Overview
The TPK-40-PVxxx series is a high-performance DC surge protective device (SPD) designed for photovoltaic (PV) installations operating between 500 VDC and 1500 VDC. Th SPDs safeguard the DC side of solar power systems from direct and indirect lightning-induced surges. Installed between PV modules and inverters, they ensure reliable overvoltage suppression using high-energy MOV components. Featuring full protection modes (+ to -, + to PE, – to PE), the TPK-40-PVxxx series is optimized for solar farms, rooftop installations, and off-grid systems with remote signaling and compact DIN-rail mount design.
