Ground installation of PV modules
f) Follow the requirements of applicable local and national electrical codes.
g) These modules contain factory installed by pass diode .If these modules are incorrectly connected to
each other, the bypass diodes, cable or junction box may be damaged.
h) The cable of the junction box is defined as L, as showed below in Figure 11. For Jinko standard full
module L is 900/1200mm, the half
–cut module L is 145/290mm, and the SWAN bifacial module L is
150/250mm. For customized module, L can be based on your condition. Please take the cable length
into consideration before designing the wiring layout.

i) It is recommend to use negatively grounded inverters to avoid the PID effect for non-PID free
modules.
j) If modules are connected in series, the total voltage is equal to the sum of individual voltages. The
recommended as below,
