Grizzl-E Supply Voltage Fluctuation / Line Sag

Grizzl‑E LEDs flicker or dim when large household loads turn on or off

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shared service with heavy loads (HVAC, range), Undersized service entrance, Loose service or panel connections, Long feeder run with voltage drop

Safety: Service entrance issues must be handled by a licensed electrician or utility.

Observe pattern: Note which household loads cause flicker and whether charging is interrupted.
Measure voltage: With a meter, monitor line voltage at the Grizzl‑E while large loads cycle. Significant dips indicate supply issues.
Panel inspection: Have an electrician check for loose lugs or overloaded buses in the main panel.
Mitigation: Consider load management, upgrading service, or relocating the charger to a less loaded panel if voltage sag is severe.
