DC SPD 8.2 TYPE 1+2 M Retrofit

Fronius Primo inverters can be conveniently fitted and ordered with various options such as overvoltage protection.

The surge protection device type 1+2 for direct and indirect lightning strikes is suitable for use with the Fronius Symo 3.0 – 8.2*, Fronius Primo 3.0 – 8.2* and Fronius Symo Hybrid* inverters and therefore fulfils the standard requirement of installing a DC fuse near the inverter ***.

*Please be aware that a surge protective device can only be installed from the following serial numbers onwards: Fronius Primo: 30408866 Fonius Symo: 30408866 Fronius Symo Hybrid: 30408866 ***Since April 2019, DIN VDE 0100-712 requires that a DC 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.
