Standby Generators: Essential Maintenance and Troubleshooting

Standby generators provide automatic backup power during outages, making them a crucial component for homes and businesses. These stationary units are connected directly to your electrical system and are typically more complex than portable generators.

Maintenance:

  1. Weekly Checks: Standby generators should be tested weekly. Run the generator for a short period to ensure it starts up correctly and that the system is functioning as expected. This also helps to keep the engine lubricated and the battery charged.
  2. Battery Maintenance: Check the battery’s charge and cleanliness regularly. A weak or dead battery is a common issue with standby generators. Clean any corrosion from the terminals and ensure the connections are secure.
  3. Coolant Levels: Regularly check and maintain proper coolant levels to prevent overheating. Top up coolant as needed and inspect for leaks.
  4. Air Filter and Oil: Like portable generators, standby generators need regular oil changes and air filter inspections. Follow the manufacturer’s guidelines for service intervals and recommended oil types.

Troubleshooting:

  1. Power Failure: If the generator fails to power up during an outage, check the transfer switch and ensure it is functioning correctly. Inspect the fuel supply and ensure there are no leaks or blockages.
  2. Overheating: Overheating can be due to insufficient coolant, blocked ventilation, or a malfunctioning cooling fan. Check coolant levels, inspect the ventilation system, and ensure the fan is working properly.
  3. No Start: If the generator fails to start, inspect the battery, check for error codes on the control panel, and ensure the fuel supply is adequate. A professional may need to diagnose issues with the control board or fuel pump.

Maintaining your standby generator with these practices will ensure that it remains reliable and ready to provide backup power whenever needed.
