Kodi ma inverter okhala ndi dzuwa amakhala nthawi yayitali bwanji?

Mu gawo loyamba la mndandandawu, magazini ya pv idawunikiranso zamoyo wopindulitsa wa solar panels, zomwe zimakhala zolimba. Mu gawo ili, tikuwunika ma inverter a dzuwa okhala m'mitundu yosiyanasiyana, kutalika kwake, komanso momwe amalimba.

Inverter, chipangizo chomwe chimasintha mphamvu ya DC yopangidwa ndi mapanelo adzuwa kukhala mphamvu yogwiritsira ntchito AC, imatha kubwera mosiyanasiyana.

Mitundu iwiri ikuluikulu ya ma inverters m'malo okhalamo ndi ma inverters a zingwe ndi ma microinverters. Muzinthu zina, ma inverters a zingwe amakhala ndi ma module-level power electronics (MLPE) otchedwa DC optimizers. Ma Microinverters ndi DC optimizers nthawi zambiri amagwiritsidwa ntchito padenga lomwe lili ndi mithunzi kapena mawonekedwe abwino kwambiri (osati kumwera).

M'mapulogalamu omwe denga limakhala ndi azimuth yabwino (lolowera kudzuwa) komanso zovuta zochepa za shading, inverter ya chingwe ikhoza kukhala yankho labwino.

Ma string inverters nthawi zambiri amabwera ndi mawaya osavuta komanso malo apakati kuti akonzedwe mosavuta ndi akatswiri oyendera dzuwa.Nthawi zambiri zimakhala zotsika mtengo,adatero Solar Reviews. Ma inverters amatha kuwononga 10-20% ya kuchuluka kwa ma solar panels, kotero kusankha yoyenera ndikofunikira.

Zimatenga nthawi yayitali bwanji?

Ngakhale ma solar atha kukhala zaka 25 mpaka 30 kapena kupitilira apo, ma inverter nthawi zambiri amakhala ndi moyo waufupi, chifukwa chakukalamba mwachangu. Gwero lodziwika bwino la kulephera kwa ma inverters ndi kuvala kwa ma electro-mechanical pa capacitor mu inverter. Ma electrolyte capacitor amakhala ndi moyo wamfupi komanso zaka mwachangu kuposa zida zowuma,adatero Solar Harmonics.

EnergySage adaterokuti chosinthira chachingwe chokhazikika chapakati chimakhala pafupifupi zaka 10-15, motero chidzafunika kusinthidwa nthawi ina pa moyo wa mapanelo.

Ma inverters a zingwezambirizitsimikizo wamba kuyambira zaka 5-10, ambiri ndi mwayi kuwonjezera kwa zaka 20. Mapangano ena a dzuwa amaphatikizapo kukonza ndi kuyang'anira kwaulere kudzera mu nthawi ya mgwirizano, kotero ndi nzeru kuyesa izi posankha ma inverters.

Ma Microinverters amakhala ndi moyo wautali, EnergySage adati nthawi zambiri amatha zaka 25, pafupifupi malinga ndi anzawo. Roth Capital Partners idati omwe amalumikizana nawo pamakampani nthawi zambiri amafotokoza kulephera kwa ma microinverter pamtengo wotsika kwambiri kuposa ma inverters azingwe, ngakhale mtengo wakutsogolo nthawi zambiri umakhala wokwera pang'ono.

Ma Microinverters amakhala ndi chitsimikizo chazaka 20 mpaka 25 chophatikizidwa. Tiyenera kukumbukira kuti ngakhale ma microinverters ali ndi chitsimikizo chautali, akadali teknoloji yatsopano kuyambira zaka khumi zapitazi, ndipo zikuwonekerabe ngati zipangizozo zidzakwaniritsa lonjezo la zaka 20 +.

Zomwezo zimapitanso kwa DC optimizers, yomwe nthawi zambiri imaphatikizidwa ndi inverter yazingwe yapakati. Zidazi zidapangidwa kuti zikhale zaka 20-25 ndipo zimakhala ndi chitsimikizo kuti zigwirizane ndi nthawiyo.

Ponena za opereka ma inverter, mitundu ingapo imakhala ndi gawo lalikulu pamsika. Ku United States, Enphase mtsogoleri wamsika wama microinverters, pomwe SolarEdge imatsogolera ma inverters a zingwe. Tesla yakhala ikupanga mafunde m'malo osinthira zingwe zogona, kutenga gawo la msika, ngakhale zikuwonekabe kuti kulowa kwa Tesla kudzakhudza bwanji msika, idatero kalata yochokera ku Roth Capital Partners.

Zolephera

Kafukufuku wopangidwa ndi kWh Analytics adapeza kuti 80% ya zolephera za solar array zimachitika pamlingo wa inverter. Pali zifukwa zambiri za izi.

Malinga ndi Fallon Solutions, chifukwa chimodzi ndi zolakwika za gridi. Ma voliyumu apamwamba kapena otsika chifukwa cha vuto la gridi amatha kupangitsa kuti inverter asiye kugwira ntchito, ndipo zowononga madera kapena ma fuse amatha kutsegulidwa kuti ateteze inverter ku kulephera kwamphamvu kwambiri.

Nthawi zina kulephera kumatha kuchitika pamlingo wa MLPE, pomwe zida zopangira mphamvu zimawonekera kutentha kwambiri padenga. Ngati kupanga kuchepetsedwa kukuchitika, zitha kukhala vuto mu MLPE.

Kuyikanso kuyenera kuchitidwa moyenera. Monga lamulo la chala chachikulu, Fallon adalimbikitsa kuti mphamvu ya solar iyenera kukhala mpaka 133% ya mphamvu ya inverter. Ngati mapanelo sakufananizidwa bwino ndi inverter yowoneka bwino, sangachite bwino.

Kusamalira

Kuti inverter ikhale yogwira ntchito kwa nthawi yayitali, ndizoanalimbikitsakukhazikitsa chipangizo pamalo ozizira, owuma ndi mpweya wabwino wochuluka. Oyika akuyenera kupewa madera omwe ali ndi kuwala kwa dzuwa, ngakhale ma inverter akunja amapangidwa kuti azitha kupirira kuwala kwa dzuwa kuposa ena. Ndipo, pakuyika ma inverter ambiri, ndikofunikira kuwonetsetsa kuti pali chilolezo choyenera pakati pa inverter iliyonse, kuti pasakhale kutentha pakati pa ma inverters.

Ndibwino kuti muyang'ane kunja kwa inverter (ngati ikupezeka) kotala, kuonetsetsa kuti palibe zizindikiro zowonongeka, ndipo mapiko onse ndi zipsepse zozizira zimakhala zopanda dothi ndi fumbi.

Ndikulimbikitsidwanso kukonza zoyendera kudzera pa choyikira cholozera cha solar zaka zisanu zilizonse. Kuyendera nthawi zambiri kumawononga $ 200- $ 300, ngakhale ma contract ena adzuwa amakhala ndi kukonza ndi kuyang'anira kwaulere kwa zaka 20-25. Poyang'ana, woyang'anira ayenera kuyang'ana mkati mwa inverter kuti aone zizindikiro za dzimbiri, zowonongeka, kapena tizirombo.
