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 cable 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
overheated from large current. Please pay attention: the temperature limit of
cables is 85
℃
and the temperature limit of connector 105
℃
.
e) All module frames and mounting racks must be properly grounded in accordance
with local and national electrical codes. It is recommended that the applied torque
is 2.3 to 2.8Nm.
Jinko modules can be grounded using third party ground washers or clip devices

as long as the products are approved for grounding
metallic frames of PV modules.
Alternate grounding options built into the racking system are acceptable so long as
they have been UL approved.
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 module shall wire in accordance with the NEC, the grounding method of the
frame of arrays shall comply with the NEC, article 250.
i) It is recommended that the screw be tightened to a torque of about 8 Nm.
j) The cable of the junction box is defined as L1, as showed below. For Jinko
standard module, L1 is 900 /1200mm; and for customized module, L1 can be
based on your condition, take the cable length into consideration before designing
the wiring layout.
k) Jinko Solar requires the negative grounding of the inverter when a system is
installed with standard (non-Eagle line) PV solar modules. Alternatively, a
