2. Installation and Commissioning Records

– Wiring diagrams (including transformer connection methods), ground resistance test reports (ground resistance ≤4Ω).

– Communication protocol configuration records (例えば, ModBus address, baud rate).

3. Personnel Qualifications

– Electrician certificates for installers (special operation certificates required in China).

– For PV systems, PV system design plans and grid connection permit documents must be provided.

1. 設置および使用上の注意事項
2. 環境要件

– Installation location must be well-ventilated, avoiding direct sunlight or humid environments (humidity ≤75%).
