In perfect time for the Intersolar, HUBER+SUHNER is launching the new intelligent RADOX® SolarBox HM-Blue-Safety. It forms part of a protection system to prevent fires in PV installations, which has been developed in collaboration with the renowned partner MERSEN.
With its new, intelligent junction box HUBER+SUHNER is presenting an innovative premium product for the PV market. The new junction box consists of the basic RADOX® SolarBox HM and an application-specific BlueBox, which can be installed easily via «plug & play».
Integrated smart electronics
The BlueBox incorporates a smart electronics equipped with a safety switch and wired communication. The junction box is one element of a protection system designed for PV installations by the partner company MERSEN. The system allows users to switch modules to a voltage- and current-free state via a master switch for maintenance and repair work. In the event of fire, the safety system also enables the fire department to fight fires on the system without the risk of hazardous
voltages.
To prevent fires breaking out, the entire security system detects arcs on bad contacts and faulty insulation. If an electric arc is detected, the integrated safety switch automatically switches off the individual modules, thus preventing potential damage. The integrated communication unit detects the voltage, current and temperature of the solar module.
Reliable for the entire service life of the system
Thanks to excellent heat dissipation and the patented thermal separation from the module, the BlueBox ensures reliable operation of the electronics throughout the entire service life of the system. It also meets the requirements of Class II and IP67 protection. With a maximum system voltage of 1000 V and current of up to 12.5 A, the box satisfies all PV-related requirements.
Focused on market requirements
With this new product, HUBER+SUHNER is taking a proactive step in anticipation of the safety standards for buildings, sensitive installations and rooftop applications that are due to enter into force in various countries over the coming years. The modular system also provides module manufacturers and installers with a flexible platform that allows the integration of a smart-electronics system of the customer’s choice at a later date.
HUBER+SUHNER already has another BlueBox application under development: the RADOX® SolarBox HM-Blue-AC, which is scheduled to be launched beginning of 2014. The box has an integrated micro- inverter, which converts the solar energy into alternating current directly on the module.
