Power Generation Issues ⚡

Efficient power generation is the primary goal of any solar panel system. Errors in this category can significantly impact your energy yields.

1. Low Sunlight Error (E01)

• Description: The system detects insufficient sunlight.
• Solution: Ensure panels are not shaded or obstructed by debris. Consider adjusting panel angles or relocating to a sunnier spot.

2. Overvoltage Error (E02)

• Description: The DC input voltage exceeds the system’s maximum limit.
• Solution: Check for wiring issues or excessive sunlight concentration. Install voltage limiters if persistent.

3. Undervoltage Error (E03)

• Description: The DC input voltage falls below the system's operational threshold.
• Solution: Verify panel connections and conditions. Check for faulty panels or wiring issues.

4. Temperature Alarm (E04)

• Description: The system detects excessive temperatures on the panels.
• Solution: Ensure proper ventilation around panels. Consider cooling methods or shading mechanisms.

5. No Output Error (E05)

• Description: System fails to generate any power.
• Solution: Check connections, inverter functionality, and panel integrity.

Inverter Error Codes 🔌

Inverters play a crucial role by converting DC from your panels into AC for home use. Understanding these errors helps maintain system health.

Battery Storage Problems ⚡🔋

Battery storage enhances the usability of solar power, but issues can arise that may affect performance.

1. Overcharge Error (B01)

• Description: Battery voltage exceeds maximum charging threshold.
• Solution: Inspect battery management settings. Utilize charge controllers or protection devices.

2. Undercharge Error (B02)

• Description: Battery voltage below minimum working threshold.
• Solution: Review charging circuit and schedule. Replace degraded batteries.

3. High Battery Temperature (B03)

• Description: Temperature exceeds safe operating limits.
• Solution: Check for adequate ventilation and cooling. Replace if persistent overheating occurs.

4. Battery Connection Fault (B04)

• Description: Loose or corroded connections impacting performance.
• Solution: Secure and clean all battery terminal connections.

5. Capacity Decline (B05)

• Description: Noticeable drop in battery storage capacity.
• Solution: Test individual batteries and replace failing ones. Consider upgrading battery banks.

Monitoring System Faults 📈

Monitoring systems offer insights into the performance and health of your solar setup. Errors in this domain can hinder information accuracy.

1. Data Communication Failure (M01)

• Description: No communication between monitoring system and solar arrays.
• Solution: Verify network connections, address IP conflicts, and restart the devices.

2. System Calibration Error (M02)

• Description: Misalignment in reported and actual performance metrics.
• Solution: Recalibrate the monitoring system by referencing manufacturer's guidelines.

3. Inaccurate Energy Metrics (M03)

• Description: Fault in energy tracking or reporting results.
• Solution: Reset monitoring software, update firmware, and check sensor placements.

4. Power Flow Errors (M04)

• Description: Unexpected deviations in recorded energy flow.
• Solution: Inspect for system updates or errors in panel alignment.

5. Unauthorized Access Alerts (M05)

• Description: Unauthorized attempts to access system data.
• Solution: Enhance network security with strong passwords and firewalls. Regularly update security measures.
