note
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,
