I-Inverter ehlanganisiwe ye-AC
Amasistimu ahlanganisiwe we-DC awalungele ukuphinda abuyele ezinhlelweni ezikhona ezixhunywe ngegridi. Indlela yokuhlangana ye-DC ikakhulukazi inezinkinga ezilandelayo: Okokuqala, uhlelo olusebenzisa i-DC coupling lunezinkinga nge-wiring eyinkimbinkimbi ye-wiring kanye ne-design evuselelayo ye-module Okwesibili, ukubambezeleka ekushintsheni phakathi kwegridi exhunywe ne-grid kudala, okunzima ukuthi abasebenzisi basebenzise. Isipiliyoni sikagesi simpofu; Okwesithathu, imisebenzi yokulawula ehlakaniphile ayigcwele ngokwanele futhi impendulo yokulawula ayikho ngesikhathi ngokwanele, okwenza kube nzima ukufeza izinhlelo zokusebenza ze-microgid ukuze kufakwe i-microgid. Ngakho-ke, ezinye izinkampani zikhethe umzila wezobuchwepheshe we-AC Coupling, njengeYuneng.
Uhlelo lokuhlanganisa i-AC lwenza ukufakwa komkhiqizo kube lula. I-Yuneng ibona ukugeleza kwamandla amabili ngokuhlanganisa uhlangothi lwe-AC kanye nohlelo lwe-Photovoltaic, kuqeda isidingo sokufinyelela kwi-Photovoltaic DC ibhasi, okwenza ukufakwa komkhiqizo kube lula; Ibona ukuhlanganiswa kwe-off-grid ngokuhlanganiswa kokulawulwa kwesikhathi sangempela se-software kanye ne-Hardware Design Encuments Ukushintsha kwe-millisecond-level switch; Ngokuphawula kokukhishwa kwe-inverter ye-Energy Storage kanye nokwakhiwa okusha okuhlanganisiwe kohlelo lokuhlinzekwa kwamandla kanye nohlelo lokusabalalisa, uhlelo lokusebenza lwe-microgid lwamandla endlu wonke asendlini ngaphansi kokulawulwa kwebhokisi lokulawula okuzenzakalelayo.
Ukusebenza okuhle kakhulu kokuguqulwa kwemikhiqizo ehlanganisiwe kuphansi kancane kunalokho kwe-hybrid amandla. UJinlong no-goodwe baphinde bathumela imikhiqizo ehlanganisiwe ye-AC, ikakhulukazi ebhekise emakethe yenguquko yesitoko. Ukusebenza okuhle kakhulu kwemikhiqizo ehlanganisiwe ye-AC kungu-94-97%, okuphansi kancane kunalokho kwe-hybrid alverters. Lokhu kungenxa yokuthi izakhi kufanele ziguqulwe kabili ngaphambi kokuthi zigcinwe ebhethri ngemuva kokukhiqiza ugesi, okunciphisa ukusebenza kahle.
