Stringbox Easy Duo/Trio Channel
For larger thin-film systems and systems with crystalline modules
- fast assembly without clamps
- flexible protection via fuses and/or diodes
- can be equipped with many options (e.g. ÜSS)
Areas of application
Small to medium 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 construction
The Easy Duo/Trio Channel string box is a clever variant which, when it can be used, significantly reduces the cost of the box and installation! There is a wide range of possible applications for this variant. The trick is that we galvanically separate the circuit boards internally, thus enabling two or three different MPP trackers or inverters to be started up, and all this with just one box.
