Sezvo chinangwa che "dual carbon" chakagadzwa, yakagovaniswa photovoltaic yakafarirwa nekuda kwemabhenefiti ayo ekudzikisa kabhoni emission kuderedzwa, akasiyana mashandisirwo ekushandisa uye nyore kudzoka pakudyara.Nekudaro, nekukurumidza kuwedzera kweiyo yakaiswa simba, kune zvakare akawanda ekurwadziwa mapoinzi pamusika, senge DC yakakwira voltage, barrel effect, kushanda uye kugadzirisa matambudziko...... Izvi zvinotungamira kune kuchengetedzwa kunetseka uye kushaikwa kwezvinodiwa. kudzoka pakudyara kwevashandisi vekupedzisira.
Kune mapoinzi ekurwadziwa ari pamusoro, Wo Mai micro inverter inogona kugadziriswa nyore.Ikozvino, isu tinosanganisa yazvino musika dambudziko, yakadzama ongororo yeWo Mai micro inverse mhinduro, kuti uzive.

Kurwadziwa kwemusika poindi # 1: Chengetedzo
Mumakore achangopfuura, imba photovoltaic moto inowanzoitika, 80% iyo inokonzerwa neDC arc inokonzerwa netsika inverter DC high voltage.Uyezve, ma photovoltaic systems akadaro anowanzoiswa pamatenga edzimba kana mafekitari.Kana moto kana kuputika kwaitika, zvinounza kurasikirwa kwepfuma kusingayereki uye kunyange kuisa hupenyu munjodzi.
Uye zvakare, kuchine mazana kana kunyange zviuru zve volts eDC mune inopisa system.Kana vanodzima moto vakamhanyira kunonunura, zvinogona kuva nemigumisiro yakaipa.Nekuda kweizvozvo, vekutanga vanopindura kazhinji vanofanirwa kumirira kuti chirimwa chigopisa zvachose vasati vatanga basa ravo, izvo zvinowanzo tungamira kunonoka kukuru mukuedza kwekudzima moto.

Yakaderera voltage kuchengetedza, hapana njodzi yemoto uye njodzi yemagetsi kuvhunduka
Hemai micro inverter yakabatana kune photovoltaic system yakafanana, ichiita kuti rutivi rweDC rwehurongwa hugadzikane paanenge 40V low voltage, kubva pamudzi kubvisa njodzi dzemoto uye njodzi yemagetsi.Hatifanirwe kunetseka nezve DC arc moto pane micro-retrograde power plant.
Kunyangwe iyo micro inverter system ine emergency nekuda kwekunze kwezvinhu, mushure mekuvhara sisitimu, vanopindura vekutanga havazotarisana nenjodzi yekuvhunduka kwemagetsi nekuti hapana DC yakakwira voltage muPV chirimwa.

Kurwadziwa kwemusika poindi 2: the barrel effect
Imwe neimwe photovoltaic pani ine akasiyana ekubuda maitiro, seazvino, voltage uye yakakwana yekushandisa poindi.Izvi zvisinganzwisisiki zvichava pachena sezvo photovoltaic systems inoshandiswa kunze kwenguva yakareba uye makore zvakasikwa.Maitiro ekugadzira magetsi echinyakare photovoltaic system anowirirana zvakanyanya ne "huni barrel effect": iyo yechinyakare photovoltaic system inogadzirwa munhevedzano, uye iyo yakazara simba rekugadzira yeakateedzana photovoltaic mapaneru anoenderana zvakanyanya nekubuda maitiro eiyo isina kusimba photovoltaic. mapaneru munhevedzano, zvinoreva kuti "vasina simba" vachakwevera timu pasi uye kukanganisa mari yekugadzira magetsi.

Component-level MPPT tekinoroji inobvisa iyo barrel maitiro
Tichifunga nezve "cask effect", Wo Mai micro reverse mushonga.Yayo chikamu-chikamu cheMPPT controller inoteedzera iyo yakanyanya simba poindi yePV module yega yega.Kunyangwe kana imwe PV module isiri kushanda nemazvo, haizokanganisa mamwe maPV module.Semuenzaniso, mune iyo yose photovoltaic system, kana chikamu chakakuvadzwa kana kuvharwa, iyo yakanyanya simba yekuteedzera controller yezvimwe zvikamu icharamba ichichengetedza hukuru hwavo hwekuita.
