To protect solar inverters from lightning damage, install appropriate Surge Protection Devices (SPDs) 1 on both AC and DC sides of the system. Select SPDs with voltage ratings matching your system's maximum voltage, and ensure they're properly grounded.
For standard PV power stations, grounding resistance should be below 4 ohms; for large-scale PV power stations or areas with frequent lightning, it should be below 1 ohm.
Why the best practice was used: This document provides consistent criteria for applying lightning protection design, installation, maintenance and inspection into safety programs against the NFPA and DOE requirements.
Upgraded Smart Power Distribution Units (PDUs) provide advanced surge protection, safeguarding telecom equipment from lightning strikes and grid fluctuations. Implementing smart PDUs can reduce downtime by up to 25%, improving overall network reliability and performance.
Bakes battery modules, BMS, power distribution and climate/fire protection into one cabinet for plug-and-play installation and easy transport. Low-profile, space-saving design (15-50 kWh) featuring highly flexible mounting (wall-, pole- or floor-mount) to suit varying site.
What is the most cost-effective way to protect a BESS from lightning? A combination of SPDs, grounding, lightning rods, and shielding offers the best cost-to-protection ratio for BESS facilities. Need help securing your battery storage system? Get in touch with us today.
