Generator Buying Guide: Petrol vs Diesel for Kenyan Homes and Businesses

Generator buying guide

Choosing the right generator for your home or business in Kenya is a critical decision that affects both your budget and reliability during power outages. With frequent electricity interruptions and the need for backup power, understanding the differences between petrol and diesel generators can help you make an informed choice. This comprehensive guide covers everything you need to know about generators available in the Kenyan market.

Understanding Kenya's Power Generation Needs

Kenya's electricity supply faces challenges including:

  • Load shedding: Scheduled power outages affecting businesses and homes
  • Grid instability: Voltage fluctuations that can damage equipment
  • Rural electrification gaps: Many areas rely entirely on generators
  • Backup requirements: Critical facilities need reliable backup power
"In my 10 years of power solutions consulting in Kenya, I've seen how the right generator choice can mean the difference between business continuity and costly downtime." - Engineer David Omondi, Power Solutions Expert

Generator maintenance guide

Proper maintenance of your generator is crucial for ensuring reliable backup power when you need it most. In Kenya's challenging environment with dust, humidity, and temperature variations, maintenance becomes even more critical. This guide covers essential maintenance tasks to keep your generator running smoothly.

Why Generator Maintenance Matters

  • Has a significantly longer lifespan
  • Operates more efficiently
  • Requires fewer emergency repairs

Daily Maintenance Routine

For generators in regular use, follow these daily checks:

1. Visual Inspection

Check for obvious signs of damage, leaks, or loose connections. Look for:

  • Oil or fuel leaks
  • Loose bolts or connections
  • Damaged cables or wiring
  • Cracked or damaged housing

2. Fuel Level Check

Ensure adequate fuel for your intended runtime. In Kenya, it's important to use clean, fresh fuel.

Signs It's Time for Professional Service

Take your generator to a professional if you notice:

  • Unusual noises or vibrations
  • Reduced power or performance
  • Overheating during normal use
  • Sparks from the motor area
  • Difficulty starting or inconsistent operation

Storage During Extended Idle Periods

If storing generator for more than 30 days:

  • Add fuel stabilizer and run generator to circulate
  • Drain fuel system if storing longer than 6 months
  • Remove battery and store separately
  • Cover generator to prevent dust accumulation
