Mayiko ambiri padziko lapansi amagwiritsa ntchito 230 V (gawo lamagetsi) ndi 400V (voltage ya mzere) yokhala ndi zingwe zopanda ndale pa 50Hz kapena 60Hz. Kapena pakhoza kukhala mawonekedwe a gridi ya Delta yoyendera magetsi ndikugwiritsa ntchito mafakitale pamakina apadera. Ndipo chifukwa chofananira, ma inverters ambiri a dzuwa ogwiritsira ntchito nyumba kapena padenga lamalonda amapangidwa pamaziko oterowo.
Komabe, pali kuchotserapo, chikalatachi chiwonetsa momwe ma inverter omangika a Gridi amagwiritsidwira ntchito pa Gridi yapaderayi.
1. Kugawanika kwa gawo
Monga United States ndi Canada, amagwiritsa ntchito grid voltage ya 120 volts ± 6%. Madera ena ku Japan, Taiwan, North America, Central America ndi kumpoto kwa South America amagwiritsa ntchito ma voltages apakati pa 100 V ndi 127 V kuti apeze magetsi apanyumba. Kuti tigwiritse ntchito m'nyumba, gridi yopangira magetsi, timayitcha kuti magawo agawidwe amagetsi.
Monga ma voliyumu amtundu wamagetsi ambiri a Renac Power single-phase solar inverters ndi 230V okhala ndi waya wosalowerera, Inverter sigwira ntchito ngati ilumikizidwa mwachizolowezi.
Powonjezera magawo awiri a gululi mphamvu (gawo voltages 100V, 110V, 120V kapena 170V, etc.) kulumikiza inverter kuti agwirizane ndi 220V / 230Vac voteji, ndi inverter dzuwa akhoza ntchito bwinobwino.
Njira yolumikizirana ikuwonetsedwa motere:
Zindikirani:
Njira yothetsera vutoli ndi yoyenera kwa ma inverters omwe amamangidwa ndi gridi imodzi kapena osakanizidwa.
2. 230V magawo atatu Gridi
M'madera ena ku Brazil, palibe magetsi okhazikika. Magawo ambiri a federal amagwiritsa ntchito magetsi a 220 V (magawo atatu), koma ena - makamaka kumpoto chakum'mawa - ali pa 380 V (mtengo-gawo). Ngakhale m'maiko ena okha, mulibe mphamvu imodzi yokha. Malinga ndi ntchito zosiyanasiyana, zitha kukhala kulumikizana kwa delta kapena kulumikizana kwa wye.
Kuti agwirizane ndi magetsi otere, Renac Power imapereka yankho ndi LV mtundu wa Grid-womangidwa 3phase solar inverters NAC10-20K-LV mndandanda, womwe umaphatikizapo NAC10K-LV, NAC12K-LV, NAC15KLV,NAC15K-LV, yomwe ingagwiritse ntchito ndi onse Star. Gridi kapena Delta Grid potumiza pa inverter chiwonetsero (ingofunika kukhazikitsa chitetezo cha inverter ngati "Brazil-LV").
Bellowing ndiye tsatanetsatane wa inverter ya MicroLV.
3. Mapeto
Renac's MicroLV mndandanda wamagawo atatu inverter idapangidwa ndi kuyika kwamagetsi otsika, opangidwa makamaka ndi ma PV ang'onoang'ono amalonda. Wopangidwa ngati yankho loyenera ku msika waku South America wofuna ma inverter otsika kwambiri pamwamba pa 10kW, akugwiritsidwa ntchito pamagulu osiyanasiyana amagetsi amagetsi m'derali, omwe makamaka amakhala 208V, 220V ndi 240V. Ndi inverter ya MicroLV, kasinthidwe kachitidweko kumatha kukhala kosavuta popewa kuyika kwa thiransifoma yokwera mtengo yomwe imakhudza kwambiri kusinthika kwadongosolo.
