We build your box!
Q3 string boxes (generator connection box) are individually manufactured according to your requirements from one copy upwards and vary in their equipment (type of housing, number of inputs and outputs, fuse/diode...).
Optionally we build your box with (remote triggerable) DC circuit breaker, overvoltage protection (T1+T2/T2), string current measurement, voltage measurement and data transmission. Thus, the appropriate technology can be selected for each PV system variant.
