The selection and installation of photovoltaic surge protectors
Frequently Asked Questions
What types of PV SPDs does Eprotek recommend for different installations?
For PV installations with an external LPS where separation distances are maintained, a Class II/T2 PV SPD is suggested. For installations where separation distances cannot be maintained, a Class I/T1 PV SPD is recommended.
Where should a PV SPD be installed?
A PV SPD should be installed as close as possible to the equipment protected, such as the inverter.
What should be done if the wiring length between the SPD and the PV generator exceeds 10 meters?
If the length of the wiring between the SPD and the PV generator is greater than 10 meters, a complementary SPD should be installed nearby to protect the PV generator.
What is the recommended total length of connecting cables for SPD installation?
The total length of connecting cables (L1+L2) for SPD installation should be as short as possible, preferably not exceeding 0.5 meters.
What are the characteristics of photovoltaic power generation?
Photovoltaic power generation has the characteristics of simple installation, scalability, stability, and long life.
