only be installed from the following serial numbers onwards: Fronius Primo:

fuse be installed on PV systems. In DIN VDE Appendix ZB Section 712.534 DE, it
is stipulated that the surge protective devices be fitted on the DC side as
close to the inverter as possible. By installing the DC SPD 8.2 type 1+2 M
surge protective device, these standard requirements are fulfilled.
