Amazwe amaningi emhlabeni asebenzisa ukuhlinzekwa okujwayelekile 230 v (i-game Voltage) no-400V (umugqa womugqa) ngezintambo ezingathathi hlangothi ngo-50hz noma nge-60hz. Noma kungahle kube nephethini yegridi ye-delta yokuhamba kwamandla kanye nokusetshenziswa kwezimboni kwemishini ekhethekile. Futhi njengomphumela ohambisanayo, iningi lama-inverters elanga elokusebenzisa indlu noma ophahleni lwezentengiselwano lwenzelwe ngalesi sisekelo.
Kodwa-ke, kukhona okuhlukile, lo mbhalo uzokwethula ukuthi ama-inverters aboshwe ama-grid ajwayelekile asetshenziswa kanjani kule gridi ekhethekile.
1. Ukuhanjiswa kwesigaba okuhlukanisayo
Njenge-United States neCanada, basebenzisa i-grid voltage yama-grounds angama-120 ± 6%. Ezinye izindawo eJapan, eTaiwan, eNyakatho Melika, iCentral America naseNyakatho Melika esebenzisa ama-voltages phakathi kuka-100 v no-127 v kumandla ajwayelekile asekhaya. Ukusetshenziswa kwendlu, iphethini yokuhlinzeka ngegridi, siyibiza ngokuthi yi-Split-Phase Supply.
Njengoba ama-voltage akhipha ama-voltage we-renac Power lingle-Isigaba Sedwalana-Isigaba Somalar-Isigaba Soma-230v ngocingo olungathathi hlangothi, i-inverter ngeke isebenze uma ixhunyiwe njengenjwayelo.
Ngokungeza izigaba ezimbili zegridi yamandla (ama-volitatage angu-100v, 110V, 120v noma ngo-170v, njll.
Isixazululo sokuxhumeka sikhonjiswa njengoba ngezansi:
Qaphela:
Lesi sixazululo silungele kuphela i-Grid-Phaseng Grid-aboshwe noma ama-inverters ahlanganisiwe.
2. 230V ezintathu zesigaba segridi
Kwezinye izindawo zaseBrazil, akukho voltage ejwayelekile. Amayunithi amaningi we-federative asebenzisa ugesi angama-220 v (isigaba esithathu), kepha amanye - ikakhulukazi - izifundazwe - izifundazwe ziku-380 v (isihlahla-isigaba). Ngisho nakwabanye basho ngokwabo, akukho voltage eyodwa. Ngokuya ngokusetshenziswa okuhlukile, kungaba ukuxhumana kwe-delta noma ukuxhumana.
Ukulingana ngohlelo lukagesi, amandla e-renac ahlinzeka ngesisombululo nge-LV version grid-tied grid-tied inverterver 3phase uchungechunge lwe-NAC10-20-LV, i-NAC15KL, olungasebenzisa ukuphepha kwe-inverter (nje I- "Brazil-LV").
I-Boulching yi-datasheet ye-microlv chungechunge inverter.
3. Isiphetho
I-Drac's Microlv Series Tree-Phasen Inverter yakhelwe nge-Voltage Power Power yokufaka, ngokuqondile enzelwe izinhlelo ezincane ze-PV ze-PV. Kuthuthukiswe njengempendulo ephumelelayo ezidingweni zemakethe zaseNingizimu Melika zamandla aphansi amavoluka ngaphezulu kwe-10KW, kusebenza kumabanga ahlukene we-grid voltage esifundeni, okungu-220v no-240v. Nge-Microlv Series Inverter, ukucushwa kwesistimu kungenziwa lula ngokugwema ukufakwa kwe-transformer ebizayo ethinta kabi ukuguqulwa kohlelo.
