The Stringbox BIG is a generator connection box for large systems. There are 5 standard variants with 8, 12, 16, 20 and 24 inputs. All the usual modules for large systems such as DC disconnectors, overvoltage protection, PV fuses, current sensors and string monitoring can be integrated here. The Stringbox BIG is usually planned and assembled to customer specifications. Nothing is left to be desired here. We can even monitor wirelessly - via LoRa WAN! Simply save yourself the trouble of wiring!

Our generator junction box ensure a high level of safety right from the installation stage and guarantee clean and clear wiring (wiring) of PV modules on the roof or in the open field. Several strings often have to be connected in parallel in order to transport suitable power to the inverter at reasonable system voltages. The individual strings are connected directly to the modules in the string box and connected to the inverter input with just two cables (plus and minus). Each generator connection box contains a pressure equalization element as standard for effective protection against condensation.
