Stringbox Easy 3G


Schematic structure

We configurate your string box according to your plant system. You can choose from 4 till 18 strings per box. Depending on the DC current and the used modules we specify the required fuses and/or diodes. In case of a long way to the inverter it is possible to set two H4 connector (10 mm²) at the string box’s output. It is also possible to clamp the output already inside the box (up to 35 mm²).

  • Compact and light construction
  • Easy and quick mounting
  • Flexible protection with  fuses and/ or diodes
  • Many option available, e.g. overvoltage protection
  • Duo/ Trio Channel version available

Fields of application

Small to medium-size 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 output current of the string combination does not exceed 90 A.




An overview of the most important features:

Our Connection Technology

Stringbox Simple

Cost-effective and light-weight string box with 2 up to 5 inputs for small crystalline modules and thin-film installations.

Stringbox Easy 3G

Compact and lightweight string box for small to medium-sized string combinations and thin-film systems of all types up to 18 inputs.

Easy Duo/Trio Channel

String box due to the electrically isolated PCBs which two oder three different MPP trackers or inverters can be operated with a single box.

Stringbox BIG

Generator connection box for large systems of the order of megawatts, openfield plants, large roofmounted systems, e.g. on factory buildings.


Customized AC Box for connecting up to 20 inverters project example REC Romania.
