Emergency Power Generators

 

Emergency Power Generators: Choosing the Right Type for Your Needs

Reliable access to emergency power is a cornerstone of preparedness. Whether you're facing hurricanes, winter storms, or unexpected blackouts, the right generator can make a world of difference. In this guide, we’ll explore the key types of generators, how they operate, and what factors to consider before making your purchase.

Types of Generators

Inverter Generators

Inverter generators are known for their compact design, fuel efficiency, and ability to produce clean, stable power—making them ideal for sensitive electronics like laptops, smartphones, and medical devices. They convert AC power to DC and then back to AC, ensuring a consistent output free from harmful fluctuations.

Pros:

• Quiet operation
• Highly fuel-efficient
• Safe for sensitive electronic devices

Cons:

• Higher initial cost
• Lower power output compared to traditional generators

---

Non-Inverter Generators

Traditional non-inverter generators are powerful and cost-effective, better suited for running large appliances and heavy-duty tools during prolonged outages. However, they are less refined in terms of power output, which may affect sensitive electronics.

Pros:

• Higher power output
• Generally more affordable

Cons:

• Noisier operation
• Less fuel-efficient
• Power fluctuations can harm sensitive electronics

Portable vs. Whole House Generators

Portable Generators

Portable generators offer flexibility and can be moved as needed, making them ideal for short-term power needs. They’re perfect for running essential appliances during temporary outages.

Key Considerations:

• Choose models with multiple fuel options (gasoline, propane, or diesel).
• Ensure proper ventilation to prevent carbon monoxide (CO) buildup.

Bonded vs. Unbonded Generators:

• Bonded Generators: These have a neutral wire connected to the frame and are designed for use with a home transfer switch.
• Unbonded Generators: If using a bonded generator as a standalone unit, it must first be converted to an unbonded configuration by disconnecting the neutral wire from the frame.

⚠ Important: Converting a generator from bonded to unbonded should only be done by someone with electrical expertise. Improper handling can create serious safety risks. Never use an unbonded generator as a portable standalone unit without proper grounding, as it can pose a severe shock hazard.

Whole House Generators

Whole house generators are permanently installed systems designed to power an entire home during long-term outages. They automatically kick in when an outage occurs, providing seamless power.

Pros:

• Automatic startup during power loss
• Capable of powering the entire home

Cons:

• High installation costs
• Requires professional setup and ongoing maintenance

---

Fuel Types

• Gasoline: Widely available, but has a shorter shelf life.
• Propane: Cleaner burning with a longer shelf life, but requires special storage tanks.
• Diesel: Highly efficient and suitable for larger generators, though availability may be limited during emergencies.
• Dual/Triple Fuel Generators: These versatile models can run on multiple fuel types, making them ideal for preppers who want flexibility.

Generator Size: Bigger Isn’t Always Better

While larger generators provide more power, they consume more fuel—even at idle. Smaller generators, while more fuel-efficient, may not be capable of running all essential devices at once. The key is to strike a balance: evaluate which appliances you need during an outage and choose a generator size accordingly.

---

Carbon Monoxide Safety

Carbon monoxide (CO) poisoning is a leading cause of death during power outages, often resulting from improper generator use. Always operate generators outdoors, positioned at least 20 feet away from windows, doors, and vents. For added safety, invest in a CO detector—it could be a lifesaver.

Generator Maintenance and Troubleshooting

Ensuring your generator is well-maintained can be the difference between comfort and crisis during an emergency. Here's a practical guide to keeping your generator in top shape and troubleshooting common issues.

---

Preventative Maintenance

Fuel Stabilization:
If your generator uses gasoline, add a fuel stabilizer to prevent gum and varnish buildup during storage. This is especially important if the generator will sit unused for extended periods. Stabilized fuel ensures clean combustion when it's time to start the generator.

Fuel Valve Closure:
Before storing the generator, close the fuel valve and run the engine until it stops. This practice prevents fuel from degrading in the carburetor, which can lead to hard starts and poor performance.

Warm Storage:
In colder climates, store your generator in a warm, dry location to prevent oil thickening, which can hinder starting and damage internal components. Avoid leaving it exposed to moisture, as condensation can lead to corrosion.

Generator Heaters:
For very cold environments, consider using an oil heater or block heater designed for generators. These devices keep the oil at an optimal temperature, making cold starts easier and reducing wear on the engine.

---

Regular Maintenance

1. Oil and Filter Changes:
   Follow the manufacturer's recommended intervals for changing the oil and oil filter. Clean oil reduces engine wear and prolongs the generator’s lifespan.

2. Air Filter Cleaning:
   A clean air filter ensures proper airflow to the engine, improving performance and fuel efficiency. Check the air filter regularly and replace it if it’s clogged or damaged.

3. Spark Plug Inspection:
   Worn or dirty spark plugs can make starting difficult and reduce overall engine efficiency. Replace spark plugs according to the maintenance schedule or if you notice poor performance.

4. Belt and Hose Inspections:
   If your generator uses belts or hoses, check them for signs of cracking, fraying, or other wear. Replace any damaged components to prevent unexpected failures.

---

Troubleshooting Common Issues

1. Clogged Carburetor:
   If your generator won’t start or runs poorly, the carburetor may be clogged due to fuel residue. Cleaning or rebuilding the carburetor can resolve this issue.

2. Faulty CO2 Sensor:
   Diagnosis: If the generator shuts down unexpectedly, a malfunctioning carbon monoxide (CO) sensor could be the problem.
   Testing: Use a multimeter to test the sensor’s resistance. Refer to the generator’s manual for proper testing methods and acceptable resistance values.

3. Old or Stale Gasoline:
   Gasoline degrades over time, causing hard starts and poor performance. If the generator has been sitting unused with old fuel, drain the tank and refill it with fresh, stabilized gasoline.

4. Cold Weather Starting Issues:
   Cold temperatures can make starting difficult. Use high-quality fuel, maintain a charged battery (for electric-start models), and consider adding a winter-grade fuel additive. Preheating the engine with a generator heater can also help.

Generator Output Testing

Using an Outlet Tester:
To ensure your generator is producing clean and stable power, use a dedicated outlet tester. This device can detect issues like improper grounding or incorrect voltage. Regular output checks can prevent damage to sensitive electronics and appliances.
