I-Slocable MC4 Iziqhagamshelo zeSola zeNdalo eBungqwabalala

Kwiqondo lokushisa elingaphezulu kwe-70 ° C okanye ukuphakama ngaphezu kwe-2000 yeemitha, iimfuno zokusebenza zokufakelwa kombane ziyahluka ngokuxhomekeka kwiimeko zemozulu.Iindawo ezibuhlungu ezinjengeentlango okanye iintaba zinokubonelela ngeemeko ezifanelekileyo zokukhanya kwemitha kunye nendawo yeenkqubo eziphezulu ze-photovoltaic.I-slocable MC4 isinxibelelanisi selangaipotfoliyo ingqinwe kwizicelo ezinjalo.

Ehlabathini lonke, ii-photovoltaics zikwasetyenziswa kakhulu kwiindawo ezinomngeni.Malunga ne-35% yomhlaba womhlaba yintlango, kwaye abantu baqala ukucinga malunga nendlela yokusetyenziswa ngokufanelekileyo kwezi ndawo, ezinokuthi ziswele amandla oqoqosho kunye neendawo ezinabantu abaninzi, njengokwakha izityalo zamandla e-photovoltaic kwiintlango ezishushu nezomileyo. njengaseMzantsi Melika, eAfrika, kuMzantsi Yurophu nakuMbindi Mpuma.

Ukongeza, iindawo eziphakamileyo zikwayindawo efanelekileyo yokuvelisa amandla elanga.Ngenxa yokuphakama okuphezulu, izityalo zamandla e-photovoltaic zinokuvelisa malunga ne-50 % yombane ngaphezulu kuneendawo ezithafeni.Amanqanaba aphezulu kakhulu emitha yelanga kunye nemozulu engaguqukiyo enelanga ibonelela ngeemeko ezifanelekileyo zokuvelisa amandla aphezulu.Ukongeza kwimimandla ye-alpine yaseYurophu, kwii-Andes zaseMzantsi Melika, izityalo ezininzi ze-photovoltaic zakhiwa ngaphezu kwe-2000 m ngaphezu kolwandle.

ImiGangatho yoKhuseleko yeeNdawo zoBubushushu obuPhezulu

Ngenxa yokukhula okukhawulezayo kwezo marike, ikomiti yezobugcisa ye-IEC TC82 iye yahlula ngokweenkcukacha iimfuno kudederhu lwamaqondo obushushu ahlukeneyo kwaye yamisela ukuseka iimodyuli ezintsha zePV malunga neemeko zesicelo ezinobushushu bokusebenza ukuya kuthi ga kwi-70°C (98th percentile) Umgangatho wokhuseleko IEC 61730. -1.Ukusetyenziswa kobushushu obuphezulu be-ambient njengeendawo eziyintlango, iimfuno ze-IEC TS 63126 ziya kusebenza.

I-IEC TS 63126 icacisa iimfuno ze-thermal kwiimodyuli ze-photovoltaic kunye nezixhobo zazo, ezifana neebhokisi ze-photovoltaic junction kunye nezixhumi ze-photovoltaic, ezinamazinga amabini ahlukeneyo okushisa.Iindidi ezimbini zeemodyuli zePV zezi:

Iqondo lobushushu iKlasi yoku-1: ilingana okanye ngaphezulu kwe-80°C (T98th)

Ubushushu beKlasi 2: ilingana okanye ngaphezulu kwe-90 ° C (T98th).

Ubuncinci beemfuno zobushushu bomda ophezulu (ULT) we-photovoltaic connectors zilandelayo:

I-ULT yezihlanganisi ezisetyenziswe kwiimodyuli ze-PV zeklasi 1: 95 °C ubuncinane

I-ULT yezihlanganisi ezisetyenziswe kwiimodyuli ze-PV zeklasi 2: 105 ° C ubuncinane

IiMfuno zoKhuseleko kuMphakamo oPhezulu

Iimfuno zokulungelelaniswa kokufakelwa kwimigangatho yokhuseleko lwemveliso yombane ngokuqhelekileyo ziyilelwe ukusetyenziswa ukuya kuthi ga kwi-2000 yeemitha ngaphezu komgangatho wolwandle.Ukusetyenziswa komgangatho ophakamileyo, iimfuno zococeko kufuneka zihlaziywe ngenxa yokuba uxinzelelo lomoya olusezantsi lunciphisa ukunyanzeliswa kofakelo lombane ekucoceni i-voltage flashover phenomena.Ke ngoko, ubuncinci bokucocwa kufuneka buphindaphindwe yinto yolungiso kwitheyibhile ye-IEC 60664-1:2020, okanye ingqinwe ngombane wovavanyo oluphezulu.

Kwiminyaka engaphezu kweshumi, inkqubo yoqhagamshelo ye-Slocable PV DC yaziwa ngokuthembeka kwayo okuphezulu kunye nokuzinza.Ngoku, ivavanyiwe kwaye yaqinisekiswa yi-TÜV Rheinland, i-Slocable MC4 ikhonkco yenye ye-photovoltaic connector ukuhlangabezana neemfuno zofakelo kwiinkqubo ze-PV usebenzisa i-module yeqondo lokushisa kwiklasi ye-2. Oku kuthetha ukuba i-Slocable PV connector ivavanyiwe kwaye ibonakaliswe ukuba iyakwazi ukusetyenziswa. kwimozulu ukuya kuthi ga kwi-105°C.
