Amazwe amaninzi ehlabathini asebenzisa ukunikezelwa komgangatho we-230 V (i-voltage yesigaba) kunye ne-400V (i-voltage yomgca) kunye neentambo ezingathathi hlangothi kwi-50Hz okanye i-60Hz.Okanye kusenokubakho ipateni yegridi yeDelta yothutho lwamandla kunye nokusetyenziswa kweshishini koomatshini abakhethekileyo.Kwaye njengesiphumo esihambelanayo, ininzi ye-solar inverters yokusetyenziswa kwendlu okanye uphahla lwezorhwebo lwenzelwe kwisiseko esinjalo.
Nangona kunjalo, kukho iimeko ezizodwa, olu xwebhu luya kwazisa ukuba ii-inverters ezibotshwe kwiGridi eziqhelekileyo zisetyenziswa njani kule Gridi ikhethekileyo.
1. Unikezelo lwesigaba sokwahlula
Njenge-United States kunye neKhanada, basebenzisa i-voltage yegridi ye-120 volts ± 6%.Eminye imimandla yaseJapan, eTaiwan, kuMntla Melika, kuMbindi Merika nakumantla oMzantsi Melika kusebenzisa amandla ombane phakathi kwe-100 V kunye ne-127 V kubonelelo lwamandla ombane asekhaya.Ukusetyenziswa kwendlu, ipateni yonikezelo lwegridi, siyibiza ngokuba yi-split-phase phase supply power.
Njengoko i-voltage ye-nominal output yeninzi ye-Renac Power ye-single-phase inverters yelanga yi-230V kunye nocingo olungathathi hlangothi, i-Inverter ayiyi kusebenza ukuba idibaniswe njengesiqhelo.
Ngokudibanisa izigaba ezibini zegridi yamandla (i-voltage yesigaba se-100V, i-110V, i-120V okanye i-170V, njl.) idibanisa kwi-inverter ukuze ilingane ne-220V / 230Vac voltage, i-solar inverter inokusebenza ngokuqhelekileyo.
Isisombululo soqhagamshelwano siboniswe ngolu hlobo lungezantsi:
Phawula:
Esi sisombululo sifanelekile kuphela kwisigaba esisodwa segridi-eboshwe okanye i-hybrid inverters.
2. 230V Igridi yesigaba sesithathu
Kweminye imimandla yaseBrazil, akukho mbane usemgangathweni.Uninzi lweeyunithi ezidibeneyo zisebenzisa i-220 V yombane (isigaba sesithathu), kodwa ezinye - ubukhulu becala kumntla-mpuma - imimandla ikwi-380 V (isigaba somthi).Nangaphakathi kwamanye amazwe ngokwawo, akukho mbane umnye.Ngokokusetyenziswa okwahlukeneyo, inokuba ludibaniso lwe-delta okanye uqhagamshelo lwe-wye.
Ukulungelelanisa inkqubo yombane enjalo, iRenac Power ibonelela ngesisombululo nge-LV version Grid-died 3phase inverters zelanga ze-NAC10-20K-LV, ezibandakanya i-NAC10K-LV, NAC12K-LV, NAC15KLV, NAC15K-LV, enokusebenzisa zombini iNkwenkwezi. Igridi okanye i-Delta Grid ngokugunyazisa kwi-inverter display (kufuneka nje usete ukhuseleko lwe-inverter njenge “Brazil-LV”).
I-Bellowing yi-database ye-MicroLV series inverter.
3. Isiphelo
I-Renac's MicroLV uchungechunge lwesigaba sesithathu sokuguqula i-inverter yenzelwe igalelo lamandla ombane aphantsi, alungiselelwe ngokukodwa usetyenziso oluncinci lwePV yorhwebo.Iphuhliswe njengempendulo esebenzayo kwiimfuno zemarike yaseMzantsi Melika yee-inverters ezine-voltage ephantsi ngaphezulu kwe-10kW, iyasebenza kwiindidi zamandla ombane wegridi ohlukeneyo kummandla, ogubungela ikakhulu i-208V, 220V kunye ne-240V.Nge-MicroLV series inverter, ubumbeko lwenkqubo lunokwenziwa lula ngokunqanda ukufakwa kwe-transformer ebiza kakhulu echaphazela kakubi ukuguqulwa kwenkqubo.
