IP Ratings for Energy Storage Connectors: Understanding Protection Levels
Sarah Liu April 28, 2026 1 min readEngineering

Ingress Protection (IP) ratings defined by IEC 60529 indicate sealing effectiveness against foreign bodies and moisture.
Common IP Ratings for ESS Connectors
- **IP20** - Internal use only, inside sealed enclosures
- **IP65** - Dust-tight, protected outdoor locations
- **IP67** - Dust-tight with temporary immersion, most common for outdoor ESS
- **IP6K9K** - High-pressure/high-temperature wash, heavy-duty applications
Selection Guidelines
Consider installation location, weather conditions, cleaning requirements, temperature extremes, and salt spray exposure.
Our connector portfolio spans IP20 to IP6K9K for every application requirement.
