FAQ
What is the main advantage of a diesel generator over a gas generator?
Diesel generators are more fuel-efficient, safer to operate, and require less maintenance. They also have a longer lifespan and are more reliable in emergencies.
How often should I maintain my diesel generator?
Regular maintenance should be performed every 100-200 hours of operation, including oil changes, filter replacements, and system checks.
What size generator do I need for my home?
Calculate your total wattage requirements by adding up all essential appliances and devices. Add 20-25% for safety margin and future needs.
Can diesel generators be used indoors?
No, diesel generators should only be used outdoors or in well-ventilated areas due to exhaust emissions and noise levels.
What is the lifespan of a diesel generator?
With proper maintenance, a diesel generator can last 15-20 years or more. Regular maintenance is crucial for maximizing lifespan.
How do I winterize my diesel generator?
Drain the cooling system, add antifreeze, store in a dry place, and run it periodically to prevent fuel degradation.
What safety features should I look for in a diesel generator?
Look for automatic shutdown features, circuit breakers, overload protection, and emergency stop buttons.
Can I run sensitive electronics on a diesel generator?
Yes, but ensure the generator has good voltage regulation and clean power output. Consider using a UPS for additional protection.
How do I choose between a portable and stationary generator?
Consider your mobility needs, available space, and power requirements. Portable units are better for temporary use, while stationary units are ideal for permanent installations.
What should I do if my diesel generator won’t start?
Check the fuel level, battery charge, fuel filters, and air filters. If problems persist, consult a professional technician.
