Kune solar grid-yakabatana system, nguva uye mamiriro ekunze zvinokonzeresa shanduko mumwaranzi yezuva, uye voltage pamagetsi inogara ichichinja. Kuti uwedzere huwandu hwemagetsi anogadzirwa, inovimbiswa kuti magetsi ezuva anogona kuendeswa nepamusoro-soro kana zuva risina simba uye rakasimba. Simba, kazhinji boost boost system inowedzerwa kune inverter kuti iwedzere voltage panzvimbo yayo yekushandisa.
Iyi diki inotevera inotsanangura chikonzero nei uchifanira kushandisa boost boost, uye sei boost boost system inogona kubatsira solar simba system kuwedzera simba rekugadzira.
Sei Kuwedzera Boost Circuit?
Chekutanga pane zvese, ngatitarisei kune yakajairika inverter system mumusika. Iyo ine inosimudzira inosimudzira wedunhu uye inverter wedunhu. Iyo yepakati yakabatana kuburikidza neDC bhazi.
Iyo inverter yedunhu inoda kushanda nemazvo. Bhazi reDC rinofanirwa kuve rakakwirira kupfuura grid voltage peak (matatu-phase system yakakwira kupfuura kukosha kweiyo voltage line), kuitira kuti simba rigone kubuda kune grid kumberi. Kazhinji kuitira kushanda zvakanaka, bhazi reDC rinowanzochinja negridi voltage. , kuve nechokwadi kuti yakakwirira kudarika grid remagetsi.
Kana iyo panel voltage yakakwira kupfuura inodiwa voltage yebhasibar, iyo inverter ichashanda zvakananga, uye iyo MPPT voltage icharamba ichitevera kusvika pakakwirira. Nekudaro, mushure mekusvika kune yakaderera bhazi voltage inodiwa, haigone kudzikiswa zvakare, uye yakanyanya kunaka poindi haigone kuwanikwa. Huwandu hweMPPT hwakaderera kwazvo, izvo zvinoderedza zvakanyanya simba rekugadzira magetsi uye purofiti yemushandisi haigone kuvimbiswa. Saka panofanira kunge paine nzira yekugadzirisa kukanganisa uku, uye mainjiniya anoshandisa Boost boost maseketi kuita izvi.
Ko Boost Inowedzera sei chiyero cheMPPT kuwedzera simba rekugadzira?
Kana iyo voltage yepaneti yakakwira kupfuura iyo voltage inodiwa nebhasi, iyo boost booster circuit iri munzvimbo yekuzorora, simba rinounzwa kune inverter kuburikidza ne diode yayo, uye inverter inopedzisa iyo MPPT yekutevera. Mushure mekusvika kune inodiwa voltage yebhasibar, iyo inverter haigone kutora. MPPT yakashanda. Panguva ino, chikamu chekusimudzira chakatora kutonga kweMPPT, yakateedzera MPPT, uye yakasimudza bhazi kuti ive nechokwadi chekuti magetsi ayo.
Nehupamhi hwakawanda hweMPPT yekutevera, iyo inverter system inogona kuita basa rakakosha mukuwedzera voltage ye solar panels panguva yemangwanani, hafu yeusiku, uye mazuva ekunaya. Sezvatinogona kuona mumufananidzo uri pasi apa, simba renguva-chaiyo riri pachena. Kurudzirai.
Sei simba guru inverter richiwanzoshandisa akawanda Boost boost circuits kuwedzera nhamba yeMPPT maseketi?
Semuenzaniso, 6kw system, zvichienderana ne3kw kusvika pamatenga maviri, maviri MPPT inverters anofanirwa kusarudzwa panguva ino, nekuti pane maviri akazvimirira epamusoro ekushanda nzvimbo, zuva remangwanani rinobuda kubva kumabvazuva, rakananga kuratidzwa kune A pamusoro Pasolar panel. , iyo voltage uye simba paA side yakakwirira, uye B side yakaderera zvikuru, uye masikati inopesana. Kana paine musiyano pakati pemagetsi maviri, iyo yakaderera voltage inofanirwa kukwidziridzwa kuitira kuendesa simba kubhazi uye kuona kuti inoshanda pane yakanyanya simba poindi.
Chikonzero chimwe chete, nzvimbo ine makomo munzvimbo yakaoma kwazvo, zuva rinoda kuvhenekerwa kwakawanda, saka rinoda yakazvimirira MPPT, saka iyo yepakati uye yakakwirira simba, senge 50Kw-80kw inverters inowanzo 3-4 yakazvimirira Boost, inowanzotaurwa. 3-4 yakazvimirira MPPT.
