In this detailed guide, we'll provide you with comprehensive troubleshooting steps to address common issues and get your solar inverter back online promptly.


Identifying and Resolving Common Issues

1. Power Interruptions


Your solar inverter may cease working due to power interruptions, such as grid outages or voltage fluctuations.


1. Grid Connection Check: Ensure that your solar system remains connected to the grid.

2. Circuit Breaker Inspection: Look for any tripped circuit breakers and reset them as necessary.

3. Voltage Monitoring: Utilise a multimeter to measure voltage levels and confirm if they fall within acceptable parameters.

2. Overheating


Overheating can trigger your solar inverter to shut down as a protective measure.


1. Ventilation Assessment: Ensure adequate ventilation around the inverter to prevent overheating.

2. Air Filter Maintenance: Regularly clean or replace air filters to prevent dust and debris buildup, which can obstruct airflow.

3. Shading Evaluation: Evaluate if the inverter is exposed to direct sunlight or situated in a shaded area, as excessive heat can impair performance.

3. Firmware Concerns


Outdated or corrupted firmware can contribute to inverter malfunctions.


1. Firmware Update: Visit the manufacturer's website to check for available firmware updates and follow the provided instructions for installation. At European Network Services we offer firmware updates on selected models contact us for more information.

2. Factory Reset: Perform a factory reset on the inverter to rectify any software glitches.

4. DC/AC Disconnect


A disconnect between the DC and AC sides of the inverter can hinder efficient energy conversion.


  1. Wiring Inspection: Thoroughly examine all wiring connections for signs of looseness or damage.

  2. Reconnection Procedure: If disconnected, securely reconnect the DC and AC terminals of the inverter.

5. Environmental Factors


Extreme weather conditions or environmental elements may impact inverter performance.


  1. Weatherproof Enclosure: Ensure that the inverter is housed in a weatherproof enclosure to shield it from rain, snow, or dust.

  2. Temperature Monitoring: Install temperature sensors to monitor the inverter's operational temperature and take necessary precautions during adverse weather conditions.


In conclusion, a malfunctioning solar inverter can significantly hinder the efficiency and productivity of your renewable energy system.
