How to Reset Growatt Inverter

1 . Check Power Supply

Before you initiate the reset process, it’s important to first check the power supply to your Growatt Inverter. A power supply issue can often be the root cause of an inverter malfunction.

Firstly, verify that your inverter is connected to the power source correctly.

Secondly, check if there is a power outage in your area which might be affecting the inverter’s operation.

Lastly, ensure that the circuit breakers connected to the inverter are in the ‘ON’ position.

This preliminary check can save you time and effort by resolving simple power supply issues that might seem like a malfunctioning inverter.

2 . Inspect Wiring Connections

Inspecting the wiring connections is another pivotal step in troubleshooting your Growatt Inverter.

Misconnections, loose wires, or damaged cables can prevent your inverter from operating correctly.

Firstly, ensure that all wires are securely connected to their respective terminals.

Poor connectivity can result in an inconsistent power supply, causing your inverter to function improperly. Next, visually inspect all the wires for any signs of damage or wear.

Worn-out or damaged wires can disrupt the power flow, causing your inverter to malfunction. Lastly, make sure that there is no corrosion at the cable connections.

Over time, corrosion can build up at the connections, impairing the electrical flow and leading to inverter issues. A thorough inspection and rectification of these wiring issues can help restore the optimal functioning of your inverter.

3 . Isolate and Restart

The Isolate and Restart method is a simple yet effective step in resetting your Growatt Inverter.

Essentially, this method involves cutting off power to the inverter and then restarting it.

Firstly, you’ll need to isolate your inverter from the power source. To do this, turn off the DC isolators of the solar panels and the AC isolator of the inverter.

These switches are typically located around the unit. Wait for about 5 minutes. This downtime allows the inverter to fully shut down and clear any existing system errors.

After the waiting period, you can now restart the inverter.

Turn on the DC isolators of the solar panels first, and then the AC isolator of the inverter. Check the inverter’s display to verify it is functioning properly.

This isolate and restart method can often resolve minor glitches and restore your Growatt Inverter back to its normal operation.

4 . Reset Button

The reset button is a direct and effective way to reset your Growatt Inverter. It’s generally located on the front panel of the inverter.

Before you proceed, ensure that you have isolated your inverter from the power source.

Press and hold the reset button for about 5 seconds or until you see a reset signal or hear a beep indicating the reset process has been initiated.

After resetting, wait for a few minutes to allow the inverter’s systems to reboot.

Then, reconnect the power source and check the inverter’s display for any error messages.

If the display shows the normal operation status, your inverter has been successfully reset.

This reset button method is a quick and straightforward way to resolve minor technical issues with your Growatt Inverter.

5 . Check Error Codes

Checking the error codes displayed on your Growatt Inverter can provide critical insights into the issues plaguing your system.

Growatt Inverters are equipped with a diagnostic system that displays error codes on the inverter’s screen whenever a fault or issue is detected.

These error codes correspond to specific faults in the system, ranging from issues with the grid connection to problems within the inverter itself.

Consult the Growatt Inverter user manual to understand what each error code signifies.

Once you’ve identified the problem through the error code, you can take specific corrective measures to rectify the issue.

Remember, some error codes may indicate serious issues that require professional assistance.

Do not attempt to fix such issues on your own; instead, contact a certified solar technician or Growatt customer care.

6 . Software Updates

Keeping your inverter’s software updated is a crucial step in ensuring its optimal performance.

Growatt frequently releases software updates which include bug fixes and improvements that can rectify common inverter issues.

Firstly, check the Growatt website or contact their customer service to learn about any new software updates available for your inverter model.

Secondly, if an update is available, follow the manufacturer’s instructions to download and install the update.

Lastly, restart your inverter after installing the update to ensure the new software settings take effect.

7 . Professional Assistance

Should the prior steps fail to rectify the issue with your Growatt Inverter, it’s time to seek professional assistance.

Dealing with electrical appliances can be dangerous if not handled correctly, and inverter issues can sometimes be complex requiring technical expertise.

Do not attempt to open or repair the inverter yourself.

Instead, contact a licensed professional or Growatt’s customer service for support.

They have the knowledge and equipment to diagnose and rectify the problem safely and effectively.

Providing them with the details and results of your troubleshooting steps can help them address the issue more efficiently.
