Fronius is a globally-established brand originating from Pettenbach, Austria since 1945 which already has 30 subsidiaries in over 60 countries. In 1992, it started to engage in renewable energy particularly solar energy but it was only in 1995 when Fronius developed their first inverter, “Sunrise”. By 2001, they already made a great leap when it comes to inverters when they introduced the Fronius IG. Throughout the years, Fronius made it their mission to research and develop solar energy as a means of a sustainable and efficient energy source.
For inverter products, Fronius customers can choose from different options such as:
- Fronius Galvo
- Fronius Galvo UL
- Fronius Primo
- Fronius Primo UL
- Fronius Symo Hybrid
- Fronius Symo
- Fronius Symo UL
- Fronius Eco
While these products are very efficient in energy saving, it will most likely encounter problems along the way. With the help of our accredited solar electrician, these problems will be solved.
Fronius Inverter Fault & Error Codes
A great thing about Fronius inverters is that they perform self-diagnosis which automatically informs the owner about the problem immediately. Fronius inverter models have different fault and error codes. These codes are categorized as:
- Class 1 which is a momentary problem and probably caused by the public grid
- Class 3 which are usually problems in feeding energy to the grid but only for a short period of time
- Class 4 which already needs the intervention of an accredited solar installer or engineer
- Class 5 which do not generally interfere with energy feeding but may cause some restrictions
Error Code 314
Error Code 314 on a Fronius inverter means that there is a current sensor calibration timeout or there is an internal system error. Usually, this problem just fixes itself as the inverter repeats its startup routine. If the problem persists, you should contact us on (08) 7078-7620 to investigate the issue.
Error Code 509
If your Fronius inverter encounters Error Code or State Code 509, it means that there is no energy fed into the grid in the last 24 hours. There could be a lot of reasons for this and one of them is that the solar panels are covered in dirt. One of Anew Solar’s service is solar panel cleaning so you might want to contact us to solve this problem. If it still does not work, we will inspect your inverter further.

What’s The Procedure to Make a Warranty Claim?
Before claiming a warranty exchange or repair on your Fronius inverter, you should first contact your solar installer. If the warranty is approved, you need to present the following to be able to continue:
- Proof of purchase that the inverter model was installed in less than five years
- The serial number of the Fronius product
- Installation report
- Proof of payment of warranty extension fee, if necessary
The inverter parts that needed to be exchanged should also be returned in quality packaging. From then, we will file your warranty claim to Fronius and wait until the replacement comes in so we could begin the installation.
What Can I Do If I’m Out of Warranty?
If your Fronius inverter is out of warranty and something is needed to be replaced, there is still a chance that some parts can be repaired. Otherwise, it might be better to replace the old inverter with a new one for the better. If there are too many parts that needed replacing, it might cost you less when you buy a new inverter.

Fronius Inverter Troubleshooting & Repairs
There are common problems that Fronius solar inverter users have encountered. Below are some examples and how you can fix it:
Low PV Voltage
A Fronius inverter suffering from State Code or Error Code 307 probably has a low PV voltage. This error code usually appears in the morning or in the evening due to low solar exposure. It will correct itself immediately as soon as there is sufficient solar radiance.
Inverter is Offline
When your inverter displays offline, the problem might not lie on the inverter itself but on the network or router that it is connected to. Try resetting the router and see if the problem is resolved.
One of the cons of a Fronius inverter is that it tends to become noisy especially when it is working at its peak or in the morning or afternoon when the inverter is turning on or shutting down although it is not a big problem. If there is one, it will likely show the fault code and the fault light will be displayed. If the fault light is still during normal usage, you should try resetting the inverter.
However, if these problems persist even after you have done a troubleshoot, feel free to contact us at Anew Solar to help you resolve your inverter issues.
