Inogara nguva yakareba sei ma solar inverters?

Muchikamu chekutanga cheiyi nhevedzano, pv magazini yakaongororahupenyu hunobudirira hwema solar panel, idzo dzakasimba. Muchikamu chino, isu tinoongorora ekugara solar inverters mumhando dzawo dzakasiyana, kuti anogara kwenguva yakareba sei, uye kuti anoshingirira sei.

Iyo inverter, chishandiso chinoshandura magetsi eDC anogadzirwa ne solar panel kuita inoshandisika AC simba, inogona kuuya mune mashoma akasiyana masisitimu.

Iwo maviri makuru marudzi e inverters mukugara maapplication ndeye tambo inverters uye microinverters. Mune mamwe maapplication, tambo inverters ine module-level simba zvemagetsi (MLPE) inonzi DC optimizers. Microinverters uye DC optimizers anowanzo shandiswa pamatenga ane shading mamiriro kana sub-optimal orientation (kwete kumaodzanyemba-yakatarisana).

Mumashandisirwo apo denga rine inosarudzika azimuth (yakatarisana kuzuva) uye zvishoma isina shading nyaya, tambo inverter inogona kuva yakanaka mhinduro.

String inverters kazhinji inouya neyakareruka wiring uye nzvimbo yepakati kuti igadziriswe zviri nyore nevanyanzvi vezuva.Kazhinji ivo vanodhura zvishoma,akadaro Solar Reviews. Inverters inogona kudhura 10-20% yeiyo yakazara solar panel kuisirwa, saka kusarudza iyo chaiyo kwakakosha.

Zvinogara kwenguva yakareba sei?

Nepo solar panels inogona kugara makore makumi maviri nemashanu kusvika makumi matatu kana kupfuura, inverters kazhinji ane hupenyu hupfupi, nekuda kwekukurumidzira kuchembera zvikamu. Chinhu chakajairika chekutadza mu inverters ndeye electro-mechanical kupfeka pane capacitor mune inverter. Iwo ma electrolyte capacitors ane hupenyu hupfupi uye zera nekukurumidza kupfuura zvinhu zvakaoma,akadaro Solar Harmonics.

EnergySage akadarokuti yakajairwa yepakati pekugara tambo inverter ichagara makore angangoita 10-15, uye nekudaro inoda kutsiviwa pane imwe nguva panguva yehupenyu hwemapanera.

String inverterskazhinji vanewaranti yakajairwa kubva ku5-10 makore, mazhinji ane sarudzo yekuwedzera kusvika kumakore makumi maviri. Zvimwe zvibvumirano zvezuva zvinosanganisira kuchengetedza kwemahara uye kutarisa kuburikidza nenguva yechibvumirano, saka zvine hungwaru kuongorora izvi pakusarudza inverters.

Microinverters vane hupenyu hwakareba, EnergySage vakati vanogona kugara makore makumi maviri nemashanu, akareba sekureba sevamwe vavo. Roth Capital Partners yakati maindasitiri ayo anobatika anowanzo taura kutadza kwe microinverter pamwero wakaderera pane tambo inverters, kunyangwe mutengo wepamberi unowanzo kukwira zvishoma mumamicroinverters.

Microinverters kazhinji ane 20 kusvika 25-gore yakajairwa waranti inosanganisirwa. Izvo zvinofanirwa kucherechedzwa kuti nepo microinverters iine waranti yakareba, ichiri tekinoroji nyowani kubva pamakore gumi apfuura kana zvakadaro, uye zvinoramba zvichionekwa kana michina ichizadzisa vimbiso yayo ye20+ yegore.

Izvo zvakafanana zvinoenda kune DC optimizers, ayo anowanzo kupetwa nepakati tambo inverter. Izvi zvikamu zvakagadzirirwa kugara kwe20-25 makore uye zvine waranti yekuenderana nenguva iyoyo.

Kana dziri inverter vanopa, mashoma mabhureki ane makuru emusika share. MuUnited States, Enphase mutungamiri wemusika we microinverters, nepo SolarEdge inotungamira mune tambo inverters. Tesla anga achigadzira mafungu munzvimbo yekugara tambo inverter nzvimbo, achitora chikamu chemusika, kunyangwe zvichiramba zvichionekwa kuti yakawanda sei yekukanganisa kupinda kwemusika kwaTesla, akadaro chinyorwa cheindasitiri kubva kuRoth Capital Partners.

Kukundikana

Ongororo yakaitwa ne kWh Analytics yakawana kuti 80% yekutadza kwesolar array inoitika padanho reinverter. Pane zvikonzero zvakawanda zveizvi.

Maererano ne Fallon Solutions, chimwe chikonzero kukanganisa grid. Yakakwira kana yakaderera voltage nekuda kwekukanganisa kwegrid inogona kuita kuti inverter irege kushanda, uye mabreaker edunhu kana fuse anogona kuvhurwa kuchengetedza inverter kubva kune yakakwira-voltage kutadza.

Dzimwe nguva kukundikana kunogona kuitika pachiyero cheMLPE, uko zvikamu zvemagetsi ekugadzirisa zvinoratidzwa kune tembiricha yepamusoro padenga. Kana kuderedzwa kugadzirwa kuri kuitika, inogona kunge iri mhosva muMLPE.

Kuisa kunofanira kuitwa nemazvo zvakare. Sekutonga kwechigunwe, Fallon yakakurudzira kuti solar panel inokwanisa kusvika 133% ye inverter simba. Kana mapaneru asina kunyatso kufananidzwa nekurudyi-saizi inverter, haazoite nemazvo.

Maintenance

Kuchengeta inverter ichimhanya zvakanyanya kwenguva yakareba, ndizvoyakakurudzirwakuisa mudziyo munzvimbo inotonhorera, yakaoma ine mijenya yemhepo yakachena inotenderera. Vanoisa vanofanirwa kudzivirira nzvimbo dzine zuva rakananga, kunyangwe mabhureki chaiwo emainverters ekunze akagadzirirwa kumira nechiedza chezuva chakawanda kupfuura mamwe. Uye, mukumisikidzwa kwakawanda-inverter, zvakakosha kuve nechokwadi kuti pane kubvumidzwa kwakakodzera pakati pega yega inverter, kuitira kuti pasave nekutamisa kupisa pakati pemainverters.

Iyo yakanakisa tsika yekuongorora kunze kweiyo inverter (kana ichisvikika) kota, kuve nechokwadi kuti hapana zviratidzo zvemuviri zvekukuvadzwa, uye zvese zvinoputika uye zvimbi zvinotonhora hazvina tsvina neguruva.

Zvinokurudzirwawo kuronga ongororo kuburikidza neane rezenisi solar installer makore mashanu ega ega. Kuongorora kunowanzo dhura $200- $ 300, kunyangwe zvimwe zvibvumirano zvezuva zvine mahara kugadzirisa uye kutarisa kwe20-25 makore. Panguva yekuongorora, muongorori anofanira kutarisa mukati me inverter yezviratidzo zvekuora, kukanganisa, kana tupukanana.
