Learn about the Solar2High error code on Delta Electronics inverters, its meaning, causes, and solutions.
The Solar2High error typically indicates that the solar input voltage is too high. This can occur due to excessive sunlight or system configuration issues.
To troubleshoot, check the solar panel voltage and ensure it is within the inverter's specifications. Adjust the panel configuration if necessary.
The Solar2High fault is typically triggered when the inverter detects input voltages that exceed its maximum operational thresholds. This can occur due to a variety of factors, including excessive solar irradiance or malfunctioning components within the solar array. The inverter's internal logic continuously monitors the input voltage against pre-defined limits. If the voltage exceeds these limits, the inverter activates safety protocols to prevent potential damage, such as overheating or electrical arcing. This fault may also relate to grounding issues or improper string configurations that lead to voltage imbalances.
When the Delta Electronics inverter displays the Solar2High fault code, users may observe a flashing LED indicator or a warning alert on the monitoring app. Additionally, there may be a noticeable drop in energy production, indicating that the inverter has entered a protective state to prevent damage.
Always consult a licensed electrician or certified solar installer when performing maintenance or troubleshooting on solar systems to ensure compliance with safety standards and local electrical codes.
To avoid encountering the Solar2High fault in the future, ensure regular maintenance of the solar array, including cleaning the panels to maximize efficiency and monitoring the system for any signs of wear or damage. Periodically check the grounding system and verify that all connections remain secure and corrosion-free. Additionally, adhere to proper string configurations and consult the inverter's system manual to ensure compliance with voltage specifications.
