Growatt Inverter Fault & Error Codes

Whenever a Growatt solar inverter experiences faults, it will display the fault or error code. These codes indicate a particular problem or fault that the inverter is in. Listed below are some common error and fault codes that Growatt inverter users 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 sampling date is inconsistent. To fix this problem, turn off the DC switch and wait until the inverter is totally shut down. Turn the inverter on again and observe if it still displays the same error.

Error Code 111

An Error Code 111 usually happens with a Growatt TL3 inverter series. When this error shows up, it means that there is an IGBT drive fault and that you should already contact your solar inverter installer for a checkup.

Error Code 117

An Error Code 117 on a Growatt solar inverter means that there is a problem in the relay circuit. Try to restart the inverter and if the problem persists, you should already contact your solar inverter installer.

Error Code 120

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

Fault Codes

Growatt solar inverters can experience two types of faults: system faults and inverter faults.

HCT Fault

As stated above, an HCT Fault means that the inverter is having problems with its current sensor. To repair this, simply restart the inverter and if it still isn’t fixed, contact your solar inverter installer.

PV Isolation Low

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

Growatt Inverter Troubleshooting & Repairs

There are some Growatt solar inverter problems that are easy to troubleshoot and repair in just a few simple steps. Here are some common inverter problems with solutions that you can try by yourself:

Not Working / No Display

A Growatt inverter that displays nothing is a big problem since you do not know what is really wrong with your inverter. There are two reasons why this can happen:

  • There is no DC power is getting to the inverter
  • The inverter is broken

However, before you panic, try these following steps to fix it:

  1. Check if your inverter is really switched on and the DC isolator is also turned on.
  2. Check if all the light indicators are green.
  3. You can also try rebooting the whole system.

Beeping Noise

When a Growatt solar inverter makes a clicking or a beeping noise, it is only normal especially when it is in the process of turning on and turning off. There will also be noise when the inverter is working really hard in peak times. If there is a fault, the error code will be displayed in the LCD screen.

Red Light

A red light in a Growatt solar inverter indicates that there is a fault somewhere. Try resetting the whole system and if the red light still stays on after it, it is time for a solar technician to look at it.

If your solar inverter problems persist even after doing these simple fixes or if you are experiencing other issues that are not mentioned above, reach out to us and we will send an accredited solar technician or electrician to your place.
