Basic construction
The BIG string box is a generator connection box for large systems. There are 5 standard versions with 8, 12, 16, 20 and 24 inputs. All the usual modules for large systems such as DC isolators, surge protection, PV fuses and current sensors can be integrated here. The Stringbox BIG is usually planned and constructed according to customer specifications. No wishes remain unfulfilled here.
