OpenEVSE Charging Issue - "NO GROUND" Error / Stops Charging

Hi all,

I am having an issue with my OpenEVSE setup and would appreciate some help.

My Setup:

Hardware: OpenEVSE v5.5 Board

Firmware: Latest stable release

Problem:

The unit fails to initiate charging and displays a "NO GROUND" error on the LCD screen, even though the main power connection is properly grounded.

Logs / LCD Message:

Error: NO GROUND

Has anyone encountered this issue before, or know how to bypass/fix this ground check feature?

Thanks in advance!

Is the OpenEVSE controller grounded? Both screw holes on the bottom need to connect to ground. On our kits this is done through the metal plate, standoffs and screws.
