Ka nts'etsopele ea theknoloji ea mojule oa Cell le PV, litheknoloji tse fapaneng tse kang half cut cell, shingling module, bifacial module, PERC, joalo-joalo li phahamisitsoe ho tse ling. Matla a tlhahiso le hona joale tsa mojule o le mong li eketsehile haholo. Sena se tlisa litlhoko tse phahameng ho li-inverters.
Li-Module tsa Matla a Phahameng a Hlokang Boemo bo Phahameng ba Hona Joale ba Li-Inverters
Li-module tsa Imp tsa PV li ne li le haufi le 10-11A nakong e fetileng, ka hona, boholo ba motlakase oa motlakase o ne o le haufi le 11-12A. Hajoale, Imp ea 600W + li-module tsa matla a phahameng li fetile 15A tse hlokahalang ho khetha inverter e nang le palo e kholo ea 15A e kenang 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 600W bifacial module e fihla ho 18.55A, e leng ntle le moeli oa boholo ba li-inverters tsa likhoele 'marakeng. Re tlameha ho etsa bonnete ba hore boholo ba hona joale ba ho kenya letsoho ba inverter bo boholo ho feta Imp ea module ea PV.
Ha matla a mojule o le mong a ntse a eketseha, palo ea likhoele tse kenang tsa inverter e ka fokotsoa ka nepo.
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.
Ke Tharollo efe ea Renac e ka fanang ka eona?
Ka April 2021, Renac e ile ea lokolla letoto le lecha la li-inverters tsa R3 Pre series 10 ~ 25 kW. E sebelisa theknoloji ea morao-rao ea motlakase oa motlakase le thekenoloji ea moralo oa mocheso ho eketsa boholo ba motlakase oa motlakase oa DC ho tloha ho 1000V ea pele ho ea ho 1100V, e lumella tsamaiso ho hokahanya haholoanyane. liphanele, le tsona li ka boloka litšenyehelo tsa cable. Ka nako e ts'oanang, e na le matla a 150% DC oversize. Boemo bo phahameng ba ho kenya letsoho ba letoto lena la inverter ke 30A ka MPPT, e ka finyellang litlhoko tsa li-module tsa PV tse matla.
Ho nka 500W 180mm le 600W 210mm bifacial modules e le mohlala ho lokisa 10kW, 15kW, 17kW, 20kW, 25kW systems ka ho latellana. Lintlha tsa bohlokoa tsa li-inverters ke tse latelang:
Hlokomela:
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:
Ho ea ka lipalo, li-inverters tsa Renac li ka tsamaisana hantle le liphanele tse peli tsa 500W le 600W.
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 210mm wafer 600W+ PV tse nang le hona joale e phahameng li kanna tsa ba tsona tse ka sehloohong 'marakeng. Renac e fihlela tsoelo-pele ka boqapi le theknoloji 'me e tla tsebisa lihlahisoa tsohle tse ncha ho tsamaisana le li-module tse phahameng tsa Power PV.
