Stringbox Simple
For crystalline modules and thin-film systems
- Extremely low structure
- Quick and easy installation
- inexpensive
- Flexible fuse 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 structure of Stringbox Simple
The generator connection box has 2 to 6 inputs and can be plugged in from the outside via H4 or MC 4 connections. The box is completely wired internally with a circuit board that can be fitted with fuses. The two outputs are also realized via MC4 connectors. The cable cross-section can be between 2.5 and up to 10/25 mm² - just as you need it!
String boxes and generator connection box from Q3
Our generator junction box ensure a high level of safety right from the installation stage and guarantee clean and clear wiring (wiring) of PV modules on the roof or in the open field. Several strings often have to be connected in parallel in order to transport suitable power to the inverter at reasonable system voltages. The individual strings are connected directly to the modules in the string box and connected to the inverter input with just two cables (plus and minus). Each generator connection box contains a pressure equalization element as standard for effective protection against condensation.
