Ka ntshetsopele ya thekenoloji ya mojule wa Cell le PV, dithekenoloji tse fapaneng tse kang half cut cell, shingling module, bi-facial module, PERC, jj. Matla a tlhahiso le hona joale tsa mojule o le mong li eketsehile haholo. Sena se tlisa litlhoko tse phahameng ho li-inverters.
1.High-Power Modules e hlokang ho Fetoha ho Fetisisa ha Hona Joale ea Li-Inverters
Li-module tsa Imp tsa PV li ne li le haufi le 8A nakong e fetileng, kahoo boholo ba hona joale ba motlakase oa motlakase bo ne bo le haufi le 9-10A. Hona joale, Imp ea 350-400W li-modules tsa matla a phahameng li fetile 10A tse hlokahalang ho khetha inverter e nang le palo e kholo ea 12A ea hona joale kapa e phahameng ho kopana le PV module ea matla.
Tafole e latelang e bonts'a mekhahlelo ea mefuta e mengata ea li-module tsa matla a phahameng tse sebelisoang 'marakeng. Re ka bona hore Imp ea module ea 370W e fihla ho 10.86A. Re tlameha ho etsa bonnete ba hore boholo ba hona joale ba ho kenya letsoho ba inverter ho feta Imp ea mojule oa PV.
2.Ha matla a mochine o le mong a ntse a eketseha, palo ea likhoele tse kenang tsa inverter e ka fokotsoa ka mokhoa o nepahetseng.
Ka ho eketseha ha matla a li-module tsa PV, matla a khoele e 'ngoe le e' ngoe le 'ona a tla eketseha. Tlas'a karo-karolelano ea matla a tšoanang, palo ea Likhoele Tse Kenyelitsoeng ka MPPT e tla fokotseha.
Phaello e phahameng ea hona joale ea Renac R3 Note Series 4-15K inverter ea mekhahlelo e meraro ke 12.5A, e ka finyellang litlhoko tsa li-module tsa PV tse matla.
Ho nka 370W modules e le mohlala ho lokisa 4kW, 5kW, 6kW, 8kW, 10kW tsamaiso ka ho latellana. Lintlha tsa bohlokoa tsa li-inverters ke tse latelang:
Ha re lokisa tsamaiso ea letsatsi, re ka nahana ka DC oversize. Mohopolo oa DC oversize o amohetsoe haholo ka moralo oa sistimi ea letsatsi. Hajoale, lifeme tsa motlakase tsa PV lefatšeng ka bophara li se li fetisitse boholo bo pakeng tsa 120% le 150%. E 'ngoe ea mabaka a ka sehloohong a ho fetisa jenereithara ea DC ke hore matla a tlhōrō ea li-modules hangata ha a finyelloe ka nnete. Libakeng tse ling moo ho nang le mahlahahlaha a sa lekaneng, ho feteletsa ka mokhoa o nepahetseng (ho eketsa bokhoni ba PV ho eketsa lihora tsa mojaro o felletseng oa sistimi ea AC) ke khetho e ntle. Moralo o motle ka ho fetesisa o ka thusa sistimi hore e be haufi le ts'ebetso e felletseng le ho boloka sistimi e le maemong a phetseng hantle, e leng se etsang hore matsete a hau a be le molemo.
Tlhophiso e khothaletsoang ke e latelang:
Hafeela matla a maholo a potoloho a bulehileng a mohala le boholo ba DC hona joale a le ka har'a mamello ea mochine, inverter e ka sebetsa ho hokahanya le marang-rang.
1.Maximum DC ea hona joale ea khoele ke 10.86A, e ka tlaase ho 12.5A.
2.Bophahamo bo phahameng ba motlakase o bulehileng oa khoele ka har'a mefuta ea MPPT ea inverter.
Kakaretso
Ka ntlafatso e tsoelang pele ea matla a module, baetsi ba li-inverter ba hloka ho nahana ka ho lumellana ha li-inverters le li-module. Haufinyane, li-module tsa 500W+ PV tse nang le hona joale tse phahameng li kanna tsa ba tsona tse ka sehloohong 'marakeng. Renac e fihlela tsoelo-pele ka boqapi le theknoloji 'me e tla tsebisa lihlahisoa tsa morao-rao ho tsamaisana le mojule oa PV oa Power PV.
