Learn why your EG4 18kPV inverter is derating output due to high ambient temperatures and how to fix it.
Derating refers to the reduction in output power of an inverter due to high temperatures. This is a protective measure to prevent overheating and damage.
Ensure proper ventilation around the inverter and consider installing it in a shaded area to minimize temperature rise during hot weather.
The EG4 18kPV inverter is designed to operate within specific temperature ranges. When ambient temperatures exceed these limits, the inverter enters a derating mode to protect itself from overheating. This is a safety feature that prevents damage to internal components. The inverter uses temperature sensors to monitor its operating environment. If the temperature exceeds the rated threshold, the inverter reduces its output power to maintain safe operating conditions, thereby ensuring longevity and reliability. This derating is a direct response to thermal management protocols built into the inverter's firmware.
Users may notice a significant drop in power production as indicated by monitoring apps or physical LED patterns on the inverter. The inverter may display a warning light indicating reduced output, or the monitoring system may show a derating status. Additionally, users might observe that the output voltage from the inverter is lower than expected, particularly during peak sunlight hours.
Always consult a licensed electrician or certified solar installer when performing maintenance or troubleshooting on your solar inverter to ensure safety and compliance with local regulations.
To avoid future derating issues, ensure the inverter is installed in a well-ventilated area away from direct sunlight. Regularly clean the inverter and surrounding area to prevent dust accumulation. Periodically check ambient temperature and consider installing additional shade structures if necessary. Ensure that the inverter system complies with all manufacturer recommendations for placement and orientation.
