Imirasire y'izuba ihindura amashanyarazi ataziguye (DC) mu guhinduranya amashanyarazi (AC).Inverter nigice cyingenzi cya sisitemu kuko imirasire yizuba yagenewe guhindura urumuri rwizuba ingufu za DC.Biracyaza, urugo rwawe rusaba AC guha ingufu amatara yawe yose nibikoresho byawe.Imirasire y'izuba ihindura amashanyarazi ya DC yakozwe na panneaux solaire mu mashanyarazi ya 240V AC, ishobora noneho gukoreshwa n'umutungo / urugo, ikoherezwa muri gride, cyangwa ikabikwa muri sisitemu yo kubika batiri izuba.
1.Izuba rimurika kumirasire y'izuba itanga amashanyarazi ya Direct (DC).
2.Amashanyarazi ya DC agaburirwa mumashanyarazi yizuba ayihindura amashanyarazi 240V 50Hz AC.
3.Amashanyarazi ya 240V AC akoreshwa mubikoresho byamashanyarazi murugo rwawe.
4.Amashanyarazi asagutse asubizwa muri gride nkuru.
Bateri yo murugo hamwe na sisitemu ya Hybrid nayo iragenda ikundwa cyane, ariko bateri ziracyatera imbere, kandi izuba ryinshi riracyakenera izuba ryabigenewe.
Inyungu nyamukuru ya sisitemu nini cyane ya PV ni uko bizaba byoroshye kongeramo bateri yizuba, gukoresha ubushobozi bwa inverter yizuba kuburyo bwuzuye, kandi bikabyara ingufu nyinshi kumanywa kugirango utazaba ushingiye kuri gride amashanyarazi.Urashobora gutangira gukoresha neza sisitemu ya PV yizuba ushyiraho bateri yizuba, nka Tesla Powerwall 2.
Ibicuruzwa byinshi biva mu zuba nabyo bifite monitor ya Wi-Fi, iguha amakuru nyayo kubyerekeye ingufu z'izuba zitangwa.Nibyiza cyane mugihe ufite imirasire yizuba ikomeye ishobora gupima ingufu zikoreshwa mugutanga amashanyarazi.
Inverter ikoreshwa iki?
Buri mashanyarazi akomoka ku mirasire y'izuba agomba kugira imirasire y'izuba.Bakora imirimo ibiri y'ingenzi:
Guhindura kuva DC kuri AC
Imirasire y'izuba yose itanga Direct Direct (DC), igomba guhinduka muburyo bwo guhinduranya (AC), ubwoko bw'amashanyarazi urugo rwawe rushobora gukoresha na inverter izuba.
Ikurikiranwa ry'ingufu ntarengwa (MPPT)
Ingano yumucyo wizuba hamwe nubushyuhe bwizuba bigira ingaruka kuburyo imirasire yizuba ikora neza umunsi wose.Bishatse kuvuga ko voltage numuyoboro wizuba ushobora kubyara nabyo bishobora guhinduka buri gihe.Imirasire y'izuba ihitamo neza kuvanga byombi bizatanga amashanyarazi ntarengwa ukoresheje inzira izwi nka Maximum Power Point (MPP) ikurikirana.

Imirasire y'izuba
Ikurikiranyanyuguti
Ubwoko bwa sunver inverter ikoreshwa cyane muri sisitemu yo guturamo izuba ni umugozi uhinduranya kuko buri kwishyiriraho bisanzwe bisaba imwe.Imirasire y'izuba myinshi ihuza inverter imwe.Noneho, kumikoreshereze yimbere murugo, ihindura DC muri AC.
Micro Inverters
Buri mirasire y'izuba ikenera inverter ntoya yitwa microinverter kugirango yongere imbaraga zayo kurwego rwa module.Ndetse hamwe nigicucu cyigice, buri mirasire yizuba iracyatanga amashanyarazi menshi.Buri paneli ya voltage isohoka itezimbere ukoresheje microinverter kugirango yongere umusaruro mwinshi.Kubera ko buri micro-inverter ihujwe nindi, sisitemu ikomeza guhindura DC kuri AC nubwo microinverter imwe yananiwe.
Inverteri yo hagati
Nubwo ari binini kandi birashobora gukomeza umurongo urenze umwe aho kuba umwe gusa, birasa cyane nu mugozi uhindura.
Bitandukanye nu mugozi uhinduranya, imirongo yimbere ihujwe na bix, hamwe nimbaraga za DC zerekeza mumasanduku yo hagati, aho ihindurwamo amashanyarazi ya AC.Ibi ahanini bikorera ubucuruzi kuruta intego zimbere mu gihugu.Ibi biranga ibikoresho byubucuruzi ninganda zikoresha izuba.
Batteri ishingiye kuri inverter
Banki ya batiri irakenewe kugirango inverteri ikora.Ihindura amashanyarazi ya banki ya DC ingufu za AC.Bashobora gutanga ingufu no mugihe cyo kubura amashanyarazi nka inverteri ya Hybrid.Inverteri ya bateri ifite imbogamizi zo kubangamira terefone, radio, no kwakira televiziyo kubera urusaku rwinshi.Gushiraho sine waves bizagufasha kugabanya intervention.
Imbaraga nziza
Imbaraga zitanga imbaraga zirashobora gushyirwaho muri sisitemu ifite imirongo ya paneli hamwe numugozi uhinduranya nubwo atari inverter.Kimwe na microinverters, baremeza ko ibisohoka mumirasire yizuba isigaye murugozi bitazagira ingaruka mugihe kimwe muricyo gicucu, cyanduye, cyangwa cyananiranye mubundi buryo.
Sisitemu ya Solar PV hamwe na inverter zisabwa
Imiyoboro ihujwe na gride igenewe imirasire y'izuba ihuza imirasire y'izuba, ubwoko bwa sisitemu isanzwe.Iyo bibaye ngombwa, batumiza amashanyarazi yingirakamaro muri gride kandi bagakomeza imikoranire yuburyo bubiri nayo, yohereza ingufu zizuba kuri yo.
Imashini ya Hybrid ikora hamwe na sisitemu yizuba ya Hybrid, izwi kandi nka inverteri-moderi nyinshi, in-bateri yiteguye cyangwa sisitemu yo kubika izuba.Barashobora kwaka no kuvana amashanyarazi muburyo bwa bateri kandi bafite imikorere imwe na grid-tie inverter.
Imashini zitanga amashanyarazi zikoreshwa muri sisitemu zituruka ku mirasire y'izuba, izwi kandi nka sisitemu y’amashanyarazi yigenga rwose, kugira ngo itange ingufu mu gihe cyo guhagarika amashanyarazi.
Inverter ya off-grid ntishobora guhuzwa na gride kandi igomba kuba ifite backup ya bateri kugirango ikore.
