Possible Causes
Generator undersized for load, Governor response too slow, Weak AVR, Loose neutral or ground connection
How to Fix / Troubleshooting
Safety first: Have a qualified electrician evaluate the load and wiring. Do not exceed the generator's rated capacity.
- Assess load: Calculate total running and starting watts of connected appliances. Move large motor loads off the standby system if necessary.
- Check wiring connections: Tighten neutral and ground connections at the generator, ATS, and main panel.
- Verify governor and AVR: Ensure the governor linkage is free and the AVR is functioning. Replace weak components as needed.
- Stagger load startup: Configure high‑demand appliances to start at different times to reduce simultaneous inrush.
