Photovoltaic fuses protect next-gen integrated solar shingles

07-05-2021 | Littelfuse | Passives

Littelfuse, Inc has launched the 400PV Fuse series, a 2410 size SMD circuit protection component that provides low resistance for photovoltaic (PV) applications.


The series is specially designed to meet the latest trend in solar roofing by allowing PV shingles that integrate the shingles with the PV cells while including protection that meets the UL 248-19 standard for PV applications. This new development helps eliminate mounting separate solar panels over the current roof, enabling the usage of the shingles to work in a dual function – as the protective roofing material while collecting electricity to power the building.


“The 400PV Fuse series innovation enables the next generation of smart home designs to utilise photovoltaic roof shingles to power up everything in a house that requires power,” said Boris Golubovic, vice president, Marketing and Strategy at Littelfuse. “The protection provided by these PV fuses help ensure the operational longevity, maintenance convenience, and safety of solar home and building applications.”
