Fsolar SafeConnect 2-In/2-Out AC & DC Solar Protection Box – FSPB-2S1640

The Fsolar SafeConnect FSPB-2S1640 serves as a critical safety interface for modern solar power installations, providing dual-sided protection for both DC and AC circuits. This pre-wired solution simplifies installation with clearly marked polarity and integrated solar cables with MC4 connectors, reducing setup time and potential wiring errors. The unit is engineered to work seamlessly within a smart ecosystem, connecting solar panels, grids, and generators to inverters while supporting cloud-based and mobile app monitoring.

On the DC side, the box features high-performance 1000VDC solar gPV type fuse holders equipped with 16A fuses rated for a 33kA breaking capacity. It also includes a GCL-40 Surge Protection Device (SPD) to safeguard against voltage spikes up to 40kA. The AC side is equally robust, utilizing CHINT breakers for input and output protection, including a 40A input breaker with 0.03A residual current protection and a 63A main output breaker. Housed in a durable IP65-rated enclosure, this combiner box is built for long-term outdoor reliability and professional-grade energy management.
