I-Solar Branch Connector uhlobo lwesixhumi segatsha lelanga elisetshenziselwa ukuxhuma amaphaneli elanga amaningi ohlelweni lokuphehla amandla elanga eliphakathi nendawo. Amamodeli i-MC4-T kanye ne-MC4-Y amamodeli amabili avamile wokuxhuma amagatsha elanga.I-MC4-T iyisixhumi segatsha lelanga elisetshenziswa ukuxhuma igatsha lephaneli yelanga kumasistimu amabili okukhiqiza amandla elanga. Inesixhumi esimise okwe-T, esinembobo eyodwa exhunywe embotsheni yokukhiphayo yephaneli yelanga nezinye ezimbili ezixhunywe kumachweba okokufaka wezinhlelo ezimbili zokuphehla amandla elanga.I-MC4-Y iyisixhumi segatsha lelanga esetshenziswa ukuxhuma amaphaneli elanga amabili ohlelweni lokuphehla amandla elanga. Inesixhumi esimise okuka-Y, esinembobo eyodwa exhunywe embotsheni yokukhiphayo yephaneli yelanga kanye nezinye izimbobo ezimbili ezixhunywe kuzimbobo zokuphuma kwamanye amaphaneli elanga amabili, bese ixhunywa kumachweba okokufaka wesistimu yokuphehla amandla elanga. .Lezi zinhlobo ezimbili zezixhumi zamagatsha elanga zombili zisebenzisa izinga lezixhumi ze-MC4, ezinezici ezingangeni manzi, izinga lokushisa eliphezulu kanye ne-UV, futhi zifanele ukufakwa nokuxhunywa kwamasistimu okukhiqiza amandla elanga angaphandle.
