Schematic structure
The Simple string box is equipped with 2 to 6 inputs, which can be externally connected via H4 or MC4 connectors. Internally it is fully wired, with a PCB, which can be equipped with diodes and/or PV fuses. Both outputs are also implemented with H4/MC4 plug connectors. The cable cross-section can be between 2.5 and up to 10/25 mm².
