Possible Causes

Incorrect mains voltage/frequency thresholds, Unstable utility supply, Faulty mains sensing circuit, Loose neutral connection

How to Fix / Troubleshooting

Safety first: Utility work should be done by qualified electricians. Lock out ATS before inspection.

  • Step 1 – Monitor mains: Use a multimeter or power quality meter to verify actual mains voltage and frequency at the ATS.
  • Step 2 – Check neutral and ground: Ensure tight, corrosion‑free connections at the ATS and service entrance. Loose neutrals can cause voltage fluctuations.
  • Step 3 – Review controller settings: In the Kipor controller, verify that start/stop thresholds for mains failure are set per manufacturer recommendations, not overly sensitive.
