Figure 12 Schematic diagram of electrical
connection
•
If one set of arrays is connected to
another with the opposite polarity, it
will cause irreparable damage to the
product. Before connecting in parallel, be sure to
confirm the voltage and polarity of each column.
If the measurement finds that the polarity
between the columns is reversed or the voltage
difference is greater than 10V, you must check
the structure and configuration before making the
connection.
•
The number of photovoltaic modules in series
and parallel must be designed reasonably
according to the system configuration.
•
Photovoltaic modules of different electrical
performance models cannot be connected in a
string.
•
Special solar cables and connectors should be
used in the system, and all connections should
be securely tightened. The cable size should be
4mm2 (12 AWG) and must be able to withstand
the maximum open circuit voltage of the
photovoltaic system.
•
When the cable is fixed on the bracket, it is
necessary to avoid mechanical damage to the
cable or photovoltaic module, and do not press
the cable with force. To fix the cable through the
proper way, a specially designed tying coil and
wire clip must be used to fix it on the bracket.
Avoid direct sunlight and water soaking cables.
•
Please keep the connector dry and clean, and
make sure that the nut of the connector is
tightened before connecting. Do not connect the
connector when it is found that the connector is
wet, dirty, or in other bad conditions. Avoid direct
sunlight and immersion of the connector in water.
Avoid the connector falling on the ground or roof.
•
When the photovoltaic module is in a live state,
please do not plug or unplug the connector.
When it is necessary to open the connector,
ensure that the photovoltaic module is in a
non-working state, and must use professional
unlocking tools and safety protection measures. It
is forbidden to pull or damage the locking
structure.
•
The junction box of the photovoltaic module
contains bypass diodes connected in parallel to
the battery string of the photovoltaic module. The
bypass diode in the junction box can avoid the
degradation of photovoltaic module performance
caused by shading or covering. Please refer to
the junction box diode specifications provided in
the relevant product specifications.
•
When a local hot spot phenomenon occurs due to
partial shading or covering of the photovoltaic
module, the diode in the junction box will start to
work, so that the photovoltaic module current will
no longer flow through the hot spot cell, thereby
limiting the heating and performance loss of the
photovoltaic module. When you suspect or find
that the diode is malfunctioning, please contact 8
