Frequently Asked Questions

What essential appliances can a 15 kW generator power?

A 15 kW generator provides enough power to run a central air conditioning unit, a refrigerator, a well pump, lights, and several smaller electronics simultaneously. It is sufficient for most whole-house backup needs, though you should always calculate your specific wattage requirements to confirm. For homes with very high demands, exploring models in our high-efficiency guides can help you maximize the power you get from your fuel.

How often should I perform maintenance on my emergency generator?

Regular maintenance is critical for reliability. You should check the oil level before every use and change the oil and filter after the first 20-30 hours of operation, then every 100 hours or at least once per year. Always use fresh, stabilized fuel, and run the generator for at least 30 minutes every month under load to keep the engine components lubricated and the battery charged.
