1. Introduction
Thank you for choosing the ECO-WORTHY Solar Charge Controller. This device is designed to manage the power flow from your solar panel to your battery, ensuring efficient charging and protecting your battery from overcharge and over-discharge. This manual provides essential information for the safe and effective use of your solar charge controller.
This controller is suitable for 12V and 24V lead-acid batteries (GEL, Sealed, Flooded) and lithium batteries (LiFePO4, Lithium-ion). It features an LCD display for easy monitoring and USB ports for charging small electronic devices.
2. Safety Information
- Ensure all connections are tight and correct before operation. Loose connections can cause excessive heat.
- Install the controller in a well-ventilated area, away from direct sunlight, high temperatures, and moisture.
- The controller generates heat during operation; ensure adequate airflow around the unit.
- Connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order.
- Do not connect any inverter directly to the load terminals of the controller. Connect the inverter directly to the battery.
- Use appropriate wire gauges for all connections to prevent overheating and voltage drop.
- This controller is for off-grid solar systems only. Do not connect it to an AC power source.
- Keep out of reach of children.

- Low Voltage Recovery Voltage: Voltage at which the load reconnects after low voltage disconnect.
- Low Voltage Cut-off Voltage: Voltage at which the load disconnects to protect the battery.
- Light Control ON/OFF: Enables or disables light-sensitive load control.
- Short Circuit Protection: Indicates short circuit status.
- PWM Charge Setting: Pulse Width Modulation charging settings.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Tighten any loose connections.
- Clean the Controller: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
- Inspect Wiring: Check for any signs of wear, fraying, or damage to the cables. Replace damaged cables immediately.
- Ventilation: Ensure the installation area remains well-ventilated to prevent overheating.
- Battery Health: Monitor your battery's health and ensure it is properly maintained according to its manufacturer's guidelines.
7. Troubleshooting
The controller's LCD display will show error codes if an issue occurs. Refer to the following table for common error codes and their solutions.
Figure 7.1: Error codes E01, E02, E03.
Figure 7.2: Error codes E04, E05, E06.
| Error Code | Description | Solution |
|---|---|---|
| E01 | Battery low voltage. The controller disconnects the load output when battery voltage is below LVD (Low Voltage Disconnect) to prevent over-discharge. | The controller will automatically turn on the load after the battery voltage returns to LVR (Low Voltage Reconnect). You can also click the button to force recovery. |
| E02 | Battery high voltage. The controller disconnects the load output if the battery voltage exceeds HVD (High Voltage Disconnect) for any reason. | The controller will automatically turn on the load after the battery voltage returns to HVR (High Voltage Reconnect). You can also click the button to force recovery. |
| E03 | Overcurrent load. If the load current exceeds the rated current, it will enter a short-circuit protection state if not returned to a safe value within 60 seconds. | Click the button to force recovery. Reduce the load or check for short circuits. |
| E04 | Load short circuit. If a short circuit protection occurs at the load end, the load will immediately turn off, and the controller will automatically restart the load after 10 seconds. Some models do not have this function. | Check the load for short circuits and correct them. The controller will attempt to restart the load. |
| E05 | High temperature anomaly. If the controller temperature exceeds 80°C, the controller will shut down. | Do not charge or discharge at this time. Wait for the temperature to drop below 70°C before resuming operation. Ensure adequate ventilation. |
| E06 | Solar panel overvoltage protection. If the solar panel voltage exceeds 50V, the controller will stop charging to protect the internal circuit. | Charging will resume when the voltage drops to 45V. Check your solar panel configuration to ensure it does not exceed the controller's maximum input voltage. |
