WARNING If additional PV modules must be installed in string with DualSun modules, their power and current must be equal to those of DualSun panels within the limits of manufacturers' tolerances Wiring in parallel For DualSun modules connected in parallel, a corresponding overcurrent protection must be used. To this end, a DC voltage fuse must be used to avoid reverse current. - Page 21 Never open the junction box The junction box of the DualSun module contains bypass diodes which are in parallel connection with the cell wires. If a hot spot occurs locally on one or more cells, the diode will enter into service to prevent the main current from flowing through the hot cells in order to limit overheating and loss of performance of the module.

Page 22: Bonding And Lightning Protection
It is imperative to refer to the local regulations in force to comply with specific requirements DualSun modules must be bonded with prongs, lugs or other suitable means. Bonding can be done through the holes made for this purpose as part of each module. These holes allow the earth cable to be attached and connected to the equipotential bonding. -
