Guhindura MC4 Imirasire y'izuba kubidukikije bikaze

Ku bushyuhe bw’ibidukikije hejuru ya 70 ° C cyangwa ku butumburuke buri hejuru ya metero 2000, ibisabwa mu mikorere y’amashanyarazi biratandukana bitewe nikirere.Ibidukikije bikaze nk'ubutayu cyangwa imisozi birashobora gutanga uburyo bwiza bwo kurasa hamwe n'umwanya wa sisitemu yo gufotora neza.Umuyoboro wa MC4 uhindagurikaportfolio yemejwe kubikorwa nkibi.

Kwisi yose, amafoto yerekana amashusho nayo arakoreshwa cyane mubidukikije bigoye.Hafi ya 35% yubutaka bwisi ni ubutayu, kandi abantu batangiye gutekereza kuburyo bwo gukoresha neza utwo turere, ubundi bikaba bidafite ubushobozi bwubukungu n’ahantu hatuwe cyane, nko kubaka amashanyarazi y’amashanyarazi mu butayu bushushe kandi bwumutse nkubwo nka Amerika y'Epfo, Afurika, Uburayi bw'Amajyepfo n'Uburasirazuba bwo hagati.

Byongeye kandi, ubutumburuke buke nabwo ni ahantu heza ho kubyara ingufu z'izuba.Kubera ubutumburuke buri hejuru, amashanyarazi y’amashanyarazi arashobora kubyara amashanyarazi agera kuri 50% kuruta mu bice bisanzwe.Urwego rwo hejuru cyane rw'imirasire y'izuba hamwe n'izuba rihoraho bitanga ibihe byiza kubyara ingufu nyinshi.Usibye uturere twa alpine two mu Burayi, muri Andes yo muri Amerika y'Epfo, hubakwa amashanyarazi menshi kandi menshi y’amashanyarazi hejuru ya m 2000 hejuru y’inyanja.

Ibipimo byumutekano kubushyuhe bwo hejuru

Bitewe n’iterambere ryihuse ry’amasoko, komite tekinike ya IEC TC82 yatandukanije mu buryo burambuye ibisabwa ku bipimo bitandukanye by’ubushyuhe bw’ibidukikije maze ishyiraho uburyo bushya bwa PV bwo gukoresha ibintu bifite ubushyuhe bukora bugera kuri 70 ° C (98th ijana) IEC 61730 -1.Kubushyuhe bwo hejuru bwibidukikije nko mu butayu, ibisabwa bya IEC TS 63126 bizakoreshwa.

IEC TS 63126 isobanura ibyerekeranye nubushyuhe bukenewe kuri moderi ya Photovoltaque nibiyigize, nkibisanduku bifotora bifotora hamwe nifoto ifotora, hamwe nubushyuhe bubiri butandukanye.Ibyiciro bibiri kuri PV module ni:

Ubushyuhe Icyiciro cya 1: bingana cyangwa hejuru ya 80 ° C (T98th)

Ubushyuhe Icyiciro cya 2: bingana cyangwa hejuru ya 90 ° C (T98th).

Ibisabwa byibuze kubushyuhe bwo hejuru (ULT) bwamafoto ya fotora ni ibi bikurikira:

ULT kubahuza ikoreshwa kuri PV modules yicyiciro 1: 95 ° C byibuze

ULT kubihuza byashyizwe kumurongo wa 2 PV module: 105 ° C byibuze

Ibisabwa byumutekano kurwego rwo hejuru

Ibisabwa byo guhuza ibikorwa byokwirinda mubipimo byumutekano wibicuruzwa byamashanyarazi mubisanzwe bigenewe gukoreshwa kugera kuri metero 2000 hejuru yinyanja.Kubisabwa murwego rwo hejuru, ibisabwa byemewe bigomba gusubirwamo kuko umuvuduko wumwuka muke ugabanya ubukana bwamashanyarazi kugirango ibintu bishoboke.Kubwibyo, gukuraho byibuze bigomba kugwizwa nimpamvu yo gukosora kumeza ya IEC 60664-1: 2020, cyangwa kugenzurwa na voltage yo hejuru yikigereranyo.

Kumyaka irenga icumi, sisitemu yo guhuza PV DC izwiho kwizerwa no gushikama.Noneho, byageragejwe kandi bigenzurwa na TÜV Rheinland, umuhuza wa Slocable MC4 numwe mubahuza fotovoltaque kugirango wuzuze ibisabwa kugirango ushyire muri sisitemu ya PV ukoresheje icyiciro cy'ubushyuhe bwa module 2. Ibi bivuze ko umuhuza wa Slocable PV wageragejwe kandi ugaragara ko ushobora gukoreshwa. mu kirere kigera kuri 105 ° C.
