6 Frequently Asked Questions about “How to set voltage protection for solar energy”

Do solar PV systems need surge protection?

Recent changes to the BS7671 UK Wiring Regulations 18th Edition in the form of amendment 2 have introduced requirements and considerations for surge protection on both the AC and DC side of a solar PV System.

Do I need a surge protection module for a solar inverter?

It is compulsory to install SPD (surge protection devices) at the ac output of a single phase and three-phase solar inverters. The surge protection module will protect the inverter from high voltages that might be detrimental for the MOSFET and IGBT (internal semiconductors). We recommend the following devices with din-rail mounting.

How to install a surge protection device in a photovoltaic system?

In a photovoltaic system, the placement and quantity of Surge Protective Devices (SPDs) on the DC side are determined by the cable lengths between the solar panels and the inverter. If the cable length is under 10 meters, it is sufficient to install an SPD near the inverter.

How do I protect my PV power supply from a surge?

Use SPDs that are specifically designed for DC applications on the DC side and for AC applications on the AC side is crucial to effective protection. When multiple inverters are connected to a single grid, they can be linked to a single PV surge protective device placed upstream for optimal protection.

Do PV systems need electrical protection?

As the installations and demand for PV systems increases, so does the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors.

Do solar panels need surge protection if lightning strikes?

In the event of lightning strikes, proper surge protection can prevent your valuable PV solar panels and inverters from formidable damage. Installing SPDs on both AC and DC lines on your system is key, especially considering the high cost of inverters within a PV system.
