Stringbox Easy

Connection technology Generator connection box Stringbox Easy with overvoltage protection

 

 

Stringbox Easy

 

For larger thin-film systems and systems with crystalline modules

  • Extremely compact and lightweight
  • Quick installation without clamps
  • Flexible fuse protection via fuses and/or diodes
  • Can be equipped with many options (e.g. ÜSS)

 

Areas of application
Small to medium-sized 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.

Basic structure of Stringbox Easy

The generator connection box has 4 to 18 inputs, pluggable from the outside via MC4 connections. It is completely wired internally with a circuit board that can be fitted with diodes and/or PV fuses. The two outputs are also realized via MC4 connectors. The cable cross-section can be between 2.5 and 6 mm². The Stringbox Easy can also 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 - just as you need it!

String boxes and generator connection box from Q3

Our generator junction boxes 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.
