Sisitemu ihuriweho na DC ntabwo ikwiriye guhinduranya sisitemu ihari ya gride. Uburyo bwa DC bwo guhuza cyane cyane bufite ibibazo bikurikira: Icya mbere, sisitemu ikoresha guhuza DC ifite ibibazo bijyanye no gukoresha insinga zigoye hamwe no gushushanya module idasanzwe mugihe uhindura sisitemu ihari ya gride; icya kabiri, gutinda guhinduranya hagati ya grid-ihujwe na off-grid ni ndende, bikaba bigoye kubakoresha. Uburambe bw'amashanyarazi burakennye; icya gatatu, imikorere yubwenge yubwenge ntabwo yuzuye bihagije kandi igisubizo cyo kugenzura ntabwo gihagije mugihe, kuburyo bigoye gushyira mubikorwa microgrid ikoreshwa mumashanyarazi yose. Kubwibyo, ibigo bimwe byahisemo inzira ya tekinoroji ya AC ihuza, nka Yuneng.
Sisitemu yo guhuza AC ituma ibicuruzwa byoroha. Yuneng amenya inzira zibiri zingufu zihuza uruhande rwa AC hamwe na sisitemu ya Photovoltaque, bivanaho gukenera kwinjira muri bisi ya fotokopi DC, bigatuma ibicuruzwa byoroha; itahura off-grid ihuza binyuze muri software igenzurwa nigihe nyacyo hamwe nibikoresho byogutezimbere ibikoresho bya Millisecond; Binyuze mu kugenzura ibicuruzwa biva mu bubiko hamwe no guhanga udushya twa sisitemu yo gutanga amashanyarazi no gukwirakwiza amashanyarazi, microgrid ikoreshwa mu gutanga amashanyarazi yose yo mu rugo iyobowe nagasanduku kayobora byikora.
Impinduka nini yo guhindura ibicuruzwa byahujwe na AC iri munsi gato ugereranije niyivangavanga. Jinlong na GoodWe nabo bohereje ibicuruzwa bihujwe na AC, cyane cyane byibanda ku isoko ryo guhindura imigabane. Ihinduka ryinshi ryibicuruzwa byahujwe na AC ni 94-97%, biri munsi gato ugereranije n’ibivangwa na Hybrid. Ibi biterwa ahanini nuko ibice bigomba guhinduka bibiri mbere yuko bibikwa muri bateri nyuma yo kubyara amashanyarazi, bigabanya imikorere yo guhindura.
Kugereranya ibicuruzwa bihujwe na AC biva mu nganda zo murugo
