Chifukwa cha kusiyanasiyana kwa nyumbazi, mosakayikira zidzabweretsa kusiyanasiyana kwa ma solar panel. Pofuna kupititsa patsogolo kusinthika kwa mphamvu ya dzuwa poganizira maonekedwe okongola a nyumbayi, izi zimafuna kuti ma inverters athu azitha kupeza njira yabwino kwambiri ya mphamvu ya dzuwa. Kutembenuka. Njira zodziwika kwambiri za solar inverter padziko lapansi ndi izi: ma inverters apakati, ma inverters a zingwe, ma inverters a zingwe zambiri ndi ma inverters agawo. Tsopano ife kusanthula ntchito angapo inverters.
Ma inverters apakati amagwiritsidwa ntchito m'makina omwe ali ndi malo akuluakulu opangira magetsi a photovoltaic (》10kW). Zingwe zambiri zofananira za photovoltaic zimalumikizidwa ndi kulowetsa kwa DC kwa inverter yapakati yomweyi. Nthawi zambiri, magawo atatu amphamvu a IGBT amagwiritsidwa ntchito pamphamvu kwambiri. Mphamvu yotsika imagwiritsa ntchito ma transistors ochita kumunda ndi chowongolera chosinthira cha DSP kuti apititse patsogolo mphamvu yamagetsi opangidwa, ndikupangitsa kuti ikhale pafupi kwambiri ndi sine wave pano. Chinthu chachikulu ndi mphamvu yapamwamba komanso mtengo wotsika wa dongosolo. Komabe, zimakhudzidwa ndi kufanana kwa zingwe za photovoltaic ndi shading pang'ono, zomwe zimapangitsa kuti pakhale mphamvu komanso mphamvu ya dongosolo lonse la photovoltaic. Panthawi imodzimodziyo, kudalirika kwa mphamvu zamagetsi kwa dongosolo lonse la photovoltaic kumakhudzidwa ndi kusagwira bwino ntchito kwa gulu la photovoltaic unit. Njira yaposachedwa yofufuza ndikugwiritsa ntchito kuwongolera kwa ma vector mlengalenga komanso kupanga zolumikizira zatsopano za inverter topology kuti zipezeke bwino kwambiri pakalemedwe pang'ono.
Pa SolarMax centralized inverter, mutha kulumikiza bokosi la mawonekedwe a photovoltaic kuti muwunikire chingwe chilichonse cha photovoltaic windsurfing. Ngati chimodzi mwa zingwe sichikugwira ntchito bwino, dongosololi lidzapereka chidziwitsochi kwa wolamulira wakutali Panthawi imodzimodziyo, chingwechi chikhoza kuimitsidwa ndi kulamulira kwakutali, kotero kuti kulephera kwa chingwe cha photovoltaic zingwe sikungachepetse ndikukhudza ntchito ndi kutulutsa mphamvu kwa dongosolo lonse la photovoltaic.
Ma inverters a zingwe akhala ma inverters otchuka kwambiri pamsika wapadziko lonse lapansi. Inverter ya chingwe imatengera lingaliro la modular. Chingwe chilichonse cha photovoltaic (1kW-5kW) chimadutsa pa inverter, chimakhala ndi mphamvu yayikulu yotsatirira kumapeto kwa DC, ndipo chimalumikizidwa mofanana kumapeto kwa AC. Zomera zambiri zamphamvu za photovoltaic zimagwiritsa ntchito ma inverters a zingwe. Ubwino wake ndikuti sichimakhudzidwa ndi kusiyana kwa ma module ndi mithunzi pakati pa zingwe, ndipo nthawi yomweyo imachepetsa ntchito yabwino kwambiri ya ma module a photovoltaic.
Kusagwirizana ndi inverter, potero kumawonjezera kuchuluka kwa magetsi. Zopindulitsa zamakonozi sizimangochepetsa mtengo wa dongosolo, komanso zimawonjezera kudalirika kwa dongosolo. Panthawi imodzimodziyo, lingaliro la "mbuye-kapolo" limayambitsidwa pakati pa zingwe, kotero kuti pamene chingwe chimodzi cha mphamvu yamagetsi sichikhoza kupanga inverter imodzi yokha mu dongosolo, ma seti angapo a zingwe za photovoltaic amagwirizanitsidwa palimodzi, ndipo imodzi kapena imodzi. angapo a iwo akhoza kugwira ntchito. , Kuti apange magetsi ambiri. Lingaliro laposachedwa ndilakuti ma inverters angapo amapanga "timu" kuti alowe m'malo mwa lingaliro la "bwana-kapolo", zomwe zimapangitsa kudalirika kwa dongosololi kupita patsogolo. Pakali pano, ma inverters opanda zingwe a transformerless atsogola.
Mipikisano zingwe inverter amatenga ubwino wa centralized inverter ndi chingwe inverter, amapewa zofooka zake, ndipo angagwiritsidwe ntchito malo photovoltaic mphamvu ya kilowatts angapo. Mu inverter ya zingwe zambiri, kutsata kwamphamvu kosiyanasiyana kwamphamvu ndi zosinthira za DC-to-DC zimaphatikizidwa. Ma DC awa amasinthidwa kukhala mphamvu ya AC ndi inverter wamba ya DC-to-AC ndikulumikizidwa ku gridi. Zosiyanasiyana zovotera zingwe za photovoltaic (monga: mphamvu zovoteledwa, kuchuluka kwa magawo osiyanasiyana mu chingwe chilichonse, opanga zinthu zosiyanasiyana, ndi zina), ma module a photovoltaic amitundu yosiyanasiyana kapena ukadaulo wosiyanasiyana, ndi zingwe zanjira zosiyanasiyana (monga : Kum'mawa, Kumwera ndi Kumadzulo), ma angles osiyana kapena mithunzi, akhoza kulumikizidwa ndi inverter wamba, ndipo chingwe chilichonse chikugwira ntchito pamlingo wawo waukulu kwambiri.
Panthawi imodzimodziyo, kutalika kwa chingwe cha DC kumachepetsedwa, zotsatira za mthunzi pakati pa zingwe ndi kutayika chifukwa cha kusiyana pakati pa zingwe zimachepetsedwa.
The chigawo inverter ndi kulumikiza aliyense photovoltaic chigawo chimodzi ndi inverter, ndipo chigawo chilichonse ali osiyana pazipita mphamvu pachimake kutsatira, kotero kuti chigawo ndi inverter bwino chikufanana. Nthawi zambiri amagwiritsidwa ntchito mu 50W mpaka 400W zopangira magetsi a photovoltaic, mphamvu yonseyi ndiyotsika kuposa ma inverters a zingwe. Popeza imalumikizidwa mofanana pa AC, izi zimawonjezera zovuta za waya kumbali ya AC ndipo zimakhala zovuta kusunga. Nkhani ina yomwe iyenera kuthetsedwa ndi momwe mungalumikizire gridi mogwira mtima. Njira yosavuta ndikulumikiza mwachindunji ku gridi kudzera pa socket wamba ya AC, yomwe ingachepetse mtengo ndi kuyika zida, koma nthawi zambiri miyezo yachitetezo cha gridi sangalole. Pochita izi, kampani yamagetsi ikhoza kutsutsa kuti chipangizo chopangira magetsi chikulumikizidwa mwachindunji ndi sockets wamba wamba ogwiritsa ntchito apanyumba. Chinanso chokhudzana ndi chitetezo ndi chakuti chosinthira chodzipatula (ma frequency apamwamba kapena otsika) chimafunika, kapena chosinthira chosasinthika chimaloledwa. Iziinverteramagwiritsidwa ntchito kwambiri mu makoma a makatani a galasi.
