Zappi Charger Problems
If you’ve recently installed a Zappi charger for electric vehicles (EVs) and encountered the frustrating ‘Check CT grid’ error message, you’re not alone. Many users have faced this issue, and in this article, we’ll delve into the problem and provide possible solutions to get your Zappi charger up and running smoothly.
The Mysterious ‘Check CT Grid’ Error
One Zappi charger user shared their experience of encountering the ‘Check CT grid’ message when trying to charge their EV. This error can be perplexing and may leave you scratching your head for a solution. Fortunately, the community came together to offer some valuable insights.
CT Clamp Connection
Some users questioned whether the ‘Check CT grid’ error had anything to do with the use of a CT clamp. A CT clamp, short for current transformer clamp, is often used to measure the electric current passing through a cable or wire. In this case, it was noted that the user had not installed a CT clamp due to the charger being well within the maximum demand (100A fuse).
Manual Investigation
One user suggested referring to the Zappi charger manual for guidance. Manuals often contain essential information about troubleshooting and configuring settings. In this situation, it was speculated that there might be a setting or jumper that needs adjustment if the CT clamp is not connected.
Disabling CT Clamp
The key to resolving the ‘Check CT grid’ issue appeared to lie in disabling the CT clamp settings. Users shared that the Zappi charger comes with a default setting that assumes the CT clamp is connected. To disable this setting and rectify the problem, you need to navigate through the charger’s menus.
Here are the steps to disable the CT clamp settings:
- Enter the charger’s menu.
- Access the advanced settings. You may need a specific code (usually 0000) to enter this section.
- Locate the CT configuration (CT config) in the menu.
- You will likely see CT1, CT2, and CT3 settings. Use the arrow keys to turn these settings to ‘off.’ It’s CT1 that is typically set as ‘on’ and configured for grid CT. By turning it off, the charger won’t look for the grid CT, resolving the ‘Check CT grid’ issue.

One user expressed gratitude for the community’s assistance in resolving the problem. They acknowledged that seeking help from Zappi’s customer support might result in a lengthy process, with no guarantee of a quick solution. In this case, the advice provided by fellow users proved invaluable and saved both time and potential frustration.
Conclusion
If you encounter the ‘Check CT grid’ error while using your Zappi charger, remember that you’re not alone, and there are solutions to this problem. By following the steps outlined above to disable the CT clamp settings, you can likely resolve the issue and get back to charging your EV hassle-free.
