The "Check Grid CT / Installation Limit / Grid CT Lost" error is one of the most commonly reported issues in myenergi systems. Fortunately, it often does not require installer or myenergi involvement, as most cases can be resolved with a simple self-check and adjustment by the user. However, if the grid CT is missing or has not been installed, you will need to contact your installer to complete the setup.

Impact of harvi Connectivity on Grid CT Performance
If you are using harvi and it disconnects due to distance or interference, this will temporarily stop the CT readings on the myenergi devices and provide the user an error. The system will automatically resume once connectivity is restored.
