Pamene machitidwe osungira mphamvu a dzuwa akuchulukirachulukira, anthu ambiri amadziwa magawo omwe amafanana ndi ma inverters osungira mphamvu.Komabe, palinso magawo ena oyenera kumvetsetsa mozama.Lero, ndasankha magawo anayi omwe nthawi zambiri samanyalanyazidwa posankha ma inverters osungira mphamvu koma ndi ofunikira popanga chisankho choyenera.Ndikuyembekeza kuti mutatha kuwerenga nkhaniyi, aliyense adzatha kusankha bwino pamene akukumana ndi zinthu zosiyanasiyana zosungira mphamvu.
01 Battery Voltage Range
Pakadali pano, ma inverters osungira mphamvu pamsika amagawidwa m'magulu awiri kutengera mphamvu ya batri.Mtundu umodzi umapangidwira mabatire ovotera a 48V, okhala ndi voteji ya batri yomwe nthawi zambiri imakhala pakati pa 40-60V, yomwe imadziwika kuti ma inverters otsika kwambiri a batire.Mtundu winawo umapangidwira mabatire othamanga kwambiri, okhala ndi mitundu yosiyanasiyana ya batire, makamaka yogwirizana ndi mabatire a 200V ndi kupitilira apo.
Malangizo: Pogula ma inverters osungira mphamvu, ogwiritsa ntchito ayenera kulabadira kwambiri ma voliyumu osiyanasiyana omwe inverter ingathe kukhala nawo, kuwonetsetsa kuti ikugwirizana ndi ma voliyumu enieni a mabatire ogulidwa.
02 Mphamvu Yolowera Kwambiri ya Photovoltaic
Mphamvu yowonjezera ya photovoltaic imasonyeza mphamvu yaikulu yomwe gawo la photovoltaic la inverter lingavomereze.Komabe, mphamvu iyi sikutanthauza mphamvu yayikulu yomwe inverter ingathe kuchita.Mwachitsanzo, kwa 10kW inverter, ngati mphamvu yowonjezera ya photovoltaic ndi 20kW, kutulutsa kwa AC kwa inverter kumakhala 10kW yokha.Ngati 20kW photovoltaic array yolumikizidwa, padzakhala kutaya mphamvu kwa 10kW.
Kusanthula: Potengera chitsanzo cha GoodWe inverter yosungirako mphamvu, ikhoza kusunga 50% ya mphamvu ya photovoltaic pamene imatulutsa 100% AC.Kwa inverter ya 10kW, izi zikutanthauza kuti imatha kutulutsa 10kW AC ndikusunga 5kW yamphamvu ya photovoltaic mu batire.Komabe, kulumikiza gulu la 20kW kungawonongebe 5kW ya mphamvu ya photovoltaic.Posankha inverter, musaganizirenso mphamvu yowonjezera yowonjezera ya photovoltaic komanso mphamvu yeniyeni yomwe inverter imatha kugwira nthawi imodzi.
03 Kuchuluka kwa AC Kutha
Pama inverters osungira mphamvu, mbali ya AC nthawi zambiri imakhala ndi zotulutsa zomangika ndi gridi komanso zotulutsa kunja kwa gridi.
Kusanthula: Zotulutsa zomangidwa ndi grid nthawi zambiri sizikhala ndi kuthekera kochulukira chifukwa zikalumikizidwa ndi gridi, pali chithandizo cha gridi, ndipo inverter sifunikira kunyamula katundu payokha.
Kutulutsa kwa gridi, kumbali ina, nthawi zambiri kumafuna kuchulukira kwakanthawi kochepa chifukwa palibe chithandizo cha grid panthawi yogwira ntchito.Mwachitsanzo, inverter yosungirako mphamvu ya 8kW ikhoza kukhala ndi mphamvu yotulutsa mphamvu ya 8KVA, yokhala ndi mphamvu yowoneka bwino kwambiri ya 16KVA mpaka masekondi 10.Nthawi ya 10-sekondi iyi nthawi zambiri imakhala yokwanira kuthana ndi mawotchiwa panthawi yoyambira katundu wambiri.
04 Kuyankhulana
Kulumikizana kwa ma inverters osungira mphamvu nthawi zambiri kumaphatikizapo:
4.1 Kulankhulana ndi Mabatire: Kulankhulana ndi mabatire a lithiamu nthawi zambiri kumachitika kudzera pa CAN, koma ma protocol pakati pa opanga osiyanasiyana amatha kusiyanasiyana.Mukamagula ma inverter ndi mabatire, ndikofunikira kuwonetsetsa kuti zikugwirizana kuti mupewe zovuta pambuyo pake.
4.2 Kuyankhulana ndi Mapulani Oyang'anira: Kuyankhulana pakati pa ma inverters osungira mphamvu ndi nsanja zowunikira ndizofanana ndi ma inverters omangidwa ndi grid ndipo amatha kugwiritsa ntchito 4G kapena Wi-Fi.
4.3 Kuyankhulana ndi Energy Management Systems (EMS): Kulankhulana pakati pa makina osungira mphamvu ndi EMS nthawi zambiri amagwiritsa ntchito mawaya RS485 okhala ndi kulumikizana kwa Modbus.Pakhoza kukhala kusiyana kwa ma protocol a Modbus pakati pa opanga ma inverter, kotero ngati kuyanjana ndi EMS kuli kofunikira, ndikofunikira kulumikizana ndi wopanga kuti mupeze tebulo la Modbus protocol musanasankhe inverter.
Chidule
Magawo a inverter osungira mphamvu ndizovuta, ndipo malingaliro omwe ali kumbuyo kwa gawo lililonse amakhudza kwambiri kugwiritsa ntchito ma inverters osungira mphamvu.
