maximum reverse current that a module can withstand, i.e. when one string is in
shade then the other parallel strings of modules will be load by the shade string and
the current will pass through to create a current circuit. Thus based on the
maximum series fuse rating of module and local electrical installation criteria, make
sure the modules strings in parallel for connection need to be assembled with
appropriate string fuse for circuit protection.
d) Open the connection box of the control system and connect the cabled from the PV
arrays to the connection box in accordance with the installation indication of the PV
control systems. The cross-sectional area and cable connector capacity must
satisfy the maximum short-circuit of PV system (For a single component, we
recommended the cross-sectional area of cables is 4mm
2
and the rated current of
connectors is more than 10A), otherwise cables and connectors will become
overheating for large current. Please pay attention the temperature limit of cables is
85
℃
.
e) All module frames and mounting racks must be properly grounded in accordance
with local and national electrical codes. Attach the equipment grounding conductor
to the module frame using the hole and hardware provided. Not that a stainless
steel star washer is used between the ground wire and module frame (see Figure 8
below).This washer is used to avoid corrosion due to dissimilar metals. Tighten the
screw securely.

f) Follow the requirements of applicable local and national electrical codes.
g) These modules contain factory installed bypass 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 9. For
Jinko standard module, L is 900/1200mm; and for customized module, L can be
