2. Safety Information
Always adhere to local electrical codes and safety regulations during installation and operation. Ensure proper grounding and ventilation. Do not attempt to open or modify the battery or inverter components, as this may void the warranty and pose safety risks. Keep the system away from flammable materials and sources of moisture.
The LiFePO4 batteries are designed with a robust metal case and a built-in 50A Battery Management System (BMS) to enhance safety. This BMS protects against overcharge, over-discharge, over-current, short-circuit, and manages cell voltage balance and high-temperature discharge cut-off.

5. Operating Instructions
The ECO-WORTHY system offers flexible operation with multiple charging and output modes.
5.1 Charging Methods
The system supports various charging methods:
- AC Mains Power: Charge your batteries directly from the grid. Maximum AC charge current is 40A, allowing for a full charge in approximately 2.5 hours.
- Solar Photovoltaic (PV) System: Prioritize charging from your solar panels. Maximum PV charge current is 80A, achieving a full charge in about 1.5 hours.

5.2 Hybrid Inverter Functions
The 5000W hybrid inverter acts as a 3-in-1 unit: inverter, controller, and charger. It can receive power from the grid for all-weather use and supports off-grid photovoltaic input. It automatically switches between utility and battery power based on three output modes:
- Solar Only / Solar Priority
- Mains Priority / Hybrid Charge

6. Maintenance
To ensure the longevity and optimal performance of your ECO-WORTHY Home Backup Power System, regular maintenance is recommended:
- Regular Inspection: Periodically check all cables and connections for any signs of wear, corrosion, or looseness. Ensure they are securely fastened.
- Cleanliness: Keep the inverter and battery surfaces clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure that the system's ventilation openings are not obstructed to prevent overheating.
- Battery Care: While LiFePO4 batteries are low-maintenance, avoid prolonged periods of full discharge. For long-term storage, it is recommended to store the batteries at approximately 50% State of Charge (SOC) in a cool, dry place.
- Software Updates: Keep the mobile application and inverter firmware updated to benefit from the latest features and performance improvements.
The LiFePO4 cells are designed for over 4000 cycles, offering a long operational life, typically exceeding 10 years with proper care.
7. Troubleshooting
If you encounter any issues with your ECO-WORTHY Home Backup Power System, consider the following basic troubleshooting steps:
- No Power Output: Check all cable connections, ensure the inverter is turned on, and verify battery charge level.
- Inverter Error Codes: Refer to the inverter's display for any error codes and consult the inverter's specific manual for their meaning and resolution.
- Charging Issues: Verify that the AC input or solar panels are providing power. Check charging cable connections. Ensure charging temperature is within the recommended range (32°F to 131°F).
- App Connectivity: Ensure your smartphone's Bluetooth or Wi-Fi is enabled and the app is updated. Restart the app or the inverter if connection issues persist.
