Growatt Inverter Problems

1 . Unexpected Error Messages

Unexpected error messages are usually a result of internal glitches or failures within the inverter.

These could be due to a variety of reasons, such as improper installation, software bugs, or hardware malfunctions. The error message displayed on the inverter’s screen is often a clue to the root of the problem.


To resolve these error messages, the first step is to record the specific message that appears.

You can then refer to the Growatt Inverter’s user manual or consult with a professional service provider to decipher the message and identify the appropriate solution.

If it’s a software issue, a system reset or update may be required.

For hardware issues, parts replacement may be necessary. Remember, it’s essential to regularly maintain your Growatt Inverter to prevent such issues from arising in the first place.

2 . System Performance Issues

System performance issues with Growatt inverters can arise due to several factors.

For instance, environmental conditions such as high temperatures or shading can affect the efficiency of the solar panels, consequently impacting the inverter’s output.

Improper configuration of the inverter or technical malfunctions within the system could also be at fault.

If you notice a significant drop in power production or inconsistent energy readings, it’s likely you’re dealing with a performance issue.


Addressing system performance issues begins with identifying the root cause.

Check environmental factors – ensure the solar panels are free from shade and debris, and are operating in suitable conditions.

Investigate the system’s configuration settings and make sure they’re in line with the manufacturer’s recommendations.

If these steps don’t improve performance, contact a professional service provider.

A skilled technician can carry out diagnostic checks to uncover any technical issues and implement the necessary repairs or replacements.

3 . Software Upgrade Failures

Software upgrade failures in Growatt inverters typically occur due to inconsistent or inadequate internet connections, power disruptions during the upgrade process, or corrupted update files.

An unsuccessful upgrade can lead to system malfunctions, error messages, or even complete system shutdown.

It’s important to ensure a secure and stable environment when performing a software update to prevent such issues.


The solution to software upgrade failures lies primarily in addressing their root causes.

First, ensure a stable and reliable internet connection before initiating the upgrade.

If power disruptions are a concern, use a uninterrupted power supply (UPS) during the upgrade process. For corrupted update files, try downloading the update again before installation.

4 . Temperature-Related Malfunctions

Temperature-related malfunctions in Growatt inverters occur when the device’s internal temperature exceeds its optimal running temperature.

This can be due to ambient temperatures being too high, inadequate ventilation around the device, or even a failure of the inverter’s internal cooling system.

Such overheating can lead to various system glitches, decreased performance, and, in extreme cases, a total system shutdown.


To address temperature-related malfunctions, start by checking the environment in which the inverter is installed.

The area should be well-ventilated and away from direct sunlight or other heat sources.

Also, ensure the inverter’s internal cooling system is functioning properly, replacing any faulty fans or components if necessary.

If the device continues to overheat despite these steps, it’s advisable to contact a professional technician. They can inspect the inverter, identify any underlying issues, and implement the necessary fixes.

5 . Difficulty in Reading Display Screen

Difficulty in reading the display screen of Growatt inverters can be caused by various factors.

These include physical damages to the screen, backlight malfunctions, low contrast settings, or even outdated firmware.

These issues can make it challenging to interpret the information displayed on the screen, hampering efficient monitoring and control of the solar power system.


The first step in resolving display reading difficulties is identifying the root cause.

If there’s physical damage, the screen may need to be replaced. For backlight issues or low contrast settings, adjusting the brightness or contrast through the inverter’s settings can help

. If outdated firmware is the cause, an update to the latest version may resolve the issue. If these steps don’t work, it’s recommended to seek professional help to restore the readability of the display screen.


In conclusion, while Growatt inverters are robust and reliable devices designed to convert solar energy into usable power, they may face various challenges such as error codes, system performance issues, software upgrade failures, temperature-related malfunctions, and display reading difficulties.

It’s important to understand these potential problems, their causes, and how to address them effectively.

Regular maintenance and adherence to the manufacturer’s recommendations can prevent many of these issues, ensuring optimal system performance.


What should I do if my Growatt inverter stops working?

Check the system for any visible signs of damage or error codes. If the problem persists, contact a professional technician for assistance.

How often should I perform maintenance on my Growatt inverter?

Regular inspection and maintenance every 6-12 months is advised to keep your inverter functioning optimally.

Can I perform a software upgrade on my Growatt inverter by myself?

Yes, you can. However, make sure you have a stable internet connection, and consider using an uninterrupted power supply (UPS) during the upgrade process.

What are the common causes of display reading difficulties on Growatt inverters?

Typical causes include physical damage, backlight malfunctions, low contrast settings, or outdated firmware.
