Fronius DC SPD type 1+2 GEN24

The Fronius DC SPD Type 1+2 GEN24 is a high-performance surge protection device designed specifically for Fronius GEN24 series inverters. It provides reliable protection against both direct and indirect lightning strikes, ensuring long-term safety and stability of photovoltaic systems.

Engineered for installation directly within the inverter connection area, this Type 1+2 SPD meets modern safety standards by combining lightning current protection and surge protection in a single unit. It helps prevent damage to critical system components and reduces downtime caused by electrical surges.

The device is fully compatible with Fronius Symo GEN24 and Primo GEN24 inverters and supports systems with one or two MPPT trackers. With integrated remote signaling, system operators receive automatic alerts via monitoring platforms when protection is activated, allowing fast response and maintenance.
