This manual provides essential information for the installation, operation, and maintenance of the GoodWe ET Series 15-30kW commercial and industrial energy storage system. Always ensure that installation and maintenance are performed by qualified electrical technicians. Before starting, verify that the equipment is powered off and that all safety precautions are followed.

System Overview
The system integrates an inverter, battery system, smart meter, and communication module to manage energy flow. It converts solar energy for commercial and industrial use, allowing for self-consumption, battery storage, or grid export.
Installation Requirements
The equipment must be installed in a clean, dry, and well-ventilated environment. Ensure the foundation is level and capable of supporting the system's weight. Maintain adequate clearance around the unit for heat dissipation and maintenance access. Avoid installation in areas with high magnetic fields or direct sunlight.




System Wiring
Proper wiring is critical for system safety and performance. Ensure all DC and AC connections are tight and secure. Use the provided connectors for PV and battery connections. The system supports various grid configurations (TN-S, TN-C, TN-C-S, TT). Always follow the specific wiring diagrams provided in the manual for your system configuration (monobloc or parallel).

Commissioning and Configuration
Before powering on, perform a thorough pre-power check, including verifying all cable connections and ensuring the system is properly grounded. Use the SolarGo app for system configuration, including Bluetooth or WLAN connection, communication settings, and safety standards selection. The app allows for quick setup and monitoring of system parameters.
Maintenance and Troubleshooting
Regular maintenance, such as cleaning and checking connections, is required to ensure system longevity. If a fault occurs, the system will display error codes. Refer to the troubleshooting section in the manual to identify the cause and follow the recommended corrective actions. If the issue persists, contact your local service center.
