakodzera pakati pezuva visor uye pamusoro peiyo inverter.

Mabhanan'ana nemadutu emvura muzhizha.
2.1 Inverter Mheni uye Matanho ekudzivirira kwemvura
Inverter mheni kudzivirira matanho:Iyo AC uye DC mativi eiyo inverter akashongedzerwa nepamusoro-level ekudzivirira mheni zvishandiso, uye iwo akaoma anobatika ane mheni yekudzivirira alarm uploads, izvo zviri nyore kuti kumashure kuziva chaiyo mamiriro ekudzivirira mheni.
Inverter mvura-inoratidza uye anti-corrosion matanho:Iyo inverter inotora yakakwira IP66 nhanho yekudzivirira uye C4&C5 anti-corrosion level kuti ive nechokwadi chekuti inverter inoramba ichishanda pasi pemvura zhinji.
Kubatana kwenhema kwe photovoltaic connector, ingress yemvura mushure mokunge tambo yakuvadzwa, zvichiita kuti pfupi pfupi padivi reD DC kana kudonha kwevhu, zvichiita kuti inverter imire.Naizvozvo, iyo DC arc yekuona basa reiyo inverter yakakoshawo.
2.2 Yese yekudzivirira mheni (kuvaka) zano
Ita basa rakanaka reiyo earthing system, kusanganisira component terminals uye inverters.
Matanho ekudzivirira mheni pane solar panel uye inverter
Kunaya kwezhizha kunogonawo kukonzera sora kukura uye mumvuri zvikamu.Apo mvura inonaya inosuka zvikamu, zviri nyore kukonzera guruva kuunganidza pamicheto yezvikamu, izvo zvichakanganisa basa rinotevera rekuchenesa.
Ita basa rakanaka mukuongorora kwehurongwa, gara uchitarisa kuvharwa uye kusapinda kwemvura mamiriro ephotovoltaic connectors uye tambo, tarisa kana tambo dzakanyoroveswa zvishoma mumvura inonaya, uye kana paine kuchembera uye kuputika kwetambo yekudzivirira sheath.
Photovoltaic simba rekugadzira ndeyese-mamiriro ekunze ekugadzira magetsi.Iyo tembiricha yepamusoro uye mabhanan'ana muzhizha zvakaunza matambudziko akaomarara pakushanda nekuchengetedza photovoltaic magetsi emagetsi.Kubatanidza inverter uye dhizaini yemagetsi emagetsi, Xiaogu inopa mazano ekuvaka, kushanda uye kugadzirisa, uye inotarisira kubatsira kune wese.
