Stringboxes | Connection technology for PV power plants Q3

We build your box!

Q3's stringboxes are built from a single unit according to your requirements and vary in their equipment (type of housing, number of inputs and outputs, fuse/diode...).

We can optionally equip your box with a (remotely controlled) DC circuit breaker, surge protection (T1+T2/T2), string current measurement, voltage measurement and data transmission. This means that the right technology can be selected for each PV system variant.

• competent and cooperative design support
• quick and easy installation
• PV optimised components
• customised = cost/benefit optimised
• suitable for any module type

Experience, for your safety!

Since 2010, we have been building string boxes as well as AC combiners in all variants and for a wide range of applications, especially in the PV sector - from simple DC disconnect boxes to complex junction boxes for PV power plants with several MW output.
