Backup generators are an essential part of protecting your business from grid failure and natural disasters. Still, most companies don't check or maintain them as rigorously as their main generators. With a regular maintenance routine, you can extend the life of your commercial backup generator and prevent extensive downtime in the future. By following these commercial generator maintenance tips, you can keep your machine running flawlessly for years.

How to Maintain a Backup Generator Daily

You should conduct a visual inspection of your commercial backup generator and check the oil and coolant levels every day. Inspect the alternator, transfer switch and water pump belt to examine their condition, and look underneath the unit for potential leaks. 

Every week, run your generator at a no-load setting and ensure the device is functioning properly. During this time, you should also check the battery charger and inspect the equipment for faulty connections and loose wires.

Establish a Backup Generator Preventative Maintenance Schedule

Your commercial backup generator should include a maintenance routine inside its manual. By following the servicer's proposed maintenance procedures and making daily, monthly and annual generator checkups, you can prevent downtime before it starts and keep your business constantly covered. Depending on your operating conditions, your backup generator may need more or less frequent maintenance.

Using the knowledge from your commercial backup generator's manual and your technical crew, create a maintenance schedule that checks the following equipment components:

  • Battery system
  • Cooling system
  • Engine system
  • Fuel system
  • Lubrication system

If your backup generator is regularly exposed to extreme weather, ambient temperatures, saltwater or airborne contaminants like dust and sand, it is essential to consult with your machine's manufacturers to determine an adequate maintenance schedule. Keeping all information about regular generator maintenance up to date and accurate is also vital to ensuring you receive the benefits of your warranty services.

Perform Generator Set Exercises

If a sudden power outage occurs, your backup generator must be prepared to go from a cold start to fully operational in under a minute. This process is strenuous for the engine, but you can help prepare the system by regularly exercising it. Every month, run the generator for at least 30 minutes while loaded so the fuel system and electrical contacts stay operational and don't deteriorate. Testing the system with actual building loads will allow it to acclimate to automatic transfer switches under strenuous realistic conditions.
