Photovoltaic (PV) systems are complicated. They are comprised of many components that require various levels of surge protection. The NFPA 780 offers surge protective device (SPD) installation recommendations for solar applications such as requiring SPDs on specific components. To learn the best SPD installation practices, watch this video.
Littelfuse SPD2 Series Type 2 Surge Protection Devices (SPDs) for branch
circuits safeguard components from transient overvoltage or power
surges by limiting the fault current to a load or the unit being
protected. They are designed to prevent equipment damage or downtime
caused by these power fluctuations.
SolaHD’s family of surge protective devices and Active Tracking® Filtering safeguard electrical systems from most transients.
