Stringbox Simple

Anschlusstechnik Stringbox Simple



String Box Simple


For crystalline modules and thin-film systems

  • extremely low structure
  • simple and quick assembly
  • cost effective
  • flexible protection via fuses and/or diodes


Areas of application
Smaller string combinations of modules with a maximum total output current of up to 30 A

Basic construction

The Stringbox Simple has 2 to 6 inputs, pluggable from the outside via H4 or MC 4 connections. It is completely wired internally with a printed circuit board which can be fitted with fuses. The two outputs are also realised via H4 connectors. The wire cross-section can be between 2.5 and up to 10/25 mm².
