Stringbox Easy Duo/Trio Channel

Connection technology PV generator junction box GAK Stringbox Easy Duo/Trio Channel

 

 

Stringbox Easy Duo/Trio Channel

 

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

The Stringbox Easy Duo/Trio Channel is a clever variant which, if it can be used, significantly reduces the costs for the box and installation! There is a wide range of possible applications for this variant. The highlight is that we galvanically isolate the circuit boards internally, enabling two or three different MPP trackers or inverters to be started up with just one box.

String boxes and generator connection box from Q3

Our generator junction boxes ensure a high level of safety during installation 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.
