Stringbox BIG

 Schematic structure

The Stringbox BIG meets the demands of large scale plants of the megawatt range, e.g. open space installations, large rooftop systems or on factory buildings.

The Stringbox  BIG is a DC distribution box for large scale systems. There are 5 standard versions with 8, 12, 16, 20 or 24 inputs. All standard components for large scale systems, such as DC circuit breakers, overvoltage protectors, PV fuses and current sensors are integrable. The Stringbox BIG is usually planned and manufactured customer-specific. Thus no wishes remain unsatisfied.d with a single box.

  • Competent partners for planning support
  • Individually replaceable
  • Plastic or steel housings possible
  • From standard to highend - we can supply everything

Fields of application

Large systems of the order of megawatts, openfield plants, large roofmounted systems, e.g. on factory buildings.
