Product Functions
◆Serves as the main distribution and connection point between the PV system and the power grid.
◆Connects centralized inverters or AC combiner boxes to step-up transformers.
◆Provides secondary lightning protection.
◆Supports additional functions like metering, protection, and remote control per customer requirements.
Applicable Environment
◇Ambient Temperature: -20℃ to +40℃ (24h avg≤+35℃).
◇Relative Humidity: ≤70% at 40℃; allows for higher humidity at lower temperatures.
◇Altitude: ≤3000 meters.
◇Installation Slope: Vertical tilt≤5°.
◇Atmosphere: Clean air, free from explosive or corrosive substances.
◇Note: Consult the manufacturer for conditions outside these ranges.
Product Highlights
◆High Compatibility: Suitable for various ground-mounted PV system configurations.
◆Flexible Configuration: Incoming/outgoing lines can be connected via circuit breakers or directly; busbars are electroplated/purified.
◆Robust & Safe: Features high breaking capacity, good dynamic/thermal stability, and a simple, secure structure.
◆Dual Protection: Available in IP40 (indoor) and IP65 (outdoor) protection levels.
◆Convenient Maintenance: Designed for easy on-site wiring and service.
◆Standards Compliant: Meets national GB and international IEC standards.
Installation Instructions
◇Install on a foundation of concrete-embedded channel steels per electrical equipment codes and design drawings.
◇Secure each cabinet by welding or bolting to the channel steel.
◇For multi-cabinet installations, follow standard distribution cabinet alignment guidelines.
◇Ensure reliable connection of all inter-cabinet wiring, sampling points, and grounding protection lines.
