 Depending on the maximum rated fuse current of

the PV module and the local electrical installation

standards, the connection of parallel strings of PV

modules needs to be equipped with suitable fuses

or preventive diodes for circuit protection purposes.

6.2 Electrical connection

To ensure the normal operation of the system, make

sure the polarity of cables is correct when connecting

modules or loads, such as inverters and batteries. If the

PV module is not connected correctly, the bypass

diode may be damaged. Fig. 14 shows how the PV

modules are connected in series and parallel. PV

modules can be wired in series to boost the voltage.

Series connections are made by connecting the wire

from the positive terminal of one module to the

negative terminal of the next module. PV modules can

be wired in parallel to increase the current by

connecting the positive terminal of one module to the

positive terminal of the next module. If a module is not

connected correctly, the bypass diode may be

damaged.

！ATTENTION

 If one PV module string (or PV array) is connected

to another with opposite polarity, irreversible

damage can be caused to the PV module product.

Be sure to confirm the voltage and polarity of each

string before making a parallel connection. If

measurements reveal opposite polarity or a voltage

difference greater than 10V between the strings,

check

their

structural

proceeding with the connection.

 The number of modules connected in series and

parallel should be reasonably designed according to

the system configuration.

 PV modules with different electrical performance

models cannot be connected in one string.

 The system shall use special cables and connectors

for PV system and ensure that all connections are

securely fastened. The cable must be 4mm

AWG) and withstand the maximum possible

open-circuit voltage of the PV system.

 When fixing the cable to the rack, it is necessary to

avoid mechanical damage to the cable or to the PV

configuration
