Protect the PV panels and the inverter against lighting and power surges. Tor reduce the risk for damages, surge protection should also be installed on the DC side.
Protect the PV installation on the DC side with the correct surge protection device.
Solar panels are typically placed high and open, making them particularly exposed to lightning – one of the most common reasons why a system do not to function properly. In addition, it must be taken into account that other transients, which normally occur in the grid, can damage both solar panels and inverters if proper protection is not provided.
Therefore, a surge protection device is a sensible investment that all PV installations should be equipped with. In most cases, surge protection is recommended for PV installations on both the AC and DC side. Without surge protection on the DC side, solar panels and inverters do not have adequate protection against lightning and surges.
Our product range consists of Type 1/2 combination lightning/surge arrester and Type 2 Surge arrester for installations up to 1000VDC. If the building is equipped with an external lightning rod a type 1/2 combination lightning/surge arrester is required. For buildings without external lightning protection, Type 2 surge arrester can be used.
