With the generator junction boxes of the GAK6 series, CITEL offers a solution to protect photovoltaic systems of any kind against the effects of lightning and overvoltages. The GAK6 series is designed to protect up to 6 MPP trackers and maximum system voltages (Ucpv) up to 1200 Vdc. Depending on the configuration, the GAK6 meet the normative requirements for all types of buildings with or without external lightning protection system up to lightning protection class I (Iimp = 12.5 kA / pole (10/350)).
