4. Setup and Installation
4.1 Unboxing and Inspection
Upon receiving your Powerwall battery, carefully unbox it. The battery is secured in a wooden box with EVA foam for protection during transit. Inspect the battery for any signs of physical damage. Ensure all accessories, including the parallel power cable and user manual, are present.
Video 4.1: Product packaging and unboxing process, showing the secure wooden box and foam protection.
4.2 Physical Placement
The battery dimensions are 500mm (L) x 700mm (W) x 730mm (H) and it weighs 279KG. Choose a stable, dry, and well-ventilated location for installation, away from direct sunlight, heat sources, and flammable materials. Ensure adequate clearance around the unit for ventilation and access.
4.3 System Connection
The SOEC Powerwall is designed to integrate with solar power systems and inverters for household energy storage. The general connection involves solar panels (DC) and/or a power grid/electric generator (AC) feeding into an inverter, which then charges the battery (DC) and supplies AC power to household appliances.
Figure 4.2: Household Energy Storage System Diagram, illustrating connections between solar, grid, inverter, battery, and household loads.
Connect the battery to your compatible inverter using appropriate cables. Ensure correct polarity for all connections. The battery features positive (+) and negative (-) terminals, as well as communication ports (RS485, CAN, RS232) for data exchange with the inverter or monitoring system.

4.4 Parallel Connection
For increased energy storage capacity, multiple SOEC Powerwall units can be connected in parallel. The system supports up to 15 units in parallel, allowing for a total capacity of up to 450KWH. Use the provided parallel power cable and ensure proper communication setup between all units and the master inverter.
5. Operation
Once installed and connected, the SOEC Powerwall battery operates in conjunction with your inverter to manage energy flow. The built-in BMS automatically handles charging, discharging, and protection functions.
5.1 Initial Power-Up
Follow the power-up sequence recommended by your inverter manufacturer. Typically, this involves connecting the battery, then the inverter, and finally activating the system. The battery's display panel will show operational status.
5.2 Monitoring
You can monitor the battery's status, including voltage, current, temperature, and state of charge, through the inverter's interface or by connecting the battery's BMS to a computer via RS485, CAN, or RS232 protocols. Refer to your inverter and BMS software manuals for detailed monitoring instructions.
6. Maintenance
The SOEC LiFePO4 Powerwall battery is designed for minimal maintenance. However, adhering to the following guidelines will ensure optimal performance and longevity:
- Environmental Conditions: Ensure the battery operates within the specified temperature ranges:
- Charging: 0°C to 45°C
- Discharging: -20°C to 60°C
- Storage: -20°C to 45°C
- Cleaning: Keep the battery unit clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
- Connections: Periodically check all electrical connections to ensure they are secure and free from corrosion.
- Ventilation: Ensure that the ventilation openings are not obstructed to prevent overheating.
- Long-Term Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC) and stored within the recommended temperature range. Check the charge level periodically and recharge if necessary to prevent deep discharge.
7. Troubleshooting
If you encounter issues with your SOEC Powerwall battery, consider the following general troubleshooting steps:
- No Power Output: Check all cable connections, ensuring they are secure and correctly polarized. Verify that the inverter is functioning correctly and that the battery's power switch is ON.
- Charging Issues: Confirm that the solar panels or grid connection to the inverter are operational. Check the inverter settings for charging parameters. Ensure the ambient temperature is within the specified charging range.
- Communication Errors: Verify that the communication cables (RS485, CAN, RS232) are correctly connected between the battery and the inverter/monitoring device. Consult the inverter and BMS software manuals for specific communication setup and diagnostic tools.
- Unusual Sounds or Smells: Immediately disconnect the battery from all power sources and contact technical support if you notice any unusual sounds, smells, or smoke.
- System Overload: If the system shuts down due to overload, reduce the connected load and restart the system. The BMS will protect the battery from excessive discharge current.
For complex issues, refer to your inverter's manual or contact SOEC technical support.
8. User Tips
- Inverter Compatibility: The SOEC Powerwall is designed to be compatible with a wide range of inverter brands. If you have an existing solar inverter system (e.g., with Pylontech batteries), this battery can likely be integrated. Always verify compatibility with your specific inverter model and its communication protocols (RS485, CAN, RS232).
