3. Wiring and connection
a) Before this procedure, please read the operation instructions of the PV system carefully.
Make wiring by Multi-connecting cables between the PV modules in series or parallel
connection, which is determined by user’s configuration requirement for system power,
current and voltage.
b) PV modules connected in series should have similar current, and modules must not be
connected together to create a voltage higher than the permitted system voltage. The
maximum number of modules in series depends on system design, the type of inverter used
and environmental conditions.
c) The maximum fuse rating value in an array string can be found on the product label or in the
product datasheet. The fuse rating value is also corresponding to the 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 loaded by the shaded string and the current will pass through to
create a current circuit. Based on the maximum series fuse rating of module and local
electrical codes and standards, make sure the modules strings in parallel are protected with
the appropriate in-line string fusing.
d) Open the combiner box of the control system and connect the conductor from the PV arrays
to the combiner box in accordance with the the design and local codes and standards. The
cross-sectional area and cable connector capacity must satisfy the maximum short-circuit of
the PV system (for a single component, we recommended that the cross-sectional area of
cables be 4mm
2
and the rated current of connectors be more than 10A), otherwise cables
and connectors will become overheating for large current. Please pay attention to 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. Note that a stainless steel star washer is used
between the ground wire and module frame (see Figure 7 below).This washer is used to
avoid corrosion due to dissimilar metals. Tighten the screw securely.
