Wiring 

Please notice the correct cable connection polarity when installing the modules. If not connected properly, the bypass diode would be destroyed. For bypass diode, rated current of 15A and Maximum reversing voltage of 45V are chosen for Junction box. Ma xim um

Series fuse ra ting : 8A for GES-5Mxxx (xxx=170~200); 13A for GES-6Mxxx

(xxx=205~320) a nd G ES-6Pxxx (xxx=180~300). 

Modules are equipped with Multi-contact connector as electrical connections. Use the National Electric Code to determine system wiring size (refer to NEC clause 310), type and temperature rating of conductors to be connected to the module's connectors. Wiring connected to the module's wiring should be 1X4.0mm2 (minimum) and rated at 90℃ (minimum).



PV modules can be wired in series to increase voltage as shown in figure 7. In this case, the maximum open circuit voltage must not be greater than the specified maximum system volta ge . The volta ge is p rop ortiona l to the numb er of series.



PV mo d ules c a n b e w ired in pa ra llel to in inc rea se th e c urrent a s sho wn in figure 8. In c a se of parallel connection, please take proper measure to block the reverse current flow. Otherwise, the current may easily flow in a reverse direction.
