6. Electrical installation

Modules are supplied with cables and connectors to be used for system electrical

connections. It is not recommended to use modules with different configurations and

electrical characteristics in the same system.

Modules can be connected in series to obtain a high operating voltage. The system voltage is

equal to the sum of the voltage of each module. Modules can also be connected in parallel to

obtain a high operating current. The system current is equal to the sum of the current of each

string of modules.

Under normal conditions, a module is likely to experience conditions that produce more

current and/or voltage than reported at standard test conditions. The suggested fuse must be

used for overcurrent protection. Accordingly, the values of Isc and Voc marked on this module

should be multiplied by a factor of 1.25 when determining component voltage ratings,

conductor ampacities, fuse sizes, and size of controls connected to the PV output.

The maximum number of series connected modules depends on system design, the type of

inverter used and environmental conditions. It should be noted that modules must not be

connected together to create a voltage higher than the permitted system voltage. There is no

limitation on the number of modules that can be connected in parallel; the number of modules

is determined by system design parameters such as current or power output.

The maximum number of modules to be installed in series on the installation, N(max), is

calculated using the following formula:
