Fronius Surge Protection
The plug-in modules allow for fast replacement in the event of a fault. Therefore only the individual module has to be replaced, rather than the entire overvoltage protection. The overvoltage protection is supplied pre-installed and fully cabled**). *) A Fronius Solar.web account is required. **) The option must be ordered at the same time as the inverter. A retrofit version is not available, however the overvoltage arresters can be ordered separately from Fronius.
