Possible Causes

Vehicle drawing more current than configured limit, Incorrect current setting in Enel X app, Short or partial short in output wiring or connector, Faulty current sensor on control board

How to Fix / Troubleshooting

Safety: Overcurrent can overheat wiring. Turn OFF the breaker if you smell burning or see discoloration.

  • Step 1 – Check current settings: Open the Enel X app and verify the maximum current setting matches the circuit rating (e.g., 32 A on a 40 A breaker). Correct any misconfiguration and save.
  • Step 2 – Inspect cable and connector: Look for melted plastic, burn marks, or soft spots along the cable. If present, discontinue use and replace the cable assembly.
  • Step 3 – Try a different vehicle: If possible, test with another EV to rule out a vehicle-side fault drawing excessive current.
  • Step 4 – Internal current sensor check (advanced): With power OFF and cover removed, locate the current transformer (CT) or shunt on the output lines. Inspect for discoloration, cracking, or loose wiring to the control board.
  • Step 5 – Reset and monitor: Restore power, clear the error via app or front panel, and start a charge while monitoring current draw in the app. If E05 recurs at normal current levels, the current sensor or control board is likely faulty.
