A-iPower Intermittent Power / Flicker

Generator runs but some circuits in the building experience flickering lights or unstable power.

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

Loose neutral or phase conductor, Failing AVR, Unbalanced load across phases (for multi-phase units), Poor connections in ATS

Safety first: Work with a qualified electrician when dealing with building wiring and ATS connections.

Inspect generator connections: Tighten all phase and neutral lugs at the generator output and in the junction box.
Check ATS terminations: Ensure all connections in the ATS are tight and free of discoloration.
Measure voltage stability: With a meter, monitor voltage under load. Large swings suggest AVR or alternator issues.
Balance loads: For multi-phase systems, redistribute loads to balance current draw across phases.
