Further troubleshooting tips based on equipment type:
• If using a Mobile Connector, try charging your vehicle with a different wall outlet.
◦
If charging speed is no longer reduced, the issue was likely with the original wall outlet. It is recommended that
you contact an electrician to inspect the building wiring connection to that outlet.
◦
If charging speed is still reduced, the issue may be with the Mobile Connector or the electrical grid.
• If using a Wall Connector, try charging your vehicle with different charging equipment like a Mobile Connector
powered by a separate wall outlet.
◦
If charging speed is no longer reduced, the issue was likely with the Wall Connector. Contact an electrician to
inspect the building wiring connection to the Wall Connector. They should make sure that all wires are
properly connected and torqued according to the installation guide for the Wall Connector.
As this alert may be present due to external charging equipment and power sources, it is recommended that you:
• Try charging with different wall outlets.
• Try charging with multiple, different types of charging equipment at different locations.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle's touchscreen display. See
Maps and Navigation on page 129
for more
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.
If this alert persists when attempting to charge at multiple locations and with different charging equipment, it is
recommended that you schedule service.

(PCS_a032)
Poor electric grid power quality detected
Try different charging station or location
Charging speed has been reduced or charging has been interrupted due to a condition that affects your vehicle’s
ability to charge with AC power. DC fast charging / Supercharging should still function as expected.
The onboard charger in your vehicle has detected power supply disturbances in the electrical power grid. These
disturbances interfere with your vehicle's charging process.
Typical causes of these power supply disturbances include:
• Issues with the building wiring and/or the wall outlet.
• Issues with the external charging equipment.
• Other large electric devices, such as washing machines or air conditioning units, that temporarily draw a lot of
power or otherwise disturb the electrical power grid.
• External conditions affecting the electrical power grid.
As this alert is usually specific to external charging equipment and power sources, and it does not typically indicate
an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:
• Try charging with different wall outlets.
• Try charging again (disconnect and reconnect to retry) when other large electric devices are not drawing power.
• Try charging with multiple, different types of charging equipment at different locations.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle's touchscreen display. See
Maps and Navigation on page 129

details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.
