Fronius Inverter Problems, Troubleshooting & Repairs

Fronius is a globally recognised solar inverter brand that was founded in Pettenbach, Austria in 1945. Fronius is manufactured in Germany and currently has 30 subsidiaries across 60 countries. It began investing in renewable energy, specifically solar energy, in 1992, but it wasn’t until 1995 that Fronius developed its first inverter, the “Sunrise.” When they introduced the Fronius IG inverter in 2001, they had already made a significant leap forwards in the field of inverters. Over its years of operation, Fronius has made it its goal to innovate and develop solar energy to be a primary source of sustainable and efficient energy.

Clean NRG not only offers these efficient and energy-saving inverters but also provides services, repairs and technical support for inverters both in and out of warranty. Our highly experienced solar technicians will ensure any Fronius inverter problems will be resolved. We supply Fronius customers with a variety of solar inverter including the Fronius Symo and Fronius Galvo.

Fronius Fault Codes & Errors:
Fronius solar inverters come with the advantage of conducting a self-diagnosis, which will automatically notify you of any problems. These errors are categorised into four fault classes:

• Class 1 is a temporary problem caused by the public grid
• Class 3 are typically encountered when there are issues feeding energy into the grid but are only temporary
• Class 4 requires the assistance of an accredited solar engineer or installer
• Class 5 doesn’t generally disrupt energy feeding but could cause some restrictions

Each inverter fault code has its own possible causes. Here are a few common Fronius fault codes with explanations and possible remedies:

Fault Code 567
If State Code or Error Code 567 appears on your Fronius Solar Inverter, it means that the solar inverter has activated grid voltage-dependent power reduction mode (GVDPR). This means the solar inverter is operating with reduced power output. If this code persists, contact us to resolve the issue.

Fault Code 509
Error Code 509 on a Fronius inverter indicates no energy has fed into the grid over the last 24 hours. There could be several reasons for this, one being that the solar panels are dirty.

Fault Code 314
If you encounter an Error Code 314 on your Fronius Inverter this indicates a current sensor calibration timeout or an internal system error. This problem can resolve itself once the solar inverter repeats its startup routine. If the problem persists, get in touch with us for Fronius customer support at (08) 9244 9200 and our solar repairs technicians will investigate.
