Inverter Error Codes
Inverter Error Codes and Their Meanings
The core of your solar system is the inverter, responsible for maintaining the stability of both incoming and outgoing power, ensuring a consistent flow without unusual fluctuations. At times, the inverter may detect minor or major issues and communicate them through error or status codes. Understanding these codes is crucial, as resolving the matter can be as straightforward as restarting the inverter. In this guide, we will explore some of the prevalent error and status codes your inverter may display, assisting you in troubleshooting and determining the necessary steps.
Inverter Brands and their Error Codes
102 – High Voltage
Problem: Western Power’s grid voltage is too high and the inverter is shutting down to protect itself.
Solution: Monitor the inverter over 2-3 days to see if the issue continues as this can just be an intermittent fault due to grid works or disturbances.
NOTE: If the fault does not go away we will need to contact western power and lodge a submission for over-voltage.
567 – High Voltage…. Inverter ramping down (smoothing)
Problem: Western Power’s grid voltage is rising and the inverter is ramping down.
Solution: It is an Australian standard that the inverter has this function. One way to reverse the voltage increase is by increasing the load in the house.
996 – Communication error
Problem: The inverter is no longer connected to the portal/internet/wifi.
Solution: Have you changed your network provider/wifi password/gone nbn. Click here for the step by step to reconnect
475 – Earth Isolation
Problem: Potential water ingress in isolator or panel/plug. If received very early in the morning it can also be triggered by low light.
Solution: Please lodge a service ticket through the form at the bottom of this page or call us on 0408 382 929.
301 – Internal error
Problem: Internal DC error.
Solution: Restart the inverter. Click here for step by step instructions on how to restart your inverter. Once the inverter has been restarted press the enter button on Fronius and leave the inverter for 5 minutes. If the green light doesn’t come on and the inverter is still displaying this error code then please lodge a service ticket through the form at the bottom of this page.
306 to 307 – Low PV/DC
Problem: Low DC Power coming from the panels.
Solution: *When did the code display? Did it go away? This code can display in the very early morning and very late evenings when the solar is switching off. If the code is displaying in the middle of the day (restart inverter) if still displaying please lodge a service ticket through the form at the bottom of this page.
509 – No power produced for 24 hours
Problem: Inverter is not producing power, usually caused by a blackout or surge/disturbance at the grid.
Solution: Restart the inverter. Click here for step by step instructions on how to restart your inverter.
SolarEdge will provide you with a number for any alert that you receive. These number range from 1-8
ALERTS
PROBLEM: 1 & 2 – Represent communication has been lost between the internet and the inverter
SOLUTION: Check your monitoring portal to see if it says online/disconnected. If this is the case then please Click here for instructions to reconnect.
PROBLEM: 3 TO 8 – This can represent several different options relating to the inverter.
SOLUTION: Please create a service ticket using the form at the bottom of this page. One of our team will then investigate and be back to you within 48 hours.
STATUS CODES
2, 3, 14, 15 – Grid Overvoltage
Problem: Western Power’s grid voltage is too high and the inverter is shutting down to protect itself.
Solution: Monitor the inverter over 2-3 days to see if the issue continues as this can just be an intermittent fault due to grid works or disturbances.
NOTE: If the fault does not go away we will need to contact western power and lodge a submission for over-voltage.
4, 5 – Grid Undervoltage
Problem: Western Power’s grid voltage is below the inverter allowable limit.
Solution: Generally, the inverter will be reconnected to the grid after the grid returns to normal. Monitor the inverter over 2-3 days to see if the issue continues as this can just be an intermittent fault due to grid works or disturbances. If the fault occurs repeatedly please create a service ticket using our website chat or using the form at the bottom of this page.
Disconnect/No connection – Communication error
Problem: The inverter is no longer connected to the portal/internet/wifi.
Solution: Have you changed your network provider/wifi password/gone nbn. Click here for the step by step to reconnect
