1.General installation
Do not use modules of different configurations in the same system.
The solar photovolatic array consists of modules connected in parallel, no more than 3
modules can be used in parallel. Modules in parallel can increase the output current of the solar
photovolatic system, especially for
If modules
are connected in parallel, the total voltages is equal to the sum of individual voltages.
If modules used in the solar photovolatic system are not the specified brand of the manufacturer,
it must comply with the electrical requirement.
Modules connected in parallel must use a designated switch junction box, please contact the
supplier for purchasement. The maximum current of the solar photovoltaic system and the
maximum current and voltage capacity of the joints and connective cables should be considerated
during installation.
Connection method A: The distance between the modules is close, no need to use the extension
cord(3 meters), see Fig.52a.
applications requiring high currents, low voltages.
The cross section area of cable and the capacity
of connector must be selected to suit the maximum system short circuit current, Otherwise the
cable and the connector will be overheated under large current.
