Fronius Inverter Error Codes

Fronius inverters boast self-diagnostic capabilities, promptly notifying owners about potential issues. Different Fronius inverter models feature distinct fault and error codes, which are classified as:

• Class 1: Typically, transient issues, often attributable to fluctuations in the public grid.
• Class 3: Temporary disruptions in energy feed to the grid, usually of short duration.
• Class 4: Requires intervention from an accredited solar installer to resolve.
• Class 5: Generally, don’t impede energy feed but may impose certain restrictions.

Understanding these error codes enables you to address issues efficiently and maintain optimal solar energy performance.

Error Code 314

Error Code 314 indicates a current sensor calibration timeout or internal system error on your Fronius inverter. Typically, this resolves itself as the inverter repeats its startup routine. If the issue persists, contact us at 1300 054 488 for further investigation.

Error Code 509

Encountering Error Code 509 suggests no energy has been fed into the grid in the last 24 hours. Potential causes include dirt-covered solar panels. Call us on 1300 054 488 to book in our panel cleaning service to address this issue. If the problem persists, we’ll conduct a thorough inspection of your inverter.

Growatt Inverter Error Codes: Common Issues and Solutions

Error Code 102

Error Code 102 signifies inconsistent CPU sampling data in your Growatt inverter. To resolve, turn off the DC switch, allow the inverter to shut down completely, then restart and monitor for recurrence.

Error Code 111

Error Code 111, often occurring in Growatt TL3 series inverters, indicates an IGBT drive fault. Contact us on 1300 054 488 for prompt assessment.

Error Code 117

Error Code 117 points to a relay circuit problem in your Growatt solar inverter. Attempt a restart; if the issue persists, contact us on 1300 054 488 for assistance.

Error Code 120 (HCT Fault): Error Code 120 suggests a current sensor issue. Also known as an HCT Fault, try restarting the inverter; if the issue persists, seek assistance from us on 1300 054 488.

Zeversolar Inverter Error Codes

Error Code 3 (Relay-Check Fault): Error Code 3 indicates a failed output relay in your Zeversolar inverter. Consider replacing the relay to resolve this issue.

Error Code 34 (Vac Failure): Error Code 34 signals grid voltage outside permitted range. Ensure your grid connections are intact and within specifications.

Error Code 35 (Utility Loss): Error Code 35 suggests issues with utility detection. Check for grid availability, cable integrity, and fuse condition during island mode.

Error Code 38 (Isolation Failure): Error Code 38 indicates lower-than-permitted insulation resistance or electrical insulation failure in the PV array.

Error Code 48 (External Fault): Error Code 48 requires an inspection by one of our solar technicians, contact us on 1300 054 488

Goodwe Inverter Error Codes: Common Issues and Solutions

When your Goodwe solar inverter experiences faults, it communicates them through error codes, indicating the nature of the problem. Explore the following error codes and their potential solutions:
• Error Code 23: Indicates electricity loss, signalling a fault or disconnection in the grid. Verify the grid and connection cables for proper condition and secure connections.
Other common Goodwe Fault Codes Include:

• 01 – SPI failure or internal communication failure
• 02 – EEPROM R/W failure or memory chip failure
• 03 – Fac failure or grid frequency out of range
• 07, 25 – Relay check failure or relay self-checking failure
• 13 – Overhigh DC injection
• 14 – Isolation failure
• 15 – Vac failure
• 16 – EFan fault
• 17 – PV overvoltage
• 19 – Overtemperature
• 20 – IFan fault
• 21 – DC Bus High
• 22 – Ground I Failure
• 30 – Ref 1.5V failure
• 31, 24 – AC HCT failure
• 32, 26 – GFCI failure
• Others – Device failure

Understanding these codes helps you diagnose and resolve issues effectively for continued solar energy performance; if you require assistance with any of these issues please contact us on 1300 054 488

Eversolar Inverter Error Codes

Eversolar inverters encounter their own set of faults, each with its unique implications. Some common inverter faults include:

Isolation Fault: Indicates issues with cables, wiring, or internal faults within the inverter. Ensure all solar system cables are correctly connected and consider contacting a solar expert if the problem persists.

Relay Fault: The inverter may reboot itself upon encountering a Relay Fault. If the issue persists after multiple reboots, you can call us on 1300 054 488 to diagnose and rectify the problem.

SunGrow Inverter Error Codes: Understanding, Troubleshooting, and Solutions

When your SunGrow solar inverter encounters issues, it communicates them through error codes. Below is a breakdown of common error codes, their meanings, and steps for resolution:

002: Grid Voltage Exceeds Allowable Upper Limit

• Check grid voltage; if beyond permissible range, consult your electricity company.
• If within range, contact us on 1300 054 488 for assistance.

003: Grid Transient Voltage Exceeds Permissible Range

• Usually a short-term fault due to grid conditions; the inverter should rectify itself.
• If fault persists, contact us on 1300 054 488 for assistance.

004: Grid Voltage Below Inverter’s Allowable Lower Limit

• Check grid voltage; if exceeding protection parameters, consult your electricity provider.
• If within range and code persists, contact us on 1300 054 488 for assistance.

005: Grid Voltage Too Low

• Often a short-term fault due to grid conditions; inverter typically self-recovers.
• If issue persists, contact us on 1300 054 488 for assistance.

006: AC Output Current Exceeds Allowable Upper Limit

• Inverter resumes if output current falls below protection value.
• If fault persists, contact us on 1300 054 488 for assistance.

007: Transient AC Overcurrent

• Inverter self-recovers after several seconds; if issue continues, contact us on 1300 054 488 for assistance.

008: Grid Frequency Exceeds Allowable Upper Limit

• Check grid frequency; consult utility grid if beyond permissible range.
• If within range, contact us on 1300 054 488 for assistance.

009: Grid Under-Frequency

• Grid frequency below protective value; consult utility grid if necessary.
• contact us on 1300 054 488 for assistance if issue persists.
