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.
Transient surges from lightning or switching can damage inverters, batteries and monitoring devices. A solar PV surge protective device withstands continuous DC bias and safely routes energy to ground. For coordinated protection, SPDs should work with over-current devices—see DC Fuse protection in PV arrays.
A DC surge protection device prevents power surge in solar PV systems. It redirects the current from the system's component and prevents it from getting damaged.
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.
