PHOENIX CONTACT | Solar power - Surge protection for photovoltaic rooftop systems

Surge protection for photovoltaic systems Solar power is an essential source of renewable energy. Decreasing system costs mean that photovoltaic power generation plants are attractive not only from an ecological perspective. They are also extremely competitive from an economic point of view when compared with conventional power generation. In order to provide optimum protection against surge voltages for the various system parts such as PV panels, inverters, and battery storage systems, surge protection must be used.

Directives for lightning and surge protection Certain guidelines must be observed when installing and planning photovoltaic systems. The same also applies to the surge protection of the corresponding system parts. HD 60364-7-712:2016 is a harmonized standard developed by CENELEC on behalf of the European Commission. It describes how to plan and install photovoltaic systems in Europe. The German equivalent is DIN VDE 0100-712. The requirement for surge protection in all building types is specified in VDE 0100-443. The resulting requirement for surge protection on the DC side in accordance with DIN EN 62305-3 Supplement 5 (VDE 0185-305-3 Supplement 5) is also common practice. In an international context, the requirements for selecting the appropriate surge protection, which are described in IEC 61643-32, are very similar in terms of their content. One relevant difference, however, is the implementation of protection on the DC side. In Germany, Country/region Installation of PV Surge protection on the Surge protection on the systems DC side AC side Europe/ internationally HD 60364-7-712 IEC 61643-32 Germany DIN VDE 0100-712 DIN EN 62305-3 Supplement 5 (VDE 0185-305-3 Supplement 5) VDE 0100-443 Standards for the installation of photovoltaic systems and the selection of surge protection for the DC and AC side DC protection is mandatory in the proximity of PV panels. However, surge protection is only additionally required at the inverter if cable lengths exceed 10 m. This is entirely the other way round in IEC 61643-32: Surge protection is mandatory at the inverter, while surge protection in the proximity of PV panels is only additionally required if cable lengths exceed 10 m. Selecting surge protective devices Below we have provided a selection guide indicating which type of surge protection is appropriate based on the conditions at your planned photovoltaic system. Supplement 5 of DIN EN 62305-3 (VDE 0185-305-3 Supplement 5) distinguishes between three different application scenarios that need to be taken into consideration. Detailed information on all three scenarios can be found in the overview on pages 4 and 5. 1. Building without external lightning 2. Building with external lightning 3. Building with external lightning protection protection The separation distance is maintained: The distance “d” is greater than or equal to the separation distance “s” at every point in accordance with DIN EN 62305-3 Supplement 5 (VDE 0185-305-3 Supplement 5). protection The separation distance is not maintained: The distance “d” is less than the required separation distance “s” at at least one point.

Surge protection for home charging stations Suitable surge protection can protect the charging station and the electric vehicle connected in the carport from costly damage. Even if surge protection is already installed in the main distributor box, it may provide insufficient protection in the case of long cable routes to the home charging station, e.g., if the station is located in a carport some distance away. When a suitable surge protective device is installed in sufficient proximity to the home charging station, it can prevent costly damage to the charging station and vehicle. As per VDE 0100-443, surge protection in the main distribution  has been a mandatory requirement for new buildings since 2016. This requirement also applies to extensions, e.g., when retrofitting a home charging station. According to the standard, the protective effect of the surge protective device is sufficient for cable lengths up to 10 m . For cable lengths greater than 10 m, additional protective measures are required directly at the home charging station . ≥10 m With the right surge protection, damage can be prevented. The CHARX protect product family from Phoenix Contact now includes a new IP65- protected surge protection box specifically for this application. It is designed to protect home charging stations with charging power ratings from 11 to 22 kW.
