Solar Inverter Error Codes & Troubleshooting

solar inverter


When your solar inverter starts to play up it’ll display an error law that can help you troubleshoot the problem. In this companion we bandy solar inverter error canons for all the major solar brands & give troubleshooting to help you fix the problem.
Fronius Inverter Error Canons
A great thing about Fronius inverters is that they perform tone- an opinion which automatically informs the proprietor about the problem incontinently. Fronius inverter models have different fault and error canons. These canons are distributed as
Class 1 which is a evanescent problem and presumably caused by the public grid
Class 3 which are generally problems in feeding energy to the grid but only for a short period of time
Class 4 which formerly needs the intervention of an accredited solar installer or mastermind
Class 5 which don’t generally intrude with energy feeding but may beget some restrictions
Error Code 314
Error Code 314 on a Fronius inverter means that there’s a current detector estimation downtime or there’s an internal system error. Generally, this problem just fixes itself as the inverter repeats its incipiencyroutine. However, you should communicate us on(08)7078-7620 to probe the issue, If the problem persists.

Error Code 509
Still, it means that there’s no energy fed into the grid in the last 24 hours, If your Fronius inverter encounters Error Code or State Code 509. 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 communicate us to break thisproblem.However, we will check your inverter further, If it still doesn’t work.

Growatt Inverter Error Canons
Whenever a Growatt solar inverter gests faults, it’ll display the fault or error law. These canons indicate a particular problem or fault that the inverter is in. Listed below are some common error and fault canons that Growatt inverter druggies may face in the future and how it can be fixed

Error Code 102
When your Growatt solar inverter displays the Error Code 102, it means that the two CPU slice date is inconsistent. To fix this problem, turn off the DC switch and stay until the inverter is completely shut down. Turn the inverter on again and observe if it still displays the same error.
Error Code 111
An Error Code 111 generally happens with a Growatt TL3 inverter series. When this error shows up, it means that there’s an IGBT drive fault and that you should formerly communicate your solar inverter installer for a scan.

Error Code 117
An Error Code 117 on a Growatt solar inverter means that there’s a problem in the relay circuit. Try to renew the inverter and if the problem persists, you should formerly communicate your solar inverter installer.

Error Code 120
When a Growatt solar inverter displays the Error Code 120, it means that there’s a problem with the current detector. This Error Code is also known as an HCT Fault.

Fault Canons
Growatt solar inverters can witness two types of faults system faults and inverter faults.
HCT Fault
As stated over, an HCT Fault means that the inverter is having problems with its current detector. To repair this, simply renew the inverter and if it still is n’t fixed, communicate your solar inverter installer.

PV Insulation Low
PV Insulation Low is a system fault on a Growatt solar inverter. This means that the inverter’s PV sequestration impedance is too low or out of range.

Zeversolar Inverter Error Canons
Listed below are some common error and fault canons that Zeversolar inverter druggies may face in the future and how it can be fixed

Error Code 3
Error Code 3 is also known as a Relay- Check Fault. It means that the affair relay of the inverter has failed and might be in need of replacing. This error is displayed as‘Rly- Check Fault’in the Zeversolar inverter.
Error Code 34
Error Code 34 is also known as Vac Failure. When your Zeversolar inverter encounters this error law, it means that the grid voltage is out of the permitted range.

Error Code 35
Error Code 35 is also known as Utility Loss. It means that the mileage can not be detected due to the following reasons

There’s no mileage grid is available
The AC string is damaged
A fuse is broken during islet mode
Error Law 38
Error Code 38 is also known as Insulation Failure. In this error, the inverter’s PV array’s sequestration resistance ground is lower than the permitted value or the electrical sequestration has failed.
Error Code 48
Error Code 48 is an external fault that requires an examination from a solar technician. This isn’t listed in the stoner installation primer so it’s better to take it up with Zeversolar’s client service or contact Anew Solar so one of our technicians can look further into the problem.

Goodwe Inverter Error Canons
Whenever a Goodwe solar inverter is defective, it’ll display a communication indicating what kind of error or problem it’s having. Some exemplifications of these error canons are listed below and the possible results to them

Error Code 23
When a GoodWe solar inverter displays an error code 23 message, it means that the inverter is suffering from utility loss and there is a fault or a disconnection in the grid. Check whether the grid and its connection cables are in proper condition or that the cables are connected properly.

Fault Codes
Other GoodWe fault and error codes are as follows:

01 – SPI failure or an internal communication failure
02 – EEPROM R/W failure or memory chip failure
03 – Fac failure or the grid frequency is out of range
07, 25 – Relay check failure or a relay self-checking failure
13 – Overhigh DC injection
14 – Isolation failure
15 – Vac failure
16 – EFan fault
17 – PV over voltage
19 – Over temperature
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
Eversolar Inverter Error Codes
Like any other solar inverters, Eversolar also has its own fair share of inverter faults that are experienced by its users. Below are some of the most common inverter faults:

Isolation Fault
An Isolation Fault message on your Eversolar inverter could mean that there is wrong with the cables or wiring or it could mean that there is an internal fault with the inverter. If all the solar system cables are all properly connected, then you should already contact a solar expert because your inverter is not working.

Relay Fault
When an Eversolar inverter has a Relay Fault error, it will reboot itself until the problem is fixed. However, if it keeps displaying the same message after countless reboots, there is something wrong with the inverter and it might be best to contact a solar expert to look at it.
