When a Project EV charging station displays a flashing red light, the exact meaning depends on the specific number of flashes in the sequence, which corresponds to a built-in diagnostic error code. For instance, a single red flash typically indicates that the charger has detected a dangerous grid overvoltage condition and shut down automatically, while four flashes signal an overcurrent protection trip, and eleven flashes point to a PE (Protective Earth) grounding fault. You can troubleshoot Project EV errors safely by cutting power at the fuse board. You can verify that your corrective action is successful when power-cycling the charger for one minute clears the flash sequence and returns the indicator light to a solid standby status.
