6 FAQs about [Solar cell system low voltage protection]

How to choose a DC surge protection device for solar?

There are three types of DC SPD available for solar. So, you need to choose the DC surge protection device based on your needs. The type 1 surge is designed to handle direct lightning strikes. This device is installed at the primary inlet of the power supply. Additionally, it protects a wide area.

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.

How a DC surge protection device helps a PV system?

So, a DC surge protection device can prevent the current from overflowing into the circuit and save these components from getting damaged. When a power surge occurs, it stops the system from running at its optimal level. Sometimes, it also ruins the PV system components badly.

What is a PV surge protection device (SPD)?

* Four-pole frame with two poles wired parallel. The Bussmann range of PV surge protective devices (SPDs) provides complete system protection with PV ADVANCE to suppress lightning current and PV PRO or PV HEAVY DUTY to suppress overvoltage events. Together, they protect the DC voltage section of a PV system.

Why do solar power systems need surge protection devices?

Sudden power surges lead the PV system components to degrade with time. It gradually reduces the life expectancy of the solar power system. So, a surge protection device will ensure the well-being of these components. Additionally, this device will increase the life expectancy of the solar power system for a longer period.

Do all PV systems need circuit protection?

Globally there is a push for utilizing higher voltages (trending to 1000Vdc and above) to achieve more efficiency. This will mean an even greater need for circuit protection in the future. Do all PV Systems Require Circuit Protection? PV systems that have three or more strings connected in parallel need to have each string protected.
