Amazwe amaningi emhlabeni asebenzisa ukunikezwa okujwayelekile okungu-230 V (i-voltage yesigaba) kanye no-400V (amandla kalayini) anezintambo ezimaphakathi ku-50Hz noma ku-60Hz.Noma kungase kube nephethini yegridi ye-Delta yokuthutha amandla kanye nokusetshenziswa kwezimboni kwemishini ekhethekile.Futhi njengomphumela ohambelanayo, iningi lama-solar inverters okusetshenziswa kwendlu noma ophahleni lwezentengiselwano zenzelwe kuleso sisekelo.
Nokho, kukhona okuhlukile, lo mbhalo uzokwethula ukuthi ama-inverter avamile asetshenziswa kanjani kule Gridi ekhethekile.
1. Ukunikezwa kwesigaba sokuhlukanisa
Njenge-United States neCanada, basebenzisa igridi kagesi engu-120 volts ±6%.Ezinye izindawo e-Japan, e-Taiwan, eNyakatho Melika, eMelika Ephakathi nasenyakatho yeNingizimu Melika zisebenzisa amandla kagesi aphakathi kuka-100 V kanye no-127 V ukuze uthole ugesi ojwayelekile wasendlini.Ukusetshenziswa kwendlu, iphethini yokuhlinzeka ngegridi, sikubiza ngokuthi ukunikezwa kwamandla kwesigaba sokuhlukaniswa.
Njengoba amandla kagesi aphumayo amaningi e-Renac Power enesigaba esisodwa solar inverter engu-230V enocingo olungathathi hlangothi, i-Inverter ngeke isebenze uma ixhunywe njengokujwayelekile.
Ngokungeza izigaba ezimbili zegridi yamandla (ama-voltage esigaba se-100V, 110V, 120V noma 170V, njll.) exhuma ku-inverter ukuze ilingane no-220V / 230Vac voltage, inverter yelanga ingasebenza ngokujwayelekile.
Isixazululo sokuxhuma siboniswa ngezansi:
Qaphela:
Lesi sixazululo sifaneleka kuphela ama-inverters e-grid-tieed noma ama-hybrid inverters.
2. 230V Igridi yezigaba ezintathu
Kwezinye izifunda zaseBrazil, awekho amandla kagesi ajwayelekile.Amayunithi amaningi enhlangano asebenzisa ugesi ongu-220 V (izigaba ezintathu), kodwa ezinye - ikakhulukazi enyakatho-mpumalanga - izifunda ziku-380 V (isigaba sesihlahla).Ngisho nangaphakathi kwezinye izifundazwe ngokwazo, ayikho i-voltage eyodwa.Ngokusebenzisa okuhlukile, kungaba ukuxhumana kwe-delta noma ukuxhumana kwe-wye.
Ukuze ilingane nalolu hlelo lukagesi, i-Renac Power inikeza isixazululo ngenguqulo ye-LV Igridi eboshwe 3phase inverters yelanga ye-NAC10-20K-LV, ehlanganisa i-NAC10K-LV, NAC12K-LV, NAC15KLV,NAC15K-LV, engasebenzisa kokubili i-Star. Igridi noma Igridi ye-Delta ngokufaka isibonisi se-inverter (udinga nje ukusetha ukuphepha kwesiguquli njenge-“Brazil-LV”).
I-Bellowing yidatha yedatha ye-MicroLV series inverter.
3. Isiphetho
I-Renac's MicroLV series inverter enezigaba ezintathu iklanywe ngokufaka amandla kagesi aphansi, eklanyelwe ngokukhethekile izinhlelo zokusebenza ezincane ze-PV zezentengiselwano.Ithuthukiswe njengempendulo ephumelelayo ezidingweni zemakethe yaseNingizimu Melika yama-inverter ane-voltage ephansi ngaphezu kuka-10kW, iyasebenza kumabanga ahlukene kagesi wegridi esifundeni, ahlanganisa ikakhulukazi u-208V, 220V kanye no-240V.Nge-inverter yochungechunge lwe-MicroLV, ukucushwa kwesistimu kungenziwa lula ngokugwema ukufakwa kwesiguquli esibizayo esithinta kabi ukusebenza kahle kokuguqulwa kwesistimu.
