Class II / Type 2 Surge Protection Device (SPD) for PV/Solar/DC Prosurge PV50 series is a Type 2 (also tested at T1 + T2) SPD (Surge Protective Device) according to IEC 61643-31 or EN 50539-11. It is designed for photovoltaic system DC side protection against the damage from surges caused by lightning and other electrical sources.
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.
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.
There are two different types of DC surge protection device SPD according to IEC 61643-31:2018 and EN 61643-31:2019 (substitute EN 50539-11:2013). Type 1+2 DC Surge Protective Device SPD up to 1500 V DC for photovoltaic PV / solar system, independently tested safety through TUV and CB approval.
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.
