Learn how to safely perform a hard reset on your Fronius Galvo inverter with this guide.
To perform a hard reset, turn off the inverter, disconnect it from the power source, and wait for a few minutes before reconnecting it.
A hard reset can resolve minor software glitches, communication errors, and restore normal operation of the inverter.
Fronius Galvo inverters are designed to monitor various parameters, including insulation resistance (RISO), ground faults, and grid frequency. A fault may trigger if the RISO measurement indicates compromised insulation, leading to potential safety hazards. Ground fault detection is crucial for identifying unintended current paths, often caused by moisture intrusion or damaged wiring. Additionally, the inverter monitors grid frequency; deviations outside the acceptable range can prompt a shutdown to protect both the inverter and the connected array. Communication issues with the monitoring system can also cause misleading alerts, further complicating troubleshooting.
The Fronius Galvo inverter may exhibit abnormal LED patterns, such as continuous red or blinking yellow lights. Users may also receive alerts via the monitoring app indicating production drops or system faults. A sudden lack of energy production or erratic performance can also be observed, along with error codes that may not be specified.
Always consult a licensed electrician or certified solar installer before performing any maintenance or troubleshooting to ensure safety and compliance with local regulations.
To avoid future issues, ensure regular maintenance checks of the inverter and array components, including cleaning and inspecting for moisture or wear. Confirm that ventilation around the inverter is adequate and that the system complies with NEC regulations. Regularly verify insulation resistance and perform visual inspections of wiring and connections.
