Possible Causes
Generator undersized for starting currents, Multiple large loads starting simultaneously, Weak engine performance, Incorrect ATS load shedding configuration
How to Fix / Troubleshooting
Safety first: Open the generator breaker to remove load before troubleshooting. Do not repeatedly restart under overload conditions.
- Review connected loads: List all major appliances on the generator circuit and their starting (LRA) and running currents.
- Stagger start times: Configure HVAC and pump controls to avoid simultaneous starting, or install soft‑start kits where appropriate.
- Check ATS load shedding: If your Genergy system supports load shedding, verify that non‑critical loads are assigned to shed during generator operation.
- Engine tune‑up: Perform maintenance (spark plugs, filters, valve adjustment if specified) to ensure the engine can deliver rated power.
