Q3 Easy - String Box
The Stringbox Easy has 4 to 18 inputs, pluggable from the outside via H4 connections. It is completely wired internally with a printed circuit board which can be fitted with diodes and/or PV fuses. The two outputs are also realised via H4 connectors. The wire cross section can be between 2.5 and 6 mm². Furthermore, the Stringbox Easy can be equipped with a second output or a cable cross-section of up to 35 mm² can be connected via screw terminals mounted on top-hat rails.
For larger thin-film systems and systems with crystalline modules
- fast assembly without clamps
- flexible protection via fuses and/or diodes
- can be equipped with many options (e.g. Overvoltage Protection)
Areas of application
Small to medium string combinations with crystalline modules with a maximum total output current of up to 90 A. Thin-film systems of all types in which the string combinations do not exceed an output current of 90 A.
