Surge protectors for photovoltaic installations in commercial/industrial buildings and car parks

Transient overvoltages and photovoltaic roofs top

Tertiary or industrial sites can integrate medium or high power photovoltaic production directly on the roofs of buildings or via the installation of shaded areas equipped with photovoltaic modules on car parks.

In case of lightning surges, material losses (inverters, PV panels, ...) or operating losses are likely: the implementation of surge protectors (SPD) at the key points of the installation will therefore be necessary or mandatory.
As with any photovoltaic installation, it is required to protect the AC and DC sides of the PV modules from transient overvoltages.
In addition, in order to protect the monitoring systems, surge protectors for data networks must be installed.
