3 protection of PV systems with leutron generator connection boxes With the development of ever more powerful inverters Leutron designed a new generation of generator connection boxes, which satisfy the requirements of PV installations the last generation. The new generator connection boxes allow for a very efficient installation by collecting several strings of the PV installation at one single point. This type of installation reduces the process of cabling to a minimum. Projects thus can be flexible, economical and save realiszed. For planning projects there is a check list in the back of these paper. Together with Leutron protection units can be realized economically. Generator connection boxes from Leutron contain no DC switch-disconnector, because the manufactures of inverters place them in their units. String fuses are not a part of the delivery. They can be ordered separately. Installation and mounting of Leutron generator connection boxes is an easy and fast process due to their preassembled bridges, busbars and internal cabling. They have following configuration: Cable entry: 2x 6 mm² Blind plugs, blind discs Plug-in terminals, max. 16 mm² Cable entries from botton All generator connection boxes have following characteristics: To be applied in unprotected installation outside Protection class II Operating temperature range: C UV resistance Material: polycarbonate UL 746 CSV Colour: grey, RAL 7035 Degree of protection: IP 66/67 The selection of generator connection boxes complies with: Open circuit voltage of the strings Number of the strings Number of the MPP trackers Please note by selection of surge protection device: Surge arrester type 2 /class II is used, if the seperation distance to the external lightning protection sytems is not realized or buildings do not have an external lightning protection. Combined SPD type 1+ type 2 /class I+II is used, if the seperation distance of the PV system is not realized.* Remark: Protection of data lines are not considered because of its different interfaces. *More informations about selection and application of lightning and surge protection are described in following standards: VDE , Beiblatt 5 Blitz- and Überspannungsschutz for PV-Stromversorgungssysteme Pre-standard CLC/TS :2010 (VDE V ) Überspannungschutz für den Einsatz in Photovoltaik-Installationen Leutron GmbH Gaussstr. 2 Germany D Leinfelden-Echterdingen phone
