This document provides essential installation and commissioning instructions for the Huawei SUN2000 150K-MG0 Smart PV Controller. Before installing, ensure you have read the full user manual for detailed safety precautions. Important Safety Warnings: Do not connect loads between the inverter and the AC switch to prevent switch tripping. Each inverter must be equipped with its own dedicated AC output switch; do not connect multiple inverters to the same switch. Ensure the AC switch specifications comply with local standards and company recommendations.
Installation Requirements
Ensure the installation site meets the following clearance requirements for proper heat dissipation and maintenance access:
- Top: ≥ 200 mm
- Sides: ≥ 600 mm
- Front: ≥ 1000 mm
- Bottom: ≥ 600 mm
- Mounting Angle: ≤ 75°
Installing the Device
The device is mounted using the provided bracket. Ensure the mounting surface can support the weight of the unit (98 kg). Follow the steps to secure the bracket to the wall or support structure, then mount the inverter onto the bracket and secure it with the provided M6 screws.
Electrical Connections
Proper cable preparation is critical for system safety and performance:
- PE Cable: Prepare the protective earth cable with a cross-section of 50-240 mm².
- DC Cables: Use the PV connectors delivered with the inverter. Ensure cables are stripped correctly (8-10 mm) and crimped using the specified tools (H4STC0001/CT75A-FJB10).
- AC Cables: Follow the specific stripping and crimping instructions based on the cable diameter (14-66 mm).
- Signal Cables: Connect RS485 cables according to the pinout diagram provided in the manual (RS485A IN/OUT, RS485B IN/OUT).
Power-On and Commissioning
Before powering on, ensure all personnel are wearing appropriate Personal Protective Equipment (PPE). Verify that the DC switches are in the OFF position. Once connected, use the SmartLogger or the mobile app to perform the commissioning process. Monitor the LED indicators on the front panel to verify the system status.
