The PV system should be installed with lightning protection device where there is frequent
lightning activity. To reduce the risk of lightning stroke, the minimum loop area should be applied
when laying the cable.
Figure 8. Circuit Design
When the cables are fixed on the bracket, it is necessary to avoid the mechanical damage
of the cable or the module. Do not press the cable.when fixing cable in a proper way, it should
be fixed with light-resistant cable ties, and avoid direct sunlight and water soaking.
8.2 Grid Electrical System
The DC current of PV system can be converted to AC and connected to the public supply
network. As the policies in different area about connecting PV system to public supply network
are different, please consult the senior system design engineer when designing. Usually, the
installation of this system will need the recognition,acceptance and formal approval of the public
utilities.
8.3 Equipotential Connection
In order to avoid the risk of electric shock or fire hazard, the module frame needs to do the
equipotential connection before the system operation. Please refer to the local safety and
electrical installation standard for the installation requirement.
The correct grounding device is to connect all the metal devices which is not used for
