EV Charger Error

Insufficient Grid Power

Updated March 2026

Share

This is general guidance based on the ChargeX MREC standard. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure.

Warning

The electrical supply to the charger site is limited. The charger cannot deliver its full rated power because the grid connection does not support it right now. This can happen during peak demand hours.

What to do

  1. Charging may still work but at reduced speed
  2. Try charging at off-peak hours when grid demand is lower
  3. Move to a different charging location if speed is too low
  4. This is a site infrastructure issue, not your vehicle's fault

Who's responsible?

  • The charging network operator needs to fix this
