Inverter ni ubwonko n'umutima wa sisitemu yo gukora ingufu za photovoltaic. Mu gihe cyo gukora ingufu za photovoltaic zikomoka ku mirasire y'izuba, ingufu zikomoka ku gice cya photovoltaic ni ingufu za DC. Ariko, imizigo myinshi ikenera ingufu za AC, kandi sisitemu yo gutanga ingufu za DC ifite imbogamizi zikomeye kandi ntiyoroheye guhindura voltage. , urwego rw'imizigo narwo ni ruto, uretse imizigo yihariye y'ingufu, inverters zirasabwa guhindura ingufu za DC muri AC. Inverter ya photovoltaic ni umutima wa sisitemu yo gukora ingufu za photovoltaic zikomoka ku mirasire y'izuba, ihindura umuriro utaziguye ukorwa na module za photovoltaic mo umuriro usimburana, hanyuma ikawohereza ku mutwaro cyangwa grid yo mu gace, kandi ni igikoresho cy'amashanyarazi gifite imirimo ijyanye no kurinda.
Inverter y'izuba igizwe ahanini n'ibikoresho by'amashanyarazi, imbaho zo kugenzura, abahuza imiyoboro y'amashanyarazi, abayungurura imiyoboro, abahuza imashini, abahindura amashanyarazi, abahuza imiyoboro y'amashanyarazi, abahuza imiyoboro y'amashanyarazi n'utubati. Igikorwa cyo kuyikora kirimo gutunganya ibice by'ikoranabuhanga mbere y'uko bitegurwa, guteranya imashini neza, gupima no gupakira imashini neza. Iterambere ryayo rishingiye ku iterambere ry'ikoranabuhanga ry'amashanyarazi, ikoranabuhanga ry'ibikoresho bya semiconductor n'ikoranabuhanga rigezweho ryo kugenzura.
Ku byuma bihindura imirasire y'izuba, kunoza imikorere myiza y'amashanyarazi ni ingingo ihoraho, ariko iyo imikorere myiza ya sisitemu irushaho kwiyongera, hafi hafi ya 100%, kunoza imikorere myiza bizaherekezwa n'imikorere ihendutse. Kubwibyo, uburyo bwo kubungabunga imikorere myiza, ariko no kubungabunga igiciro cyiza bizaba ingingo y'ingenzi muri iki gihe.
Ugereranyije n'ibikorwa byo kunoza imikorere myiza ya inverter, uburyo bwo kunoza imikorere myiza ya sisitemu yose ya inverter buri kugenda buba ikindi kibazo cy'ingenzi kuri sisitemu z'ingufu zikomoka ku mirasire y'izuba. Mu mirasire y'izuba, iyo hagaragaye agace k'igicucu ka 2%-3%, kuri inverter ikoresha imikorere ya MPPT, imbaraga zikomoka kuri sisitemu muri iki gihe zishobora kugabanukaho hafi 20% iyo ingufu zisohoka ari nke. Kugira ngo urusheho kumenyera ibintu nk'ibi, ni uburyo bwiza cyane bwo gukoresha uburyo bwo kugenzura bwa MPPT kuri buri wese cyangwa bwinshi bwa MPPT kuri modules z'izuba imwe cyangwa igice.
Kubera ko sisitemu ya inverter iri mu mikorere ihujwe n'umuyoboro w'amashanyarazi, gusohoka kw'iyi sisitemu ku butaka bizatera ibibazo bikomeye by'umutekano; byongeye kandi, kugira ngo inoze imikorere myiza ya sisitemu, imirasire y'izuba myinshi izahuzwa mu buryo bukurikiranye kugira ngo ikore voltage nyinshi ya DC output; Bitewe n'uko habaho imiterere idasanzwe hagati ya electrodes, biroroshye gukora DC arc. Bitewe n'voltage nyinshi ya DC, biragoye cyane kuzimya arc, kandi biroroshye cyane guteza inkongi. Bitewe no gukoresha sisitemu za inverter z'izuba mu buryo bukwirakwira, ikibazo cy'umutekano wa sisitemu nacyo kizaba igice cy'ingenzi cy'ikoranabuhanga rya inverter.
