6 FAQs about [Solar low voltage protection system]

What is a good voltage protection level for a solar array?

To have a protective effect, an SPD’s voltage protection level (Up) should be 20 % lower than the dielectric strength of the system’s terminal equipment. It is important to use an SPD with a short circuit withstand current greater than the short circuit current of the solar array string that the SPD is connected to.

Why do solar panels have a voltage surge?

The voltage surge can occur for multiple reasons, such as lightning or internal changes in voltage use. So, as solar PV systems are susceptible to damage, voltage surges destroy the solar power’s photovoltaic (PV) system components.
